[Glade-users] Possible bug with File-chooser dialog?

[alfraealba at googlemail.com (alsaf)]

I am just new to glade so not sure if this is a bug or a
misunderstanding on my part as I have an alternative way of doing what I
want working.

To give a bit of a background, I am converting GTK hardcoded code in my
python program to glade files. One part of the GTK code in my program is
a dialog which has a text entry and a button beside it when clicked
opens a filechooser dialog which populates the text entry with selected
folder. The glade file is as follows:

File: options.glade

************************************************************

The test file written in python is as follows:

options.py
************************************************************
import sys
import gtk
  
class template:
        def mp3_button_cp(self, widget, data=None):
                self.mp3_fcd.set_current_folder("/")
                response = self.mp3_fcd.run()
                print "this is response " + str (response)
                if response == 1:
                        self.mp3_entry.set_text(self.mp3_fcd.get_filename())
                self.mp3_fcd.destroy()  
        
        def response_cb(self, widget, response_id):
                print "This is response_id" + str(response_id)
                self.dialog.destroy()

        def __init__(self):
                builder = gtk.Builder()
                builder.add_from_file("options.glade") 
                self.dialog = builder.get_object("dialog")
                self.mp3_fcd = builder.get_object("mp3_fcd")    
                self.mp3_entry = builder.get_object("mp3_entry")
                builder.connect_signals(self)
                self.dialog.show()

if __name__ == "__main__":
        editor = template()
        gtk.main()
**************************************************************

The program works properly until you click on Browse... button again
where a blank filechooser dialog button appears and the following error
messages appear in console:


*****************************************************
options.py:6: GtkWarning: gtk_file_chooser_set_current_folder_file:
assertion `GTK_IS_FILE_CHOOSER (chooser)' failed
  self.mp3_fcd.set_current_folder("/")

  response = self.mp3_fcd.run()
options.py:7: GtkWarning: gtk_widget_map: assertion `GTK_IS_WIDGET

  response = self.mp3_fcd.run()
options.py:7: GtkWarning: _gtk_file_chooser_embed_initial_focus:

this is response -1
options.py:11: GtkWarning: gtk_widget_unmap: assertion `GTK_IS_WIDGET
(widget)' failed
  self.mp3_fcd.destroy()
*****************************************************

I have amended the code for the following and the behaviour still
occurs:

* create a new gtk.builder (calling it builder2) object solely for
mp3_fcd glade object
* moved mp3cp_fcd creation in mp3_button_cp callback function
* create a gtk.builder variable and mp3cp_fcd in mp3_button_cp function

I then proceeded to create a new glade file with just the fildechooser
dialog in it and obviously amending the code to create a new gtk.builder
object for it. I then ran the program and it worked properly with no
errors.

Is this a bug or has certain dialog got to be in separate files?
