- Okay. I want to write some sort of accessory (either an Init or an NDA) so
- menus can be accessed without using the mouse, in a manner similar to
- MicroSoft's (on the IBM) or ProTerm (but on the desktop).
-
- The options I considered are:
-
- 1. Completely fake mouse movements so that the entire system thinks the user
- is actually using the mouse.
-
- Drawbacks: The mouse pointer would jump around as the user presses keys.
- It's hard and long.
-
- 2. Patch GetNextEvent to eat mouse events and generate mouse events based on
- keypresses (would use a flag for Normal mode//Menu mode)
-
- Drawbacks: It's awfully hard to patch GetNextEvent when GSBug uses
- GetNextEvent to get its keyboard input.
- The code would probably be pretty large and incompatibilities
- might be a big problem.
-
- 3. Patch MenuKey to get keypresses and call the apropriate routines in the
- Menu DefProc to do all the "dirty work"
- This is probably the "cleanest" approach.
-
- Drawbacks: There is no way of knowing where the standard DefProcs are
- loacted. This would only work for custom menus.
-
- Suggestions?
