Drawing a circle and rectangle using mouse
I am really new to Qt and am still in early learning phase.
I am trying to learn through the documentations given alongwith the software.
Currently I am working in the image viewer example given with the SDK.
I want to add some functions in the program.
So, here's what I am looking for-
I opened an image. Now I want to draw circles and rectangles on the image using mouse control. So, can anyone help me and guide me through the required coding as in what do I have to do to achieve the purpose...step by step...
(using references from the same example for the instructions would be really helpful)
