qreal QQuickDial::endAngle | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::endAngle
This property holds the end angle of the dial in degrees.
This is the \l angle the dial will have for its maximum value, i.e. \l to. The \l endAngle has to be bigger than the \l startAngle, smaller than 720 and smaller or equal than the \l startAngle + 360 degrees.

\qmlmethod void QtQuick.Controls::Dial::increase()
Increases the value by \l stepSize, or 0.1
if stepSize is not defined.
Definition at line 852 of file qquickdial.cpp.
QQuickDial::InputMode QQuickDial::inputMode | ( | ) | const |
This property holds the input mode.
inputMode
The default value is Dial.Circular
.
Definition at line 697 of file qquickdial.cpp.
bool QQuickDial::isPressed | ( | ) | const |
\qmlproperty bool QtQuick.Controls::Dial::pressed
This property holds whether the dial is pressed.
The dial will be pressed when either the mouse is pressed over it, or a key such as Qt.Key_Left
is held down. If you'd prefer not to have the dial be pressed upon key presses (due to styling reasons, for example), you can use the \l {Keys}{Keys attached property}:
This will result in pressed only being true
upon mouse presses.
Definition at line 765 of file qquickdial.cpp.
This event handler can be reimplemented in a subclass to receive key press events for an item.
The event information is provided by the event parameter.
\input item.qdocinc accepting-events

Definition at line 915 of file qquickdial.cpp.
bool QQuickDial::live | ( | ) | const |
This property holds whether the dial provides live updates for the \l value property while the handle is dragged.
The default value is true

This event handler can be reimplemented in a subclass to receive mouse press events for an item.
The event information is provided by the event parameter.
In order to receive mouse press events, \l acceptedMouseButtons() must return the relevant mouse button.
\input item.qdocinc accepting-events
Reimplemented from QQuickControl.
Definition at line 921 of file qquickdial.cpp.
qreal QQuickDial::position | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::position \readonly
This property holds the logical position of the handle.
The position is expressed as a fraction of the control's angle range (the range within which the handle can be moved) in the range {0.0
- 1.0}.

QQuickDial::SnapMode QQuickDial::snapMode | ( | ) | const |
\qmlproperty enumeration QtQuick.Controls::Dial::snapMode
This property holds the snap mode.
The snap mode works with the \l stepSize to allow the handle to snap to certain points along the dial.
Possible values: \value Dial.NoSnap The dial does not snap (default). \value Dial.SnapAlways The dial snaps while the handle is dragged. \value Dial.SnapOnRelease The dial does not snap while being dragged, but only after the handle is released.
Definition at line 671 of file qquickdial.cpp.

signal |
qreal QQuickDial::startAngle | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::startAngle
This property holds the starting angle of the dial in degrees.
This is the \l angle the dial will have for its minimum value, i.e. \l from. The \l startAngle has to be smaller than the \l endAngle, larger than -360 and larger or equal to the \l endAngle - 360 degrees.
Definition at line 546 of file qquickdial.cpp.
qreal QQuickDial::stepSize | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::stepSize
This property holds the step size.
The step size determines the amount by which the dial's value is increased and decreased when interacted with via the keyboard. For example, a step size of 0.2
, will result in the dial's value increasing and decreasing in increments of 0.2
.
The step size is only respected for touch and mouse interaction when \l snapMode is set to a value other than Dial.NoSnap
.
The default value is 0.0
, which results in an effective step size of 0.1
for keyboard interaction.

qreal QQuickDial::to | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::to

qreal QQuickDial::value | ( | ) | const |
\qmlproperty real QtQuick.Controls::Dial::value
This property holds the value in the range from

.
Definition at line 444 of file qquickdial.cpp.
|
signal |
bool QQuickDial::wrap | ( | ) | const |
\qmlproperty bool QtQuick.Controls::Dial::wrap
This property holds whether the dial wraps when dragged.
For example, when this property is set to true
, dragging the dial past the \l to position will result in the handle being positioned at the \l from position, and vice versa:
When this property is false
, it's not possible to drag the dial across the from and to values.
The default value is false
.
