jdk.awt.Toolkit — clojure-interop/java.awt 1.0.5

This class is the abstract superclass of all actual implementations of the Abstract Window Toolkit. Subclasses of the Toolkit class are used to bind the various components to particular native toolkit implementations.

Many GUI events may be delivered to user asynchronously, if the opposite is not specified explicitly. As well as many GUI operations may be performed asynchronously. This fact means that if the state of a component is set, and then the state immediately queried, the returned value may not yet reflect the requested change. This behavior includes, but is not limited to:

Scrolling to a specified position. For example, calling ScrollPane.setScrollPosition and then getScrollPosition may return an incorrect value if the original request has not yet been processed.

Moving the focus from one component to another. For more information, see Timing Focus Transfers, a section in The Swing Tutorial.

Making a top-level container visible. Calling setVisible(true) on a Window, Frame or Dialog may occur asynchronously.

Setting the size or location of a top-level container. Calls to setSize, setBounds or setLocation on a Window, Frame or Dialog are forwarded to the underlying window management system and may be ignored or modified. See Window for more information.

Most applications should not call any of the methods in this class directly. The methods defined by Toolkit are the "glue" that joins the platform-independent classes in the java.awt package with their counterparts in java.awt.peer. Some methods defined by Toolkit query the native operating system directly.

*get-default-toolkit clj

(*get-default-toolkit)

Gets the default toolkit.

If a system property named "java.awt.headless" is set to true then the headless implementation of Toolkit is used.

If there is no "java.awt.headless" or it is set to false and there is a system property named "awt.toolkit", that property is treated as the name of a class that is a subclass of Toolkit; otherwise the default platform-specific implementation of Toolkit is used.

Also loads additional classes into the VM, using the property 'assistive_technologies' specified in the Sun reference implementation by a line in the 'accessibility.properties' file. The form is "assistive_technologies=..." where the "..." is a comma-separated list of assistive technology classes to load. Each class is loaded in the order given and a single instance of each is created using Class.forName(class).newInstance(). This is done just after the AWT toolkit is created. All errors are handled via an AWTError exception.

returns: the default toolkit. - java.awt.Toolkit

throws: java.awt.AWTError - if a toolkit could not be found, or if one could not be accessed or instantiated.

*get-property clj

(*get-property key default-value)

Gets a property with the specified key and default. This method returns defaultValue if the property is not found.

key - java.lang.String default-value - java.lang.String

returns: java.lang.String

->toolkit clj

(->toolkit)

Constructor.

add-awt-event-listener clj

(add-awt-event-listener this listener event-mask)

Adds an AWTEventListener to receive all AWTEvents dispatched system-wide that conform to the given eventMask.

First, if there is a security manager, its checkPermission method is called with an AWTPermission("listenToAllAWTEvents") permission. This may result in a SecurityException.

eventMask is a bitmask of event types to receive. It is constructed by bitwise OR-ing together the event masks defined in AWTEvent.

Note: event listener use is not recommended for normal application use, but are intended solely to support special purpose facilities including support for accessibility, event record/playback, and diagnostic tracing.

If listener is null, no exception is thrown and no action is performed.

listener - the event listener. - java.awt.event.AWTEventListener event-mask - the bitmask of event types to receive - long

throws: java.lang.SecurityException - if a security manager exists and its checkPermission method doesn't allow the operation.

add-property-change-listener clj

(add-property-change-listener this name pcl)

Adds the specified property change listener for the named desktop property. When a PropertyChangeListenerProxy object is added, its property name is ignored, and the wrapped listener is added. If name is null or pcl is null, no exception is thrown and no action is performed.

name - The name of the property to listen for - java.lang.String pcl - The property change listener - java.beans.PropertyChangeListener

always-on-top-supported? clj

(always-on-top-supported? this)

Returns whether the always-on-top mode is supported by this toolkit. To detect whether the always-on-top mode is supported for a particular Window, use Window.isAlwaysOnTopSupported().

returns: true, if current toolkit supports the always-on-top mode, otherwise returns false - boolean

are-extra-mouse-buttons-enabled clj

(are-extra-mouse-buttons-enabled this)

Reports whether events from extra mouse buttons are allowed to be processed and posted into EventQueue.

