The time duration before the highlight disappeared was so consistent, it felt like it must be controlled by a timer.</div><div><br /></div><div>So I installed an event filter on the menu, and sure enough, shortly after typing 'A' to select the first menu item, the menu receives a <font face="Consolas" size="3" style="font-size: 16px;">Timer</font> event, followed by an <font face="Consolas" size="3" style="font-size: 16px;">UpdateRequest</font> event.</div><div><br /></div><div>It isn't obvious to me why it does this. Indeed, if I just suppress it:</div><div><br /></div><div><font face="Consolas"> def timerEvent(self, event):</font></div><div><font face="Consolas"> return</font></div><div><br /></div><div>it seems to work fine. But I expect someone must have thought there was a good reason for it at some point, and I imagine if I took this approach, it would probably eventually bite me somehow.</div><div><br /></div><div>Another possible approach is to query the active action from <font face="Consolas" size="3" style="font-size: 16px;">timerEvent()</font> and save it, prior to calling <font face="Consolas" size="3" style="font-size: 16px;">super()</font> (which I presumes is responsible for the reset), then use that to reselect it afterward:</div><div><br /></div><div id="xf7016701743b41ac8e1b49e767b061cd"><div style="background-color:rgba(0,0,0,0);margin:0px;"><font face="Consolas"> def timerEvent(self, event):</font></div><div style="background-color:rgba(0,0,0,0);margin:0px;"></div></div><div><font face="Consolas" size="3" style="font-size: 16px;"> active_action = self.activeAction()</font></div><div><font face="Consolas" size="3" style="font-size: 16px;"> super().timerEvent(timer)</font></div><div><font face="Consolas" size="3" style="font-size: 16px;"> self.setActiveAction(active_action)</font></div><div style="font-size: 16px;"><br /></div><div>This seems to work also.</div><div><br /></div><div>Thank you again for your help!</div><div><br /></div><div>/John</div></div></div>
