Hi,
The main issue with supporting more buttons are that the key codes for them may differ between devices. Also, the GAPI DLL from Microsoft only supports the first three buttons, so the codes for the extra buttons has to be hard coded.
If you (or someone else) have a spare 30 minutes, could I ask you to write a small program that just writes the numeric code for each button on screen? I was actually planning this myself, but my schedule is kind of full...
Using such a program we could start collecting key codes, which later could be integrated into all toolkits (GapiDraw, PocketFrog and EasyCD).
Best regards,
Johan
