Document Classes ⇒ [Listings]Multiline caption in floating listing environment

[-Robin-]

I was trying to have a multiline caption in the listing environment, but I can't get it working the way it should.
I found a suggestion on this forum that including the caption package should do it, but it didn't help me in a listing environment

Code: Select all

\documentclass{book}
\usepackage{listings}
\usepackage{caption}
\begin{document}
\lstinputlisting[float, caption={testcaption\\ multiline}, label={testlabel}]{sample.java}
\end{document}

Replacing the \\ by \newline generates a new line, but then the alignment is broken

Since Java files are not allowed to be attachted, I included the code in a code environment

Code: Select all

class Sample{
	private Object fVariable = new Object();

	public static void main(String[] args){
		int w = 0;
		boolean bool = true;
		for(int i = 0; i<w; i++){
			if(bool){
				System.out.println("Testing of the listing package");
			} else{
				/* Some blockcomments
				 * More comments
				 * And the last line of comments
				 */
				System.out.println("This code makes absolutely no sense");
			}
		}
	}
	public Object getVariable(){
		//Some testcomment
		return fVariable;
	}
}

Any suggestions

Try this:

Code: Select all

\newsavebox{\captionbox}
\sbox{\captionbox}{\parbox[t]{\linewidth}{A very, very long caption here}}
\lstinputlisting[float, caption=\usebox{\captionbox}, label={testlabel}]{sample.java}

Thanks. This solves my problem.

I had experimented myself with mbox but then it was impossible to set the width

Line breaks are disabled inside \mbox, so it would be useless. Just for your records, if you want to set the width, use \makebox[width]{text}.
