[GTK3] Endless calls to Tree.rendererGetPreferredWidthProc after clicking on editable PropertySheetPage tree cell [EBZ#544140] ------------------------------------------------------------------------------------------------------------------------------ Key: ERT-702 URL: https://issues.jboss.org/browse/ERT-702 Project: Eclipse Release Train Issue Type: Task Components: Platform Reporter: Friendly Jira Robot Assignee: Eric Williams Priority: Major Labels: SWT, bzira See https://bugs.eclipse.org/bugs/show_bug.cgi?id=535978#c14 > We are trying a 4.11 integration build as a base for our product and our > ARTs ran into a hang.

Or should I re-open this one? So far no luck in reproducing this outside of our product. We have a GEF based view, with some drawn canvas on the left and a property page on the right. Clicking on an editable cell in the property page opens an editor. From that point on we see endless calls to Tree.rendererGetPreferredWidthProc. This results in an endless wait in a few of our ARTs, which wait on display events and jobs after clicking on a cell in order to edit it.
