libgdx：标签高度多行

Question

I have a Label object with a text in it...

Label label = new Label(text);

..and I get the height by...

label.pack();
GlyphLayout layout = label.getGlyphLayout();
float height = layout.height;

When I add them to a table I just said

Table t = new Table();
t.add(label).width(200).height(height); 

Currently I work on a chat window and each entry of the window is a Label containing a colored name and text, like...

Note: The debug lines are drawn. Please ignore the blue line, it's from another table in the scene

Now my question : The 1-liner has a glyphlayout height of 38 and the 3-liner 139 . Does someone know why there's such a big gap between the 2 entries resp. why the 3-liner height doesn't seem to be correct? No extra spacing / padding.

I would appreciate any ideas to solve this.

Answer 1

SOLVED: My post was incomplete, sorry. I set the width of the label before calling...

label.setWidth(x); // where x was < chatbox width
label.pack();

So the GlyphLayout assumed a width which was smaller than the actual chatbox width. The result is of course a bigger height...

Thanks a lot to the libgdx IRC, especially Tomski :)
