eventtest(6)
NAME
eventtest - test the waitevent function of svgalib
SYNOPSIS
eventtest
DESCRIPTION
This is a kind of an upgraded keytest(6) and mousetest(6)
demo using the vga_waitevent(3) function.
Use mouse to move cursor. <1>-<9>, <0> to set the cursor
size. <Space> to change the cursor color. Left button to
draw. Right button or <Q> to bailout.
The cursor goes on/off every half second by usage of a
timeout passed to vga_waitevent(3). Every 5 seconds a
string from a child process (the time) arrives asyn
chronously and is displayed by the frontend. This comes in
through a pipe(2) which is monitored by vga_waitevent(2).
You can set a videomode to use by setting the environment
variable 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
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 distri
bution from the net. You even don't need to install it.
Just make in the demos/ subdirecty. As of this writing,
svgalib-1.2.12.tar.gz is the latest version and can be
retrieved by ftp from sunsite.unc.edu at
/pub/Linux/libs/graphics and tsx-11.mit.edu at
/pub/linux/sources/libs which will most probably be mir
rored by a site close to you.