To change the returned value it is necessary to set the sun.awt.enableExtraMouseButtons property before the Toolkit class initialization. This setting could be done on the application startup by the following command:

java -Dsun.awt.enableExtraMouseButtons=false Application Alternatively, the property could be set in the application by using the following code:

System.setProperty("sun.awt.enableExtraMouseButtons", "true"); before the Toolkit class initialization. If not set by the time of the Toolkit class initialization, this property will be initialized with true. Changing this value after the Toolkit class initialization will have no effect.

returns: true if events from extra mouse buttons are allowed to be processed and posted; false otherwise - boolean

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

beep clj

(beep this)

Emits an audio beep depending on native system settings and hardware capabilities.

check-image clj

(check-image this image width height observer)

Indicates the construction status of a specified image that is being prepared for display.

If the values of the width and height arguments are both -1, this method returns the construction status of a screen representation of the specified image in this toolkit. Otherwise, this method returns the construction status of a scaled representation of the image at the specified width and height.

This method does not cause the image to begin loading. An application must call prepareImage to force the loading of an image.

This method is called by the component's checkImage methods.

Information on the flags returned by this method can be found with the definition of the ImageObserver interface.

image - the image whose status is being checked. - java.awt.Image width - the width of the scaled version whose status is being checked, or -1. - int height - the height of the scaled version whose status is being checked, or -1. - int observer - the ImageObserver object to be notified as the image is being prepared. - java.awt.image.ImageObserver

returns: the bitwise inclusive OR of the ImageObserver flags for the image data that is currently available. - int

create-custom-cursor clj

(create-custom-cursor this cursor hot-spot name)

Creates a new custom cursor object. If the image to display is invalid, the cursor will be hidden (made completely transparent), and the hotspot will be set to (0, 0).

Note that multi-frame images are invalid and may cause this method to hang.

cursor - the image to display when the cursor is activated - java.awt.Image hot-spot - the X and Y of the large cursor's hot spot; the hotSpot values must be less than the Dimension returned by getBestCursorSize - java.awt.Point name - a localized description of the cursor, for Java Accessibility use - java.lang.String

returns: java.awt.Cursor

throws: java.lang.IndexOutOfBoundsException - if the hotSpot values are outside the bounds of the cursor

create-drag-gesture-recognizer clj

(create-drag-gesture-recognizer this
                                abstract-recognizer-class
                                ds
                                c
                                src-actions
                                dgl)

Creates a concrete, platform dependent, subclass of the abstract DragGestureRecognizer class requested, and associates it with the DragSource, Component and DragGestureListener specified.

subclasses should override this to provide their own implementation

abstract-recognizer-class - The abstract class of the required recognizer - java.lang.Class ds - The DragSource - java.awt.dnd.DragSource c - The Component target for the DragGestureRecognizer - java.awt.Component src-actions - The actions permitted for the gesture - int dgl - The DragGestureListener - java.awt.dnd.DragGestureListener

returns: the new object or null. Always returns null if GraphicsEnvironment.isHeadless() returns true. - <T extends java.awt.dnd.DragGestureRecognizer> T

create-drag-source-context-peer clj

(create-drag-source-context-peer this dge)

Creates the peer for a DragSourceContext. Always throws InvalidDndOperationException if GraphicsEnvironment.isHeadless() returns true.

dge - java.awt.dnd.DragGestureEvent

returns: java.awt.dnd.peer.DragSourceContextPeer

throws: java.awt.dnd.InvalidDnDOperationException

create-image clj

(create-image this filename)

(create-image this imagedata imageoffset imagelength)

Creates an image which decodes the image stored in the specified byte array, and at the specified offset and length. The data must be in some image format, such as GIF or JPEG, that is supported by this toolkit.

imagedata - an array of bytes, representing image data in a supported image format. - byte[] imageoffset - the offset of the beginning of the data in the array. - int imagelength - the length of the data in the array. - int

returns: an image. - java.awt.Image

dynamic-layout-active? clj

(dynamic-layout-active? this)

