I am working on an application using a Rasberry PI (linux). It is working well. But I am working on a 5" touch screen that is 800x600. The problem is that standards sizes of everything is way too small. For example I have an alert window that has a combobox and cancel/save/ buttons. The default sizes of the buttons and the comboboxes are too small for my large fingers.
I made the window larger by doing this getTopLevelWindow(1)->setSize(600,400); on the AlertWindow. But the items within are still too small.
Is there a way to scale everything larger ?
