popup_during_fullscreen: why can't we just show it
In the user documentation, we can see these bits:
When you are in fullscreen mode, some applications still open popup windows (take Xpdf for example). This is because these applications may not be aware that they are in fullscreen mode (they do not check the corresponding hint). There are two things which are possible to do in this situation:
Just ignore the popup (don’t map it). This won’t interrupt you while you are in fullscreen. However, some apps might react badly to this (deadlock until you go out of fullscreen).
Leave fullscreen mode. This is the default.
I can't understand why we can't just show the popup, floating over the application, like it's done any other time ?
I think that most of the time, the popups from the fullscreen application are just mandatory, there is no way you can't ignore it ?
For instance, I'm thinking about a text editor, File->Open raises a popup, and it's logical for the application to block until you selected a file, and there is no way for the app not use this popup, every if it checked the fullscreen flag ...
Is there any "system level" reason to prevent that, or am I missing something ?
