void eq::GLXWindow::configExit (  )  [virtual]

De-initialize this OS window.

This function might be called on partially or uninitialized OS windows, and the implemenation has therefore be tolerant enough to handle this case.

Implements eq::OSWindow.

Definition at line 573 of file glXWindow.cpp.

References eq::GLWindow::configExitFBO(), EQINFO, eq::GLWindow::exitGLEW(), getGLXContext(), getXDisplay(), getXDrawable(), eq::Window::IATTR_HINT_DRAWABLE, leaveNVSwapBarrier(), eq::PBUFFER, setGLXContext(), and setXDrawable().

Here is the call graph for this function:

void eq::GLXWindow::makeCurrent (  )  const [virtual]

Make the OS window's rendering context and drawable current.

This function invalidates the pipe's make current cache. If this function is not called, Pipe::setCurrent() has to be called appropriately.

Reimplemented from eq::GLWindow.

void eq::GLXWindow::joinNVSwapBarrier ( const uint32_t  group,
const uint32_t  barrier 
) [virtual]

Join a NV_swap_group.

See WGL or GLX implementation and OpenGL extension for details on how to implement this function.

Parameters:
group the swap group name.
barrier the swap barrier name.

Here is the call graph for this function:

bool eq::GLXWindow::configInit (  )  [virtual]

Initialize this window for the GLX window system.

This method first call chooseXVisualInfo(), then createGLXContext() with the chosen visual, and finally creates a drawable using configInitGLXDrawable().

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

Implements eq::OSWindow.

The returned XVisualInfo has to be freed using XFree().

Returns:
a pixel format, or 0 if no pixel format was found.
