Setting the window icon

Hi!
I am wondering, has anything been made in this matter? Is there at least an API people could start implementing?

[isavegas]

Perhaps the best way to handle it would be a feature flag that uses a crate like image and abstracts the icon assignment for whatever window manager you're using. Of course, anything that requires an external image file would require saving to the file at runtime or a build.rs for it, but it should be possible.

I'd probably make some sort of system that just takes a simple RGBA bitmap in the form of a &[u8] and turns it into whatever platform-specific format is necessary. It's a bit of a hack I expect but hopefully a very simple hack...

I plan on using WindowBuilderExt and WindowExt for this, since 1) it only seems relevant on Windows and X11, and 2) X11 wants ARGB while Windows wants paths (and is picky about what it accepts).

Implementing this on X11 will most likely be trivial.

It's too fiddly to make Windows also take ARGB or something like that? (I don't know much about Windows.)

To be honest, my main rationale was that the docs for CreateIcon looked intimidating. Since you asked, I gave it a shot today, and it was actually pretty easy.

So, now I can provide a consistent API that expects RGBA. I'll also include an example program that demonstrates how to use image to set the icon using any image file.
