file selection

[srinivas <srinivas comodo com>]

hi;

i used 

filew = gtk_file_selection_new ("Folder Selection");
gtk_file_selection_set_filename (GTK_FILE_SELECTION (filew), "***.png");
gtk_file_selection_get_filename (GTK_FILE_SELECTION (filew));
gtk_widget_show(filew);

to select and display file/folder list, i can able to display widget,
but i can't able to select the file. no buttons in the widget as delete
file, rename, cancel and ok are not working. what else i have to include
in my pgm to get that functionality.

thanks;

vasu.
