GTK 4 used only 48x48 application icon that leads to fuzzy icons. GTK2 works fine

It includes the gtk_window_set_icon_name and gtk_window_set_default_icon_name functions (and also including the icons in Gressource way i guess ? ).

It’s entirely up to you if you want to provide a default icon using those functions, but only as a fallback mechanism. And, as a fallback, it will have limitations.

@Nilsou

Am i good ?

Yes.

In general, you can follow the documentation on the GNOME developer documentation website, which is mainly a recap of the freedesktop specs.

@Nilsou

I notice though that it is a bit fuzzy : documentation is not really clear about those points and I guess that a multi system application need to have the two system to ensure compatibility with OS that do not follow the freedesktop specification ?

It’s been 20 years since the introduction of the desktop entry and the base directory specifications in the Linux/freedesktop world: there are no “OSes” that do not follow the freedesktop specification, unless you fell into a time hole to 1997. The entire point of those specifications is to ensure that you only have to target a single platform instead of a collection of random components.

Ok, i didn’t want to talk about Linux system particulary but also Windows etc.

Thank you for your answering, i will try by defining a .desktop file and icon file according to the freedesktop way.

I have to notice though, that the fallback system seems buggy, at least in my case because it gives bad result compared to the same apps in GTK2. Do not know why.
