Newbie needs advice

Hi all,

What kind of Main Window should I use?

I want a main window where I can draw a line by free hand, then add attributes to that line (attributes to be stored).

If anyone can point me to a main window code that I should use I would appreciate it. I want to look at that code, understand that code, and build upon that code.

Eventually I want to build the below but I need a good starting point to understand what is going on, so I am looking for a Main Window on where I should start.

Thanks in advance

I would subclass QMainwindow and have QGraphicsView as the central widget.

Sounds good!

Can you direct me to some already developed code that uses both QMainwindow as a subclass and QGraphicsView as the central widget so I can study it and learn from it?

Thanks in advance!

See the Ported Canvas example in the Qt Demos. It is in the Graphics View section. Also there are several other examples involving QGraphicsView/QGraphicsScene.

You should also read the Graphics View Framework, in Assistant.

Regards.
