Device Class

This .NET class wraps the OdGsDevice class. The device is the abstract representation of the GUI window where the drawing is displayed. In addition, it responds to operating system notifications, such as window resizing, that are forwarded by the graphics system client. For more information, see Working with Graphic Devices.

Copy

public abstract class Device : RXObject

Public MustInherit Class Device
        Inherits RXObject

public ref class Device abstract : public RXObject

[<AbstractClassAttribute>]
type Device = 
    class

The Device type exposes the following members.

Constructors

	Name	Description
	Device	Default constructor for the Device class. Creates a graphics device based on an internal pointer to the wrapped C++ object.
	Device(IntPtr, Boolean)	Initializes a new instance of the Device class

Methods

	Name	Description
	Add	Adds a graphics view where drawing is drawn. Returns true if the view was successfully added to the device.
	Clone	(Inherited from RXObject)
	CompareTo	(Inherited from RXObject)
	CopyFrom	(Inherited from RXObject)
	CreateModel	Creates a new model object, and associates it with this device.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject)
	CreateView	Creates a new view and associates it with this device.
	CreateView(ClientViewInfo)	Creates a new view based on the client view information and associates it with this device.
	CreateView(ClientViewInfo, Boolean)	Creates a new view based on the client view information and associates it with this device.
	DeleteUnmanagedObject	(Overrides RXObjectDeleteUnmanagedObject)
	Dispose	(Inherited from DisposableWrapper)
	Dispose(Boolean)	(Inherited from DisposableWrapper)
	Equals	(Inherited from DisposableWrapper)
	Erase(Int32)	Erases a view by the specified index.
	Erase(View)	Erases the specified view object.
	EraseAll	Erases all views associated with this device.
	Finalize	(Inherited from DisposableWrapper)
	GetHashCode	(Inherited from DisposableWrapper)
	GetImpObj
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject)
	GetRXClass	(Inherited from RXObject)
	GetSize	Retrieves the size of the device.
	GetSizeExt	Retrieves the extents that represent dimensions of the device.
	GetSizeRect	Retrieves the rectangle that represents dimensions of the device.
	GetSnapshot	Performs a snapshot of the device's current graphics status.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject)
	InsertView	Inserts the specified view object to the specified position (defined by the viewIndex parameter) in this device.
	Invalidate	This method is used to signal that the entire display area is invalid and needs to be refreshed.
	Invalidate(Rectangle)	This method is used to signal that the specified display area is invalid area needs to be refreshed.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject)
	OnDisplayChange	Causes this device to accept new screen resolution and color depth whenever an operating system changes these parameters.
	OnRealizeBackgroundPalette	Causes this device to realize its palette in the background. This method is usually called when the GUI window loses focus.
	OnRealizeForegroundPalette	Causes this device to realize its palette in the foreground. This method is usually called when the GUI window loses focus.
	OnSize(Extents2d)
	OnSize(Rectangle)
	OnSize(Size)
	QueryX	(Inherited from RXObject)
	SetLogicalPalette	Sets the logical color palette to be used by this device. The set palette can later be used for setting indexed colors.
	ToString	Returns a string that represents the current object. (Inherited from Object)
	Update	Sends the "update" message to all owned views and forces to display the correct, up to date picture.
	Update(Rectangle)	Sends the "update" message to all owned views and forces to display the correct, up to date picture.
	ViewAt	Retrieves a view by the specified index.
	X	(Inherited from RXObject)