Returns whether dynamic layout of Containers on resize is currently active (both set in program ( isDynamicLayoutSet() ) , and supported by the underlying operating system and/or window manager). If dynamic layout is currently inactive then Containers re-layout their components when resizing is completed. As a result the Component.validate() method will be invoked only once per resize. If dynamic layout is currently active then Containers re-layout their components on every native resize event and the validate() method will be invoked each time. The OS/WM support can be queried using the getDesktopProperty("awt.dynamicLayoutSupported") method.

returns: true if dynamic layout of Containers on resize is currently active, false otherwise. - boolean

throws: java.awt.HeadlessException - if the GraphicsEnvironment.isHeadless() method returns true

frame-state-supported? clj

(frame-state-supported? this state)

Returns whether Toolkit supports this state for Frames. This method tells whether the UI concept of, say, maximization or iconification is supported. It will always return false for "compound" states like Frame.ICONIFIED|Frame.MAXIMIZED_VERT. In other words, the rule of thumb is that only queries with a single frame state constant as an argument are meaningful. Note that supporting a given concept is a platform- dependent feature. Due to native limitations the Toolkit object may report a particular state as supported, however at the same time the Toolkit object will be unable to apply the state to a given frame. This circumstance has two following consequences:

Only the return value of false for the present method actually indicates that the given state is not supported. If the method returns true the given state may still be unsupported and/or unavailable for a particular frame. The developer should consider examining the value of the WindowEvent.getNewState() method of the WindowEvent received through the WindowStateListener, rather than assuming that the state given to the setExtendedState() method will be definitely applied. For more information see the documentation for the Frame.setExtendedState(int) method.

state - one of named frame state constants. - int

returns: true is this frame state is supported by this Toolkit implementation, false otherwise. - boolean

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true.

get-awt-event-listeners clj

(get-awt-event-listeners this)

(get-awt-event-listeners this event-mask)

Returns an array of all the AWTEventListeners registered on this toolkit which listen to all of the event types specified in the eventMask argument. If there is a security manager, its checkPermission method is called with an AWTPermission("listenToAllAWTEvents") permission. This may result in a SecurityException. Listeners can be returned within AWTEventListenerProxy objects, which also contain the event mask for the given listener. Note that listener objects added multiple times appear only once in the returned array.

event-mask - the bitmask of event types to listen for - long

returns: all of the AWTEventListeners registered on this toolkit for the specified event types, or an empty array if no such listeners are currently registered - java.awt.event.AWTEventListener[]

throws: java.lang.SecurityException - if a security manager exists and its checkPermission method doesn't allow the operation.

get-best-cursor-size clj

(get-best-cursor-size this preferred-width preferred-height)

Returns the supported cursor dimension which is closest to the desired sizes. Systems which only support a single cursor size will return that size regardless of the desired sizes. Systems which don't support custom cursors will return a dimension of 0, 0. Note: if an image is used whose dimensions don't match a supported size (as returned by this method), the Toolkit implementation will attempt to resize the image to a supported size. Since converting low-resolution images is difficult, no guarantees are made as to the quality of a cursor image which isn't a supported size. It is therefore recommended that this method be called and an appropriate image used so no image conversion is made.

preferred-width - the preferred cursor width the component would like to use. - int preferred-height - the preferred cursor height the component would like to use. - int

returns: the closest matching supported cursor size, or a dimension of 0,0 if the Toolkit implementation doesn't support custom cursors. - java.awt.Dimension

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-color-model clj

(get-color-model this)

Determines the color model of this toolkit's screen.

ColorModel is an abstract class that encapsulates the ability to translate between the pixel values of an image and its red, green, blue, and alpha components.

This toolkit method is called by the getColorModel method of the Component class.

returns: the color model of this toolkit's screen. - java.awt.image.ColorModel

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-desktop-property clj

(get-desktop-property this property-name)

Obtains a value for the specified desktop property.

A desktop property is a uniquely named value for a resource that is Toolkit global in nature. Usually it also is an abstract representation for an underlying platform dependent desktop setting. For more information on desktop properties supported by the AWT see AWT Desktop Properties.

property-name - java.lang.String

returns: java.lang.Object

get-font-list clj

(get-font-list this)

Deprecated. see GraphicsEnvironment.getAvailableFontFamilyNames()

returns: the names of the available fonts in this toolkit. - java.lang.String[]

get-font-metrics clj

(get-font-metrics this font)

Deprecated. As of JDK version 1.2, replaced by the Font method getLineMetrics.

font - a font - java.awt.Font

returns: the screen metrics of the specified font in this toolkit - java.awt.FontMetrics

get-image clj

(get-image this filename)

Returns an image which gets pixel data from the specified file, whose format can be either GIF, JPEG or PNG. The underlying toolkit attempts to resolve multiple requests with the same filename to the same returned Image.

