when you have an "editable" QComboBox and start typing, the events/letters seem to be passed on to Softimage.
This results in keyboard shortcuts being performed in Softimage instead of text being written in the QComboBox...
==== code to reproduce (just run from the script editor) ===========
from PyQt4 import QtGui, QtCore
import sip
si = Application
sianchor = sip.wrapinstance(long(si.getQtSoftimageAnchor()), QtGui.QWidget)
dialog = QtGui.QMainWindow(sianchor)
uiComboBox = QtGui.QComboBox(parent=dialog)
uiComboBox.setFocusPolicy(QtCore.Qt.StrongFocus)
uiComboBox.setEditable(True)
dialog.show()
