Re: Desktop as transient window

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The desktop is not a window. It could be in some desktop environments,
but is not always. In fact, in some desktop environments, there is no
desktop window or desktop concept at all. There is no standard
protocol to fetch the desktop window if it exists, either.

The reason that unparented dialogs are discouraged are because in most
cases, dialogs shouldn't just pop up out of the blue -- they should
come from an understandable user action or application window to tie
it back to. Otherwise, you might see a random dialog pop up at some
point without knowing where it came from.

While we can often detect the parent window automatically, there are
sometimes cases where we cannot, and we warn to let you know that this
is one of these cases, so you can go and fix it. It is OK to ignore
that warning.
