Graphics, Figures & Tables ⇒ Captions: Tricky Underlining

[generator]

I'm attempting to create custom float captions (for custom floats). Ordinarily, I might use a regular Figure to display a figure. In this case, the caption might display as:

Figure 1: A figure.

However, I want to underline the portion to the left of the colon. This would look like:

Figure 1: A figure.

I've come close to doing this. I can use

Code: Select all

\floatname{ColumnFigure}{\underline{Figure}}

which underlines the word "Figure".

Then, I can also use

Code: Select all

\renewcommand{\theColumnFigure}{\underline{\arabic{ColumnFigure}}}

which underlines the 1. I'd like to underline everything except the caption description. Can someone please help?

For underlining captions see http://www.latex-community.org/forum/vi ... 00&start=0

Without underlining the caption text nor the colon, that gives something like:

Code: Select all

\documentclass{article} 
\usepackage{ulem}
\usepackage{caption}[2007/09/01] % needs v3.1 or newer

\DeclareCaptionLabelFormat{underlcap}{\uline{#1 #2}}

\captionsetup[figure]{labelformat=underlcap}

\begin{document}

\begin{figure}[!ht]
  \centering
  \rule{3cm}{4cm}% to simulate an actual figure
  \caption{test figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure}
  \label{fig:test}
\end{figure}

\end{document}

I've found a way to do this without using the "ulem" package; use math mode, and "underline" some "text" in math mode.

Code: Select all

\documentclass{article} 
\usepackage{caption}[2007/09/01] % needs v3.1 or newer

%THE NEWLY REDONE TEXT FOLLOWS:
\DeclareCaptionLabelFormat{underlcap}{$\underline{\text{#1 #2}}$}
\captionsetup[figure]{labelformat=underlcap}

\begin{document}

\begin{figure}[!ht]
  \centering
  \rule{3cm}{4cm}% to simulate an actual figure
  \caption{test figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure figure}
  \label{fig:test}
\end{figure}

\end{document}
