- System 7.0 Notes:
-
- • ProIcon Version 2.0.4 and above are System 7.0 compatible, and will
- operate with virtual memory and 32-bit addressing.
-
- • Apple has changed the pathname used to access files and folders
- on the desktop by inserting the phrase "Desktop Folder" into the
- path. For example, if file "Test Data" on device "HD80" were open
- on the desktop, under System 6.0 it could be referenced from within
- your program as "HD80:Test Data". With System 7.0, you must use
- the string "HD80:Desktop Folder:Test Data". Note that this is
- counter-intuitive Apple's Standard File Dialog, which portrays the
- desktop as being ABOVE any disk devices. For files not on the
- desktop, there is no change from System 6.0 to System 7.0.
-
- • Aliased files can be opened from the Standard File Dialog. At this
- time however, there is no way to open an aliased file using the
- alias name string from within the program. Doing so will open the
- alias itself, not the file to which it ultimately refers. The alias
- file will have an empty data fork.
-
- • To support True-Type, a new function, wfontstyle() has been added that
- allows you to change the type style (bold, italic, etc.) of an entire
- window. See the online help (under "Windows") for information. The
- "Other…" option in the "Font Size" menu allows you to make similar
- changes from the menu bar.
-
- Cautions:
-
- • The launch() function used to sub-launch other applications when
- running under Multi-Finder makes use of a ToolBox trap. Apple
- has stated that this feature may change or disappear in future
- versions of the operating system.
-
- • Icon source files that contain lots of resources will slow down
- compilation and linking, because the resources must be copied to
- the final icode file.
-
- • ProIcon supports large integers; there is no limit to the magnitude
- of numbers produced by integer arithmetic. While calculations with
- large integers are relatively fast, conversion to string form can
- be very time consuming.
-
- • Memory management on the Macintosh is quite complex, and does not
- always detect or recover gracefully from out-of-memory conditions.
- If you experience unexplained errors or program failures and are
- running MultiFinder, try increasing ProIcon's memory allocation by
- using MultiFinder's Get Info menu selection. If you are running
- Finder, try decreasing the size of various execution memory regions.
- This will free up additional space for portions of the ProIcon appli-
- cation.
