Detailed Description¶
QUndoView
is a QListView
which displays the list of commands pushed on an undo stack. The most recently executed command is always selected. Selecting a different command results in a call to setIndex()
, rolling the state of the document backwards or forward to the new command.
The stack can be set explicitly with setStack()
. Alternatively, a QUndoGroup
object can be set with setGroup()
. The view will then update itself automatically whenever the active stack of the group changes.
