Description Martin Flöser 2008-01-23 17:48:19 UTC

Version:            (using KDE 4.0.0)
Installed from:    Ubuntu Packages
OS:                Linux

I just played around with the different zoom effects and noticed a strange behaviour. To reproduce:
- activate magnifier and zoom in
- now activate another zoom effect, e.g. looking glass
- zoom in even more
- return no normal view
=> magnifier is still there and cannot be removed. You have to deactivate the effect.

The behaviour can also be reproduced with other combinations or other ordering. E.g. first looking glass than magnifier.

Idea for solution: if one of the zoom effects is reloaded or activated all other activated zoom effects should be reloaded. Or only one of the zoom effect is allowed to be selected.

JJ: EffectsHandler should get something like "void grab( QString )", "void ungrab( QString )", "bool isGrabbed( QString ) const" and KWin core would keep the list of grabbed activities (or whatever it should be called). I think there should be a refcount rathen than plain set/unset.
