Description Julien Narboux 2006-09-19 08:53:45 UTC

Version:            (using KDE KDE 3.4.2)

I would be great if when the mouse pointer is over a thumbnail two buttons appear in the corner of the thumbnail. The left one perfoms a 270° lossless rotation and the right one a 90° lossless rotation.
IMHO It would be more intuitive than the right click menu action (and it saves a click).

This is the way it is done in several other photo managment software.

Comment 1 Mikolaj Machowski 2006-09-19 15:42:03 UTC

Second that. BTW - could we get rid of 90, 270 deg rotation? Everywhere
is Left, Right rotation...

Comment 2 Andi Clemens 2008-12-04 20:55:47 UTC

Gilles, Marcel,

this can be done with the upcoming new iconview, based on model-view concept and purely Qt4 wigets?
This could work like in gwenview...

Marcel,

I currently study new class named ImageRotateOverlay to implement this feature. Fine for you ?

Comment 6 Marcel Wiesweg 2009-05-31 17:20:56 UTC

Yes.
Just look at ImageSelectionOverlay. Derive a class from HoverButtonDelegateOverlay and create one overlay object per button.

Comment 7 caulier.gilles 2009-05-31 18:42:34 UTC

ok. fine. i will do it.
