                  multivalent.gui.VTextArea

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

VEntry

public class VTextArea

extends IScrollPane

Editable area (not necessarily all text). Depends on other behaviors, such as BindingsDefault and BindingsEmacs, for key bindings, and other nodes to display content.

Content kept as subtree, available as string from getContent().

Method Summary

boolean	breakAfter()
boolean	breakBefore()
boolean	eventNode(java.awt.AWTEvent e, java.awt.Point rel) If no content, route mouse to 0-length leaf, so can click and type.
protected void	fixContent() appendChild() adds to formatting node, which is VTextArea's first and only child, instead.
boolean	formatNode(int width, int height, Context cx) If length of dimension set in characters or to dynamic (these mutually cancel each other out--last one set wins), use that to set corresponding bounding box dimension.
java.lang.String	getContent() Collect up textual leaves into a space-separated String.
void	paintNode(java.awt.Rectangle docclip, Context cx) Paints contents in scrolled, clipped Graphics2D.

Constructor Detail

VTextArea

public VTextArea(java.lang.String name,
                 java.util.Map<java.lang.String,java.lang.Object> attr,
                 INode parent)

VTextArea

public VTextArea(java.lang.String name,
                 java.util.Map<java.lang.String,java.lang.Object> attr,
                 INode parent,
                 INode layout)

Parameters:

layout - INode, defaults to IParaBox. Content should be added to this node, which should be the single child of VTextArea.

Method Detail

fixContent

protected void fixContent()

appendChild() adds to formatting node, which is VTextArea's first and only child, instead.

formatNode

public boolean formatNode(int width,
                          int height,
                          Context cx)

Description copied from class: IScrollPane

If length of dimension set in characters or to dynamic (these mutually cancel each other out--last one set wins), use that to set corresponding bounding box dimension. Else maintain length, which should have been set externally beforehand. Sends IScrollPane.MSG_FORMATTED.

Overrides:

formatNode in class IScrollPane
