Windows without title bar but with border

[A Former User]

I have exactly the same problem and I know that it is solvable (QDockWidget does it successfully).
I haven't found an easy solution in the Qt Source. Does anybody know how QDockWidget does it?

Hi holy,

AFAIK QDockWidget is not a top levbel widget, which means, everything is done by hand :-)
For top level widgets, this is done by the windowinmg system (in the case of the OP, QWS).

Thank you for your reply. I am mainly interested in linux desktops.

If i create a QDockWidget without a parent, it is a top-level widget and still it does not have a system title bar. The flags it has are:

@
(Qt::Window | Qt::WindowTitleHint | Qt::WindowSystemMenuHint | Qt::WindowMinimizeButtonHint | Qt::WindowMaximizeButtonHint | Qt::WindowCloseButtonHint)
@

So how does it get no title bar even though it has the Qt::WindowTitleHint flag set?

I would propose, you look at the source code.
perhaps (as it it typically not a top level widget) perhaps, these flags have a special handling in this class?

I want to know whether I can do that in Qt quick project?

[giesbert]

if you have a main app and a QDeclarativeView, you can do stuff in C++.

-In that case, let me just move it for you.-
-In the future, you can just use the "report" link next to your post and request an admin moves it to the correct subforum. -
update:
I decided to split off the topic, because the " other part":http://developer.qt.nokia.com/forums/viewthread/8140/ was on mobile & embedded (moved that part back there). Thanks for searching the forum before just posting your question, but sometimes it is better to just link to it instead of reviving an old topic.
