例子

一

代码：

#!/usr/bin/env python3# Created by xiaosanyu at 16/7/7# section 027TITLE = "Expander"DESCRIPTION = """A Gtk.Expander allows the user to hide or show its child by clicking onan expander triangle similar to the triangles used in a Gtk.TreeView."""import gigi.require_version("Gtk", "3.0")from gi.repository import Gtkclass ExpanderWindow(Gtk.Window):    def __init__(self):        Gtk.Window.__init__(self, title="Expander Example")        self.set_size_request(250, 200)        self.box = Gtk.VBox()        expander = Gtk.Expander.new("Expander")        expander.set_expanded(True)        expander.connect("activate", self.callback)        label = Gtk.Label("label")        expander.add(label)        self.box.pack_start(expander, False, False, 0)        self.add(self.box)    @staticmethod    def callback(widget):        if widget.get_expanded():            print("unexpanded")        else:            print("expanded")def main():    win = ExpanderWindow()    win.connect("delete-event", Gtk.main_quit)    win.show_all()    Gtk.main()if __name__ == "__main__":    main()

代码解析

expander = Gtk.Expander.new("Expander")expander.set_expanded(True)

创建一个Gtk.Expander，设置模式为展开

label = Gtk.Label("label")expander.add(label)

创建一个Label，添加到expander容器中

二

使用Gtk.Builder来创建Expander

代码：

#!/usr/bin/env python3# Created by xiaosanyu at 16/7/7# section 028TITLE = "Expander_created_by_ui"DESCRIPTION = ""import gigi.require_version("Gtk", "3.0")from gi.repository import GtkUIINFO = """<?xml version="1.0" encoding="UTF-8"?><interface>    <!-- interface-requires gtk+ 3.0 -->    <object class="GtkWindow" id="window1">        <property name="can_focus">False</property>        <signal name="delete-event" handler="onDeleteWindow" swapped="no"/>        <child>            <object class="GtkExpander">                <child type="label">                    <object class="GtkLabel" id="expander-label">                    <property name="label">expander</property>                    </object>                </child>                <child>                    <object class="GtkEntry" id="expander-content" />                </child>            </object>        </child>    </object></interface>"""class Handler:    @staticmethod    def onDeleteWindow(*args):        Gtk.main_quit(*args)def main():    builder = Gtk.Builder()    builder.add_from_string(UIINFO)    builder.connect_signals(Handler())    window = builder.get_object("window1")    window.show_all()    Gtk.main()if __name__ == "__main__":    main()
