void wglGraphicsWindow::begin_flip ( ) [virtual]

This function will be called within the draw thread after end_frame() has been called on all windows, to initiate the exchange of the front and back buffers.

This should instruct the window to prepare for the flip at the next video sync, but it should not wait.

We have the two separate functions, begin_flip() and end_flip(), to make it easier to flip all of the windows at the same time.

Reimplemented from WinGraphicsWindow.

Definition at line 140 of file wglGraphicsWindow.cxx.

bool wglGraphicsWindow::begin_frame ( FrameMode  mode,
Thread current_thread 
) [virtual]

This function will be called within the draw thread before beginning rendering for a given frame.

It should do whatever setup is required, and return true if the frame should be rendered, or false if it should be skipped.

Reimplemented from GraphicsOutput.

Definition at line 63 of file wglGraphicsWindow.cxx.

References GraphicsOutput::begin_frame_spam(), GraphicsOutput::clear_cube_map_selection(), wglGraphicsStateGuardian::get_context(), GraphicsOutput::get_fb_properties(), and GraphicsWindow::get_unexposed_draw().

void wglGraphicsWindow::close_window ( ) [protected, virtual]

Closes the window right now.

Called from the window thread.

Reimplemented from WinGraphicsWindow.

Definition at line 209 of file wglGraphicsWindow.cxx.

void wglGraphicsWindow::end_flip ( ) [virtual]

This function will be called within the draw thread after begin_flip() has been called on all windows, to finish the exchange of the front and back buffers.

This should cause the window to wait for the flip, if necessary.

Reimplemented from GraphicsOutput.

Definition at line 185 of file wglGraphicsWindow.cxx.

References wglGraphicsStateGuardian::get_context().

void wglGraphicsWindow::end_frame ( FrameMode  mode,
Thread current_thread 
) [virtual]

This function will be called within the draw thread after rendering is completed for a given frame.

It should do whatever finalization is required.

Reimplemented from GraphicsOutput.

Definition at line 108 of file wglGraphicsWindow.cxx.

bool wglGraphicsWindow::open_window ( ) [protected, virtual]
void wglGraphicsWindow::ready_flip ( ) [virtual]

This function will be called within the draw thread after end_frame() has been called on all windows, to initiate the exchange of the front and back buffers.

This should instruct the window to prepare for the flip when command, but will not actually flip

We have the two separate functions, begin_flip() and end_flip(), to make it easier to flip all of the windows at the same time.
