A-Shell Consolidated Reference

AUI serves as a organizing wrapper for most of the primary classes of functions of the AUI Toolkit.

xcall AUI, CLASS, parameters

We use the object-oriented "class" terminology not to claim that these meet every definition of an object class, but to promote an object orientation to the understanding and use of the functions. Adopting this mind set early on in a text-to-GUI conversion project will reinforce good design and contribute to better results.

CLASS is a string which names the class of interface "object" from the following table.

Class

Description

AUI_CONTROL

Display and input controls. Properties include the control type (button, checkbox, etc.), size and position (using the row/col coordinate system), etc. Methods include create, modify, delete, save, restore, clear, etc. Same as MX_WINCTL.

AUI_EVENTWAIT

Abstract class whose purpose is to provide methods for waiting for an interface event (typically a button to be clicked). Used as an alternative to INFLD or other input routine. Same as MX_EVENTWAIT.

AUI_ENVIRONMENT

Properties related to the interface environment.

AUI_MENU

Menu items. Methods for adding, deleting, and enabling/disabling items. Same as MX_WINMNU.

AUI_IMAGE

Special case of control for images. Same as IMAGE.

AUI_WINDOW

Main display window configuration. Properties include number of rows and columns, status lines, colors. Methods include PRINT and Tab.

AUI_HTMLHELP

Interface with HTML/CHM help files.

other

Other classes can be implemented as SBX modules. xcall APL,CLASS$,... will be treated internally as VXCALL CLASS$,...

 

Note that there are some other class-level objects which could probably be in this table but are not. These controls were either developed before those noted in the table, or were deemed sufficiently important enough to have their own stand-alone function and documentation. Those topics are:

INFLD, the control for handling data input and output.
XTREE, the control for managing trees and listboxes.
XTEXT, the control for managing text functions.
