Application Window Icon #43

Closed Guillaume227 closed 6 months ago

Guillaume227 commented 1 year ago

Based on that (old-ish) imgui issue: https://github.com/ocornut/imgui/issues/2715 I am wondering whether providing a way to display a main window icon should be part of what the battery-included, cross platform hello_imgui approach should offer.

I have looked at the doc and the hello_imgui_app example but it's not obvious how to achieve that currently.

Application icon and window is inherently handled wildly differently on different platforms.

On windows, you can set it by using code
On MacOS, iOS, Android you have to provide the icon an the application bundle (i.e a set of resources that come with the app)
On Linux this is also handled at the Window manager level + may be by code

The expected icon file format also differs wildly (bmp, icns, etc)

The expected icon size and the number of expected variations also differs (Android may ask up to 6 variations IIRC).

Ok - I naively thought it was more standardized. Maybe the case for providing an example for each platform that new comers like me can just use as a template? In any case, we can close this issue.

@Guillaume227 : lots of improvements were made for applications icons.
