I am not sure if I'm using gtk or not. I'm not using Qt if you mean QtCreator. I'm just using emacs for editing, no IDE.

For example, what is it like on your os/toolkit configuration? I am using Ubuntu 14.04 and OpenCV 2.4.8. I don't know what you refer to as toolkit actually.
2016-06-27 11:25:56 -0600	asked a question	How does the call stack look like when mouse callback function is fired? The situation here specifically is that if the mouse callback takes very long to finish, and the user keeps clicking and triggering the callback, will the old, unfinished function be preempted? Or will the old one keep executing and the new callback is placed on a separate thread (or some other way)? Thanks!
