[PyQt] coloring a QDialog

[TP]

Hi everybody,

To color a QDialog (for example), I can do:

from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys
app = QApplication( sys.argv )
dialog = QDialog( )
dialog.palette().background().setColor(Qt.blue) # @
dialog.show()
app.exec_()

But if I replace the line "@" by:

dialog.setForegroundRole( QPalette().Dark )

it seems it does not work: the color is the same with and without this line.

What is the problem?

Thanks

Julien
