// Puts up a QListWidget in a box allowing selections from a list of strings.
// Similar to QTSelectItems.H but in Qt4 speak.
// This must always be used as a modal dialog, since the address of the vector
// holding the selections is kept, and this must be in scope when it is filled.
// It is filled when either the ok or cancel buttons are pressed.
