我正在尝试创建一个带有标签的不可调整大小的对话框。这个标签有很多文字,所以我希望它在不使对话框变得荒谬的情况下换行。
出于某种原因,我不知道如何让 GTK 允许这种情况发生。我什至找不到在对话框上设置最大宽度的方法,这很好。
这是我的意思的一个运行示例:
#!/usr/bin/env python
#-*- coding:utf-8 -*-
from gi.repository import Gtk
class DialogExample(Gtk.Dialog):
def __init__(self, parent):
Gtk.Dialog.__init__(self, "My Dialog", parent, 0,
(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL,
Gtk.STOCK_OK, Gtk.ResponseType.OK))
self.set_default_size(150, 100)
self.set_resizable(False)
label = Gtk.Label("This is a dialog to display additional information, with a bunch of text in it just to make sure it will wrap enough for demonstration purposes")
label.set_line_wrap(True)
box = self.get_content_area()
box.add(label)
self.show_all()
class DialogWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Dialog Example")
self.set_default_size(250, 200)
button = Gtk.Button("Open dialog")
button.connect("clicked", self.on_button_clicked)
self.add(button)
def on_button_clicked(self, widget):
dialog = DialogExample(self)
response = dialog.run()
if response == Gtk.ResponseType.OK:
print "The OK button was clicked"
elif response == Gtk.ResponseType.CANCEL:
print "The Cancel button was clicked"
dialog.destroy()
win = DialogWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
