Icons Interactive Help System

Step 8: Interface Editing:

1) Just like most Graphical User Interfaces, Icons can have Screensavers and Background Images. to edit these settings, Press Apps and Select "Edit Interface"
2) Icons has a built in Screensaver called lines. It should be already defined for you. Any program that can exit by pressing any key will do. clearing the "program name" box will tell icons to use the Power Saver feature of Icons
3) The time is a generic number used for telling Icons when to run the screensaver based on how many times it loops through the getkey routines. the bigger the value, the longer it takes. selecting none shuts the Screensaver Function off.
   4) Put the name of the picture you want as a background in the Interface Picture Box. You can also use the <foldername>\<picname> logic here as well. after you finish your changes, press enter to save your changes or Esc to cancel
5) as you can see, the Background image is there now. if you're wondering where the picture comes from, it comes from FF7. Basically, any full screen picture will do.
6) after a couple of seconds, the screen saver automatically comes up as well.
7) if the program name is removed from the program name box, but the timer is not set to none, this box appears. it makes the processor go from full load to partial load, which saves battery life.
8) this appears if the Screen Saver crashes or was typed incorrectly in the "Program name" box. Icons sets the screen saver time to NONE, disabling the screen saver.
After you do the above, go to Step 9: Other Options

Q: Why not have a Tile function for background pictures?
A: It cannot be done correctly on a Ti-89/92, as well as taking too much time.
The only way it can be done is if the user tells icons the height and width of the picture, as well as taking forever to draw the picture 20 or so times. It would save memory, but it would also slow down icons and make it less stable.
