Thanks.  Got it all working with actions now. Much nicer that way indeed. Onto the next challenge... 
Cheers, Frank

Hey, Sorry forgot to mention to ambiguous shortcuts. :)Also note that actions added to the widgets will also show up in the widgets context menu.http://doc.qt.io/qt-4.8/qwidget.html#addAction In general, I prefer using action where ever it is possible. They are very well support all around and give me a nice separation from the visuals. Tibold KandraiSoftware Architect & Engineer From: Frank Rueter | OHUfx [mailto:frank at ohufx.com]

Though I am getting this at the moment:
    QAction::eventFilter: Ambiguous shortcut overload: I

Will investigate further.
Thanks Tibold.

In your case IMO it should be QtCore.Qt.WindowShortcut. More here 2016-07-11 9:30 GMT+03:00 Frank Rueter | OHUfx <frank at ohufx.com>:Hi all,

below is some test code that shows the problem I'm having, where a shortcut assigned to a child widget will not be triggered once it's part of the main widget.
It works if the widget is called by itself but not when it's part of a parent widget.

I have been searching the internet for an solution but haven't had any luck.

Does anybody know what I'm doing wrong?

from PySide import QtGui, QtCore

class MainWidget(QtGui.QWidget):

        super(MainWidget, self).__init__(parent)
    def makeUI(self):
        self.layout = QtGui.QHBoxLayout()
        sw1 = SubWidget('test1')
        sw2 = SubWidget('test2')
        sw3 = SubWidget('test3')

class SubWidget(QtGui.QLabel):
    def __init__(self, text, parent=None):
        super(SubWidget, self).__init__(parent)
        self.shortcut = QtGui.QShortcut(self, context=QtCore.Qt.WidgetShortcut)

    def showInfoWidget(self, text):
        print 'showing info for', self.text()

if __name__ == '__main__':
    app = QtGui.QApplication([])
    w = MainWidget()
