Paint Windows Frames

[Iskander]

aamer4yu, I tried to use qskinobject, but when I enable skins in example, widgets start blinking.

I almost finished emulation of moving and resizig, but when Qt::SplashScreen flag, there is no application on a task bar. How to remove system windows decorations, and save precense on a task bar?

You can inherit from QDialog and overload the paint method.

Of course I inherits from QWidget and all my windows inherts from my "skinned widget". But in paint method it is impossible to draw system windows borders.

Didn't I tell you that like... 7 posts ago? They are called "system borders" for a reason. All you can do is disable them by passing Qt::FramelessWindowHint hint to your widget.

yes, my previos post was answer for NoRulez.

ok

Yes, I've done it in 0 post. How to stay on a task bar, while setting the flag?

You can't. At least not without diving into native API although I think in this particular case it wouldn't help.

So should I do something like this?

#if defined(Q_WS_WIN)
  .... 
#endif
 
#if defined(Q_WS_X11)
  .... 
#endif

#if defined(Q_WS_WIN)
  .... 
#endif

#if defined(Q_WS_X11)
  .... 
#endif

sadly.

And, as I understand, under linux behaviour depends from current DE settings...

May be it is possible to use QDesktopServices, do you know?

Well, I think about creating a widget out of display region, and in focusInEvent make my "skinned" widget focused, but I think, it's too dirty hack...

[wysota]

What would desktop services have to do with that? What is exactly that you want to obtain?

[Iskander]

Sorry for my english.

I want to use my own systems borders(1). So I set Qt::FramelessWindowHint flag.
But there is no my apllication on the task panel in that way.(2)
I want something like winamp - but skin systems does not requiered.


I read QDesktopServices docs, and not found anything, relative to my problem, it serves for desctop enviroment, not for task bar, so sorry for my question

[wysota]

Try searching for a solution in WinAPI docs but I doubt you will be able to get the taskbar entry back after disabling system borders. You can try something else though... Don't disable the borders but instead mask them out using QWidget::setMask(). You should not lose the taskbar entry then but the borders wouldn't be visible and you could provide your own ones inside the client area.

wysota, thank you! setMask(rect()) works fine!

Just note that things such as maximizing the window will probably work incorrectly.
