Main Window resizing

tesmai4

I developed my application interface using QT. I have different QWidget in my interface.
How can I set it fit in different screen sizes?

With layouts "http://qt-project.org/doc/qt-4.8/qlayout.html":http://qt-project.org/doc/qt-4.8/qlayout.html

May be just use showMaximized() the main widget (or MainWindow), it will fit to the screen (any screen size)

Thanks Santosh for your reply.
I have two screen one in landscape mode and other in portrait mode.
showMaximized() works for landscape screen, however, layout is destroyed on the portrait screen.
How can I tackle these varying size and orientation screen issues?

Santosh Reddy

It is not possible to have same layout in both, in most cases applications with such requirements end up implementing different layout for landscape, and a different layout for portrait.

Thanks for reply. I appreciate it.

can you elaborate a bit on this point? How will I detect different screen sizes and how will my app switch from one layout to other and vice verse?

I have already grouped my widgets into different horizontal and vertical layout. How will I add different layout to my main window?

For this kind of requirement we have QML, since just repositioning widgets doesn't give you a good result.

Either way, what you can do to detect orientation is related to which platform we are talking about, but a simple way is to use QDesktopWidget (via the static method QApplication::desktop()).
