Method Detail

performEdit

protected javax.swing.undo.UndoableEdit performEdit(boolean selected)

Description copied from class: UndoableToggleCommand

Subclasses must override to perform the actual edit. This method behaves similar to 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);
    }
 }
 

Specified by:

performEdit in class UndoableToggleCommand

Parameters:

selected - the new selected state of the command.

Returns:

an UndoableEdit object that can undo and redo the commands action.
