Constructor Detail

TreeCellSkin

public TreeCellSkin(<any> control)

Creates a new TreeCellSkin instance, installing the necessary child nodes into the Control children list, as well as the necessary input mappings for handling key, mouse, etc events.

Parameters:

control - The control that this skin should be installed onto.

Method Detail

setupTreeViewListeners

private void setupTreeViewListeners()

setIndent

public final void setIndent(double value)

Sets the value of the property indent.

getIndent

public final double getIndent()

Gets the value of the property indent.

indentProperty

public final DoubleProperty indentProperty()

The amount of space to multiply by the treeItem.level to get the left margin for this tree cell. This is settable from CSS

getIndent(), setIndent(double)

dispose

public void dispose()

updateChildren

protected void updateChildren()

Updates the children managed by LabeledSkinBase, which can be the Labeled graphic and/or a Text node. Only those nodes which actually must be used are used. For example, with a ContentDisplay of GRAPHIC_ONLY the text node is not added, and with a ContentDisplay of TEXT_ONLY, the graphic is not added.

Overrides:

updateChildren in class LabeledSkinBase<<any>>

layoutChildren

protected void layoutChildren(double x,
                              double y,

                              double h)

The Layout algorithm works like this: - Get the labeled w/h, graphic w/h, text w/h - Compute content w/h based on graphicVPos, graphicHPos, graphicTextGap, and graphic w/h and text w/h - (Note that the text content has been pre-truncated where necessary) - compute content x/y based on content w/h and labeled w/h and the labeled's hpos and vpos - position the graphic and text
