General Help...
Welcome to this demonstration of Zinc Interface Library 3.0. The new features and optimizations of Zinc 3.0 allow it to compete directly with Windows-only or DOS-only tools, with the distinct advantage of single source code support for both environments.
This demonstartion program was created with Zinc Interface Library 3.0. Both the Windows and DOS versions were compiled from the same source code (ZINCDEMO.CPP). Both versions also share the same platform-independent resource file (ZINCDEMO.DAT). This file was interactively created with Zinc Designer (included with the product). ZINC3GFX.EXE shows improved performance in DOS Graphics mode using a 3rd party graphics library (GFX from C Source, Inc.)
You may invoke the demo by typing the following:
"WIN ZINCWIN" for Microsoft Windows 3.X
"ZINCDOS" for DOS Graphics Mode,
"ZINCDOS /T" for DOS Text Mode, or
"ZINC3GFX" for DOS Graphics (using GFX)
To evaluate Zinc 3.0 window objects, select the desired object from the menu, tool bar, or list box. Information on the current object will appear in the window in the lower right hand corner of the screen. Press <F1> to see additional information on the object including a sample constructor, if appropriate. (Most Zinc objects have more than one constructor.) You can interact with most the window objects to see how they function (e.g., enter new input information, scroll lists, minimize windows). We encourage you to evaluate this demonstration program in Windows, DOS Graphics and DOS Text modes.

const UI_HELP_Cn event queue and is dispatched to the Window Manager via the application's event loop. The Window Manager forwards event information to the current window object. The window object processes the event or passes it to its parent object (if one exists). This continues until the event is either successfully processed or is discarded.
The sample code below demonstrates how the WINDOW MANAGER is initialized and how window objects (in this case a window with its contents was created in Zinc Designer) are added to the new window:
// Initialize the window manager.
UI_WINDOW_MANAGER *windowManager =
new UI_WINDOW_MANAGER(display, eventManager);
// Read in persistent object resource created in Zinc Designer.

Event Manager Help...
The backbone of Zinc Interface Library 3.0 is its event-driven architecture. This architecture exploits the power of object-orientation to insulate you from the complexities of the operating environment without restricting your access to environment specific features, like the Microsoft Windows messages or the raw scan codes from the keyboard.
Events are received and processed in a Zinc application with Zinc's Event Manager, Window Manager and Event Mapping. The Event Manager maintains a list of run-time devices. Devices included with the library are the keyboard, mouse, and cursor. You can create additional devices, such as pen-based input or serial communications, by deriving a new device from the UI_DEVICE base class.
All events are stored in the event queue in their raw state. Raw event information when running under DOS is the keyboard scan code or mouse state. Under Microsoft Windows, it is the MS Windows message.
Zinc lets you avoid dealing with raw event information (e.g., F1 key, left mouse click, WM_PAINT message), by logically mapping events at the object level (e.g., L_HELP, L_BEGIN_MARK, S_DISPLAY_ACTIVE). Raw input is mapped to the appropriate logical event for the current object. For example, the left mouse click is mapped to L_BEGIN_SELECT if the current object is the window object, and L_BEGIN_MARK if the current object is the text object. This unique feature of Zinc Interface Library permits you to work with event information in a device and object independent fashion and doesn't require you to know specific information about the device that generated the event or the object that receives the event.
Zinc's powerful Event Mapping technology brings you the benefit of adding new devices, such as pen-based input, to existing applications with minimal effort and impact on your code.
The following code demonstrates how the EVENT MANAGER is initialized and how input devices are attached using the overloaded '+' operator:
// Initialize the event manager and attach input devices.
UI_EVENT_MANAGER *eventManager =
new UI_EVENT_MANAGER(display);
*eventManager
+ new UID_KEYBOARD
+ new UID_MOUSE
+ new UID_CURSOR;

Screen Display Help...
Zinc's display classes abstract hardware-specific display standards, including: Monochrome, Hercules, CGA, EGA, VGA, Super VGA and Microsoft Windows 3.X. DOS Graphics display classes support Borland, Microsoft and Zortech graphics libraries.
Display classes for third-party graphics libraries can dramatically improve the performance of the DOS Graphics mode. Sample display classes for Genus and MetaGraphics graphics libraries are available on Zinc's BBS and can be downloaded free of charge.
You can create a display class for your own graphics library by deriving from the UI_DISPLAY base class. You can also create a single executable program that supports both DOS Graphics and DOS Text.
UI_MSWINDOWS_DISPLAY: Microsoft Windows Display
UI_BGI_DISPLAY: Borland Graphics Display
UI_FG_DISPLAY: Zortech Flash Graphics Display
UI_MSC_DISPLAY: Microsoft Graphics Display
UI_TEXT_DISPLAY: DOS Text Mode Display
The following code demonstrates how a Zinc DISPLAY CLASS is initialized:
// Initialize MS Windows 3.X display class
UI_DISPLAY *display =
new UI_MSWINDOWS_DISPLAY(instance, hPrevInstance, nCmdShow);
// Initialize DOS display, trying for graphics first.
UI_DISPLAY *display = new UI_BGI_DISPLAY;

Zinc Designer Help...
Zinc 3.0 offers the tightest integration available between an interactive design tool and the supporting class library. Most Windows developers use a resource tool to help create their program interface. Resource tools are language and library independent by design and therefore cannot access all the features of a given class library. This results in a fragmented approach to application development with isolated user functions and non-specific documentation. You are saddled with the not-so-obvious details of integrating your code with both the class library and the resources you create with the resource tool. The seamless integration of Zinc Designer and Zinc 3.0 contrasts sharply with this a la carte approach.
Zinc Designer lets you interactively create your application screens using Zinc objects. You use a mouse to select windows and window objects from the menu or tool bar and place them on the screen. You can easily customize objects with Zinc Designer's interactive editors. For example, create input fields for formatted information such as a part number or phone number. Just double click on the formatted-string object to open the editor. Now you can enter formatting codes, modify the string identifier, attach context-sensitive help and attach a user function. User functions are attached to input objects, controls and menus via their respective editors. (User procedures can be executed when the field is made current, non-current and/or selected.)
After creating your screens you save them to disk in a platform-independent persistent object file with a .DAT extension. You add these resources to your application with one line of code. You can also load resources you create with the Windows version of Zinc Designer into the DOS version and vice versa.
Zinc Designer's complete access to the Zinc class library, straightforward integration of your code and platform-independent, persistent object storage can dramatically enhance your productivity. With Zinc you can focus your efforts on building great applications instead of wasting time trying to integrate your interface tools.
