在python中有一个小应用程序，可以禁用或启用从相机到debian操作系统的内核模块。程序运行良好，但现在我想用GTK更改tkinter。我用glade制作了一个新的gui，现在我有了在GTK中运行的新Python应用程序。除画布外，程序运行良好。老节目与tkintershow"；照相机被加载"；或"；照相机未加载"；。我想对gtk做同样的事情，但我不知道该怎么做才能显示相同的文本。我从pdf或youtube视频中读了很多例子，但我没有找到任何解决方案。
我感谢任何帮助！
谢谢

如果您只想使文本显示
- 在该位置定义Gtk.Label(使用Glade(
- 将其标签定义为空(即清除Glade中的标签(
- 给Gtk.Label一个ID，以便稍后在主代码中访问它
- 必要时，使用更改标签
your_label_id.set_text('camera not loaded')或者其他什么
您也可以在Glade中设置标签文本，然后用your_label_id.hide()或...show()
