/************************************************************************************
|
|
* Patch to SFGetFile/SFPGetFile (PACK3 selectors) for puppet string Open. This patch
|
|
* is reached after we have told the application that there was a mousedown in the menu
|
|
* bar, and then that the user selected the "OpenÉ" item from the menu. The application
|
|
* calls PACK3, which we patch to come here. Instead of the usual modal dialog, we
|
|
* just return a specification for the file being puppet Open'd. Of course, we have to
|
|
* go through the normal hoops, like checking the type list and calling the file filter.
|
|
* NOTE: This only works with the older-style SFGetFiles that employ a Working Directory.
|
|
* The newer FSSpec-based ones are not supported, since callers using them should also
|
|
* be AppleEvent-aware, and therefore never require puppet-stringing.
