Events

ValueChangeCompleted

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

Declaration
public event EventHandler<SFCircularPointer.PointerValueChangedEventArgs> ValueChangeCompleted
Event Type
Type
System.EventHandler<SFCircularPointer.PointerValueChangedEventArgs>
Remarks

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

ValueChangeStarted

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

Declaration
public event EventHandler<SFCircularPointer.PointerValueChangedEventArgs> ValueChangeStarted
Event Type
Type
System.EventHandler<SFCircularPointer.PointerValueChangedEventArgs>
Remarks

This event shouldn't be used to update the pointer value (use PointerPositionChanged 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.

ValueChanging

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

Declaration
public event EventHandler<SFCircularPointer.PointerValueChangingEventArgs> ValueChanging
Event Type
Type
System.EventHandler<SFCircularPointer.PointerValueChangingEventArgs>
Remarks

This event shouldn't be used to update the pointer value (use PointerPositionChanged event for that), but rather it will show the old value and new value of the pointer.
