Detailed Description

framebuffer generic core window interface.

Provides interface for core renderers to the framebufefr toolkit drawable area.

This module is an object that must be encapsulated. Client users should embed a struct fb_corewindow at the beginning of their context for this display surface, fill in relevant data and then call fb_corewindow_init()

The fb core window structure requires the callback for draw, key and mouse operations.

Definition in file corewindow.c.

Function Documentation

fb_corewindow_fini()

nserror fb_corewindow_fini

(

struct fb_corewindow *

fb_cw

)

finalise elements of fb core window.

Parameters

fb_cw

A fb core window structure to initialise

Returns

NSERROR_OK on successful finalisation otherwise error code.

Definition at line 277 of file corewindow.c.

References NSERROR_OK.

Here is the caller graph for this function:

fb_corewindow_init()

nserror fb_corewindow_init	(	fbtk_widget_t *	parent,
		struct fb_corewindow *	fb_cw
	)

initialise elements of fb core window.

As a pre-requisite the draw, key and mouse callbacks must be defined

Parameters

fb_cw

A fb core window structure to initialise

Returns

NSERROR_OK on successful initialisation otherwise error code.
