Escape and Control Characters with text()

in Programming Questions • 8 months ago

I'm trying to use the control characters \n and \t with text() and it just seems to ignore them. Is there something special I have to do to make control characters work?

An example would be:

text("Raw Value\tReal Value\n" + boxText, xPos + 5, yPos + 15);

I'm using Processing 2.0b7.

Thanks.

Well, '\t' doesn't work, but '\n' does @ Processing v1.5.1.

I did more testing and figured out that 2.0b7 does the same. '\t' does not work, but '\n' does. Thanks for the answer. I'll just work around the lack of tab control character support.

\t seems to work in println() but not in text()

you have to split your line

text("Raw Value\tReal Value\n" + boxText, xPos + 5, yPos + 15);

into

int tabDistance = 40;
text("Raw Value", xPos + 5, yPos + 15);
text("Real Value\n" + boxText, xPos + 5 + tabDistance, yPos + 15);

you could also write a function textTab() that takes
text,x,y as parameters as text() does and
does a split() at \t
the resulting Array A can be shown with a for-loop
with each loop you increase x by tabDistance.

for i....................
text ( A[i], x, y );
x+=tabDistance;

The function could also calculate the value for tabDistance

by checking what is the textWidth() of the elements before that column or
by checking what is the longest in column 1 (when you give all rows as an array to function) and add 15 or so to textWidth() of it
