Hi,
I am now trying to create a level editor for my game so a txt file can be generatered and used to hold vertex data amonst other stuff. I have decided that inorder to remain cross platform independant, i will write the editor in C++ with OpenGL. My problem mainly lies with the lack of knowledge of graphics programming in C++.
What i would like to know is how to set up a window where the user can draw shapes but more so how to allow the user to resize the shapes with their mouse. I will be most grateful for any help.
