Description John Schroeder 2013-08-13 05:41:00 UTC

When the document is updated, kate's symbol list viewer plugin flickers and doesn't indicate the current location unless the cursor position is changed.

Reproducible: Always

Steps to Reproduce:
1. Enable symbol list viewer
2. Open/create file with some content that will populate symbol list viewer
3. Make changes to the document and note symbol list flickering
4. This is especially distracting in tree view
Actual Results:  
Symbol list flickers in a very distracting manner and doesn't correctly indicated the current cursor position unless it is changed.

Expected Results:  
Symbol list should not flicker and always indicate the current cursor position.

I have attached a patch that fixes the issue by calling updateCurrTreeItem() at the end of slotRefreshSymbol() and there is a link to youtube demonstrating the flickering in the details.
