[QGIS-Developer] Testing a ComboBox with a QCompleter using QTest

Hi Larry,
Thank you so much for that! It all works as you describe, except that my
QGIS doesn't show that completer where one would expect it (under the
combobox), but rather at position 0,0 of the widget it is in. So that's
odd. The mouse pointer is moved to the middle of the displaced completer
widget, so your code works fine.
The other thing that doesn't work as expected, is that the mouse click
doesn't transfer the entry to the combobox.
When I don't let the script do the mouseclick and I do it myself, it also
doesn't work. (not executing the last mouseclick of your script and then
doing it manually)
When I do arrow up or page up and then enter, it also doesn't work.
When I start the whole test manually, the popup appears where one would
expect it and it's possible to type in the combobox's lineEdit and then
mouseclick to select the value from the completer.
Normal:

This is what happens when run from the script:

So that's weird, as if it didn't know what combobox it belongs to. The
mousepointer is at the correct position though. Clicking it manually has no
effect either.
