Action shortcut missing in context menu

Rory_1

My app uses the same menu structure for the main menu and the context menu for the central widget. The code looks like this:

// main menu
menuBar()->addAction(fileGroupAct);
menuBar()->addAction(editGroupAct);
menuBar()->addAction(goGroupAct);
menuBar()->addAction(filterGroupAct);
menuBar()->addAction(sortGroupAct);
menuBar()->addAction(viewGroupAct);
menuBar()->addAction(windowGroupAct);
menuBar()->addAction(helpGroupAct);
menuBar()->setVisible(true);

// main context menu
mainContextActions = new QList<QAction *>;
mainContextActions->append(fileGroupAct);
mainContextActions->append(editGroupAct);
mainContextActions->append(goGroupAct);
mainContextActions->append(filterGroupAct);
mainContextActions->append(sortGroupAct);
mainContextActions->append(viewGroupAct);
mainContextActions->append(windowGroupAct);
mainContextActions->append(helpGroupAct);

// Central Widget mode context menu
centralWidget->addActions(*mainContextActions);
centralWidget->setContextMenuPolicy(Qt::ActionsContextMenu);

Main menu with shortcuts
alt text

Context menu without shortcuts
alt text

How do I get the context menu to show the action shortcuts?

Hi @Rory_1, welcome!

Honestly, I'm not aware of an application showing shortcuts in a context menu. Most likely because of that, no such mechanism is implemented in Qt. But that is just guessing.

Also, it looks like your context menu contains the same items as you main menu. But usually, a context menu contains context sensitive items, i.e. items that only apply at the position where the menu was opened.

This question shows it is possible: https://forum.qt.io/topic/82367/adding-more-actions-to-the-context-menu-of-a-spreadsheet-app

Understood. My app is designed to hide the main menu for a more compact form and for the menu to be accessible during slideshow mode, where only the image is visible.

Why don't you download its source and have a look at how it achieves it, then?

I did, but I don't see why it is working in that example based on looking at the code. I haven't been able to get the project to run yet to confirm it actually does what the image suggests though.

@Rory_1
I don't know, but your screenshot looks different from that example. Is it possible that this uses a native OS/UI/desktop functionality to display the context menu, and that works for the icon on some other OS but not yours?

Rory_1

@JonB

That's a good point. I'll fiddle around with my style sheet to see if it is the culprit.

Rory_1

@JonB
I tried without my style sheet and I still get the same thing so that does not appear to be the issue.

Are you Qt 5.10? Are you https://github.com/lxde/lxqt/issues/1426 ??

Yes, I am on 5.10 and that appears to be the issue - thanks for finding it!! Seems like an odd "improvement". I really appreciate the help.

BTW I did get the spreadsheet app to run and I did not see the shortcuts.

Probably also requires the fix for your 5.10.

@JonB

Right.

I hate to mark this issue as solved, but if that's the way Qt is going I guess I'll just have to live with it. I'll take a look at subclassing QStyleHints.

JonB

@Rory_1
As per http://doc.qt.io/qt-5/qstylehints.html#showShortcutsInContextMenus-prop, this is a deliberately-introduced option now.

Rory_1

@JonB

I understand - doesn't mean I have to agree with it. I've been thinking about how I would go about subclassing QStyleHints. I know how to subclass a widget that I can then use, but how do I subclass something I am not calling myself. Do I have to subclass QGuiApplication? Seems like that might be risky.

Hi
Its being debated.
https://bugreports.qt.io/browse/QTBUG-61181?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel&showAll=true
So there might come a Set method. Currently its read only :(

Thanks for the info. Much appreciated.
