[fpc-pascal] fpGUI - UI Designer - place own components ?

Hi, yesterday I tried fpGUI the first time - I only compiled the examples just to see how it looks. Now I "google and google" for an answer to the question, how to make descendants from the fpGUI visual components and then place my own derived Components into the component palette of

I have 7 RPis and all have been very reliable. One has been up, running a webcam, for over 5 months without pause. Another controls my central heating. Others are file server and garage MP3 player. All have Free Pascal installed. Mark Morgan Lloyd wrote the following on 05/03/15 10:12:44:

If you are interested in bare metal development (without linux as a host OS) then the ST Nucleo boards are a very interesting choice, they come with an integrated ST-Link Debugger interface and have Arduino-compatible headers. Cost is about €12,-- Make sure to get a model with Cortex-M3 or Cor
