希望这段代码有帮助：

import gi

gi.require_version('Gtk','3.0')

from gi.repository import Gtk,GdkPixbuf

def btn_clicked(widget):

    print(widget.get_label())

pixbuf = GdkPixbuf.Pixbuf.new_from_file_at_scale(filename="img.png", width=24, height=24, preserve_aspect_ratio=True)

img = Gtk.Image.new_from_pixbuf(pixbuf)

btn = Gtk.Button(label='some text',image=img,)

btn.connect('clicked',btn_clicked)

win = Gtk.Window()

win.connect("destroy", Gtk.main_quit)

win.add(btn)

win.show_all()

Gtk.main()
