Hi,<div><br></div><div>We have an software EMAN2 which choose PyQt4 to implement the GUI interface. Which works fine until recently I upgrade my PyQt4 to 4.5.4. After the upgrading, I lose response to all mouse event, including mouse clicking on a 2D/3D image and mouse wheel (I use wheel to zoom in or out of image). I tried PyQt4 4.5.2, still no response for all mouse event. The mouse works perfectly fine for PyQt4 4.4.4. I doubt all 4.5 versions will not work. Could somebody help?</div>
<div><br></div><div>I post some pieces of code for my mouse wheel event, hope it help: </div><div>class Main2DWindowEventHandler(BoxEventsHandler):</div><div> def __connect_Signals_to_slots(self):</div><div> QtCore.QObject.connect(self.main_2d_window.emitter(), QtCore.SIGNAL('mousewheel'), self.mouse_wheel())</div>
<div><br></div><div>class EMImage2DEmitMouseMode(EMImage2DMouseEvents):</div><div> def mouse_wheel(self, event):</div><div> seld.mediator.emit(QtCore.SIGNAL('mousewheel'), event)</div><div><br></div><div>
#actual slot function</div><div>class EMImage2DModule(EMGUIModule):</div><div> def weelEvent(self, event):</div><div> #blah, blah</div><div>I tried to print out message in this slot function. It prints out in PyQt4.4.4 but nothing got printed in PyQt4.5.*.</div>
<div><br></div><div>Since it works fine with PyQt4 4.4.4 and previous versions. I doubt something new in 4.5.* make it not work.</div><div><br></div><div>Thanks for any comments, </div><div><br>Grant<br>
