System.Double

Value

Gets or sets the Value that decides the position of the CircularPointer in the CircularScale.

Declaration
public double Value { get; set; }
Property Value
Type Description
System.Double

double
Remarks

Value property is one of the most important property. Based on the Value property pointer has been positioned on the CircularScale. Value should resides between the start and end value of the scale. If the value of this property is less than StartValue of the CircularScale, then the StartValue of the CircularScale is set to the Value of the pointer. Similarly EndValue of the CircularScale is set to the Value of the pointer when Value is greater that EndValue of the scale.

Methods

OnApplyTemplate()

Declaration
public override void OnApplyTemplate()

OnMouseDown(MouseButtonEventArgs)

Invoked when the MouseDown attached event reaches an element in its route that is derived from this class. Implement this method to add class handling for this event.

Declaration
protected override void OnMouseDown(MouseButtonEventArgs e)
Parameters
Type Name Description
System.Windows.Input.MouseButtonEventArgs e

The System.Windows.Input.MouseButtonEventArgs that contains the event data.

OnMouseUp(MouseButtonEventArgs)

Invoked when the MouseUp attached event reaches an element in its route that is derived from this class. Implement this method to add class handling for this event.

Declaration
protected override void OnMouseUp(MouseButtonEventArgs e)
Parameters
Type Name Description
System.Windows.Input.MouseButtonEventArgs e

The System.Windows.Input.MouseButtonEventArgs that contains the event data.

Events

PointerPositionChanged

Occurs when pointer position is changed

Declaration
public event CircularPointer.PointerPositionChangedEventHandler PointerPositionChanged
Event Type
Type Description
CircularPointer.PointerPositionChangedEventHandler

ValueChangeCompleted

Called when the user is done selecting a new value of the pointer by dragging.

Declaration
public event EventHandler<ValueChangedEventArgs> ValueChangeCompleted
Event Type
Type Description
System.EventHandler<ValueChangedEventArgs>
Remarks

This event shouldn't be used to update the pointer value (use onValueChanged for that), but rather to notify the new value before when the user has completed selecting a new value by drag . ///

See Also

ValueChanged

Called during a drag when the user is selecting a new value for the pointer by dragging.

Declaration
public event EventHandler<ValueChangedEventArgs> ValueChanged
Event Type
Type Description
System.EventHandler<ValueChangedEventArgs>
Remarks

This event is used to know the pointer value changed, when the user change pointer value dynamically or changing pointer value by dragging.

See Also

ValueChangeStarted

Called when the user starts selecting a new value of pointer by dragging.

Declaration
public event EventHandler<ValueChangedEventArgs> ValueChangeStarted
Event Type
Type Description
System.EventHandler<ValueChangedEventArgs>
Remarks

This event shouldn't be used to update the pointer value (use ValueChanged event for that), but rather to be notified when the user has started selecting a new value by starting a drag. The value passed will be the last value that the pointer had before the change began.

See Also

ValueChanging

Called during a drag when the user is selecting before a new value for the pointer by dragging

Declaration
public event EventHandler<ValueChangingEventArgs> ValueChanging
Event Type
Type Description
System.EventHandler<ValueChangingEventArgs>
Remarks

This event shouldn't be used to update the pointer value (use ValueChanged event for that), but rather to know the new value before when the user has completed selecting a new value by drag.
