Menubar widget causes first right-click on plasma-desktop to instantly hide

[Jonathan Thomas]

Binary package hint: plasma-widget-menubar

If you have a non-maximized application that is using the menubar, right clicking on the desktop will not work. When you try to do so, the context menu for plasma-desktop instantly disappears.

I can replicate this on plasma-netbook too, although on plasma-netbook once focus shifts to the workspace (and the apps aren't visible anymore) then it works.

Apologies to Graham Riddell for the bug subscription. I miss clicked. Unfortunately, I can't unsubscribe you, you'll need to do it yourself.

I can't reproduce it here, is it still valid?

[Jonathan Thomas (echidnaman)]

Yup, still happening with the latest updates.

I had a look at fixing that one and it's nasty: when one right-click the desktop, the desktop window gets focus, thus the menubar widget creates a desktop window menubar. To do so it creates a Plasma::ToolButton, which embeds a QToolButton. It seems creating the QToolButton causes the menu to go away, I assume that since the button is created as a standalone window (at least at construction time), it is perceived as a new toplevel window, forcing the window manager to close the popup menu.
