Windows Pen Driver: UCLKPEN.DRV
The Windows pen driver (UCLKPEN.DRV) interfaces the pen digitizer to WinĆ
dows 3.1. The digitizer may be based on resistive touchĆpanel technology; or it
may use active electronics.
Pen Applications
When Microsoft Windows for Pen Computing is executing, the driver acts as a
pen device. At other times, the driver acts as a mouse device. Usually, the pen
simply appears as a mouse device
.
Any Windows application that can use a
mouse can use the pen
.
Note that penĆdown" is equivalent to pressing the left,
or inner," button on a desktop mouse.
If
Microsoft Windows for Pen Computing is loaded, the pen can appear to be both
a mouse and an ink device
.
The Microsoft Windows for Pen Computing developĆ
er's kit documents the inking API that captures and manipulates ink input.
Now, which mode should your application use: mouse or inking device? In generĆ
al, applications that do not require handwriting recognition should simply treat
the pen as a mouse
.
Mouse input is quite adequate for pointing and drawing
tasks such as signature capture
.
Microsoft Windows for Pen Computing requires
additional storage and processing resources; therefore, it should be used when
handwriting recognition is a requirement.
Installation
Place the files in the following directories:
File Directory
PENALIGN.EXE WINDOWS\
NORWINPM.DRV WINDOWS\SYSTEM
UCLKPEN.DRV
WINDOWS\SYSTEM
PENWIN.DLL WINDOWS\SYSTEM
Configuration
You can configure the Windows pen driver by editing the appropriate entries in
SYSTEM.INI. Unless otherwise noted, all entries are placed in the 
[Pen
Driver]
" section of SYSTEM.INI.
To install UCLKPEN.DRV, place a keyword on the 
drivers=
" line, in the
[
boot
] section of SYSTEM.INI, and add a line to the 
[
drivers
]
" section of
SYSTEM.INI equating the keyword with the actual path to UCLKPEN.DRV. If
you are using Microsoft Windows for Pen Computing , place the pen driver entry
in the [boot] section of SYSTEM.INI (drivers=...) before the (penwindows) entry,
in the [drivers] section of the SYSTEM.INI. Although the following example
shows Microsoft Windows for Pen Computing being installed, it is not required
for digitizer use.
