482 | \brief The QInputDialog class provides a simple convenience dialog to get a |
483 | single value from the user. |
484 | \ingroup standard-dialogs |
485 | \inmodule QtWidgets |
486 | |
487 | The input value can be a string, a number or an item from a list. A label |
488 | must be set to tell the user what they should enter. |
489 | |
490 | Five static convenience functions are provided: getText(), getMultiLineText(), |
491 | getInt(), getDouble(), and getItem(). All the functions can be used in a similar way, |
492 | for example: |
493 | |
494 | \snippet dialogs/standarddialogs/dialog.cpp 3 |
495 | |
496 | The \c ok variable is set to true if the user clicks \uicontrol OK; otherwise, it |
497 | is set to false. |
