Summary: View mode: mouse zoom and pan
Platform: Ubuntu Packages
AssignedTo: [hidden email] ReportedBy: [hidden email]
Version: (using KDE 4.2.0)
Installed from: Ubuntu Packages
Currently, one can click a thumbnail and go to View mode, then click the photo
in View mode to go back to thumbnails. I suggest that this behaviour be
retained but with an improvement:
When the user operates the scrollwheel over the photo in View mode, the photo
would zoom in and out according to the scroll direction. Once zoomed in (so
that there are scrollbars) then the mouse click would pan the photo. To return
to thumbnails, the user would either double click the photo or use the keyboard
The zoom/pan behaviour that I describe is how Eye of Gnome works, and it is
very intuitive and easy to operate.

I had the chance to introduce a Windows convert to digikam today. Sure enough,
she moved the mouse wheel expecting it to scroll. After learning to scroll with
the slider, she went right up and clicked the photo, expecting to be able to

This is the plan for preview widget (common to editor, Light table, and preview
mode): Code still to use QT3 transition classes. It must be ported to Qt4
model/view. All changes will be done during code conversion.
Currently, we working to others part of digiKam to convert to Model View ,as
Icon view, folder tree view, and thumbbar. when all of these will be port,
digiKam will be really a pure Qt4 application.
Porting these code to Qt4 model view take a while. They are core implementation
with full feature to test in regression. Please, you must be patient (:=)))

Can you make such behavior optionally ? I mean to give choice to reassign all
buttons. To be able to slide photos with mouse wheel, and move in zoomed frame
with left button and etc.
I hope this request suites to this wish-list. Thank you in advance.

All is possible, but i won't, because it will be a big puzzle... At least the
interface must have the same behaviors everywhere. I try to do it currently,
and it's not simple.

I didn't meant to change default buttons behavior. Only option to reassign
them. Something like "configure shortcuts" in "settings", but with possibility
to change mouse click reaction in different view (collection view, photo view,
zoom and etc).
Open a new wish, cause you can close this after implementing Dotan Cohen wish

Pan on _middle_mouse_button_? I hate that! The otherwise terrific fsviewer file
manager does that and I cannot stand it. Please, add an option for pan (when
zoomed) on left mouse button. Please!
Note that this is the intuitive behaviour expressed by most users not familiar
with Digikam: just give Digikam to a new user and see how they intuitively try
to pan with the _left_ mouse button. I've seen it literally over 20 times.

I have to agree that panning with the left button seems the most natural way.
Most image viewers I can think do that and it is the default and only behavior
for KDE's gwenview so it is kind of a standard.
Personally because of this I use digikam for most of my needs but when I need
to seriously view/preview photos I open gwenview which I feel has the most easy
controls: pan with left click, switch between fit to view and 100% with middle
click and select if the wheel will scroll between images or zoom in/out.
Another thing is laptop users. Middle click for them isn't that easy while

And i have a problem here, especially with editor canvas, where left mouse
button is used to make a selection not to pan image.
To have the same behavior, i used middle button everywhere, to be homogenous
with pan action. Do you understand ?

About Laptop, i know, i has one without external mouse. this is not a problem:
use pan icon widget from bottom/right corner of preview

For me left mouse button is not always the reference to pan. An example : Gimp
use _also_ middle mouse button to pan. Left mouse button is delegate to tools
(painting for ex).

Thanks for the clarification. I respect that you try to have consistent
shortcuts and controls' behavior throughout digikam suite.
Indeed image editors usually pan with the middle button but image viewers most
of the time use the left button.
