# pylint: disable=line-too-long
# This is based on a simplified version of http://stackoverflow.com/questions/14034209/convert-string-representation-of-keycode-to-qtkey-or-any-int-and-back. I added code to handle the case in which the resulting key contains a modifier (for example, Shift+Home). When I execute QTest.keyClick(widget, keyWithModifier), I get the error "ASSERT: "false" in file .\qasciikey.cpp, line 495". To fix this, the following code splits the key into a key and its modifier.
# Bitmask for all modifier keys.
modifierMask = enum_as_int(Qt.KeyboardModifierMask)
ks = QKeySequence(keySequence)
# For now, we don't handle a QKeySequence("Ctrl") or any other modified by itself.
assert ks.count() > 0
for _, key in enumerate(ks):
key = key_code(key)
modifiers = Qt.KeyboardModifiers((key & modifierMask) | enum_as_int(extraModifiers))
key = key & ~modifierMask
QTest.keyClick(widget_, Qt.Key(key), modifiers, 10)
