[Question] About keybord and touchpad interaction within X

[JJ Ding]

Hi everyone,

Notebooks usually have a touchpad as the default pointing device, and it
is most often placed just below the keyboard. This makes typing
sometimes annoying because users might touch the touchpad
unintentionally and cause the cursor to move away from your current
window or accidentally make the desktop or other windows active.

Although some touchpads have the capability to sense palm actions, I
think palm detectoion is often not enabled by default, or just
unavailable. So is there any method to make X disable touchpad when
typing, or any API so I can write a program for this functionality?

Any help would be appreciated, thank you very much.

Best regards,
JJ
