Description Daniel 2016-11-13 06:10:14 UTC

At the moment, in order to zoom in / zoom out of an image, I have to hold down the Ctrl key and then use the scroll wheel to zoom in and out, rather than the much more familiar action of just scrolling and zooming in / out (no holding down Ctrl key).

Please make it so that scrolling the mouse wheel will zoom in and out.

Thank you.

Using version: 16.08.3 (Frameworks 5.27.0, Qt 5.7.0)

How is this still unconfirmed?

Still happens in the latest version, 16.12.3.

The change to remove the ctrl key requirement is trivial, but it would necessitate a few other changes to prevent conflicts and unwanted behavior:

- With a mouse+wheel, when the image is zoomed in, a scroll is already used to pan up and down; that behavior would need to be re-assigned to something else, or just gotten rid of, since you more easily can drag to pan anyway

- For laptop users who scroll with a two-finger up-and-down scroll gesture, the very similar two-finger drag gesture is already bound to pan&zoom. This would either need to be removed, or else the two-finger scroll behavior would have to not apply to touchpads, and zooming would use a pinch gesture instead: https://bugs.kde.org/show_bug.cgi?id=378021
