Method Detail

invalidateMetrics

protected void invalidateMetrics()

Overrides:

invalidateMetrics in class TextInputControlSkin<TextArea,TextAreaBehavior>

layoutChildren

protected void layoutChildren(double contentX,
                              double contentY,
                              double contentWidth,
                              double contentHeight)

Description copied from class: SkinBase

Called during the layout pass of the scenegraph.

Overrides:

layoutChildren in class SkinBase<TextArea>

dispose

public void dispose()

Description copied from class: BehaviorSkinBase

Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methods Skin.getSkinnable() and Skin.getNode() should return null following a call to dispose. Calling dispose twice has no effect.

Specified by:

dispose in interface Skin<TextArea>

Overrides:

dispose in class BehaviorSkinBase<TextArea,TextAreaBehavior>

computeBaselineOffset

public double computeBaselineOffset(double topInset,
                                    double rightInset,
                                    double bottomInset,
                                    double leftInset)

Description copied from class: SkinBase

Calculates the baseline offset based on the first managed child. If there is no such child, returns Node.getBaselineOffset().

Overrides:

computeBaselineOffset in class SkinBase<TextArea>

Parameters:

topInset - the pixel snapped top inset

rightInset - the pixel snapped right inset

bottomInset - the pixel snapped bottom inset

leftInset - the pixel snapped left inset

Returns:

baseline offset

getCharacter
