Problem This is in response to the comments of Wim Stockman from Belgium with regards to opening multiple files with GtkFileChooser.
He pointed out that we can also open multiple files with GtkFileChooser.
So here is a complete sample code of allowing multiple files selection with GtkFileChooserDialog as shown below. Note that just like in the explorer, you can select multiple files with shift click or ctrl-click.
