/* guivio.h */
* Interface for VIO (console) user interface for OS/2. Work by Lee Johnson
* except a few fixes by herbert.
* herbert:
* - added macro stuff to avoid trouble when compiling with emx/gcc.
* - addes "static" qualifiers for function prototypes where necessary.
#if !defined(_GUIVIO_H)
#define _GUIVIO_H
* A VIO color index. The four high-order bits contain the background
* color, while the four low-order bits contain the foreground colour.
* Unlike the ANSI console, 'bright' colours may be used for the
* background, and all 256 combinations are valid (though 16 of them
* lead to invisible text. :-)
typedef unsigned char VCOLOR;
/* Structs of this type are used to remember the location and size of each
* window. In the VIO interface, all windows must be as wide as the
* screen, and the sum of all windows' heights must equal the screen size.
typedef struct vwin_s
struct vwin_s *next; /* some other window on this screen */
int height; /* size of the window */
int pos; /* position of the window */
int newheight; /* height after screen is rearranged */
int newpos; /* position after screen is rearranged */
int cursx, cursy; /* logical cursor position */
ELVCURSOR shape; /* logical cursor shape */
* The following buffers hold the colour indices for the various
* fonts.
VCOLOR vc_normal;
VCOLOR vc_fixed;
VCOLOR vc_bold;
VCOLOR vc_emph;
VCOLOR vc_italic;
VCOLOR vc_underline;
VCOLOR vc_hilite;
* Macro definitions:
#define PM_RequestUpdate(pw) \
{ if (!(pw)->destroyed) (pw)->update_me = ElvTrue; }
* GUI function declarations. (Not all of these are actually defined.)
