Initializes a new instance of the ExternalDrawable class.
Overload List
| Name | Description | |
|---|---|---|
| Public method | ExternalDrawable() | Initializes a new instance of the ExternalDrawable class that is not attached to a drawing surface. |
| Public method | ExternalDrawable(System.IntPtr param1, System.IntPtr param2) | Initializes a new instance of the ExternalDrawable class with the given parameters. |
| Public method | ExternalDrawable(System.IntPtr param1, System.IntPtr param2, System.IntPtr param3) | Initializes a new instance of the ExternalDrawable class with the given parameters. |
ExternalDrawable()
Initializes a new instance of the ExternalDrawable class that is not attached to a drawing surface.Syntax
public ExternalDrawable ()Remarks
This constructor creates a drawable that is not attached to a drawing surface and nothing will be visible until one has been attached by calling Attach with a valid OpenGL context and device handle.
ExternalDrawable(System.IntPtr param1, System.IntPtr param2)
Initializes a new instance of the ExternalDrawable class with the given parameters.Syntax
public ExternalDrawable (
System.IntPtr param1,
System.IntPtr param2
)Parameters
The OpenGL context.
The OpenGL device handle.
Remarks
On Windows, param1 should be the handle to the OpenGL context (of type HGLRC), and param2 should be the handle to the OpenGL device context (of type HDC).
On Linux when using OpenGL, param1 is the OpenGL context (of type GLXContext) and param2 is the OpenGL drawable ID (of type GLXDrawble, cast to a void pointer).
On Linux when using OpenGL ES, param1 is the OpenGL ES context (of type EGLContext) and param2 is the OpenGL drawable ID (of type EGLDrawble, cast to a void pointer).
ExternalDrawable(System.IntPtr param1, System.IntPtr param2, System.IntPtr param3)
Initializes a new instance of the ExternalDrawable class with the given parameters.Syntax
public ExternalDrawable (
System.IntPtr param1,
System.IntPtr param2,
System.IntPtr param3
)Parameters
The OpenGL context.
The OpenGL device handle.
The OpenGL secondary context.
Remarks
On Windows, param1 should be the handle to the OpenGL context (of type HGLRC), and param2 should be the handle to the OpenGL device context (of type HDC).
On Linux, when using OpenGL, param1 is the OpenGL context (of type GLXContext) and param2 is the OpenGL drawable ID (of type GLXDrawble, cast to a void pointer).
On Linux, when using OpenGL ES, param1 is the OpenGL context (of type EGLContext) and param2 is the OpenGL drawable ID (of type EGLSurface, cast to a void pointer).
param3 is a handle to a secondary OpenGL context that will be used for asynchronous resource management. param3 has the same type as param1 and resources between these two contexts should be shared.
