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:

                                    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:
