problems with using drawString() to Displays a variable-length string

[baloyou]

hello, bodmer

i have a problems about drawString()

it's normal.

tft.drawString("12345",0,0);

but ,when i display "1234",The last 5 entered did not disappear

tft.drawString("1234",0,0);

I can only type this way(add a space after 4)

tft.drawString("1234 ",0,0);

Is there a better way?

thanks!!

Use the tft.setTextPadding(w) to define the width in pixels of the area to be blanked.
