Drag and drop event coordinates no longer correct for plugin child windows (gtk)
When running Komodo on Mozilla 17.0 we notice that the DOM drag/drop events that originate over the plugin are incorrect (note that Komodo uses a NPAPI plugin for it's text editor) - the events have higher x/y values whose offsets are increased by the distance the plugin is positioned from to the top/left corner of the main nsWindow. It seems that the following change is the cause: https://hg.mozilla.org/mozilla-central/rev/3c6358d51fa5 @@ -3381,180 +3346,16 @@ nsWindow::DispatchDragEvent(PRUint32 aMs - innerMostWidget-> - DispatchDragMotionEvents(dragServiceGTK, nsIntPoint(retx, rety), aTime); was changed to: @@ -5968,50 +5769,100 @@ drag_motion_event_cb(GtkWidget *aWidget, + return nsDragService::GetInstance()-> + ScheduleMotionEvent(innerMostWindow, aDragContext, + nsIntPoint(aX, aY), aTime); and thus it stopped using the special "retx" and "rety" variables that hold the corrected coordinates (in the case of a plugin child window). Note: Asking review from karlt because that's who made the change.

Comment on attachment 679342 [details] [diff] [review] Fixes the problem - using retx and rety variables again Thanks very much. I'm a little surprised we get these signals for events over the plugin window. Is the plugin running in the same process as its host?

Yes, Komodo is using an in process plugin in this case.
