This class is available in the Extensions path. It is automaticaly loaded by the TFT_eSPI.h header file. That is, the TFT_eSPI_Button is available by default for your programs.

Public methods

Constructor

TFT_eSPI_Button(void)

Inits

The classic initButton() uses centre & size, whereas the initButtonUL() uses upper-left corner & size:

• void initButton(TFT_eSPI *gfx, int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t outline, uint16_t fill, uint16_t textcolor, char *label, uint8_t textsize)
• void initButtonUL(TFT_eSPI *gfx, int16_t x1, int16_t y1, uint16_t w, uint16_t h, uint16_t outline, uint16_t fill, uint16_t textcolor, char *label, uint8_t textsize)

Adjust label datum

void setLabelDatum(int16_t x_delta, int16_t y_delta, uint8_t datum = MC_DATUM)

Draw

void drawButton(bool inverted = false, String long_name = "")

Tests

If a location is inside the button:

bool contains(int16_t x, int16_t y)

Button status set and check:

• void press(bool p)
• bool isPressed()
• bool justPressed()
• bool justReleased()
