Description

Draw string right justified do dX.

Signature

• int16_t TFT_eSPI::drawRightString(const String& string, int32_t dX, int32_t poY, uint8_t font)
• int16_t TFT_eSPI::drawRightString(const char *string, int32_t dX, int32_t poY, uint8_t font)

Parameters

• const String& string: String to be displayed (reference to String instance).
• const char* string: String to be displayed as array of char, null terminated.
• ìnt32_t dX: end x coord.
• ìnt32_t poY: y coord.
• uìnt32_t font: Font to be used.

Result

int16_t: displayed string x size.

Example

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_BLACK);
  tft.setTextColor(TFT_WHITE);
}

void loop() {
  tft.drawRightString("Hello, World!", 240, 20, 2); // Draw string aligned to the right at x=240, y=20 with font type 2
  delay(1000);
}

This example initializes the TFT_eSPI library, sets the screen rotation, fills the screen with black, sets the text color to white. Then, in the loop function, it uses the drawRightString method to draw the string "Hello, World!" aligned to the right at the specified coordinates with a font type of 2.