Since the mechanism required to facilitate this sharing of Image objects may continue to hold onto images that are no longer in use for an indefinite period of time, developers are encouraged to implement their own caching of images by using the createImage variant wherever available. If the image data contained in the specified file changes, the Image object returned from this method may still contain stale information which was loaded from the file after a prior call. Previously loaded image data can be manually discarded by calling the flush method on the returned Image.

This method first checks if there is a security manager installed. If so, the method calls the security manager's checkRead method with the file specified to ensure that the access to the image is allowed.

filename - the name of a file containing pixel data in a recognized file format. - java.lang.String

returns: an image which gets its pixel data from the specified file. - java.awt.Image

throws: java.lang.SecurityException - if a security manager exists and its checkRead method doesn't allow the operation.

get-locking-key-state? clj

(get-locking-key-state? this key-code)

Returns whether the given locking key on the keyboard is currently in its "on" state. Valid key codes are VK_CAPS_LOCK, VK_NUM_LOCK, VK_SCROLL_LOCK, and VK_KANA_LOCK.

key-code - int

returns: boolean

throws: java.lang.IllegalArgumentException - if keyCode is not one of the valid key codes

get-maximum-cursor-colors clj

(get-maximum-cursor-colors this)

Returns the maximum number of colors the Toolkit supports in a custom cursor palette. Note: if an image is used which has more colors in its palette than the supported maximum, the Toolkit implementation will attempt to flatten the palette to the maximum. Since converting low-resolution images is difficult, no guarantees are made as to the quality of a cursor image which has more colors than the system supports. It is therefore recommended that this method be called and an appropriate image used so no image conversion is made.

returns: the maximum number of colors, or zero if custom cursors are not supported by this Toolkit implementation. - int

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-menu-shortcut-key-mask clj

(get-menu-shortcut-key-mask this)

Determines which modifier key is the appropriate accelerator key for menu shortcuts.

Menu shortcuts, which are embodied in the MenuShortcut class, are handled by the MenuBar class.

By default, this method returns Event.CTRL_MASK. Toolkit implementations should override this method if the Control key isn't the correct key for accelerators.

returns: the modifier mask on the Event class that is used for menu shortcuts on this toolkit. - int

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-print-job clj

(get-print-job this frame jobtitle props)

(get-print-job this frame jobtitle job-attributes page-attributes)

Gets a PrintJob object which is the result of initiating a print operation on the toolkit's platform.

Each actual implementation of this method should first check if there is a security manager installed. If there is, the method should call the security manager's checkPrintJobAccess method to ensure initiation of a print operation is allowed. If the default implementation of checkPrintJobAccess is used (that is, that method is not overriden), then this results in a call to the security manager's checkPermission method with a RuntimePermission("queuePrintJob") permission.

frame - the parent of the print dialog. May not be null. - java.awt.Frame jobtitle - the title of the PrintJob. A null title is equivalent to "". - java.lang.String job-attributes - a set of job attributes which will control the PrintJob. The attributes will be updated to reflect the user's choices as outlined in the JobAttributes documentation. May be null. - java.awt.JobAttributes page-attributes - a set of page attributes which will control the PrintJob. The attributes will be applied to every page in the job. The attributes will be updated to reflect the user's choices as outlined in the PageAttributes documentation. May be null. - java.awt.PageAttributes

returns: a PrintJob object, or null if the user cancelled the print job. - java.awt.PrintJob

throws: java.lang.NullPointerException - if frame is null

get-property-change-listeners clj

(get-property-change-listeners this)

(get-property-change-listeners this property-name)

Returns an array of all property change listeners associated with the specified name of a desktop property.

