Change work area OS

[high_flyer]

do you mean you want to change how other programs maximize their windows?
Did I get you right?

[pakulo]

yes

for example if set task bar (panel where Start button, clock e.c.) in the right of the screen, all programs will be have width = screenWidth - widthTaskBar automatically

[high_flyer]

this is window manager specific (if at all possible).
This is not included in Qt functionality.

[pakulo]

it is a pity, because i see this func in many programs

[high_flyer]

I have never seen it - can you give some examples?

[pakulo]

I can try to find english program
But if you know russian you can see Agent mail.ru
http://agent.mail.ru/
Press button "Загрузить сейчас!"
I need more time to find in english something

Which was my point - this is an exositc thing (so not so "many programs"), and as I said, it taps directly into the window manager.

I use only russian programs, thats why i need time to find it in english...

It is impossible to write what i want in QT, for example only for Window OS

Thats no problem - other russian progams are also ok.

You can do this as part of a Qt application of course - but the functionality is not offered by Qt ite slef, since its window manager specific, and Qt is cross platform, which meas, it implements the most used aspects on all major platforms.
Any window manager or OS specifics you will have to do your self, or use 3rd party code.

In Qt i can get the size of work area. May be it is not difficult to set my own work area size?
May be somebody know where i can find some information about it and write own module?

[high_flyer]

the problem is that you want to influence other programs behaviour.
No program can do that directly.
The only way to do that is for your program to tell the window manager what the new rules are.

Yes, and these programs are directly calling Win32 to do this. You will need to do the same, and if you want the app to be crossplatform, do the equivalent under X11 and Aqua as well.

Thanks for all...
