7" screen_RA8875_ STMPE610 coding help

[ribbonman]

I was able to get the GFX buttons to display with the text on them by commenting out some code in the AdafruitRA8875.h library and things seem to be working OK, it also worked with the earlier code on post #13 and doesn't seem to bother the tft.textWrite() portion of the code I used.
I have to figure out the switch case functions for the button grid on post #13 as there seems to be a problem with the rotation function giving me an error on compile.

Code commented out in Library follows.

virtual size_t write(uint8_t b) {
    textWrite((const char *)&b, 1);
    return 1;
  }

 virtual size_t write(const uint8_t *buffer, size_t size) {
    textWrite((const char *)buffer, size);
    return size;
  }

I haven't had any luck getting my grid of buttons to act the way I want and I'm not sure what to change.
My code is using a switch statement to change the color of the button when touched but I get a compile error (not declared in this scope) when I try to convert it to work with the RA8875 driver. I'm not sure what the terminology of the RA8875.h file is meaning and any help in direction to go is appreciated.
old code

TS_Point p;
int x, y;
const byte row = 4;
const byte col = 2;
byte lastHit = 0;
byte currentHit = 0;
Adafruit_GFX_Button btn[row*col];

void loop() {
  if (!ts.bufferEmpty()) {
    p = ts.getPoint();
    switch (rotation) {
      case 0:
        x = map(p.x, TS_MINX, TS_MAXX, 0, tft.width());
        y = map(p.y, TS_MINY, TS_MAXY, 0, tft.height());
        break;
      case 1:
        // p.x, p.y reversed //
        x = map(p.y, TS_MINY, TS_MAXY, 0, tft.width());
        y = map(p.x, TS_MAXX, TS_MINX, 0, tft.height());
        break;
      case 2:
        x = map(p.x, TS_MAXX, TS_MINX, 0, tft.width());
        y = map(p.y, TS_MAXY, TS_MINY, 0, tft.height());
        break;
      case 3:

        y = map(p.x, TS_MINX, TS_MAXX, 0, tft.height());
        break;

    }

    while (ts.touched()) {
      for (uint8_t b = 0; b < row * col; b++) {
        if (btn[b].contains(x, y)) {
          btn[b].press(true);
