Hi Paul,

sorry to make you repeat yourself, but I was already doing all that, so I was at a bit of a loss. However, your reply made me look a bit harder: I was parenting the widget to Nuke's main window in it's constructor, which yielded very unexpected results (bad practice anyway I guess). For some reason when passing the parent widget as an argument when creating an instance of the widget it works as expected.
Thanks!

Cheers,
frank

You need 3 things:
1. Inherit your widget from QWidget/QMainWindow/QDialog
2. Parent widget to main nuke window. Use this function

def getMainWindow():
    for widget in qApp.topLevelWidgets():
if widget.metaObject().className() == 'Foundry::UI::DockMainWindow':
            return widget

3. If you inherited from QWidget you need to set flag Qt.Tool or Qt.Window.
Its all. No need to register nuke panel if you need float window.

        If I register it as a panel I wouldn't have the stay-on-top
        problem, but
        that seems to lose the ability to scale the wrapping widget so
        it fits
        the custom widget, resulting in the user always having to
        resize the window.
        At the moment I am just opening it as a non-modal panel via
        show().

        Setting parent=QtGui.QApplication.activeWindow() crashes Nuke
        when the
        panel's show() method is called.
        Setting no parent leaves me with the original problem.

        Ideally I'd wrap it as a nuke panel via
        nukescripts.registerWidgetAsPanel(create=True), then call
        show() on the
        returned object. But as mentioned above, this creates a parent
        widget
        that does not scale according to the widget it's wrapping.
