How to set eyed3.tag.image_data as Gtk.Picture picture

Is there any way to set Gtk.Picture content, neither to the file nor to resource. I have eyed3 parsed audio cover, but I don’t know any way to set it as image in Gtk.Picture. I tried GdkPixbuf, but it does not work.

If image data is in bytes and in a format supported by GTK, then you can can convert them to GLib.Bytes and create a new Gdk.Texture with them (see Gdk.Texture.new_from_bytes ) then you can use that texture as the paintable of the Gtk.Picture.

I can’t create a variable of type Gdk.Texture. I am getting this error TypeError: cannot create instance of abstract (non-instantiable) type GdkTexture’`

This is my code:

from gi.repository import Adw
from gi.repository import Gtk
from gi.repository import GLib
from gi.repository import Gdk


@Gtk.Template(resource_path="/com/github/dzheremi/lrcmake/gtk/components/songCard.ui")
class songCard(Gtk.Box):
    __gtype_name__ = 'songCard'

    cover = Gtk.Template.Child()
    song_title = Gtk.Template.Child()
    song_artist = Gtk.Template.Child()

    def __init__(self, track_title, track_artist, track_cover = None):
        super().__init__()
        self.cover.set_filename('/home/dzheremi/Pictures/note.png')
        self.song_title.set_property('label', track_title)
        self.song_artist.set_property('label', track_artist)
        print(track_title, track_artist)
        if track_cover != None:
            image_bytes = GLib.Bytes(track_cover)
            image_texture = Gdk.Texture()
            image_texture.new_from_bytes(image_bytes)
            self.cover.set_property('paintable', image_texture)

You cannot create a Gdk.Texture instance with Python’s normal form constructor; additionally, Gdk.Texture instances are immutable post construction, so you can’t call constructor or setter methods on them:

So how should I then set paintable of cover to Texture if I can’t create it?

I edited your code to show you how, but just in case it wasn’t clear:

if track_cover != None:
    image_bytes = GLib.Bytes(track_cover)
    image_texture = Gdk.Texture.new_from_bytes(image_bytes)
    self.cover.props.paintable = image_texture

Thank you very much! You have kept me interested in creating GTK applications.
