I managed to have find a resolution. Instead of using `dockCloseEventTriggered`, using of `closeEvent` seems to have resolve it.
I have to write my UI create code to include something as follows: self.ui.closeEvent = self.closeEvent And this seems to be picking up in both Maya 2017 and 2018. Or as one of my co-worker is telling me that the `MayaQWidgetDockableMixin` I am using could be a custom build since my company may have rewritten certain portions to conform it to other tools. -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
