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,所以我想要它包装而不会使对话格宽阔.
出于某种原因,我无法找到让GTK允许这种情况发生的方法.我甚至找不到在对话框上设置最大宽度的方法,这将是很好的.
这是我的意思的一个运行的例子：
#!/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,(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()
解决方法
我解决了这个问题(除了将换行设置为True),将Gtk.Label放入Gtk.Table中,使用FILL和SHRINK标志并为标签设置固定宽度.像这样的东西：
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)
label.set_size_request(250,-1) # 250 or whatever width you want. -1 to keep height automatic
table = Gtk.Table(1,1,False)
table.attach(label,Gtk.AttachOptions.SHRINK | Gtk.AttachOptions.FILL)
这应该够了吧
