Course N1744: Presentation Manager: Windowing & Graphics

Synopsis

This course focuses on advanced windowing topics such as custom dialog controls and Graphical Program Interface (GPI) graphics. You'll examine numerous sample programs and write intensive hands-on lab exercises to reinforce lecture topics. The course is a continuation of Presentation Manager 2.X for Software Developers (N1688). It is intended for OS/2 versions 1.X and 2.X developers.

Who Should Take This Course

OS/2 Presentation Manager programmers who want to raise their skill levels.

How you will benefit

Learn how to:

  • Understand all GPI drawing primitives including lines, arcs, and bitmaps
  • Use GPI programming techniques including transforms, metafiles, and retained graphics
  • Use windowing techniques including subclassing, owner-draw, and user-paint dialog controls and menus
  • Write custom dialog control windows
  • Write programs that use Dynamic Data Exchange (DDE) and the clipboard to communicate with other programs
  • Write programs that perform device-independent output (WYSIWYG: What You See Is What You Get)
