HI Albert I am not sure if I have the skills to help here or not but I am facing the same sort of situation.
I made my own keyboard in Linux by altering configuration files. keys like QWERTY map to underlying identifications that can be assigned to a different map. Did you want the keys to type a different character only while in a FLTK app ? This is my case and I have to work through it. I work with scientific instruments. I have been teaching myself to program for 8 years to move the business towards selling software to control scientific instruments. Your project sounds interesting. Are you colony counting? I looked into a keyboard with LCD keys but it was >$1K. What about creating an application that uses a touchpad. My main concern with this, would be the difficulty in locating the parts of the screen to push. Perhaps a plastic mask could be applied over the touchscreen that might even have braille like protrusions. My interest in this is for my son who was autism and a severe speech delay. I believe that the English language's defective spelling system is complicating the recovery of people suffering from autism. Many can read quite well but struggle with speech. I am hoping to make a program for him that will show pictures, how they are spelled and then will prompt him to type a phonetic representation so he can practice organizing the sounds in a visual way I move very slowly but I can offer 40-100 hours of work over the next 3 months if there is something that will lead us both to a solution. -Patrick On 12/06/2012 11:23 AM, Albrecht Schlosser wrote: > Hi, FLTK users, > > I'm looking for a keyboard extension or a special function keyboard > that can be used to type special keys normally not found on a standard > computer keyboard, or maybe a keyboard extension that can be used > with FLTK.
