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

[Jo]

Hi,

I'm really stuck on this.

I'm trying to test a combobox with a completer:

When I do these manually, they work:

        cb = self.form.dockwidget.widget['sc_510_002']
        QTest.keyClicks(cb, '9000')
        QTest.qWait(1000)
        QTest.keyClick(cb, Qt.Key_PageUp, Qt.NoModifier, 500)
        QTest.keyClick(cb, Qt.Key_Enter, Qt.NoModifier, 500)

When I want to simulate them with the above commands, all I see is the
popup.

I also tried the following:

        cb = self.form.dockwidget.widget['sc_510_002']
        QTest.keyClicks(cb, '9000')
        lv = cb.findChild(QListView)
        QTest.qWait(1000)
        QTest.mouseClick(lv.viewport(), Qt.LeftButton, 0,
lv.visualRect).center())

Based on what I found here:

and here:

I was glad I managed to translate it from C, but no joy.
