RTPEG-32 (Real-Time Portable Embedded Graphics) provides the
building blocks for a powerful and extensible graphical user
interface. Advanced clipping techniques, font support, graphic image
support, and an object oriented methodologies are incorporated in
RTPEG-32.
RTPEG-32 is Swell Software Inc.'s product PEG ported to On Time
RTOS-32 by On Time.
This programming manual contains a general introduction and
programming tips for using RTPEG-32. The RTPEG-32 API class reference
is supplied in the RTPEG-32 Reference Manual.
The main features of RTPEG-32 are:
- True Windows 95 Look-and-Feel
RTPEG-32 includes a full set of controls which look and behave the
way users expect. Predefined classes include buttons, bitmaps, check
boxes, scroll bars, menus, progress bars, radio buttons, prompts,
combo boxes, dialog boxes, lists, tree views, etc.
- Event Driven Programming Model
User interface objects of an application are typically C++ classes
derived from a predefined RTPEG-32 class. Such a derived classes can
override methods such as Draw to implement a custom appearance, or
they can override Message to catch messages sent by a user input
device, separate threads, or other GUI controls.
- Rich Set of Drivers
A driver for VGA, 16 color mode, is included, as well as high
performance drivers for 8-bit, 16-bit, 24-bit, and 32-bit color
depth with arbitrary resolution. These drivers require VGA
compatible hardware or VESA BIOS support. The source code of these
drivers is included, allowing easy adaptation for custom video
hardware.
- Keyboard Support
RTPEG-32 applications can be navigated using only the keyboard, if
no mouse or other pointing device is available.
- Mouse (MS Serial and PS/2) an Touch Screen Support
Standard Microsoft compatible mice are and PS/2 touch screens
supported.
- Never Disables Interrupts
All RTPEG-32 operations are fully interruptable. Real-time
performance is never affected.
- Supports (But Does Not Require) RTKernel-32
Several threads can perform screen output simultaneously. RTPEG-32
performs all required locking. Even the simultaneous execution of
several modal windows is supported (e.g., to signal error conditions
while other threads continue to run).
- GUI Design Tools
Program WindowBuilder is a rapid prototyping and design tool used to
quickly create RTPEG-32 graphical objects such as bitmaps, fonts,
windows, etc.
- Win32 Emulation Library
The RTPEG-32 Win32 Emulation Library allows executing RTPEG-32 GUI
programs under Microsoft Windows.
- Unicode Support
The Unicode version of RTPEG-32 allows using fonts with up to 65535
characters, for example, to support Far East languages and
multi-language programs.
