Class org.aswing.FlowLayout

Description

A flow layout arranges components in a left-to-right flow, much like lines of text in a paragraph. Flow layouts are typically used to arrange buttons in a panel. It will arrange buttons left to right until no more buttons fit on the same line. Each line is centered.

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

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

Constructor Detail

FlowLayout

public function FlowLayout(align:Number, hgap:Number, vgap:Number)

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, or FlowLayout.CENTER.

Parameters

alignthe alignment value, default is LEFT
hgapthe horizontal gap between components, default 5
vgapthe vertical gap between components, default 5

Field Detail

LEFT

static public LEFT:Number
This value indicates that each row of components should be left-justified.

CENTER

static public CENTER:Number
This value indicates that each row of components should be centered.

RIGHT

static public RIGHT:Number
This value indicates that each row of components should be right-justified.

preferredLayoutSize

public function preferredLayoutSize(target:Container):Dimension

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

Parameters

targetthe component which needs to be laid out

Return

the preferred dimensions to lay out the subcomponents of the specified container

Specified By

preferredLayoutSize() in org.aswing.LayoutManager

Overrides

preferredLayoutSize() in org.aswing.EmptyLayout
