Chapter 3 - Using MonitorMouse for OS/2
Click Sound on Touches
A check box is available in the Touchscreen Control Panel for enabling/disabling
the "click" sound from the PC’s internal speaker for each touch. Audible feedback
is important because the touchscreen does not have any tactile feedback
mechanism. CONFIG.SYS is updated with the new setting (-b flag). Beeps are
enabled by default.
Double-Click Area
The double-click area may be specified in the Touchscreen Control Panel. This
area is used for detecting double-clicks in mouse button emulation mode 6.
Normally, OS/2 expects a double-click to be on the same pixel
−
easy to do with a
mouse, but almost impossible with a touchscreen. By expanding this area, it
becomes easier to double-click by double-tapping anywhere within this area. The
default number of pixels for X and Y are calculated after you calibrate the
touchscreen. CONFIG.SYS is updated with the new values (-a flag).
Border Width
To make resizing windows easier with the touchscreen, increase the Border Width
for the desktop. A value of 17 is recommended for 640x480 video resolution, 26
for 1024x768. For other resolutions, pick a border width that visually matches the
title bar width. Wide borders may look strange at first, but after awhile they will
seem normal. The new border width will not be reflected until the system is
rebooted.

The following are suggestions for using the touchscreen with Presentation
Manager. Mouse button emulation mode 6 is assumed.
Removing the Mouse Pointer
A mouse pointer is not required in most touchscreen applications and may actually
be a distraction. The user's eyes will follow the pointer's movement instead of
focusing on the application. With a pointer present, the user performs the indirect
act of moving the arrow to an object instead of the direct, natural act of touching
the object.
With OS/2 3.0 (Warp), it is possible to disable the mouse pointer as follows:
1.
Open the OS/2 System folder, then System Setup.
