How to find out the currently selected display?

[Flinx]

I'm searching for a way to determine which display is currently selected. Is this possible?

I guess you have searched the documentation pretty well, and I didn't see anything with a very quick look either.

Maybe something like this as a work-around:

Code: Select all

Function p_GetSelectedDisplay()
	Local type, id = GetAttribute(#DISPLAY, 0, #ATTROUTPUTDEVICE)
	If type = #DISPLAY Then Return(id) Else Return(-1)
EndFunction

It returns -1 is something else than a display is selected as the output device (brush, bgpic...), so in that case you must end the previous selection.

Thanks! I hadn't found that. I'm not sure in which situations it fails this way, but at least it's better than nothing.
I had tried to make the table monitor I recently presented here as universally usable as possible, because it helped me quite a bit.
Since it requires a SelectDisplay, I have to switch back to the current display at the end of the interval function. I’ve now integrated your function; here’s the current version. I’ll keep experimenting a bit more.

Maybe something like this as a work-around:

I'd say that's not the work-around but the official solution Of course I could add a real function like GetOutputDevice() or something but I think that would do exactly the same as your GetAttribute(#DISPLAY, 0, #ATTROUTPUTDEVICE) or are there any cases where that doesn't do what it should? I think it should be a perfectly safe solution.

Now that I’ve taken a closer look, I realize my question was too specific. I had imagined it too simple. “Change the output device within an interval function and restore the previous state at the end of that function” is much more complicated than I had expected at the time. Okay, I should have guessed that, since I’ve already used different output devices before, but at that moment I was just focused on the display.
Let’s see if I can find a solution for this, but maybe it’s not even possible with the available commands, since the various Select variants have a lot of parameters as well.
Or does anyone see a quick and easy solution?
