Black buttons?

[vkichline]

I can create, add and render ezLabels with no trouble, but not ezButtons:

  ezWindow test(50, 50, 220, 80);
  ezButton ok(110, 200, 100, 32, "OK");
  ...
  test.setTextColor(TFT_BLACK);
  test.drawString(testString, 0 , 20);
  test.push();

  ok.colors.text = WHITE;
  ok.push();

(This is your scroll demo, with a button added)
The button renders solid black, until I touch it, then it renders OK in white.
If I omit ok.colors.text = WHITE;, it always remains black, even when touched.
What am I leaving out? I expect the default behavior that renders something readable, as ezLabel does.
The code looks like the default should be black text on white background, with no change when pressed.

This, which I think is what you mean, which renders a default style button for me:

#include <M5Core2.h>
#include <Core2ez.h>

ezWindow test(50, 50, 220, 80);
ezButton ok(110, 200, 100, 32, "OK");

String testString = "This is a really freaking long sentence that is not supposed to fit in the window so we can see it scrolls...";

void setup() {
  ez.begin();

  test.spriteBuffer();
  ez.Screen.add(test);
  ez.Screen.focus();
  test.colors.outline = TFT_BLACK;

  test.setTextDatum(TL_DATUM);  
  test.setTextPadding(0);
  test.ezFont(FSSB18);
  test.spriteBuffer(test.textWidth(testString), 80);
  test.setTextColor(TFT_BLACK);
  test.drawString(testString, 0 , 20);
  test.push();

  ok.colors.text = WHITE;
  ok.push();
  
}

void loop() {
  ez.update();
}

(Note that buttons (and all widgets) add the default screen. if you do someOtherWindowOrAnyOtherWidget.add(widget) it will be taken from there and added to the new window/widget) Still need to change some examples to this: they explicitly add where that's not necessary anymore.)

That renders no button at all for me. What does work is:

void setup() {
  ez.begin();

  test.spriteBuffer();
  ez.Screen.add(test);
  ok.colors = { RED, BLACK, RED };
  ez.Screen.add(ok);
  ez.Screen.focus();
  test.colors.outline = TFT_BLACK;

  test.setTextDatum(TL_DATUM);
  test.setTextPadding(0);
  test.ezFont(FSSB18);
  test.spriteBuffer(test.textWidth(testString), 80);
  test.setTextColor(TFT_BLACK);
  test.drawString(testString, 0 , 20);
  test.push();
}

I don't understand when to push, and the required order of operation isn't clear. But I think all of that will go away with (excellent) docs. In leu of docs, one can see if the nomenclature is intuitive. Perhaps this is based on a framework I'm not familiar with; I'm having some difficulty.
