[GTK4] Button click coordinates are incorrect for some cases [EBZ#546493] ------------------------------------------------------------------------- Key: ERT-725 URL: https://issues.jboss.org/browse/ERT-725 Project: Eclipse Release Train Issue Type: Task Components: Platform Reporter: Friendly Jira Robot Assignee: Eric Williams Priority: Major Labels: SWT, bzira Snippet3, for example, doesn't work as expected on GTK4. This is likely because the coordinates in GTK4 are all parent-relative, whereas in GTK3 they were not. Furthermore Table/Tree internals have changed, and the header buttons are part of the GtkTreeview's surface now.
