I am in process of making an application which will run on almost every devices which supports Qt. But I am curious about the GUI. In Qt Creator I had designed a form which was looking fine but when I saw that in emulator then it was going out of screen area, fonts were big etc etc.
So I want to ask what are the ways to target multiple devices. Some devices come with Landscape and portrait Orientation, some are touch screen, different resolutions etc etc so there are several problems.
What are the Best practices for these problems?
