protected javax.swing.undo.UndoableEdit performEdit(boolean selected)
UndoableToggleCommand
ToggleCommand.handleSelection(boolean)
in that it can throw a ToggleVetoException
to cancel the edit.
Please note that the edit object should call ToggleCommand.applySelection(boolean)
to update the state of this command
without causing a new UndoableEdit to be created. For example
class MyToggle.ToggleUndoableEdit extends UndoableEdit { public void undo() { // undo any command specific stuff... ... // and reset our state without causeing any side effects.. applySelection(oldState); } }
performEdit
in class UndoableToggleCommand
selected
- the new selected state of the command.
ToggleCommand.applySelection(boolean)
