On the top of tree of 3.7 I see that when I switch from one Java source file to the other, focus leaves the sample view, so when the mouse goes over the link it remains an arrow. The cursor is only supposed to change when the view is first responder, and that makes sense to me from the platform's perspective. My hunch is that NSTextView uses an NSTrackingArea to implement the cursor updating. However, in Control#updateCursorRects we call removeTrackingArea when the widget is disabled, and I can see that the link is being disabled when we move from one tab to another. That's bad because we don't own any of the tracking areas the view may have created. Cocoa only sends mouseMoved messages to tracking areas or the first responder, so I think the best way to handle it is to force an update with mouseMove if we send SWT.MouseMove and the view isn't first responder. NSResponder's mouseMoved: might be called twice, but I haven't seen any harm yet in doing so. Fixed > 20110118. |
Created attachment 178331 [details] Plugin to reproduce The problem looks weird to me. I have a view that displays a link. If my application is launched with the view already present in the workbench, then the hand cursor does not appear on the link after the couple of editors are switched. Steps to reproduce : 1) Please find the attached plug-in - self host the eclipse using this view. 2) Make sure the view is present when the eclipse is launched (next time). 3) Hand cursor appears on the link at this moment. 4) Create 2 Java files - switch between them. 5) The hand cursor does not appear on the links :( Note: The problem goes away if the view is closed and restarted. Also, the problem occurs only when the view is loaded along with the workbench. On Cocoa, we set the offsets required for displaying the hand cursor to the platform. This is not clear why the hand cursor is not appearing after the editors are switched.
