How to remove title but with frame border?

[shaoli.xie]

hello, friends..
i wanna to put my widget on the title bar with qt

on window platform,
i use Qt::FrameLessWindowHint to hide the caption, and use WM_NCHITTEST to deal with move and resize.
but without borders, i move the window to screen edge, window can't maximum or restore by system.......

then , i tried to use SetWindowLong() to make border back...it works, but too ugly....code and the widget..
at last, i make client area over title bar with WM_NCCALCSIZE message, it works, but have many bugs....then, i changes lots of QtGui's codes to make it deal with WM_NCCALCSIZE... update frameStruct and client Rect etc..

but, on linux platform, i can't find any help from XLib Api... can i create canvas intead of window?
or use Qt::FrameLessWindowHint, and try to solver Scrren Edge problem?

thanks for any reply...

so poor my english....

Hmm I don't quite understand what you mean by 'put my widget on the title bar with qt'.

Do you want to get rid of the title bar of a widget (top part of a widget with title, max/min/close buttons)?
Or do you want to get rid of entry on the window task bar (on the bottom of the screen when icon of your app appears)?

Whatever you want, I can bet that there's no need to go native, this way you make your code not-portable.
Qt should suffice.

And what 'screen edge problem' you mean?

If you have a frameless window and want to be able to maximize / minimize / close it by the system you need to add some more window flags

FramelessWindow::FramelessWindow()
: QWidget(0, Qt::WindowFlags(Qt::FramelessWindowHint | Qt::WindowMinMaxButtonsHint | Qt::WindowSystemMenuHint))

FramelessWindow::FramelessWindow()
: QWidget(0, Qt::WindowFlags(Qt::FramelessWindowHint | Qt::WindowMinMaxButtonsHint | Qt::WindowSystemMenuHint))

To copy to clipboard, switch view to plain text mode 

If you want to be able to grab the edges of your window and resize it you will have to implement this yourself or use a utility like Frameless Window Helper
