Frustrated trying to get maximized window.

[Doug Broadwell]

Windows, Qt 4.2.3.

I've researched through the threads, I've tried to use showFullScreen(), showMaximized(), and setWindowState( windowState() ^ Qt:: WindowFullScreen) - both in my main() and in my QMainWindow() derived object constructor.

I get a 'Flash' of full screen and then back to the small window. How does one get an application to start up full screen?

Thanks

There must be some prob with the code, check again.
Also might be that some other application is intervening.

Hi,

I had this problem time ago but I don't know what it caused It had to do with my used widgets and their arrangement in layouts. After rearranging in a different layout (with the same appearance) the showMaximized worked.

So if your layout is not to complicated try to rearrange. May this help, or not

I found the problem. My code was:

mw = new QMainWindow;
sa = new QScrollArea;
sa->setWidget( mw );
sa->show();
mw->showMaximized();


When I maximized the QScrollArea instead of the QMainWindow all was well with the world; also putting the show() after the showMaximized() resulted in cleaner screen painting.

mw = new QMainWindow;
sa = new QScrollArea;
sa->setWidget( mw );
sa->showMaximized();
sa->show();


Thanks for the help.

Why would you want to put QMainWindow inside a QScrollArea
May be theres some better way
