Qt window automatically closes the window when clicking outside the window area

[Jun_]

I have a button that needs to show or hide a window. At the same time, when the window is displayed, clicking anywhere outside the window needs to hide the window. How can I achieve this in qml?

I used the activefocusitemchanged signal and closed the window in the signal, but at this time if I click the button, it will trigger the opening again, which should have been closed.

What sort of "window" is it? The sort of behaviour you want is supported by Popup. See closePolicy property.

Thanks for your reply.

Not only does the closing strategy require the mouse to click outside to disappear, but also a button to control closing and showing. Clicking on the button triggers the closing strategy at the same time, which will cause the window to close and then open again.
