I have 600x800 touchscreen support that is a complete redesign from that used in the "touchpaint" script here:
https://www.mobileread.com/forums/sho...d.php?t=170932
It uses a simple "exit button", which shows a primitive form of what is needed to process onscreen keyboard button presses using the touchscreen.
I have a new unpublished "touchpaint" program that outputs a graphics display list, which can be replayed at a later time. I have used it for signature capture, but it has other uses. I used the redesigned touchscreen code mentioned above (which will also be used in the final onscreen keyboard script when I publish it).
For an onscreen keyboard, you just draw an image of a keyboard, or display a screen capture of one, and define bounding-box coordinates of all the buttons. Then you detect a touch release inside a button and perform its action (usually emitting a character that matches the image on the key). It also helps to have feedback, like inverse display or a larger letter popup (like the apple ipod devices), as you finger moves on and off a defined key region.
I plan to support anything with a 5-way pad too (including the K4). And I will keep the keyboard support used here as well. Instead of touches, you can also select keys by moving through them with 5-way arrow keys, which requires that you define "up/down/left/right" links between them. Obviously, the 5-way "select" would perform the action defined by key (just like a touchscreen release).
Meanwhile, I have released plenty of example code you can use to make your own onscreen keyboard. Things will get easier with time, as I release more stuff.
