[英]Glade/GTK3 and radio buttons
Using this tutorial https://python-gtk-3-tutorial.readthedocs.io/en/latest/builder.html I have created a similar Glade GUI which has a quit button and two radio buttons A and B. I am quite confused by radio buttons. 使用本教程https://python-gtk-3-tutorial.readthedocs.io/en/latest/builder.html我创建了一个类似的Glade GUI,它具有退出按钮和两个单选按钮A和B。我很困惑通过单选按钮。
If I use GtkButton or GtkToggleButton the rba function triggers twice, I assume it triggers both when the button becomes the active one and when it becomes the inactive one. 如果我使用GtkButton或GtkToggleButton,则rba函数会触发两次,我假定它在按钮变为活动按钮和非活动按钮时都触发。 Is that right?
那正确吗?
I don't need anything complicated, either 我也不需要任何复杂的东西
a function which triggers when a button is clicked, within which I can find out which one is now active, OR 一种单击按钮时触发的功能,在该功能中我可以发现哪个按钮现在处于活动状态,或者
a function for each button which triggers only when its own button is clicked. 每个按钮的功能,仅当单击其自己的按钮时才触发。
I also need to be able to switch which button is active, preferably without triggering the/its function. 我还需要能够切换哪个按钮处于活动状态,最好不触发其功能。
Have I misunderstood something essential? 我是否误解了一些必不可少的东西?
EDIT: After much experimentation, I have found that second bit of code works for a signal GtkToggleButton>toggled>rba. 编辑:经过大量实验,我发现第二部分代码适用于信号GtkToggleButton> toggled> rba。 I can't get anything similar to work for the other button though!
但是我无法获得与其他按钮相似的功能!

This is one of the ways to set up Python + Gtk properly with the basic idea you already have. 这是使用已有的基本思想正确设置Python + Gtk的方法之一。 It works for me.
这个对我有用。
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import sys
class GUI:
def __init__ (self):
builder = Gtk.Builder()
builder.add_from_file('test.glade')
builder.connect_signals(self)
window = builder.get_object("window1")
RBA = builder.get_object('radiobuttonA')
RBA.connect('toggled', self.rba)
RBB = builder.get_object('radiobuttonB')
RBB.connect('toggled', self.rbb)
window.show_all()
def buttonQuit(self, menuitem): # quit with Quit button
Gtk.main_quit()
def on_window1_destroy(self, window): # close window with 0 or X
Gtk.main_quit()
def rba(self, radiobutton):
print('in rba')
print (radiobutton.get_active())
def rbb(self, radiobutton):
print('in rbb')
print (radiobutton.get_active())
def main():

if __name__ == "__main__":
sys.exit(main())
With the code below and Glade sending 'clicked' signals, it triggers both the 'switched on' and 'switched off' functions, but only once each and I can test which is on. 通过下面的代码,Glade发送“单击”信号,它会触发“打开”和“关闭”功能,但每个功能仅触发一次,我可以测试哪个功能打开。 This will work for me.
这对我有用。 I have changed some names to 'dummy' to remind me that these don't seem to have any function that I want.
我将某些名称更改为“虚拟”,以提醒我这些似乎没有我想要的功能。 Thanks gtknerd!
谢谢gtknerd!
