Constructor & Destructor Documentation

Create a new WGL window for the given eq::Window.

Version:
1.0
virtual eq::wgl::Window::~Window ( ) [virtual]

Destruct the WGL window.

Version:

Member Function Documentation

virtual int eq::wgl::Window::chooseWGLPixelFormat ( ) [virtual]

Choose a pixel format based on the window's attributes.

Uses the currently set DC (if any) and sets the chosen pixel format on it.

Returns:
a pixel format, or 0 if no pixel format was found.
Version:
1.0
virtual void eq::wgl::Window::configExit ( ) [virtual]
Version:
1.0

Implements eq::SystemWindow.

virtual bool eq::wgl::Window::configInit ( ) [virtual]

Initialize this window for the WGL window system.

This method first calls initWGLAffinityDC, then chooses a pixel format with chooseWGLPixelFormat, then creates a drawable using configInitWGLDrawable and finally creates the context using createWGLContext.

Returns:
true if the initialization was successful, false otherwise.
Version:
1.0

Implements eq::SystemWindow.

virtual bool eq::wgl::Window::configInitWGLDrawable ( int  pixelFormat) [virtual]

Initialize the window's drawable (pbuffer or window) and bind the WGL context.

Sets the window handle on success.

Parameters:
pixelFormatthe window's target pixel format.
Returns:
true if the drawable was created, false otherwise.
Version:
1.0
virtual bool eq::wgl::Window::configInitWGLPBuffer ( int  pixelFormat) [virtual]

Initialize the window with an off-screen WGL PBuffer.

Sets the window handle on success.

Parameters:
pixelFormatthe window's target pixel format.
Returns:
true if the drawable was created, false otherwise.
Version:
1.0
virtual bool eq::wgl::Window::configInitWGLWindow ( int  pixelFormat) [virtual]

Initialize the window with an on-screen Win32 window.

Sets the window handle on success.

Parameters:
pixelFormatthe window's target pixel format.
Returns:
true if the drawable was created, false otherwise.
Version:
1.0
virtual HGLRC eq::wgl::Window::createWGLContext ( ) [virtual]

Create a WGL context.

This method does not set the window's WGL context.

Returns:
the context, or 0 if context creation failed.
Version:
1.0
virtual HDC eq::wgl::Window::createWGLDisplayDC ( ) [virtual]

Create a device context for the display device of the window.

The returned device context has to be released using DeleteDC. The window's error message is set if an error occured.

Returns:
the DC, or 0 upon error.
Version:
1.0
virtual void eq::wgl::Window::destroyWGLContext ( HGLRC  context) [virtual]

Destroy the given WGL context.

Version:
1.0
