[2.1] sf::Text wrap at a specific X co-ord
« on: December 11, 2013, 03:03:08 pm »
hey, lets say I have a text like this:
        contentT.setPosition(xPos-170, yPos-70);

and it has a long piece of text(like ddddddddddddddddiwwwwwwwwwwwwwwwwwwwwwwwwwwwaaaaa) in it, the xPos and yPos are relative to the current object these are in, the whole container width is 349px

How could I now make the contentT, when drawed- do a line wrap at lets say xPos+170 ? and go to the next line at xPos-170 again?

You have to adapt the strings correspondingly. Either you insert "\n" characters or you use multiple sf::Text objects aligned below each other.

To know where to break your string, you have to sum up character widths until your threshold is reached. Have a look at the sf::Font and sf::Glyph classes, they provide you with the information you need.

Don't forget Text::findCharacterPos.
