Hello,
i have much fun developing my own Kindle application, but unfortunately i have a few problems a canīt get to solve. Mainly because i am an electronics engineer and no programmer but i try my best to learn.
I use a Kindle Paperwhite 6. Generation with Firmware 5.12.2.2 and jailbreak (i have also KUAL and USBnet installed).
If i am correct my Kindle only comes with GTK2.0?
I am trying to build my own C Program with GTK2.0.
The Program should make a websocket connection to my websocket server and send json-strings to the websocket server (this part works)
I wand to build a UI for it, like a combination lock, have buttons with the numbers 0 to 9 and one "ok" button. If i have the correct Code the json strings gets send to the websocket server. All of this works, but my problem is the screen: when i press one number and then the next number, the first number button gets black again. i canīt get it to work. I searched this forum, ask ChatGPT and looked at other examples, like gtktetris or kterm but i canīt figure out what my mistake is. Please point me at the right direction
Also how can i get my ui to go fullscreen and not show the "status bar" at the top (with battery and time).
Thank you very much for your help and if i miss something please point it out to me.
