Python GTK3:带有图像和标签的按钮，并在点击事件后获得label值

Question

单击事件后，我试图获取位于网格内的标签值，该网格位于按钮内。

这是我的代码部分：

for one_text in text_list:
label_for_button = Gtk.Label(one_text)
label_for_button.set_line_wrap(True)
image_for_button = Gtk.Image.new_from_file("img.png")
grid_in_button = Gtk.Grid()
grid_in_button.add(image_button)
grid_in_button.attach_next_to(label_for_button, image_for_button, Gtk.PositionType.BOTTOM, 1, 2)
grid_in_button.show_all()
button.add(grid_in_button)
button.connect("clicked", self.on_button_clicked)
def on_button_clicked(self, widget):
# here i wanna get the value of the label_for_button

帮助。。知道吗？感谢

希望这段代码能有所帮助：

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()
