- Hi all! (IRC people - I shall return!!!) I have been working on a
- rather large Pascal program which generates a bunch of fractals at once. I
- used to call this multitasking, but I was informed by someone one day that
- using the strict definition of multitasking, it was not. Ok, so whatever
- the hell it is, here are my problems:
-
- 1. The main event loop takes a WHILE, and so if you do an
- operation involving clicking and dragging, there seems
- to be this GS/OS bug that appears. It does the action
- sometimes, but it doesn't show the important part, what
- you are doing. For example, sometimes, when I click on
- a scroll bar, it will drag it in it's mind, and when I
- let go, it will go to the place that I have dragged it
- to, but it won't show me the little box going up and down
- as I pull the mouse up and down. It will only update it
- after I let go! This also happens in another place. Is
- there any way to put events on hold while one is not in
- the 'main' main event loop?
-
- 2. When I make a block of memory with NewHandle, for use as
- a graphport for storing what is in a window, the bottom
- of it will be garbage. For instance, with a 640x400 pixel
- block of memory, anything below line 200 will be junk.
- The boundsrect is ok, and so is the amount of memory. I'm
- stumped.
-
- 3. In order to follow technote #4's directions for changing
- modes, I have to shut down Quickdraw. I used a resource
- to start all of the tools, so I don't know Quickdraw's
- direct page to restart it! What should I do?!?!?
-
- Well there they are! Any and all help would be imensely appreciated, but
- due to the sheer volume of all the messages here, I would really appreciate
- it if any answers were sent by e-mail. Also, anyone have a copy of
- Complete Pascal that they would be willing to part with? I'm not gonna
- risk sending $$$ to that guy, I have heard that he sometimes doesn't send
- the products out, but keeps the $$$! Anyway, in regards to these
- programming problems, any help would be greatly appreciated and would
- certainly earn you a place in the credits. The final program will be
- public domain. All of the fractal fans out there can look for a beta
- version to be out in just a few months.
