新手 Glade 用户被单选按钮搞糊涂了

Question

我有一个 Glade GTK Gui，它是我几年前写的 CLI 程序的前端。

有许多字段供用户填写。理论上，这些将在用户按“提交”时处理，例如 HTML。（否则，他们可以按“不保存退出”）

我实际上可以收集 GtkEntry 字段并使用它们的内容。 但是我对单选按钮感到困惑。 在 GUI 中，我似乎根本无法按下按钮，而且我不知道如何获取它们要传达的内容。

我包括了一个程序，它的设计目的只是显示 GUI 并尝试测试其功能。

我以 XML 的形式包含了这个程序和 glade 文件。

#!/usr/bin/env python

import gi

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

from gi.repository import Gtk

import sys

builder = Gtk.Builder()

class GUI:

    def __init__ (self):
        builder.add_from_file('EntryForm.glade')
        builder.connect_signals(self)
        window = builder.get_object("window1")
        window.show_all()
        
    def onSubmitButton(self, button):
        idir = builder.get_object('inputdir')
        result = idir.get_property('text')
        print(f'inputdir = {result}')
        odir = builder.get_object("outputdir")
        result2 = odir.get_property("text")
        print(f'outputdir = {result2}')
        builder.get_objects()
        builder.get_object('radiobuttons')
        x = radiobuttons.get_label()
        print (f'radiobutton select is {x}')

    def onDestroy(self, menuitem): 
        Gtk.main_quit()
        
    def on_window1_destroy(self, window): # close window with 0 or X
        Gtk.main_quit()

        
def main():

    app = GUI()
    Gtk.main()

if __name__ == "__main__":  
    sys.exit(main())

并且，正如所承诺的那样，.glade 文件。

我不希望任何人仔细研究源代码，但我至少会感谢单选按钮上的一些指示，特别是如何获取它们的内容。

谢谢，

Answer 1

在.glade ，您使用id="NameButton"定义RadioButton ，因此您需要

name_button = builder.get_object('NameButton')

print( name_button.get_active() )

但问题是每个RadioButton都被视为单独的组，当组只有一个按钮时，它总是True 。

按钮应该成组。 第二个和第三个RadioButton应具有 ID 为第一个RadioButton的属性group

<property name="group">NameButton</property>
