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?
