作为一个新手，我正在尝试使用 Glade 和 python 创建一个基本的主题安装程序。一切正常，但我无法在任何地方找到如何为 gtkFileChooserButton 使用 get_filename() 方法。我的 Glade 文件看起来像这样。

<?xml version="1.0"?>
<interface>
  <requires lib="gtk+" version="2.16"/>
  <!-- interface-naming-policy project-wide -->

        <child>
          <object class="GtkFileChooserButton" id="DD">

`

Python代码是：

import sys
try:  
import pygtk  
pygtk.require("2.0")  
except:  
pass  
try:  
import gtk   
except:  
print("GTK Not Availible")
sys.exit(1)


class workplz(object):


def __init__( self ):
    builder = gtk.Builder()
    builder.add_from_file("heme.glade")
    builder.connect_signals({"on_main_destroy" : self.quit, "on_Add_clicked" : self.add, "on_Quit_clicked" : self.quit})
    self._window = builder.get_object("main")
    self._window.show()     

def add(self, widget):
    target=DD.get_filename()
    print target


def quit(self, widget):
    sys.exit(0)


if __name__ == "__main__":
    wine = workplz()
    gtk.main()

什么是正确的做法？？？

我相信如果您从构建器获取 GtkFileChooserButton 对象并将对它的引用保存为类成员，您可以在信号处理程序workplz中查询它。add看看下面的脚本是否适合你：

class workplz(object):
    def __init__( self ):
        builder = gtk.Builder()
        builder.add_from_file("heme.glade")
        builder.connect_signals({"on_main_destroy" : self.quit, "on_Add_clicked" : self.add, "on_Quit_clicked" : self.quit})

        # get GtkFileChooserButton object 
        self.DD = builder.get_object('DD')

        self._window = builder.get_object("main")
        self._window.show()     

    def add(self, widget):
        target = self.DD.get_filename()
        print target

    def quit(self, widget):
        sys.exit(0)

希望这会有所帮助，问候
