How setStylesheet ocuppy resolution 1366 by 254 only

[houmingc]

My picture resolution is 1366 by 254.
Would like setStyleSheet to occupy 1366 by 254 and mainwindow size is 1366 by 1016.

MainWindow w;
w.setStyleSheet("background-image:url(:/file/left.png)");
w.setFixedSize(1366,1016);
//254 x 4

I'm not sure I understand you correctly but do you mean you don't want the image to repeat? If so then set the repeat mode:

w.setStyleSheet("background-image:url(:/file/left.png); background-repeat: no-repeat");

Chris thanks

want setStyleSheet to occupy top quarter of the mainWindow.
MainWindow size is 1366 by 1016

So... have you tried my suggestion? It should do what you want.

[houmingc]

yes i have,
w.setStyleSheet("background-image:url(:/file/left.png); background-repeat: no-repeat");

It only fills up PC monitor width, thus i add setFixedWidth to set the width i want
w.setFixedWidth(1366);

On my laptop it work perfectly, but when i cross-compile and test it on the ARM target.
The mainwindow is expanded over the whole screen. Is there any workaround?
