Game Programming Using Qt

Designing GUIs

So far, we have coded all the user interfaces manually by writing C++ code that instantiates widgets, arranges them in layouts, and connects signals to slots. It is not that hard for simple widgets, but becomes tedious and time-consuming when the UI becomes more and more complex. Fortunately, Qt provides tools to do all this in a more pleasant way. Instead of writing C++ code, we can create forms using a graphical tool by dragging and dropping widgets on a canvas, applying layouts to them, and even establishing signal-slot connections using the point-and-click technique. Later during the compilation, such forms will get converted into C++ code for us and will be ready for applying onto a widget.

The tool is called Qt Designer and ...
