Qt::FramelessWindowHint

[L.Marvell]

In Qt4.0.0 & Qt4.0.1 I used flag Qt::FramelessWindowHint to get off button on taskbar. But now in 4.1.0 & 4.1.1 it doesn't work. Can anyone explain what happened and what to do?

Qt4.1.1 with MinGW on WinXP Pro.

Keep trying to find out but without any result yet

Can anybody help me with this?

could you post some code to see how you set this flag?

Look at this thread that I posted where I use it succesfully:

In constructor of my class:

setWindowFlags(Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint);

setWindowFlags(Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint);

what do you mean get off button on taskbar....be more clear.

also please stick the code as much as possible so that we can relate to your problem...your function declaration will not help us understand your problem!

I mean that I don't need button of my application on windows' taskbar. In earlier versions of Qt the same string of code setWindowFlags(Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint); worked perfect: app was without titlebar and without that button on taskbar. Now the button appears but it doesn't have context menu.
See attached screenshot.

AFAIK Qt::FramelessWindowHint is not useful for what you want to achieve. It only creates a window without the buttons (maximize, minimize and close) and the border around the window....

But worked in Qt < 4.1.x. Anyway, what to do now? Who knows?

Have you tried to set some other window flags? Qt::Popup, Qt::SplashScreen,...

I've tried all of flags but without any good result

Ok, it seems Qt::Tool creates window without taskbar button, but there is another problem. When clicking on "Ok" or "Cancel" of any dialog that belongs to app - dialog closes but main window closes too
If anybody wish he can download sources at http://www.badongo.com/file/596445 and look in. Window flags set in clockwindow.cpp at 27 row. Try to play with it.

Have you tried to open the dialogs as top level (with no parent)?

Nope but will try. Thanks for advice!

[L.Marvell]

Boom... Main window closes even when pressing "Ok" in standard About Qt dialog

[L.Marvell]

It seems it doesn't matter has dialog parent or not. Main window closes anyway. It's pitty

[L.Marvell]

Well all Ok. Works with setQuitOnLastWindowClosed(false).
