// -=- ConnectingDialog.h

// ConnectingDialog instances are used to display a status dialog while a
// connection attempt is in progress.  The connection attempt is performed
// in a background thread by the ConnectingDialog, to allow the status dialog
// to remain interactive.  If the dialog is cancelled then it will close and
// the connection dialog will eventually tidy itself up.
