New Function: WindowToBack()

Could a function be added to send a Hollywood window to the back---placing it behind other open windows?
A related request:
Would it be possible to make a Hollywood display remain in the back, so that no other window can be placed behind it?

Putting a window to the back of the z-order is possible but making it remain there isn't, at least not in a platform-independent, clean way. AmigaOS has the concept of backdrop windows but on other operating systems such things aren't really supported.

I have somehow related issue myself, you can bring a screen to front with
ShowScreen from the Amiga support library, but can you send screen to back in any way? If not, could that be added?
I created a custom screen depth gadget for my fullscreen borderless program, which doesn't have the standard depth gadget, and I didn't figure a way to send it back. I now bring the desktop screen to front to "simulate" the effect, but it doesn't stack the screens in the same order it would go with the system features. Now the Hollywood screen is left next to the front screen and not put to the last as it would go with the system screen gadget or command-m etc.

Yes, should be possible to add this to the AmigaOS support library.

Code: Select all
- New [Amiga]: Added HideScreen() command which sends a screen to the back of the display; the
optional argument is the name of a pubscreen; if omitted, the front-most screen is sent to the
back which is typically what you want

But it still would be really nice to have on Amiga platforms, for example, I would really love to have it for my widgets program
There are some other platform specific features already, so maybe this one too?
BTW. is the a way to check which screen is front on Amiga? I can check on which screen my program is running with #ATTRPUBSCREEN, but can I check is that screen on front or not? GetPubScreens() seem to return the order they were created? But not the order they're currently stacked...

It should be possible to add this quite easily. I'll see if I can come up with something.

Code: Select all
- New [Amiga]: HideDisplay() accepts a new optional argument now; if this argument is set to TRUE, the
display will be hidden by moving it behind all other windows, i.e. to the bottom of the window stack
- New [Amiga]: Added GetFrontScreen() command; this will return the name of the public screen that is
currently up front or an empty string in case a non-public screen is currently the frontmost screen;
note that because of the multitasking environment screens managed by other programs can go away at
any time so there is no guarantee that the screen is still there (or front) when GetFrontScreen()
returns
