[SDL] Feature request, getting the screen size of the keyboard

[EternalLands]

Is there a way to get the size of the OSD keyboard on touch based devices?
The reason I am asking is that I would like to know where to show the user input text, and some keyboards are larger than others (plus, many keyboards can have a size set by the user).
I am interested mainly for Android, although it would be nice to have a universal function.

It is a while ago that I looked into this, but I believe you will get a
window event (like resized or size changed) that tells you the new window
size that you can render on, while the keyboard is shown. From that you can
compute the size of the keyboard.

That won't work for a tablet, where a keyboard can float, or not cover the
whole bottom of a screen on iOS.

I added this to an old codebase, but need to implement again for SDL 2.
Here's some of the relevant code:


iOS

https://github.com/openfl/lime/blob/legacy/legacy/project/src/iPhone/UIStageView.mm#L2276
https://github.com/openfl/lime/blob/legacy/legacy/project/src/iPhone/UIStageView.mm#L3159-L3169
https://github.com/openfl/lime/blob/legacy/legacy/project/src/iPhone/UIStageView.mm#L2979-L2982


Android

https://github.com/openfl/lime/blob/legacy/legacy/templates/android/template/src/org/haxe/lime/GameActivity.java#L77
https://github.com/openfl/lime/blob/legacy/legacy/templates/android/template/src/org/haxe/lime/GameActivity.java#L133-L141
https://github.com/openfl/lime/blob/legacy/legacy/templates/android/template/src/org/haxe/lime/GameActivity.java#L335-L349


This code isn't perfect, but it's something I've been meaning to revisit it

I don’t know how the SDL implementation on Android works, but SDL’s code on iOS makes sure the on-screen text area you specify with SDL_SetTextInputRect is always visible, by pushing the window up if needed while the keyboard is shown.

The above function is available on all platforms.

That won't work for a tablet, where a keyboard can float, or not cover the whole bottom of a screen on iOS.
