A stopgap patch to scim-bridge-qt
Fixed in scim-bridge-0_4_15-7. Thanks. *** This bug has been marked as a duplicate of bug 464397 *** |
Created attachment 315960 [details] Stack trace of the text deletion event. Description of problem: On a KDE4.1 system with Qt SCIM bridge installed and configured, selecting a region of text in Kate or KWrite and then switching to another application and back causes the text to be deleted. Version-Release number of selected component (if applicable): Fedora 9 + all updates + currently pending KDE4.1 update How reproducible: On an appropriately configured system, 100% predictable results. Additional info: I debugged the problem to produce a stack trace, and made a patch for scim-bridge-qt that fixes it for me. Note that this is the first time I ever had to fix anything in Qt/SCIM, so my analysis might be wrong: The bug is caused by preedit string update events that were sent by scim-bridge during the focus change sequence. Problems: 1) QInputContext::setFocusWidget() is called before focus_out() 2) Preedit string hide event is sent even if it wasn't displayed. As a result, when the focus is switched in, the _target_ Kate widget receives a preedit event, and trashes its selection.
