User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
Description of problem:
Mozilla does not recognize any changes to the clipboard by KDE
applications, and vice versa. Gnome & Mozilla seems to work fine.
Behaves the same when logged in KDE or Gnome.
1. Cut & Copy in Konquerer or kwrite will show up in klipper and paste
within any application (Gnome, etc.), but it will not paste within Mozilla.
2. Copy within Mozilla. Will not paste in KDE applications, and does not
show up in klipper.
3. Copy "gnome" within gedit (Gnome). Paste in Mozilla "gnome".
Copy "KDE" within kwrite. Paste in Mozilla "gnome". Paste in
Steps to Reproduce:
Copy in a KDE application. Attempt to paste in Mozilla.
Copy in Mozilla. Attempt to paste in a KDE application.
Actual Results: Changes to clipboard within Mozilla and KDE are not
recognized between the two. Gnome works with both the clipboards of KDE
Expected Results: Clipboard changes should be recognized between KDE and
Roswell + latest up2date packages as of August 13 2001.
I'm pretty sure this is fixed in recent rawhide releases.
This turned out to be an expected behavior of QT2. They never did fix this, but
it was expected to behave in a more expected fashion in QT3/KDE3 where select
will no longer reset the clipboard, only the select and middle click thing.
The whole mess is explained here.
So it will never be fixed in KDE 2.2.2, but it works reasonably well in KDE3
right now. KDE 2.2.2 users must always use select & middle-click to copy and
paste between Gnome, KDE and Mozilla without any surprises.
