- What is a Public Screen?
- ===============================================================================
- Public Screens are new Amiga Screens that can have program windows on them,
- instead of the Workbench Screen, allowing you to avoid shuffling windows around
- the Workbench Screen in order to get to your Icons. A good use of this would be
- for opening a public screen and putting both an Amiga Shell Window and a Clock
- Window, as a CLI work environment, leaving Workbench available for file/icon
- manipulation.
-
-
- ***********************************************
- * WARNING!! WARNING!! DANGER WILL ROBINSON!! *
- ***********************************************
- 1.) Do NOT try to close a PublicScreen Screen any way other than by
- selecting its menu item, or you will crash your Amiga!
- (Other public screen programs are not aware of our menu window.)
-
- 2.) PublicScreen may not find ALL programs that use its screen, and therefore
- not shutdown properly, resulting in an ill/crashed Amiga.
- (OK, I found 1 old program that caused this behavior...)
-
- REQUIREMENTS:
- ===============================================================================
- Amiga OS 2.04 (v37 system libraries) is required to use PublicScreen.
-
- USAGE INSTRUCTIONS:
- ===============================================================================
- CLI Usage: PublicScreen <ScreenName> (defaults to PublicScreen.1 etc.)
- Workbench Usage: Double Click on icon (what else?)
-
- Installation: PublicScreen expects to find the following programs/files
- S:PublicScreen-Startup (a startup script for the shell menu item)
- PublicScreen (in the current dir or C: [I have no paths])
- C:ED (the standard AmigaOS 2.04 Editor)
- SYS:Tools/memacs (the standard AmigaOS 2.04 memacs editor)
- SYS:Utilities/clock (the standard AmigaOS 2.04 clock)
- SYS:Tools/Calculator
- SYS:Tools/Colors (the standard AmigaOS 2.04 Screen colors program)
-
- About the Tools Menu:
- These are currently hardcoded values, through use of some C string
- manipulation, I directly supply ED and SHELL with CON:specs that
- substitute the current screen, for the SCREEN keyword argument.
- CLOCK, CALCULATOR, and MEMACS are SHANGHAI'd by setting that mode
- silently, launching the program and waiting half a second, before
- returning default/shanghai back to their previous off status. The
- Colors program is simply called as it always opens-- front screen.
- In a user configurable version, I will probably have a settable
- DELAY value, for people with slow machines.
-
- In a future release I hope to make this tools menu(s) configurable,
- I just wanted to give something out now that was more usable than
- the previous releases of PublicScreen.
-
- Description: PublicScreen simply opens a Public Screen with the same attributes
- as your workbench screen, (Same Font, Same Screenmode, etc.)
- and stays open until you select the menu item to close the screen.
- (If it finds no other programs using the screen. See Warning above.)
-
- I have included a basic Tools Menu, so you can launch a shell,
- ed-editor, memacs-editor, clock, calculator, and/ Colors windows
- on your newly opened public screens.
-
- PublicScreen has menu items on the public screen for default mode.
- On a 512K CHIP amiga approx 12 non-interlaced public screens can
- be opened, or 6 interlaced ones. These numbers increase with
- 1M CHIP and 2M CHIP machines. Machines with ECS should be able to
- open public screens in Productivity or SuperHires modes, if that is
- how their workbench screen is configured.
-
- If your Workbench Screen is set to a virtual size > actual display
- size, such as going to the Prefs/ScreenMode program and setting
- Width and Height to double their normal value, (1200 Width, 800 Height)
- PublicScreen will open an identical type window. You can thus
- place multiple shell windows in view and out of view.
-
- Requirements: AmigaOS Release 2.04 (v37)
-
- Known BUGS: YES!

- changing CLI template to SCREENAME,FROM/K:
- for SCREENAME=<name_of_screen> and FROM=<startup_file>
- rearranging some code, increasing number and clarity of comments
- since there will be a lot of changes coming.
- REV 2.06: added basic CLI based program launching, and Tools Menu 04/17/92 not released
- fixed bug with CON: opening with wrong font, used wrong screentag, Sorry!!
- replaced some SAS/C specific code with something more portable. 04/19/92 not released
- REV 2.07 Got SCREEN independent program launching working... Yeah! 04/21/92 RELEASED
- REV 2.08 Changed ED commandline to have a proper close gadget, oops!
- Changed CLOCK commandline to be over more to left (fit on no-overscan screens)
- REV 2.09 Added "Colors" to Tools Menu because it was suggested by a user
- REV 2.10 Fixed Bug in Un-default routine, Couldn't shutoff Default mode if was in
- default mode before launching "Shanghai'd" programs, oops! (5/8/92)
- Also program launching with "shanghai" mis-sets the popup and shanghai flags
- when returning (still needs to be fixed).
- FUTURE:
- Rev 3 and Beyond:
- - Add a user configurable menu for launching programs so that once a public
- screen is popped up, it is immediately usable, without switching screens.
- SCREENMODE/Font selection support?
-
- - Add user configurable option to automatically start various programs when
- publicscreen is opened.
-
- - Rewrite program as a Client/Server to allow external controls from Shell
- Scripts, options for starting in default mode, options for non-cloneWB
- Screens (screenmodes/overscan/font/colors)
-
- - Add External (arexx?) Support to 1.)Close Screen
- 2.)Bring Screen to Front
- 3.)Push Screen to Back
- 4.)Open other screens?
-
- - Get closer to the 'ideal application' in Amiga User Interface Style Guide.
-
- Anyone want to create a better Icon?
- Write Some utilities with JUMP gadgets?
-
- NOTICE TO OTHER PROGRAMMERS:
- --------------------------------------------------------
- PLEASE make your programs Public Screen aware, and font sensitive.
