Customizing the touch response mode
The touch response mode defines how your touch emulates the functions of a mouse.
For example, you can define a touch to produce a button down (pressing a mouse
button) or button up (releasing the mouse button). Touch modes also define how your
touch produces a mouse click and double click. TouchWare allows the following touch
modes:
Desktop (default)
The system moves the cursor to the touch point, but does not generate a
button down as long as you continue to slide your finger around the screen.
When you pause and hold your finger steady, the system generates a mouse
button down. You can now slide your finger around the screen with this
position. When you lift your finger, the system generates a button up.
Drawing
The system moves the cursor to the touch point and immediately generates a
button down. You can slide your finger around the screen with the button held
down. When you lift your finger, the system generates a button up.
Button The system moves the cursor to the touch point and immediately generates a
button down and up (a click). To drag, slide your finger around the screen
(button down). When your lift your finger, the system generates a button up.
Click The system moves the cursor to the touch point and then immediately
generates a button down and up (a click). Click mode does not generate a
second button down, does not support drag and does not generate a mouse
event on finger lift-off.
