glade 3

用glade 3可以幫助我們把程式介面畫出來，存檔的副檔名雖為glade，但為xml格式。

細部的格式分libgrade 與 gtkbuilder ，此範例是用 libgrade。

libgrade

ui.glade (libgrade 的xml )

<glade-interface>
  <!-- interface-naming-policy project-wide -->
</glade-interface>

python 部份程式碼

#!/usr/bin/env python
import pygtk
import gtk
import gtk.glade

...

class Example():

    def __init__(self):
        self.ui_file=sys.path[0]+'/ui.glade'
        self.widgetTree=gtk.glade.XML(self.ui_file,'window1')
        dic={"on_exit_clicked":gtk.main_quit,\
             "on_window1_destroy":gtk.main_quit,\
             "on_XX_clicked":self.toXX,\
             "on_OO_clicked":self.toOO}
        self.widgetTree.signal_autoconnect(dic)

GTKBuilder

• GTKBuilder 為通用格式，libglade也可轉換為此格式

gtkbuilder 的xml格式

  <!-- interface-naming-policy project-wide -->
