Parameters
renderContextWGL render context handle.

Member Function Documentation

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

Gets the pointer to a GL function.

Parameters
functionNameName 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
deviceContextThe 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
deviceContextHandleThe 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.
