How to get zoom factor in UI handling?

Hello,

Is there any way to get the current level of zoom in a doClick handle?

In fact i'd like to compute the size of the window in which the video is displayed.

I tried by using source_to_frame but didn't succeed.

Thx in advance!

use event_extraP->cbs.frame_to_source() to check the gotten coordinates of (100, 0).

then then divide the gotten X result by 100, and you have the scale factor.
