Re: [gtkmm] Good example of a Gtk::FileSelection that supports multpile selecting

[Matthew Walton <mxw00u cs nott ac uk>]

This isn't difficult...

Enable multiple selection on your Gtk::FileSelection by calling

fileselection.set_select_multiple(true);

Then to retrieve the list of selected files, use the

Glib::ArrayHandle<std::string> Gtk::FileSelection::get_selections()
const

method - for example:

void on_fileselection_ok() {
  std::list<std::string> selectedfiles;
  selectedfiles = fileselection.get_selections();
  // do something with selectedfiles list here
}

If you're still stuck, check out the towel-gtk2 module from Towel CVS
http://towel.sf.net (or use the SourceForge CVS browser) and have a look
in gui-playlist.cc, that uses a multiselect fileselection widget to add
files to the playlist. For the time being, at least.
