Method Detail

clearUndo

public void clearUndo()

Clears the undo stack

startCombiningEdits

public void startCombiningEdits()

Calling this causes the undoable edits to be combined until commitCombinedEdits() is called. This allows the user of this support to perform multiple edits to the JTextComponent and wrap them together in the undo stack. It is left to the user of this class to be sure that the edits can be combined. If edits are already being combined this method does nothing and edits will continue to be combined.

commitCombinedEdit

public void commitCombinedEdit()

Commits the combined edits (if any) that have been accrued since startCombiningEdits() was called.
