MultiWindow错误Glade，Gtk和Python
[英]MultiWindow error Glade, Gtk and Python
问题描述
I am making an interface where you have to be logged to enter. 
我正在创建一个必须登录才能进入的界面。 So at sign in window I put a button to open a modal window (about dialog). 因此，在登录窗口中，我放了一个按钮以打开模式窗口（关于对话框）。 It works fine, but just once, I mean: this window can be opened and closed, but if you try again, it fails. 它可以正常工作，但仅一次，我的意思是：可以打开和关闭该窗口，但是如果再次尝试，它将失败。 I can not realize why and I am quite begginer. 我不知道为什么，我很开始。 The Glade code is: Glade代码是：

And my python code is: 我的python代码是：
#!/usr/bin/python
from gi.repository import Gtk
class Handler(Gtk.Window):
def onDeleteWindow(self, *args):
self.destroy()
Gtk.main_quit(*args)
def onAboutPressed(self, button):
about = builder.get_object("aboutwin")
about.run()
about.destroy()
builder = Gtk.Builder()
builder.add_from_file("v0.glade")
builder.connect_signals(Handler())
main = builder.get_object("signinwin")
main.show_all()
Gtk.main()

I can't tell you what exactly what the error is, but it might be that you assigned the wrong signals in Glade. 我无法告诉您错误的确切含义，但可能是您在Glade中分配了错误的信号。 I switched the close event from GtkDialog --> close to GtkDialog --> response . 我从GtkDialog->接近 GtkDialog->响应切换了close事件。 It probably is also better to only get the AboutDialog when you need it, so I put it into its own class. 最好只在需要时获取AboutDialog，所以我将其放在自己的类中。 I am also a beginner, but the code should work now: 我也是一个初学者，但是代码现在应该可以工作：
#!/usr/bin/python
from gi.repository import Gtk
class AboutDialog:
def __init__(self):
self.builder = Gtk.Builder()
self.builder.add_objects_from_file("v0.glade", ("aboutwin", ""))
self.ab = self.builder.get_object("aboutwin")
self.builder.connect_signals(self)
def on_aboutdialog_response(self, widget, signal):
print("About close with button or (x)")
self.ab.hide()
def run(self):
self.ab.run()
class MainHandler(Gtk.Window):
def on_delete_window(self, widget, signal):
print("Main window closed")
Gtk.main_quit()
def on_about_pressed(self, button):
print("Run About Dialog")
about = AboutDialog()
about.run()
def main():
builder = Gtk.Builder()
builder.add_objects_from_file("v0.glade", ("signinwin", "") )
builder.connect_signals(MainHandler())
main = builder.get_object("signinwin")
main.show_all()
Gtk.main()
if __name__ == "__main__":
main()
