Detailed Description

Class that represents the WGL context.

Since

Kanzi 3.9.7

Constructor & Destructor Documentation

kanzi::win32::WGLContext::WGLContext ( Win32DeviceContext &  deviceContext, int  formatID  )

explicit

Constructor.

Parameters

deviceContext	The device context for which to create the WGL context.
formatID	The graphics format ID with which to select the pixel format. To select the default pixel format, use 0.

kanzi::win32::WGLContext::WGLContext ( HDC  deviceContextHandle )

explicit

Constructor.

Parameters

deviceContextHandle

The native device context for which to create the WGL context.

kanzi::win32::WGLContext::WGLContext ( HGLRC  renderContext )

explicit

Constructor.

Parameters

renderContext

WGL render context handle.

Member Function Documentation

static PROC kanzi::win32::WGLContext::getProcAddress ( const char *  functionName )

staticnoexcept

Gets the pointer to a GL function.

Parameters

functionName

Name of the GL function for which to get the pointer.

Returns

Pointer to the function. If the function is not found, null.

bool kanzi::win32::WGLContext::makeCurrent ( const Win32DeviceContext &  deviceContext )

noexcept

Activates WGL context for the current thread.

Parameters

deviceContext

The device context for which to activate the current thread.

Returns

On success, true, otherwise false.

bool kanzi::win32::WGLContext::makeCurrent ( HDC  deviceContextHandle )

noexcept

Activates the WGL context for the current thread.

Parameters

deviceContextHandle

The native device context for which to activate the current thread.

Returns

On success, true, otherwise false.

bool kanzi::win32::WGLContext::releaseCurrent ( )

noexcept

Deactivates the WGL context for the current thread.

Returns

On success, true, otherwise false.

KZ_NO_DISCARD HGLRC kanzi::win32::WGLContext::getNativeHandle ( ) const

noexcept

Gets the WGL render context handle.

Returns

The WGL render context handle.
