Easy way of determining spacing of lines of text

[Wibbs]

Hi all,

Just wanted to ask a quick question.  I'm currently implementing the GUI for my game, and am working out how to deal with multiple lines of text.  Given that the height of a String2D varies depending on the characters in the string, is there an easy way of determining the vertical spacing required to ensure that lines of text are evenly spaced for a given font and font size?  

The way I'm thinking of doing it at the moment, is to use a test string containing the highest and lowest characters for a particular font to establish the largest height a String2D could have, but this seems a tad cumbersome.  Is there an easier way?

Thanks,

Wibbs

In SFML 1, the line spacing is simply the character size of the String2D.

In SFML 2, the line spacing is given by the Font.GetLineSpacing function.

In both cases it is a constant, it never depends on the characters in the string.

Hi again,

I'm using 1.5 coz I don't want to have to deal with the regular updates to the version 2 code base at the moment.

I'm working out the String2D height by calling .GetRect() and taking the height from the resulting FloatRect.  When I do this for different strings, it gives different heights.  Am I doing this wrong then, because this is the only way I can see of getting a height measurement for the String2D?

Thanks,

This is not wrong, when you call GetRect().Height you get the actual height of the string. When you use the the character size, you have a constant number which is the maximum height that a character can have. Use the one that you need

Ah, ok I think I've got what you mean. So, the size I specify when I create the String2D object gives the maximum height of any text entered?

Yes.
