In searching around, I found some examples that reimplemented <font face="Cascadia Code">drawItemText()</font> and some that reimplemented <font face="Cascadia Code" size="3" style="font-size: 16px;">drawControl()</font>. The former seemed more intuitive to me (goes to show you what I know), so I went down the wrong rabbit hole.</div><div><br /></div><div>One more question if you will: I've attached a newer version of my original sample, based on your suggestion.</div><div><br /></div><div>If I install the proxy style for the menu with:</div><div><br /></div><div><font face="Cascadia Code" size="3" style="font-size: 16px;"> file_menu.setStyle(Style())</font></div><div><br /></div><div>it works (items are right-justified). But the menu has a slightly different appearance (on my system, rounded corners). Not surprising, I suppose. No arguments are passed to the <font face="Cascadia Code" size="3" style="font-size: 16px;">Style()</font> constructor, so it's creating one from scratch.</div><div><br /></div><div>I'd think the proper thing to do would be to derive the new style from the menu's previously-existing style:</div><div><br /></div><div><font face="Cascadia Code" size="3" style="font-size: 16px;"> file_menu.setStyle(Style(file_menu.style()))</font></div><div><br /></div><div>Wondering if this is a/the proper thing to do? It seems to work, in that the menu then has the proper appearance (that is, one that is consistent with its appearance if I don't assign the proxy).</div><div><br /></div><div>But then when I exit the app, there's a long(ish -- about two seconds) delay. If I run the app from a Command Prompt window, it's a couple seconds before the command prompt reappears -- I think the app is not merely exiting, but actually crashing. Which makes me wonder if this is somehow not right?</div><div><br /></div><div>Thanks again!</div><div><br /></div><div>/John</div>

<div>Hello again PyQt sages. Hoping for some insight here -- despite a few hours' time fiddling with this, I don't seem to even be getting past square one.<div><br /></div><div>I'm trying to modify display of items in a <font face="Cascadia Code">QMenu</font> using <font face="Cascadia Code" size="3" style="font-size:16px">QProxyStyle</font>. Basically, I've defined a class named <font face="Cascadia Code" size="3" style="font-size:16px">Style</font> that derives from <font face="Cascadia Code" size="3" style="font-size:16px">QProxyStyle</font>, and re-implements <font face="Cascadia Code" size="3" style="font-size:16px">drawItemText()</font> (which, just for starters, tries to right-justify the menu item text).</div><div><br /></div><div>I create a <font face="Cascadia Code" size="3" style="font-size:16px">QMenu</font> object, create an object of the <font face="Cascadia Code" size="3" style="font-size:16px">Style</font> class, and call <font face="Cascadia Code" size="3" style="font-size:16px">.setStyle()</font> to set it as the menu's style.</div><div><br /></div><div>It may or may not be the case that my <font face="Cascadia Code" size="3" style="font-size:16px">drawItemText()</font> implementation successfully right-justifies the text. I'll never know, because it never gets called. What (probably really basic thing) am I missing?</div><div><br /></div><div>Thanks!
