Description Tom Hall 2012-07-28 18:29:54 UTC 
I'm guessing there will be some options/preferences related to the new interaction system when it is finished, but just in case:

To me, zooming with ctrl + middle mouse drag feels backwards/inverted.

Reproducible: Always

Steps to Reproduce:
1. Hold ctrl and drag up and down with the middle mouse button.
Actual Results:  
Dragging up zooms in, dragging down zooms out. No option to invert the behaviour.

Expected Results:  
Dragging up zooms out, dragging down zooms in, but more importantly: Option to invert the behaviour if the user wishes.

As far as I can tell, the behaviour is currently hardcoded. Offering the user an option to invert the behaviour should mean that there is no need to debate which way is better (probably mostly personal preference). However, for what it's worth (even with an option, one way still has to be the default):

MyPaint's zoom works the other way round (up = out, down = in). Having canvas interaction that is very similar, but backwards, could be very annoying for those who use both programs in their workflow.

Pushed by rempt into branch 'calligra/2.8'.

This option has (intentionally) no gui...

Add InvertMiddleClickZoom=true to the kritarc file and the action is
inverted :-)
