cursor position in filename entry of gtkfilechooserdialog

[Ferdinand Ramirez <ramirez ferdinand yahoo com>]

If I set the filename using gtk_file_chooser_set_current_name from a callback method for key-press-event, the 
filename shows up in the text entry box, but the cursor position is at 0 once the filename has been set. How 
do I set the cursor position to be at the end of the string I set as the filename?

Thanks,
