qdialog and taskbar

[Michael_Levin]

hello!
i have some question that as i see appears many times, but nevertheless i can't find the solution for me.

i have some widget, and the button in it, and when i press this button i want to appear some other widget, frameless and not
showing in the taskbar.

i can achieve two results - frameless or 'taskbarless' =)

1 -frameless - everything is ok, but it of course appears in the taskbar

(code in PyQt4)

self.add_new_light_widget = QWidget()
self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.FramelessWindowHint))

self.add_new_light_widget = QWidget()
self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.FramelessWindowHint))

To copy to clipboard, switch view to plain text mode 

2 - 'taskbarless' - now it is the dialog with the parent of main widget, so it doesbn't appears in the taskbar

self.add_new_light_widget = QDialog(self)
self.add_new_light_widget.setWindowTitle("About")
self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.Dialog))

self.add_new_light_widget = QDialog(self)
self.add_new_light_widget.setWindowTitle("About")
self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.Dialog))

To copy to clipboard, switch view to plain text mode 

but if i use

self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.CustomizeWindowHint))

self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.CustomizeWindowHint))

To copy to clipboard, switch view to plain text mode 

(or frameless hint) my new widget will not show!

please help me - where am i wrong?
thank you!

I don't use pyQt, but maybe this will help You. In Qt I do:

infoDialog* info = new infoDialog( this ); //parent here is important, that way qdialog don't show on task-bar
    info->setWindowFlags( Qt::Dialog | Qt::WindowCloseButtonHint );//reset flags, to remove [?] icon, only [x] icon on window

infoDialog* info = new infoDialog( this ); //parent here is important, that way qdialog don't show on task-bar
    info->setWindowFlags( Qt::Dialog | Qt::WindowCloseButtonHint );//reset flags, to remove [?] icon, only [x] icon on window

To copy to clipboard, switch view to plain text mode

thank you)
yes, parenting dialog helps avoiding the taskbar appearance, but in this case the title line with the close button is shown - and i want frameless widget =)
the solution i found is

self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.Tool)|Qt.WindowFlags(Qt.SplashScreen))

self.add_new_light_widget.setWindowFlags(Qt.WindowFlags(Qt.Tool)|Qt.WindowFlags(Qt.SplashScreen))

To copy to clipboard, switch view to plain text mode
