Focus Stealing

[Harsh13]

Once the Qt application is opened, how to ensure that it cannot be switched to a different screen?

Hi @Harsh13 and welcome

the answer is you can't that is managed by your Operation System/ Window Manager.

Maybe there's a way to archive what you want, what exactly do you want to prevent?

Consider this scenario- I've changed the value of a button and without confirming the value, I switch to another screen. Later when I switch back to the application, the value is automatically confirmed which is not the expected behavior.

@Harsh13 hi,
what do you mean by " I've changed the value of a button .. without confirming the value " ?

maybe this can help Dialog Windows

[Harsh13]

There's a button, on click of which, the value gets incremented and when clicked again, the changed value gets confirmed. If incremented and not confirmed, a color animation(similar to blinking ) begins for 30 seconds.
Now if I click on the button and increment the value without confirming it and switch to a different screen and then come back to the application, it should remain on the value without getting confirmed.

@Harsh13
that is the default behavior.

Buttons don't emit the clicked signal during focus change.

Button as in a rectangle which when clicked performs the action
