- This is "jGNE Helper", formerly a monthly posting to
- the Usenet newsgroup alt.sources.mac.
- It provides an example for INIT programmers
- interested in filtering events before they are handed to
- applications calling GetNextEvent (which is called by
- WaitNextEvent).
-
- The jGNE filter is the Apple-sanctioned method for
- filtering events. It is possible to patch event traps. It
- is sometimes even advisable. But since the jGNE filter is
- the sanctioned method, one ought to attempt to use it
- before patching traps.
-
- This code sample has a specific conflict with older
- versions of PopChar. Newer versions of PopChar have a fix
- which makes them compatible with this code. Users of older
- versions of PopChar should probably upgrade to the current
- version anyway -- this is a very old conflict. The conflict
- manifests itself by rendering a good portion of the screen
- "impervious" to clicks unless the option key is held down.
-
- This version of jGNE Helper was built with both Symantec
- THINK C 7 and Metrowerks CodeWarrior CW7 for 68K machines.
- It's entirely possible to write a native jGNEFilter. I've
- even done it before. However, it hasn't occurred to me how
- to fit a native filter into the context of this sample.
-
- For further info on the jGNE filter, consult your Technotes.
