Unsolved QtCore.Qt.FramelessWindowHint not working on my Windows machine ...

[Goffer]

Hi everybody !

I ve wrote some code on a linux machine that runs fine but when I try to run it on my windows machine then it doesn't work as expected anymore.
The Frameless flag closes my QMainWindow ...

"""."""
from PySide import QtCore, QtGui


class TabBar(QtGui.QTabBar):

    """Allow to drag a tab anywhere on the screen."""

    def __init__(self):
        """Initialize the class."""
        super(TabBar, self).__init__()
    # end def __init__

    def mousePressEvent(self, event):
        """."""
        index = self.tabAt(event.pos())
        self.tabContent = self.parent().widget(index)

        self.tabContent.setParent(None)
        self.tabContent.show()
        self.tabContent.move(QtGui.QCursor().pos())

        print self.tabContent.parent()
        self.tabContent.parent().setWindowFlags(QtCore.Qt.FramelessWindowHint)
        super(TabBar, self).mousePressEvent(event)
    # end def mousePressEvent

    def mouseMoveEvent(self, event):
        """."""
        print 'move'
        self.wid.tabContent(QtGui.QCursor().pos())
    # end def mouseMoveEvent

    def mouseReleaseEvent(self, event):
        """."""
        print 'release'
    # end def mouseReleaseEvent
# end class TabBar

Why is it not working on my windows machine ??

Thx

Okay, apparently I have to set Frameless BEFORE showing the window ...
