How many lines were written?

[Oli Ullmann]

Hello everyone :-)

If I use Graphics.drawMultiLineText(), is there any way to find out how many lines the written text needs?

Thank you very much
Oli

@Oli-Ullmann since you need to use \n, you can use a string variable which you're then plugging into the method call (as opposed to just writing it directly in the argument) and simply count the number of backslashes in the string

@aaronventure I think with multiline text it automatically splits the text without the need for a return character.

@d-healey but you can use it, and then use it to count the number of lines.

@aaronventure But the point of using drawMultilineText is you don't know how many lines you want - you don't know where you need to break, you want it to happen automatically based on the size of the rectangle and font.

If you're manually putting in line breaks then you don't need to count them because you know how many you have, and you should probably use the markdown renderer instead.

@d-healey You're completely right, somehow I missed the point.

Hmm, there's Graphics.getStringWidth(), you can put in your string, get the width and divide it by the text area width. Though it won't break the words properly...

Maybe you can come up with an algo that loops through the string checking the length word by word, and when the total width at that point becomes more than maxWidth of the text method, then you can guess that it'll break the line at that word, and start counting the string again from that word onward until you get to another point where you have more width than maxWidth.

@d-healey
Thank you. I will try the markdown renderer.

@aaronventure
There is also Engine.getStringWidth. I had also considered solving the problem with a bit of math. I probably won't be able to avoid it. Thanks for your ideas! :-)

[d.healey]

@Oli-Ullmann Perhaps there is another solution, why do you want to know the number of lines?

[aaronventure]

@Oli-Ullmann yes but the Graphics method takes in your current font for accurate string width
