- BAG 1.0 - a Better ActivateGadget Patch Routine
-

- Placed in the Public Domain - Freely Redistributable
-
- Synopsis:
- ---------
- BAG (BetterActivateGadget) is a tiny patch for the Intuition
- ActivateGadget() function. After you install BAG, normal calls
- to the ActivateGadget() function will be redirected through the
- new BAG function. This is similar to the way FastFonts improves
- text output by changing the Graphics library Text() function.
-
- Reasons to use BAG:
- -------------------
- With a fast CPU installed you may find that string gadgets act
- unreliable. This problem is especially noticable with small
- windows containing string gadgets. Many programs do not provide
- sufficient delay after a new Window opens before calling
- ActivateGadget(). This will cause the string gadget to be
- activated in an unpredictable manner.
-
- Theory of Operation:
- --------------------
- BAG modifies the behavior of ActivateGadget() so that up to
- five tries will be made before aborting the activation request.
- Between each unsuccessful attempt, a short time delay (i.e.,
- busy wait) occurs, giving Intuition a chance to finish the
- Window or Requester rendering or refresh and unlock the layers.
- The boolean return from ActivateGadget() is used to determine
- when the activation is successful. The operation of the patch
- function is otherwise identical to the normal ActivateGadget()
- function, and should be transparent in use.
-
- Installation:
- -------------
- BAG should be placed in your C: or other utility directory.
- BAG can be run from the CLI, Workbench, or launched from your
- startup-sequence after SetPatch:
-
- BAG >NIL:
-
- This way you can silently install BAG every time you boot your
- Amiga. Once BAG is installed, it can be removed by simply
- running the program again. BAG only consumes 56 bytes of memory
- when installed and in no way interferes with the normal
- operation of ActivateGadget(), so you should not need to remove
- BAG under normal situations.
-
- Note: BAG only applies to Kickstart V1.2/1.3, since earlier
- versions of Intuition did not have the ActivateGadget()
- function.

- I welcome discussion, comments, criticism, and code
- contributions. Give me a call or drop me a line!
