How do I create a modeless message box?

[Knj.Tkm]

I want to create a modeless message box.

There are no buttons or progress bars to display, only messages.
I would also like the system to terminate when the work is completed or when it fails.

Is it possible to create such a message box?

Yes. Solution depends on whether we are talking about QtWidgets or QtQuick, but in general:

• make a custom dialog, without buttons
• set it to be application modal
• reimplement close event to prevent users from closing the dialog with Alt+F4

I would also like the system to terminate when the work is completed or when it fails.

Solution depends on the operating system, but in general you need to use QProcess::startDetached and run system command to shut down or reboot the device.

How does this address OP's request for a modeless message box? Seems to me to be the opposite. Why not a modeless one? setModal(false), use show() instead of exec()?

@JonB you're right, I somehow assumed such a message box should not be possible to hide behind other windows.
