Has anybody managed to get the undo to work in Hiero?
It works fine when running the example in the script editor, but once
the undo block is triggered from a QAction it doesn't seem to register
at all.
Below is some example code to show what I'm doing. The custom dialog
drives poster frames in the bin while it's open.
Any ideas how to get this to work?
Cheers,
frank
class DoCustomStuff(QtGui.QAction):
def __init__(self):
QtGui.QAction.__init__(self, "Do Custom Stuff", None)
self._selection = None
self.triggered.connect(self.doStuff)
hiero.core.events.registerInterest("kShowContextMenu/kBin",
self.eventHandler)
def eventHandler(self, event):
view = event.sender
event.menu.addAction(self)
def doStuff(self):
view = hiero.ui.activeView()
selectedBinItems = view.selection()
selectedClipItems = [(item.activeItem() if
hasattr(item,'activeItem') else item) for item in selectedBinItems]
project = selectedClipItems[0].project()
project.beginUndo('franks stuff') # THIS DOES NOT WORK
dialog = CustomDialog(selectedClipItems)
dialog.exec_() # poster frames are changed interactively while
the custom dialog is up.
project.endUndo() # THIS DOES NOT WORK
