PyQt: Always on top

This is on PyQt4, Linux and Python 2.5

Can I make PyQt set my window "always on top" over other applications?

For example, in GTK i use the property: Modal.

Now, in PyQt I am using a QWidget, but, I can't fi开发者_如何学Gond a way to do that.

Any ideas??

Pass the QMainWindow the WindowStaysOnTopHint window flag (or use setWindowFlags).

As in the name, this is a hint to the windowing manager (not a hard guarantee).

Simplest possible example:

import sys
from PyQt4 import QtGui, QtCore

class mymainwindow(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self, None, QtCore.Qt.WindowStaysOnTopHint)

app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()

setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)

setwindowaFlags is a method that can call it from form object and just take one parameter is a constant QtCore.Qt.WindowStaysOnTopHint that refer to make your form Stays On Top
