Member Function Documentation

◆ begin_flip()

virtual void IPhoneGraphicsWindow::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 GraphicsOutput.

◆ begin_frame()

virtual bool IPhoneGraphicsWindow::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.

◆ clear_pipe()

virtual void IPhoneGraphicsWindow::clear_pipe ( )
virtual

Sets the window's _pipe pointer to NULL; this is generally called only as a precursor to deleting the window.

Reimplemented from GraphicsOutput.

◆ end_flip()

virtual void IPhoneGraphicsWindow::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.

◆ end_frame()

virtual void IPhoneGraphicsWindow::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.

◆ process_events()

virtual void IPhoneGraphicsWindow::process_events ( )
virtual

Do whatever processing is necessary to ensure that the window responds to user events.

Also, honor any requests recently made via request_properties().

This function is called only within the window thread.

Reimplemented from GraphicsWindow.

◆ set_properties_now()

virtual void IPhoneGraphicsWindow::set_properties_now ( WindowProperties properties)
virtual

Applies the requested set of properties to the window, if possible, for instance to request a change in size or minimization status.

The window properties are applied immediately, rather than waiting until the next frame. This implies that this method may *only* be called from within the window thread.

The properties that have been applied are cleared from the structure by this function; so on return, whatever remains in the properties structure are those that were unchanged for some reason (probably because the underlying interface does not support changing that property on an open window).

Reimplemented from GraphicsWindow.
