466 \class QInputDialog -

467 \brief The QInputDialog class provides a simple convenience dialog to get a -

468 single value from the user. -

469 \ingroup standard-dialogs -

470 \inmodule QtWidgets -

471 -

472 The input value can be a string, a number or an item from a list. A label -

473 must be set to tell the user what they should enter. -

474 -

475 Five static convenience functions are provided: getText(), getMultiLineText(), -

476 getInt(), getDouble(), and getItem(). All the functions can be used in a similar way, -

477 for example: -
