|
|
.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.
