python - Remove what'sThis from a dialog in pyside -

i have found quite few questions doing in c++, none doing in python/pyside. want remove '?' button

top of qdialog. know use setwindowflags(), don't know should pass arguments.

based on how can hide/delete "?" button on "title bar" of qt dialog? can this:

from pyside import qtgui, qtcore app = qtgui.qapplication([]) d = qtgui.qdialog(none, qtcore.qt.windowsystemmenuhint | qtcore.qt.windowtitlehint) d.exec_()
