.TH eventtest 6 "8 April 1998" "Svgalib 1.3.0" "Svgalib User Manual"
.SH NAME
eventtest \- test the waitevent function of svgalib
.SH SYNOPSIS

.B eventtest

.SH DESCRIPTION
This is a kind of an upgraded
.BR keytest "(6) and " mousetest (6)
demo using the
.BR vga_waitevent (3)
function.

Use mouse to move cursor.
.BR <1> - <9> ", " <0>
to set the cursor size.
.B <Space>
to change
the cursor color. Left button to draw. Right button or
.B <Q>
to bailout.

The cursor goes on/off every half second by usage of a
.I timeout
passed to
.BR vga_waitevent (3).
Every 5 seconds a string from a child process (the time)
arrives asynchronously and is displayed by the frontend. This comes
in through a
.BR pipe (2)
which is monitored by
.BR vga_waitevent (2).

You can set a videomode
to use by setting the environment variable
.B SVGALIB_DEFAULT_MODE
to a number (see vgatest
for a list) or a string like G0x1x2 where you replace 0 with desired x
resolution, 1 with the desired y rez, and 2 with the desired number of
colors (2, 16, 256, 32K, 64K, 16M, 16M4). Again, only certain choices are
available, see vgatest for a list.

In case nothing is selected, G320x200x256 is choosen.

This demo is part of svgalib and can be found in the
.I demos/
subdirectory of the original svgalib distribution. However, it is not installed in the system
by default, s.t. it is unclear where you can find it if your svgalib was installed by some
linux distribution. Even then, when you have the demo on your system, you probably won't have
the sources s.t. it is only of limited use for you.

In case of any such problem, simply get an svgalib distribution from the net. You even
don't need to install it. Just
.B make
in the
.I demos/
subdirecty. As of this writing,
.I svgalib-1.2.12.tar.gz
is the latest version and can be retrieved by ftp from
.IR "sunsite.unc.edu" " at " "/pub/Linux/libs/graphics"
and
.IR "tsx-11.mit.edu" " at " "/pub/linux/sources/libs"
which will most probably be mirrored by a site close to you.
