If you detach a an editor window from Eclipse and snap it to the edge of the screen using Windows+Right or Windows+Left, then minimize eclipse, the size and shape of the detached window will be forgotten when you restore again. This is true in Windows 8 and Windows 10.
Reproduced in Eclipse Platform Version: Oxygen (4.7) Build id: I20160803-2000 OS: Windows 10, v.10.0, x86_64 / win32
Note: this does not happen in Linux (Ubuntu)
After a debug session, I verified that WBWRenderer#hookControllerLogic(MUIElement me) defines a ContolListener that handles the #controlResized() and #controlMoved() for the detached windows. I suggest looking into : - WBWRenderer#hookControllerLogic() - WBWRenderer#subscribeTopicWindowChanged()
After more debugging, I observed a detail, that could explain why the detached window forgets the size. Looking at WBWRenderer#hookControllerLogic(), observe when the ControlListener is added, and add a log, to see when the #controlResized(.) or #controlMoved(.) are called. Practically, when you minimize by clicking the minimize button on the Main IDE window, the ControlListener, registered to track #controlResized(.) and #controlMoved(.), is called only for the main Ide Window, but not for the Detached one. Please, see it live in this 2 min. video: https://www.youtube.com/watch?v=W46tLxSx-aU I think this could be an SWT issue, as the SWTEventListener#handleEvent (line 236) is not handling the case of SWT.Resize for the detached window. If anyone interested in debugging this, I suggest checking Shell(Widget)#sendEvent, to verify the event is not filtered out.
Just wanted to add that switching perspectives has the same problem as minimize.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
