# gui\_shadow\_box\_proc(3alleg4)

Hooks to customise the look and feel of Allegro dialogs.

## NAME

gui\_shadow\_box\_proc, gui\_ctext\_proc, gui\_button\_proc, gui\_edit\_proc, gui\_list\_proc, gui\_text\_list\_proc - Hooks to customise the look and feel of Allegro dialogs.

## SYNOPSIS

**#include \<allegro.h\>**

**extern int (\*gui\_shadow\_box\_proc)(int msg, struct DIALOG \*d, int c);**

**extern int (\*gui\_ctext\_proc)(int msg, struct DIALOG \*d, int c);**

**extern int (\*gui\_button\_proc)(int msg, struct DIALOG \*d, int c);**

**extern int (\*gui\_edit\_proc)(int msg, struct DIALOG \*d, int c);**

**extern int (\*gui\_list\_proc)(int msg, struct DIALOG \*d, int c);**

**extern int (\*gui\_text\_list\_proc)(int msg, struct DIALOG \*d, int c);**

## DESCRIPTION

If set, these functions will be used by the standard Allegro dialogs. This allows you to customise the look and feel, much like gui\_fg\_color and gui\_bg\_color, but much more flexibly.
