How to center a text?

[PépéMax]

Hello everyone,
Quiz, I have a question, how can I do to center my text on the screen.

My code:void Display_WiFi_Connected() {
M5.Lcd.clear(BLACK);
M5.Lcd.setTextSize(2);
M5.Lcd.print("M5Stack has been connected");
}

I know I can use the function M5.Lcd.setCursor(); but I would like it to center my text according to its size ????
Thanks

use:
setTextDatum(uint8_t datum);

and available options:

Thank you so much, I did'nt see this function
But where should I put the function in my code?

void Display_WiFi_Connected() {
M5.Lcd.clear(BLACK);
M5.Lcd.setTextSize(2);
M5.Lcd.print("M5Stack has been connected");
}

Try this:

M5.Lcd.drawCentreString("your string", x, y, font);

So your code should be:

M5.Lcd.drawCentreString("M5Stack has been connected", 160, 120, 2);

to write a string size 2 on the center of the screen.

You also have the option to write a right aligned string.

I love reading C++ headers :)

For safe use in the future, better way is:

void Display_WiFi_Connected() {
  M5.Lcd.clear(BLACK);
  M5.Lcd.setTextDatum(CC_DATUM);
  M5.Lcd.drawString("M5Stack has been connected", 160, 120, 2);
}

because drawCentreString is marked as deprecated

@reaper7 @Calin Thanks mens
but my text was not center in my display

M5.Lcd.drawString("M5Stack has been connected", 160, 120, 2);

I think it's because of 160 and 120 values.
I would like my text to be centered in height and width.

[reaper7]

what is your screen orientation? landscape or portrait ??
where is your text?
try to swap values 160 with 120 for portrait mode
or use this instead:

M5.Lcd.drawString("M5Stack has been connected", (int)(M5.Lcd.width()/2), (int)(M5.Lcd.height()/2), 2);

which calculates values for current orientation.

I do not have hw for tests
