把一个标签放在python gtk文本条目旁边

Question

所以我试图用python GTK构建一个非常基本的GUI，但我很快就感到沮丧。如何将我的标签放在我的文字输入旁边？我怎样才能让这个项目更小？按钮更小？我将不得不添加更多条目，并一次性全部处理这些信息，而且我不一定需要它们填满窗口......谢谢。

    #Another Callback 
    def destroy(self, widget, data=None): 
     gtk.main_quit() 

    def __init__(self): 

     self.fix = gtk.Fixed()

     vbox.show()

     self.window.connect("delete_event", self.delete_event) 

     #Connect the "destroy" event to a signal handler 
     #Occurs with gtk_widget_destroy() or False in delete_event

     #The final step is to display this newly created widget. 
     vbox.pack_start(self.button, False, False, 00) 
     self.button.show() 

     #And the window 
     self.window.show()

     #and waits for an event to occur 
     gtk.main()

#If the program is run, create a gui instance and show it 
if __name__ == "__main__": 
    hello = text_box() 
    hello.main()

尝试使用Table，并使用表添加到窗口：

table=Gtk.Table(1,4,True) 
table.attach(label,0,1,0,1) 
table.attach(entry,1,3,0,1) 
table.attach(button,3,4,0,1) 
window.add(table) 
window.show_all() 

这显示文本框旁边的标签，与按钮旁边它

您可以设置hexpand和vexpand属性为False，halign和valign属性为Gtk.Align.FILL以外的其他属性，以便这些小部件不占用最大值空间。
