[Qt-interest] QMainWindow size...

[OS Prog]

Hi David,
Thanks for the reply.

The application is intended to run on embedded in fullscreen -
mainWindow.showMaximized();

Under windows I have defined
#define SCREEN_WIDTH 640
#define SCREEN_HEIGHT 480

in order to develop/debug it.

The problem is that at the time of mainWindow creation (MainWindow
constructor) the window sizes are not what I want to be (the
mainWindow->width() and mainWindow->height() returns a value different from
that I want).
In the mainWindow constructor I initialize QAnimationFramework and a number
of widget, icons ... and I'd like to position them properly on the screen,
that's why I want the size to be set before the mainWindow is created and to
be constant(unchanged).

If I use the defines instead of width() and height() it works fine, but the
application should run on different screens (embedded target) maximized, so
I cannot use constant sizes.

Regards,
Nikolay
