NAME
tl - install the Turbo Layers Real Time Window Moving System
on the Workbench Screen
DESCRIPTION
Intuition is quite a powerful windowing system. However, if you
try to move a window with the mouse, only an outline box is
is displayed instead of the entire window. TurboLayers tries its
best to cure this problem, making use of the Amiga's Blitter chip.
INSTALLATION
Drag the "tl" icon into the WBStartup drawer of your boot partition
or boot floppy disk, so it will be activated at boot time.
If you don't have a WBStartup drawer, you are probably running
an ancient version of the operating system, and should upgrade as
soon as possible. TurboLayers requires at least Kickstart 2.04.
NOTES
· When you move a window, it blocks for a short time before it
starts moving. This is necessary because the windows which are
located behind this window need the time for refreshing.
This time can be controlled by the DELAY tool type. On the A3000,
a value of 2 is long enough in most cases. However, if you have
a slower machine or a heavily loaded system, some windows may
need more time for refreshing, and you may need to increase this
number.
· While TurboLayers is active, the Workbench screen cannot be closed.
So if you see the requester "To reset the Workbench screen, please
close all windows expect drawers", you must close TurboLayers first
by double-clicking its icon, and then select "Retry" in the
requester.
· Due to implementation details, you should switch off the
"AutoScroll" feature in the ScreenMode Preferences program. If
AutoScroll is switched on, you may encounter a strange effect:
First pull down the Workbench screen to about half the screen
height. Now take a window and move it down as far as possible, and
watch a magic screen appearing behind the "Workbench screen"...
If you move that window fast enough, it is even possible that the
WB screen jumps to an invalid position and stays there, and you
can see some fireworks on the display. Be warned!
· While TurboLayers is active, if you move an icon out of the right
screen border, it magically appears at the left side. This is
normal.
· TurboLayers can also be used from the CLI, try "tl ?"
· For you Assembler freaks out there: TurboLayers is written 100% in
the only language which lets you do this in one afternoon: C!
WARNING
Being a low level hack, TurboLayers plays some nasty tricks with
the Workbench screen. It may break on new versions of the OS...
but will it ever become superfluous? ;-)
