Python GTK3：带有图像和标签的按钮，并在点击事件后获取标签值

Question

我正在尝试获取网格内的标签值，而该网格在单击事件后位于按钮内。

这是我的部分代码：

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..有什么想法吗？谢谢

希望此代码对您有所帮助：

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()
