[net.micro.mac] Finder mod to change "Clean Up" grid size

robertm@dartvax.UUCP (Robert P. Munafo) (10/29/85)

I decided one day that I was tired of the simple 64x64 grid spacing that
the Finder was using for the "Clean Up" command, and so I began fooling
around with the debugger to get the Finder to use a 32x32 grid instead.

   After about 5-6 hours of hacking, I found the necessary changes - with
the patches that I list here the Finder can be made to align icons in units
of 32 pixels apart for "Clean Up" and "drag icon into folder" operations.
This allows you to space the icons 1 1/2 spaces apart to fit more icons in
the window without the names overlapping.  It also allows you to put the
icons in a sort of "checkerboard" pattern, an approach that sometimes allows
more icons to be visible at once.

   Here are the patches I used to customize the Finder.  Run MacTools and
edit the May 24th version 4.1 of the Finder, using the "ViewEdit" command:

     Block  Char Change Change          Block  Char Change Change
      num.  num.  from    to             num.  num.  from    to
     -----  ---- ------ ------          -----  ---- ------ ------
     17 a   05c   0020   0010           18 a   004   0040   0020
     17 a   062   0020   0010           18 a   008   0040   0020
     17 a   080   0040   0020           30 a   0ee   0040   0020
     17 a   08c   0040   0020           30 a   0fa   0040   0020
     17 b   124   0040   0020           30 b   104   0040   0020

     17 b   13a   0040   0020           30 b   114   0040   0020
     17 b   1cc   76c0   76e0           59 b   1fc   0020   0010
     17 b   1ce   78c0   78e0           60 a   004   0040   0020
     17 b   1fa   0040   0020           60 a   00c   0020   0010
     17 b   1fe   0040   0020           60 a   014   0040   0020

As you can see, there are 20 patches, most of which change a "64" to a "32"
or a "32" to a "16".  The two exceptions are MOVEQ instructions, but they
also amount to changing a "64" to a "32".  If you don't find the values
indicated in the "change from" column, your copy of the Finder has probably
already been edited (with the Resource Editor, perhaps?)
