473 | \brief The QInputDialog class provides a simple convenience dialog to get a | - | ||||||
474 | single value from the user. | - | ||||||
475 | \ingroup standard-dialogs | - | ||||||
476 | \inmodule QtWidgets | - | ||||||
477 | - | |||||||
478 | The input value can be a string, a number or an item from a list. A label | - | ||||||
479 | must be set to tell the user what they should enter. | - | ||||||
480 | - | |||||||
481 | Five static convenience functions are provided: getText(), getMultiLineText(), | - | ||||||
482 | getInt(), getDouble(), and getItem(). All the functions can be used in a similar way, | - | ||||||
483 | for example: | - | ||||||
484 | - | |||||||
485 | \snippet dialogs/standarddialogs/dialog.cpp 3 | - | ||||||

487 | The \c ok variable is set to true if the user clicks \uicontrol OK; otherwise, it | - | ||||||
488 | is set to false. | - | ||||||
