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

A flow layout arranges components in a directional flow, much like lines of text in a paragraph. The flow direction is determined by the container's componentOrientation property and may be one of two values:

ComponentOrientation.LEFT_TO_RIGHT ComponentOrientation.RIGHT_TO_LEFT

Flow layouts are typically used to arrange buttons in a panel. It arranges buttons horizontally until no more buttons fit on the same line. The line alignment is determined by the align property. The possible values are:

LEFT RIGHT CENTER LEADING TRAILING

For example, the following picture shows an applet using the flow layout manager (its default layout manager) to position three buttons:

Here is the code for this applet:

import java.awt.*; import java.applet.Applet;

public class myButtons extends Applet { Button button1, button2, button3; public void init() { button1 = new Button("Ok"); button2 = new Button("Open"); button3 = new Button("Close"); add(button1); add(button2); add(button3); } }

A flow layout lets each component assume its natural (preferred) size.

*-center clj

Static Constant.

This value indicates that each row of components should be centered.

type: int

*-leading clj

Static Constant.

This value indicates that each row of components should be justified to the leading edge of the container's orientation, for example, to the left in left-to-right orientations.

type: int

*-left clj

Static Constant.

This value indicates that each row of components should be left-justified.

type: int

*-right clj

Static Constant.

This value indicates that each row of components should be right-justified.

type: int

*-trailing clj

Static Constant.

This value indicates that each row of components should be justified to the trailing edge of the container's orientation, for example, to the right in left-to-right orientations.

type: int

->flow-layout clj

(->flow-layout)

(->flow-layout align)

(->flow-layout align hgap vgap)

Constructor.

Creates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.

The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.

align - the alignment value - int hgap - the horizontal gap between components and between the components and the borders of the Container - int vgap - the vertical gap between components and between the components and the borders of the Container - int

add-layout-component clj

(add-layout-component this name comp)

Adds the specified component to the layout. Not used by this class.

name - the name of the component - java.lang.String comp - the component to be added - java.awt.Component

get-align-on-baseline? clj

(get-align-on-baseline? this)

Returns true if components are to be vertically aligned along their baseline. The default is false.

returns: true if components are to be vertically aligned along their baseline - boolean

get-alignment clj

(get-alignment this)

Gets the alignment for this layout. Possible values are FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.

returns: the alignment value for this layout - int

get-hgap clj

(get-hgap this)

Gets the horizontal gap between components and between the components and the borders of the Container

returns: the horizontal gap between components and between the components and the borders of the Container - int

get-vgap clj

(get-vgap this)

Gets the vertical gap between components and between the components and the borders of the Container.

returns: the vertical gap between components and between the components and the borders of the Container - int

layout-container clj

(layout-container this target)

Lays out the container. This method lets each visible component take its preferred size by reshaping the components in the target container in order to satisfy the alignment of this FlowLayout object.

target - the specified component being laid out - java.awt.Container

minimum-layout-size clj

(minimum-layout-size this target)

Returns the minimum dimensions needed to layout the visible components contained in the specified target container.

target - the container that needs to be laid out - java.awt.Container

returns: the minimum dimensions to lay out the subcomponents of the specified container - java.awt.Dimension

preferred-layout-size clj

(preferred-layout-size this target)

Returns the preferred dimensions for this layout given the visible components in the specified target container.

target - the container that needs to be laid out - java.awt.Container

returns: the preferred dimensions to lay out the subcomponents of the specified container - java.awt.Dimension

remove-layout-component clj

(remove-layout-component this comp)

Removes the specified component from the layout. Not used by this class.

comp - the component to remove - java.awt.Component

set-align-on-baseline clj

(set-align-on-baseline this align-on-baseline)

Sets whether or not components should be vertically aligned along their baseline. Components that do not have a baseline will be centered. The default is false.

align-on-baseline - whether or not components should be vertically aligned on their baseline - boolean

set-alignment clj

(set-alignment this align)

Sets the alignment for this layout. Possible values are

FlowLayout.LEFT FlowLayout.RIGHT FlowLayout.CENTER FlowLayout.LEADING FlowLayout.TRAILING

align - one of the alignment values shown above - int

set-hgap clj

(set-hgap this hgap)

Sets the horizontal gap between components and between the components and the borders of the Container.

hgap - the horizontal gap between components and between the components and the borders of the Container - int

set-vgap clj

(set-vgap this vgap)

Sets the vertical gap between components and between the components and the borders of the Container.

vgap - the vertical gap between components and between the components and the borders of the Container - int

to-string clj

(to-string this)

Returns a string representation of this FlowLayout object and its values.

returns: a string representation of this layout - java.lang.String
