Is it possible to trigger a function when the mouse stop moving?
For example, I have a scale, and I want to trigger a function when I still holding a button and stop dragging. I used 'ButtonRelease-1' but I had to release a mouse button to be able to trigger a function, it's not what I want.
Hope you guys can help me.
Thank you in advance.
No, you can't bind to "mouse stopped moving". However, you can bind to <B1-Motion>, and with each callback set a timer to run in the future. If the mouse hasn't moved within that time the function will be called. Within that function you could use event_generate to generate a custom <<MouseStopped>> event. If the mouse moves before the timer expires, reset the timer. 
You get the exactly the same effect as if you bound to the mouse not moving.
