Render emojis with GTK+3 on a Cairo surface

[giutor (Giuseppe)]

Hi,

is it possible to render emojis on a cairo surface? Sorry if I’m still using gtk+3, my software is large and porting it to gtk4 would require a lot.

Thanks

You can ask a GtkWidget to create a PangoLayout with the emoji (expressed as a UTF-8 string); then you can use the PangoCairo API to render a PangoLayout on a Cairo surface.

Grazie mille Emanuele, very kind!

Do you know if I can get the list of the UTF8 strings somehow with gtk+3? I noticed gtk_emoji_chooser_new() is only available in gtk4.

You have to look on any website with the list of Unicode emojis; those typically list various formats/code points.
