Help needed: How to make a library from a .ino-file?

Great, thanks!

Question:
How do I call a library function from inside the library? With the CLASSNAME:: in front or without?

Like this?

void EDIPTFT::sendData(char* data, byte len) {
  if (_smallprotocol) {
  }
  else {
    unsigned char i;
    for(i=0; i < len; i++) {
      Serial3.write(data[i]);
    }
  }
}

void EDIPTFT::Clear() {
  char command [] = {12};
  EDIPTFT::sendData(command,1);
}
