Changed:
U trunk/dabo/ui/uiwx/__init__.py
U trunk/dabo/ui/uiwx/dMenuItem.py
U trunk/dabo/ui/uiwx/dPemMixin.py
Log:
Added the '_delayedEventBindings' attribute to dPemMixin. This was needed for
menus created by MenuDesigner mnxml files for Actions that involve the form.
Turns out that the menu's OnHit is processed before the reference to
'self.Form' has been set, so it was impossible to set a menu item's action to
something like 'self.Form.menuHandler()'. These changes simply delay the
binding until after the menu item has been fully created, allowing the
framework to properly resolve the binding.
