Preventing a QDockWidget from being closed by keyboard shortcuts if it should not be closable

[l3u_]

Hi all,

I just found again a bug report I filed ca. one year ago: https://bugreports.qt.io/browse/QTBUG-126418

The relevant problem is: A QDockWidget that is declared as non-closable but as floatable cannot be closed by clicking an "X" button (it's omitted then), but one can actually close such a floating dock nevertheless by using a keyboard shortcut (Alt+F4).

After that, there's no way to re-show that closed dock, as the menu bar's context menu containing checkboxes for all dock widgets is grayed out (it becomes enabled when adding docks with the QDockWidget::DockWidgetClosable feature set). The only way to get the dock back is to delete the window state from the rc file.

My understanding is that a QDockWidget that is marked as not closable should not only not be closable by omitting the "X"/"Close" button, but also an attempt to close it using keyboard shortcuts should be ignored, to also prevent it from closing this way.

@Axel-Spoerl Now that I know that you're the QDockWidgets expert here – is this a bug or is it a feature!? ;-) Do I have to prevent this in my code, or do you agree that Qt should take care of this?

Cheers, Tobias

Looks like the bug doesn't reproduce anymore.

Hi Tobias,
that's definitively a bug, not a feature. Non-closable is not limited to the x-button. Maybe you wanna assign it to me.
Cheers

@l3u_ He means go to https://bugreports.qt.io/, create a bug report and assign to his name :)

There is already a bug report. But I don't see how I could assign it …

[JonB]

@l3u_ OIC. I don't think you/I have permission? Wait for @Axel-Spoerl to return here.

Done

Thanks! So is it correct one needs special permissions to do so?

@Christian-Ehrlicher Hey, was it intentional to assign the bug to "Axel Sanwald" and not to @Axel-Spoerl ?

No, it was mistake on my little mobile phone.

Hey, I was gone for some days.
Will look into it this week!

Hi all,
I looked into it a bit and replied in the Jira ticket.
Please answer there.
