About

If you have seen the Speech Manager, then you know that a background only application can put a window onto the screen (contrary to popular belief). The new Text Services Manager in System 7.1 offers documented hooks for creating, disposing, and handling floating windows. These windows are layer independent (they are floating above all programs and windows), and can work without patching traps (well, a quick jGNEFilter, but no traps). This program demonstrates a shell application that puts a TSM window onto the screen, and intercepts update, click, and key events. If you don't care to look behind the scenes, you simply write the handlers from the templates. If you want to see how it really works, you can lift the curtains and look in the other functions for yourself. Other programs that use this shell include: ObiWan, Extensions Strip, HoverBar, Virtual, and NotifyMail. Note: that Apple software uses the layer manager in undocumented ways to get the same effect for software such as AppleGuide, Control Strip, and the Speech Manager. Bug Fixes/Changes 2.01 -> 2.03 (2.02 was not released to the public) * Updated the TestScreenSaver() function to count to 3 before hiding/showing the window, which reduces flicker and stops the window from acting strangely during PopupMenuSelect(). * The jGNEFilter helper sets the current app's A5-world (not ours) so that it can call FindServiceWindow(), and we don't need to repeatedly test PtInRgn(). * Replaced the Fat WDEF with 68K and PPC parts to reduce footprint. * Fixed a memory leak with RmveResource() in Prefs code. * The sample drag handlers now setup and restore our A5-world. * Updated the process description for creating a Fat Binary. * Dropped the Symantec C code duplication for archive size. If you need help porting AppeWin, drop me a line. * Updated the bundled TSM Fix from 1.02 to 1.03. See the associated ReadMe file for relevant changes. * Updated documentation and comments. Its yours if you like it. This shell is free for you to modify and expand upon.
