BufferedGraphicsManager Class

BufferedGraphicsManager Class

Provides access to the main buffered graphics context object for the application domain.


Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public sealed class BufferedGraphicsManager

The BufferedGraphicsManager type exposes the following members.

Public propertyStatic memberCurrentGets the BufferedGraphicsContext for the current application domain.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The BufferedGraphicsManager class allows you to implement custom double buffering for your graphics. Graphics that use double buffering can reduce or eliminate flicker that is caused by redrawing a display surface.

This class has one static property, Current, which returns the main BufferedGraphicsContext for the current application domain. The BufferedGraphicsContext class creates BufferedGraphics instances that can be used to draw buffered graphics.

The BufferedGraphics class has no public constructor and must be created by the BufferedGraphicsContext object for an application domain using its Allocate method. You can retrieve the BufferedGraphicsContext object for the current application domain from the static BufferedGraphicsManager.Current property.

For more information on double buffering, see Double Buffered Graphics, BufferedGraphics, and BufferedGraphicsContext.

The following code example demonstrates acquiring the BufferedGraphicsContext for the current application domain.

// Retrieves the BufferedGraphicsContext for the 
// current application domain.
