我有一个在PyGTK中使用gtk.MessageDialog创建提示的函数。我怎样才能访问预定义的按钮?或者我需要手动构建一个gtk.Dialog?我不愿意,因为MessageDialog是一个便利功能。
功能:
def gtkPrompt(self, name):
# Create new GTK dialog with all the fixings
prompt = gtk.MessageDialog(None, 0, gtk.MESSAGE_QUESTION, gtk.BUTTONS_OK_CANCEL, name)
# Set title of dialog
prompt.set_title("Prompt")
# Create and add entry box to dialog
entry = gtk.Entry()
prompt.vbox.add(entry)
# Show all widgets in prompt
prompt.show_all()
# Run dialog until user clicks OK or Cancel
if prompt.run() == gtk.RESPONSE_CANCEL:
# User cancelled dialog
rval = False
else:
# User clicked OK, grab text from entry box
rval = entry.get_text()
# Destory prompt
prompt.destroy()
# Give the good (or bad) news
return rval

您可以使用get_children()转到“确定”按钮:
def yesNoDialog(window, message, default=False):
dialog=gtk.MessageDialog(window, gtk.DIALOG_MODAL |
gtk.DIALOG_DESTROY_WITH_PARENT,
gtk.MESSAGE_QUESTION,
gtk.BUTTONS_YES_NO, message)
if default:
h_button_box=dialog.vbox.get_children()[1]
yes_button=h_button_box.get_children()[0]
yes_button.grab_default()
response=dialog.run()
dialog.destroy()
if response==gtk.RESPONSE_YES:
return True
else:
return False

gtk.MessageDialog
是gtk.Dialog
的子类。 gtk.Dialog
个对象将其按钮存储在gtk.HBox
属性下的action_area
。
在代码中:
> prompt.action_area.get_children()
[<gtk.Button object at 0x18c0aa0 (GtkButton at 0x130e990)>, <gtk.Button object at 0x18c0af0 (GtkButton at 0x130e8d0)>]

从2.22开始,您可以使用get_widget_for_response()方法。例如:
cancelButton = dialog.get_widget_for_response(response_id=gtk.RESPONSE_CANCEL)
