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)

System.Object
  System.Drawing.BufferedGraphicsManager

public sealed class BufferedGraphicsManager

NameDescription
System_CAPS_pubpropertySystem_CAPS_staticCurrent

Gets the BufferedGraphicsContext for the current application domain.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

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.
BufferedGraphicsContext appDomainGraphicsContext = 
     BufferedGraphicsManager.Current;
