Treeviewer performance problem [message #548961]

Hi,

hopefully I am at the right place with "my" thread - eventually it's my first one Rolling Eyes

I am using my firsttime SWT in a project and directly run into trouble. Actually, everything is working fine, except the performance of the treeviewer. A refresh from ~ 1000 entries to ~ 50 entries needs round about 15 seconds.

If I make the same refreshing and press two times alt+tab, the refreshing needs exactly this time (switch to another "window" and back) Confused

Does anybody had the same problem and fixed it?

Would be happy for answers.

Thx

mark

Hi All,

the problem was, that the tree redraws with every new entry.

To solve the problem, set the redraw of the tree to false, refresh and set the redraw true.

=> filteredTree.getViewer().getControl().setRedraw(false/true);
