NAME

overview − run a program from SunView that takes over the screen

SYNOPSIS

overview [ −w ] [ generic_tool_flags ] program_name [ arguments ] ...

DESCRIPTION

Bitmap graphics based programs that are not SunView based can be run from SunView using overview.  Overview shows an icon in SunView when overview is brought up iconic (−Wi flag) or when the program being run by overview is suspended (for example using ctrl-Z).  Opening the overview icon, or starting overview non-iconic, starts the program named on the command line.  Overview supresses SunView so that SunView window applications won’t interfere with the program’s display output or input devices. 

Overview runs programs that fit the following profile:

own displayThe program needs to own the bits on the screen.  It doesn’t use the sunwindow or suntool libraries to arbitrate the use of the display and input devices between processes. 

keyboard input from stdinThe program takes keyboard input from stdin directly. 

mouse input from /dev/mouse
The program takes locator input from the mouse directly.

OPTIONS

−wThis flag is used to specify that the program being run creates its own SunWindows window in order to receive the serialized input stream from the keyboard and mouse that is provided by the SunWindows kernel driver.  −w tells overview to not convert SunWindows input into ASCII which is then sent to the program being run under overview via a pty.  X and NeWS are programs that fall in this category (as of Dec 86, which is subject to change in the future).

BUGS

Users of overview on a Sun-3/110 frame buffer multiple frames should be aware of the existence of plane groups for pre-3.2 applications.  You can’t successfully run pre-3.2 applications under overview if overview itself is running in the color buffer.  If you start overview so that it is not running in the overlay plane, then the enable plane isn’t be properly set up for viewing the application.  This means that you can’t run overview with the -Wf or -Wb generic tool arguments.  Also, you can’t run overview on a desktop created by suntools using the -8bit_color_only option.
