Multilinetext in beamercolorbox

Question

I'm try to customize a beamer theme with some additional text and logos. I added some pictures already and everything looks fine. Now I want to add a three line text in the head of a presentation. I changed my outer theme and added a beamercolorbox. I want to have something like:

          some text  ============
    some other text  =   LOGO   =
and again some text  ============

I added a beamercolorbox with the logo. Now I have some issues with the multiline text. If I do something like:

\begin{beamercolortext}[<options>]{<color>}
      line 1 \\
      line 2 \\
      line 3
\end{beamercolorbox}

I will just get a text in one line which looks like line 1 , line 2 , line 3. If I replace the \\ by \newline then I will get three lines. The problem is that I can't change the spacing. If I do \vspace{} then I shift the whole text and the space between the two lines doesn't change.

Is there a better way to add this three lines, maybe something beside beamercolorbox?

EDIT

Well. I using the beamercolorbox in a definition of an outer theme.

\defbeamertemplate*{headline}{split theme}
{%
  \leavevmode%
  \@tempdimb=10.7ex%
  %\@tempdimb=2.4375ex%
  \ifnum\beamer@subsectionmax<\beamer@sectionmax%
    \multiply\@tempdimb by\beamer@sectionmax%
  \else%
    \multiply\@tempdimb by\beamer@subsectionmax%
  \fi%
  \ifdim\@tempdimb>0pt%
    \advance\@tempdimb by 0ex%
    %\advance\@tempdimb by 1.125ex%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb,left]{section in     head/foot}%
      \hspace{1em}\vspace{0.7ex}\pgfuseimage{tu-logo}
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.5\paperwidth,ht=\@tempdimb,right]{section in   head/foot}%
      \begin{beamercolorbox}[wd=.2\paperwidth,ht=\@tempdimb,right]{title}
        test \\
        test \\
        test
      \end{beamercolorbox}
      \vspace{0.7ex}\pgfuseimage{iwm-logo}\hspace{1em}
     \end{beamercolorbox}
  \fi%
}

It's close to what is defined in the Warsaw theme. Please don't take the definition of spaces to serious. It's just an example and I wanted to make it work before I define all the spaces. My result for the following code will give me something like -- in the top right corner:

In places, where multi-line text doesn't work, you could try \parbox.

Also here it works with \\ if you would put the contents into a parbox. Alternatively, you could use \newline instead of \\. However, if you use \\ inside the parbox, you could specify optional spacing, such as \\[2pt].

Another approach is using a simple table in that box in the header, with adjusted \arraystretch value if desired, such as by

\begin{tabular}{@{}r@{}}

In all cases, increase the height of the beamercolorbox, this means the parameter ht in the argument of the beamercolorbox environment.
