 This article last reviewed: 05 May 1989

 This article summarizes changes and additions to the Apple IIGS ToolBox
 that result from Apple IIGS System Disk 5.0.

 The Toolbox on the Apple IIGS has been modified to support a number of new
 features that are available to developers.  (If these new features are used
 in a program, the user must have Apple IIGS System Software 5.0 for the
 software to function correctly.)

 The Resource Manager and Text Edit are new for System Disk 5.0.

 Additional documentation is available from APDA.


 Control Manager
 ---------------
 The Control Manager has been modified to provide support for more standard
 control types, including:
 - StatText Control -- Display text messages in a rectangle.
 - PictureControl -- Display a picture in a rectangle.
 - IconButtonControl -- Icon drawn in a rectangle.
 - LineEditControl -- Line Edit item used in List Manager.
 - TextEditControl -- Works with new TextEdit Tool.
 - PopUpControl -- Provide multiple selection buttons within scrolling lists.
 - ListControl -- You can now use the control manager to manipulate items in
  the List Manager.


 Desk Manager
 ------------
 The classic desk accessory (CDA) menu now supports scrolling when more than
 thirteen CDAs are installed. CDAs are accessed by pressing COMMAND-CONTROL-ESC
 on the keyboard.  Because of this change, selections no longer wrap around the
 screen.  The number of CDAs is limited by disk space and boot time to install
 the files. You may have problems if you install more than 128 CDAs.


 Event Manager
 -------------
 The Journaling feature is changed, to better support the ReadMouse function.

 Font Manager
 ------------
 A problem was fixed in ChooseFont, which caused the system to hang if any
 update events were pending when the call was made.


 Line Edit
 ---------
 Line Edit now supports a password field, in which the characters typed by
 the user appear on the screen as asterisks (*).


 List Manager
 ------------
 The List Manager has been changed to make it easier for programmers to use,
 and to support new controls in the Control Manager.


 Memory Manager
 --------------
 The Memory Manager has been modified to improve system performance.


 Menu Manager
 ------------
 The Menu Manager now supports a number of new features, including:
 - Outline and Shadow text styles in a menu
 - scrolling menus
 - pop-up menus


 Note Sequencer
 --------------
 The Note Sequencer has been modified to make it easier for developers to
 create and use sequences in programs.


 Print Manager
 -------------
 The PrChoosePrinter call has been removed.  Users should use the Control
 Panel to select printers. If an application makes this call, a dialog appears
 on the screen telling the user to use the Control Panel to select a printer.
 When printing in draft mode to a text printer, the driver translates
 QuickDraw II commands into command sequences for the printer.


 QuickDraw II
 ------------
 QuickDraw II has been modified to function faster.


 Resource Manager
 ----------------
 The Resource Manager is an INIT file that is loaded when the Apple IIGS is
 started, and stays loaded when the system is running. The Resource Manager
 maintains the resource fork of a file.  This is similar to the resource fork
 in the Macintosh. This is the first time the a resource fork has existed in
 the Apple II world.  The format of the data is defined by the application.
 Resources are referred to by a resource type and resource ID number.


 Sound Tools
 -----------
 Four new calls have been added to the sound tools, allowing greater
 flexibility when playing sounds.


 Standard File
 -------------
 Standard File has been modified to fully support GS/OS path names.  The
 following are GS/OS values, not the ProDOS FST values. These include:
 - 13,107 files in a folder
 - 254 characters in a file name (using new calls)
 - 508 characters in a path name
 - The List Manager is being used
 - Scan of AppleShare File Server volume every 8 seconds
 - Checks for write-protected volumes and folders
 - Displays the lock icon next to current path name
 - Calls to support multi-selection calls
 - Hook so applications can draw custom list items


 Text Edit
 ---------
 This is a new feature of Apple IIGS System Software 5.0.  It provides standard
 text editing for any application. It can be used as a complete text editor or
 as the core of a simple word processor.  It is similar to Text Edit calls on
 the Macintosh. The following features are included in GS TextEdit:
 - Edit any amount of text that fits in memory (not 32K as in the Macintosh)
 - Mouse activity for text selection (single, double, triple clicking for text,
  words, lines)
 - Auto word wrap
 - Cut, Copy, and Paste
 - Some support of control keys for text manipulation
 - Stylistic variations in the text (fonts, sizes, style, color).
 - Text can contain a "ruler" to format the text
 - Four types of justification
 - Three kinds of Tab support
 - Programmer can limit the amount of information that can be entered
 - Vertical scrolling in a window
 - Automatic drag selection
 - It is FAST


 Window Manager
 --------------
 Numerous changes speed things up and support the Resource Manager.
