setWideTextAction() not having desired effect

[Tuoman]

Hi,

I try to use setWideTextAction() to wrap my long text into new lines as it goes over screen.

However, setWideTextAction does not seem to do anything.

What I have done:

-disable Auto-size and set text area size within screen limits (to generate code below)

-set Ellipsis character for this typography to *

-use code:

textPopup.setPosition(29, 0, 180, 160);
 textPopup.setColor(touchgfx::Color::getColorFrom24BitRGB(207, 207, 207));
 textPopup.setLinespacing(0);
 textPopup.setTypedText(touchgfx::TypedText(T_SINGLEUSEID228));
 
 
 textPopup.setWideTextAction(WIDE_TEXT_CHARWRAP);
 textPopup.invalidate();
 textPopup.resizeToCurrentText();
 textPopup.resizeHeightToCurrentText();
 textPopup.invalidate();

There is no ellipsis character, no newlines, the text just prints over the borders like it was not there.

How to use this?

Thanks!

You've just resized to Current Text, so naturally there won't be any wrapping. The textarea is now as long as the text and requires no wrapping.

Oh right, didn't realize that it will cut the text.

Thanks, just saved me many hours, worked immediately!

Awesome! :) No problem.

Haha. No problem. If there's a trap, then there's probably something to be improved.
