Since

5.7

The Dial is similar to a traditional dial knob that is found on devices such as stereos or industrial equipment. It allows the user to specify a value within a range.

The value of the dial is set with the \l value property. The range is set with the \l from and \l to properties. To enable or disable wrapping, use the \l wrap property.

The dial can be manipulated with a keyboard. It supports the following actions:

\table \header

• {Action}
• {Key} \row
• Decrease \l value by \l stepSize
• Qt.Key_Left \row
• Decrease \l value by \l stepSize
• Qt.Key_Down \row
• Set \l value to \l from
• Qt.Key_Home \row
• Increase \l value by \l stepSize
• Qt.Key_Right \row
• Increase \l value by \l stepSize
• Qt.Key_Up \row
• Set \l value to \l to
• Qt.Key_End \endtable

QtQuick.Controls 2.2 (Qt 5.9) \qmlsignal QtQuick.Controls::Dial::moved()

This signal is emitted when the dial has been interactively moved by the user by either touch, mouse, or keys.

\qmlsignal QtQuick.Controls::Dial::wrapped(Dial.WrapDirection direction)

Since

6.6

This signal is emitted when the dial wraps around, i.e. goes beyond its maximum value to its minimum value, or vice versa. It is only emitted when \l wrap is true. The direction argument specifies the direction of the full rotation and will be one of the following arguments:

\value Dial.Clockwise The dial wrapped in clockwise direction. \value Dial.CounterClockwise The dial wrapped in counterclockwise direction.