property-name - the named property - java.lang.String

returns: all of the PropertyChangeListener objects associated with the specified name of a desktop property or an empty array if no such listeners are added - java.beans.PropertyChangeListener[]

get-screen-insets clj

(get-screen-insets this gc)

Gets the insets of the screen.

gc - a GraphicsConfiguration - java.awt.GraphicsConfiguration

returns: the insets of this toolkit's screen, in pixels. - java.awt.Insets

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-screen-resolution clj

(get-screen-resolution this)

Returns the screen resolution in dots-per-inch.

returns: this toolkit's screen resolution, in dots-per-inch. - int

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-screen-size clj

(get-screen-size this)

Gets the size of the screen. On systems with multiple displays, the primary display is used. Multi-screen aware display dimensions are available from GraphicsConfiguration and GraphicsDevice.

returns: the size of this toolkit's screen, in pixels. - java.awt.Dimension

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-system-clipboard clj

(get-system-clipboard this)

Gets the singleton instance of the system Clipboard which interfaces with clipboard facilities provided by the native platform. This clipboard enables data transfer between Java programs and native applications which use native clipboard facilities.

In addition to any and all formats specified in the flavormap.properties file, or other file specified by the AWT.DnD.flavorMapFileURL Toolkit property, text returned by the system Clipboard's getTransferData() method is available in the following flavors:

DataFlavor.stringFlavor DataFlavor.plainTextFlavor (deprecated)

As with java.awt.datatransfer.StringSelection, if the requested flavor is DataFlavor.plainTextFlavor, or an equivalent flavor, a Reader is returned. Note: The behavior of the system Clipboard's getTransferData() method for DataFlavor.plainTextFlavor, and equivalent DataFlavors, is inconsistent with the definition of DataFlavor.plainTextFlavor . Because of this, support for DataFlavor.plainTextFlavor, and equivalent flavors, is deprecated.

Each actual implementation of this method should first check if there is a security manager installed. If there is, the method should call the security manager's checkPermission method to check AWTPermission("accessClipboard").

returns: the system Clipboard - java.awt.datatransfer.Clipboard

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

get-system-event-queue clj

(get-system-event-queue this)

Get the application's or applet's EventQueue instance. Depending on the Toolkit implementation, different EventQueues may be returned for different applets. Applets should therefore not assume that the EventQueue instance returned by this method will be shared by other applets or the system.

If there is a security manager then its checkPermission method is called to check AWTPermission("accessEventQueue").

returns: the EventQueue object - java.awt.EventQueue

throws: java.lang.SecurityException - if a security manager is set and it denies access to the EventQueue

get-system-selection clj

(get-system-selection this)

Gets the singleton instance of the system selection as a Clipboard object. This allows an application to read and modify the current, system-wide selection.

An application is responsible for updating the system selection whenever the user selects text, using either the mouse or the keyboard. Typically, this is implemented by installing a FocusListener on all Components which support text selection, and, between FOCUS_GAINED and FOCUS_LOST events delivered to that Component, updating the system selection Clipboard when the selection changes inside the Component. Properly updating the system selection ensures that a Java application will interact correctly with native applications and other Java applications running simultaneously on the system. Note that java.awt.TextComponent and javax.swing.text.JTextComponent already adhere to this policy. When using these classes, and their subclasses, developers need not write any additional code.

Some platforms do not support a system selection Clipboard. On those platforms, this method will return null. In such a case, an application is absolved from its responsibility to update the system selection Clipboard as described above.

Each actual implementation of this method should first check if there is a security manager installed. If there is, the method should call the security manager's checkPermission method to check AWTPermission("accessClipboard").

returns: the system selection as a Clipboard, or null if the native platform does not support a system selection Clipboard - java.awt.datatransfer.Clipboard

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

map-input-method-highlight clj

(map-input-method-highlight this highlight)

Returns a map of visual attributes for the abstract level description of the given input method highlight, or null if no mapping is found. The style field of the input method highlight is ignored. The map returned is unmodifiable.

highlight - input method highlight - java.awt.im.InputMethodHighlight

returns: style attribute map, or null - java.util.Map<java.awt.font.TextAttribute,?>

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless returns true

modal-exclusion-type-supported? clj

(modal-exclusion-type-supported? this modal-exclusion-type)

