OVERVIEW:
wIconScreen is a program that works with wIconify to create a new screen
just as though you used the wIconify NEW SCREEN menu. The screen will
become the current Workbench screen automatically. wIconScreen is intended
mainly for use in the Startup-Sequence, and in EXECUTE scripts.
USING WICONSCREEN:
To use wIconScreen, wIconify must be runnging. To create a new WB screen,
simply type
1> wIconScreen
and wIconify will open a new screen for you. Any windows that would
normally appear on the Workbench screen will now open on the new screen.
You can change which screen is the current WB screen by using the MAKE WB
menu item of wIconify, or with the wMakeWB command.
To close a screen created with wIconScreen, use the wIconify CLOSE SCREEN
menu item, just as you would for any wIconify screen.
You can specify the depth and resolution flags by including them with the
wIconScreen command. For example,
1> wIconScreen 3 LORES
would open a 3-bitplane low-resolution screen. The depth can be from 1 to 5
(HAM mode will automatically convert to 6 bitplanes), and the possible flags
are:
HIRES for screens 640 pixels wide
LORES for screens 320 pixels wide
INTERLACE for Interlaced screens
HAM for Hold-And-Modify screens
[NO]ACTIVATE to [not] activate the newly created screen
[NO]BEHIND to [not] send the screen to the back once it is openned
These flags may be given in combination, as in the following example,
which opens a high-resolution interlaced screen one bitplane deep,
and activates the wIconify window on that screen:
1> wIconScreen ACTIVATE HIRES INTERLACE 1
The default is to open a HIRES screen of depth 2, not activated, and in
front of all the other screens.
TECHNICAL NOTES:
The actual screen dimensions are calculated from the size of the real
Workbench screen. HIRES screens will open to the smae width as the WB
screen (usually 640), and LORES screens will open to half that size (usually
320). INTERLACE screens will open the the same height as the WB if the WB
is interlaced, and to twice the WB size if the WB is NOT interlace.
Similarly, NON-INTERLACE screens will open to the appropriate mutliple of
the WB screen size.
Screens of depth greater than 2 use the Intuition default color map for
colors of number higher than 3 (the workbench colors are used for the first
four colors, numbered 0 to 3). The color map can be customized using the
custom color map available through the wIconify initialization file.
