KAction::setIconSet

[Peter Hedlund]

Hi All,

I tried this in kde-devel, but didn't really get an answer. I hope it's OK to 
post here. I try to generate icons for some actions in code. The icon 
represents a character that can be configured by the user. Thus the icon 
needs to be recreated from time to time. The code below works, but there are 
a couple of problems:

1. In a toolbar the icon size will always be 22, I guess that's the default. 
If I change size using the toolbar context menu the displayed icon size isn't 
changed.

2. The KEditToolbar dialog will always use the icon size I create in code (32 
in the example below).

How can I get around these problems? I'm running KDE cvs from about a week 
ago.

Thanks,
Peter
