When I build our application against Qt 5.1.0 (qmake version 3.0) a double-click results in the following sequence of events:
mousePressEvent() mouseReleaseEvent() mousePressEvent() mouseDoubleClickEvent() mouseReleaseEvent() The same application built against Qt 4.8.2 gives this sequence: mousePressEvent() mouseReleaseEvent() mouseDoubleClickEvent() mouseReleaseEvent() Note that the second mousePressEvent is not there. I see this difference on both Macintosh and Windows. The Qt 5 behavior makes it difficult to handle a double-click event. I am aware that you have to expect a mousePressEvent plus the mouseDoubleClickEvent, but I don't expect two mousePressEvents. So my questions: 1) Is this the expected behavior for Qt5? 2) If it is by design, rather than a bug, how is my code supposed to know that the second mousePressEvent is actually the second click of a mouseDoubleClick event? Thank you for any insight! -John Weeks
