Method Detail

glGetString

java.lang.String glGetString(int name)

The glGetString function returns a string describing the current OpenGL connection.

Parameters:

name - One of the following symbolic constants.

Returns:

The glGetString function returns a pointer to a static string describing some aspect of the current OpenGL connection.

wglCreateContext

WinDef.HGLRC wglCreateContext(WinDef.HDC windowDC)

The wglCreateContext function creates a new OpenGL rendering context, which is suitable for drawing on the device referenced by hdc. The rendering context has the same pixel format as the device context.

Parameters:

windowDC - Handle to a device context for which the function creates a suitable OpenGL rendering context.

Returns:

handle to an OpenGL rendering context

wglGetCurrentContext

WinDef.HGLRC wglGetCurrentContext()

The wglGetCurrentContext function obtains a handle to the current OpenGL rendering context of the calling thread.

Returns:

If the calling thread has a current OpenGL rendering context, wglGetCurrentContext returns a handle to that rendering context. Otherwise, the return value is NULL.

wglMakeCurrent

boolean wglMakeCurrent(WinDef.HDC windowDC,
                       WinDef.HGLRC hglrc)

The wglMakeCurrent function makes a specified OpenGL rendering context the calling thread's current rendering context. All subsequent OpenGL calls made by the thread are drawn on the device identified by hdc.

Parameters:

windowDC - Handle to a device context. Subsequent OpenGL calls made by the calling thread are drawn on the device identified by hdc.

hglrc - Handle to an OpenGL rendering context that the function sets as the calling thread's rendering context.

Returns:

true if successful

wglDeleteContext

boolean wglDeleteContext(WinDef.HGLRC hglrc)

The wglDeleteContext function deletes a specified OpenGL rendering context.

Parameters:

hglrc - Handle to an OpenGL rendering context that the function will delete.

Returns:

true if successful

wglGetProcAddress

Pointer wglGetProcAddress(java.lang.String lpszProc)

The wglGetProcAddress function returns the address of an OpenGL extension function for use with the current OpenGL rendering context.

Parameters:

lpszProc - Points to a null-terminated string that is the name of the extension function. The name of the extension function must be identical to a corresponding function implemented by OpenGL.

Returns:

When the function succeeds, the return value is the address of the extension function.