Returns whether the given modal exclusion type is supported by this toolkit. If an unsupported modal exclusion type property is set on a window, then Dialog.ModalExclusionType.NO_EXCLUDE is used instead.

modal-exclusion-type - modal exclusion type to be checked for support by this toolkit - java.awt.Dialog$ModalExclusionType

returns: true, if current toolkit supports given modal exclusion type, false otherwise - boolean

modality-type-supported? clj

(modality-type-supported? this modality-type)

Returns whether the given modality type is supported by this toolkit. If a dialog with unsupported modality type is created, then Dialog.ModalityType.MODELESS is used instead.

modality-type - modality type to be checked for support by this toolkit - java.awt.Dialog$ModalityType

returns: true, if current toolkit supports given modality type, false otherwise - boolean

prepare-image clj

(prepare-image this image width height observer)

Prepares an image for rendering.

If the values of the width and height arguments are both -1, this method prepares the image for rendering on the default screen; otherwise, this method prepares an image for rendering on the default screen at the specified width and height.

The image data is downloaded asynchronously in another thread, and an appropriately scaled screen representation of the image is generated.

This method is called by components prepareImage methods.

Information on the flags returned by this method can be found with the definition of the ImageObserver interface.

image - the image for which to prepare a screen representation. - java.awt.Image width - the width of the desired screen representation, or -1. - int height - the height of the desired screen representation, or -1. - int observer - the ImageObserver object to be notified as the image is being prepared. - java.awt.image.ImageObserver

returns: true if the image has already been fully prepared; false otherwise. - boolean

remove-awt-event-listener clj

(remove-awt-event-listener this listener)

Removes an AWTEventListener from receiving dispatched AWTEvents.

First, if there is a security manager, its checkPermission method is called with an AWTPermission("listenToAllAWTEvents") permission. This may result in a SecurityException.

Note: event listener use is not recommended for normal application use, but are intended solely to support special purpose facilities including support for accessibility, event record/playback, and diagnostic tracing.

If listener is null, no exception is thrown and no action is performed.

listener - the event listener. - java.awt.event.AWTEventListener

throws: java.lang.SecurityException - if a security manager exists and its checkPermission method doesn't allow the operation.

remove-property-change-listener clj

(remove-property-change-listener this name pcl)

Removes the specified property change listener for the named desktop property. When a PropertyChangeListenerProxy object is removed, its property name is ignored, and the wrapped listener is removed. If name is null or pcl is null, no exception is thrown and no action is performed.

name - The name of the property to remove - java.lang.String pcl - The property change listener - java.beans.PropertyChangeListener

set-dynamic-layout clj

(set-dynamic-layout this dynamic)

Controls whether the layout of Containers is validated dynamically during resizing, or statically, after resizing is complete. Use isDynamicLayoutActive() to detect if this feature enabled in this program and is supported by this operating system and/or window manager. Note that this feature is supported not on all platforms, and conversely, that this feature cannot be turned off on some platforms. On these platforms where dynamic layout during resizing is not supported (or is always supported), setting this property has no effect. Note that this feature can be set or unset as a property of the operating system or window manager on some platforms. On such platforms, the dynamic resize property must be set at the operating system or window manager level before this method can take effect. This method does not change support or settings of the underlying operating system or window manager. The OS/WM support can be queried using getDesktopProperty("awt.dynamicLayoutSupported") method.

dynamic - If true, Containers should re-layout their components as the Container is being resized. If false, the layout will be validated after resizing is completed. - boolean

throws: java.awt.HeadlessException - if GraphicsEnvironment.isHeadless() returns true

set-locking-key-state clj

(set-locking-key-state this key-code on)

Sets the state of the given locking key on the keyboard. Valid key codes are VK_CAPS_LOCK, VK_NUM_LOCK, VK_SCROLL_LOCK, and VK_KANA_LOCK.

Depending on the platform, setting the state of a locking key may involve event processing and therefore may not be immediately observable through getLockingKeyState.

key-code - int on - boolean

throws: java.lang.IllegalArgumentException - if keyCode is not one of the valid key codes

sync clj

(sync this)

Synchronizes this toolkit's graphics state. Some window systems may do buffering of graphics events.

This method ensures that the display is up-to-date. It is useful for animation.
