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.
