javax.swing.tree.DefaultTreeCellRenderer — clojure-interop/javax.swing 1.0.5

Displays an entry in a tree. DefaultTreeCellRenderer is not opaque and unless you subclass paint you should not change this. See How to Use Trees in The Java Tutorial for examples of customizing node display using this class.

The set of icons and colors used by DefaultTreeCellRenderer can be configured using the various setter methods. The value for each property is initialized from the defaults table. When the look and feel changes (updateUI is invoked), any properties that have a value of type UIResource are refreshed from the defaults table. The following table lists the mapping between DefaultTreeCellRenderer property and defaults table key:

Property:
Key:

"leafIcon""Tree.leafIcon" "closedIcon""Tree.closedIcon" "openIcon""Tree.openIcon" "textSelectionColor""Tree.selectionForeground" "textNonSelectionColor""Tree.textForeground" "backgroundSelectionColor""Tree.selectionBackground" "backgroundNonSelectionColor""Tree.textBackground" "borderSelectionColor""Tree.selectionBorderColor"

Implementation Note: This class overrides invalidate, validate, revalidate, repaint, and firePropertyChange solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default tree cell renderer. If you write your own renderer, take care to weigh the benefits and drawbacks of overriding these methods.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

get-preferred-size clj

(get-preferred-size this)

Overrides JComponent.getPreferredSize to return slightly wider preferred size value.

returns: the value of the preferredSize property - java.awt.Dimension

get-text-non-selection-color clj

(get-text-non-selection-color this)

Returns the color the text is drawn with when the node isn't selected.

returns: java.awt.Color

get-text-selection-color clj

(get-text-selection-color this)

get-tree-cell-renderer-component clj

(get-tree-cell-renderer-component this
                                  tree
                                  value
                                  sel

                                  has-focus)

Configures the renderer based on the passed in components. The value is set from messaging the tree with convertValueToText, which ultimately invokes toString on value. The foreground color is set based on the selection and the icon is set based on the leaf and expanded parameters.

tree - javax.swing.JTree value - java.lang.Object sel - boolean expanded - boolean leaf - boolean row - int has-focus - boolean

returns: the Component that the renderer uses to draw the value - java.awt.Component

invalidate clj

(invalidate this)

Overridden for performance reasons. See the Implementation Note for more information.

paint clj

(paint this g)

Paints the value. The background is filled based on selected.

g - the Graphics context in which to paint - java.awt.Graphics

repaint clj

(repaint this)

(repaint this r)

(repaint this tm x y width height)

Overridden for performance reasons. See the Implementation Note for more information.

tm - this parameter is not used - long x - the x value of the dirty region - int y - the y value of the dirty region - int width - the width of the dirty region - int height - the height of the dirty region - int

revalidate clj

(revalidate this)

Overridden for performance reasons. See the Implementation Note for more information.

set-background clj

(set-background this color)

Subclassed to map ColorUIResources to null. If color is null, or a ColorUIResource, this has the effect of letting the background color of the JTree show through. On the other hand, if color is non-null, and not a ColorUIResource, the background becomes color.

color - the desired background Color - java.awt.Color

Sets the background color to be used for non selected nodes.

set-background-selection-color clj

(set-background-selection-color this new-color)

Sets the color to use for the background if node is selected.

new-color - java.awt.Color

set-border-selection-color clj

(set-border-selection-color this new-color)

Sets the color to use for the border.

new-color - java.awt.Color

set-closed-icon clj

(set-closed-icon this new-icon)

Sets the icon used to represent non-leaf nodes that are not expanded.

new-icon - javax.swing.Icon

set-font clj

(set-font this font)

Subclassed to map FontUIResources to null. If font is null, or a FontUIResource, this has the effect of letting the font of the JTree show through. On the other hand, if font is non-null, and not a FontUIResource, the font becomes font.

font - the desired Font for this component - java.awt.Font

set-leaf-icon clj
