Syntax

public class ZoomState : ICloneable

Remarks

This class is used to store scale ranges in order to allow zooming out to prior scale range states. ZoomState objects are maintained in the ZoomStateStack collection. The ZoomState object holds a ScaleState object for each of the three axes; the XAxis, the YAxis, and the Y2Axis.

Constructors

ZoomState(GraphPane, ZoomState.StateType)

Construct a ZoomState object from the scale ranges settings contained in the specified GraphPane.

Declaration

public ZoomState(GraphPane pane, ZoomState.StateType type)

Parameters

Type	Name	Description
GraphPane	pane	The GraphPane from which to obtain the scale range values.
ZoomState.StateType	type	A ZoomState.StateType enumeration that indicates whether this saved state is from a pan or zoom.

ZoomState(ZoomState)

The Copy Constructor

Declaration

public ZoomState(ZoomState rhs)

Parameters

Type	Name	Description
ZoomState	rhs	The ZoomState object from which to copy

Properties

Type

Gets a ZoomState.StateType value indicating the type of action (zoom or pan) saved by this ZoomState.

Declaration

public ZoomState.StateType Type { get; }

Property Value

Type	Description
ZoomState.StateType

TypeString

Gets a string representing the type of adjustment that was made when this scale state was saved.

Declaration

public string TypeString { get; }

Property Value

Type	Description
String	A string representation for the state change type; typically "Pan", "Zoom", or "Scroll".

Methods

ApplyState(GraphPane)

Copy the properties from this ZoomState out to the specified GraphPane.

Declaration

public void ApplyState(GraphPane pane)

Parameters

Type	Name	Description
GraphPane	pane	The GraphPane to which the scale range properties should be copied.

Clone()

Typesafe, deep-copy clone method.

Declaration

public ZoomState Clone()

Returns

Type	Description
ZoomState	A new, independent copy of this class

IsChanged(GraphPane)

Determine if the state contained in this ZoomState object is different from the state of the specified GraphPane.

Declaration

public bool IsChanged(GraphPane pane)

Parameters

Type	Name	Description
GraphPane	pane	The GraphPane object with which to compare states.

Returns

Type	Description
Boolean	true if the states are different, false otherwise

Explicit Interface Implementations

ICloneable.Clone()

Implement the ICloneable interface in a typesafe manner by just calling the typed version of Clone()

Declaration

object ICloneable.Clone()

Returns

Type	Description
Object	A deep copy of this object
