Block over the content of a slide - Beamer

Postby alex-a » Tue Nov 24, 2009 3:01 pm

Hi all,

I'm not sure if this is the right place to ask this question, but here I go :)
I'm preparing a presentation using Beamer, and I'd like to place a "block" box over the content of a slide.

For example, consider this two-column slide frame:

  1. \begin{frame}{Frame title}
  2. \begin{columns}[c]
  3. \column{0.5\textwidth}
  4. \begin{itemize}
  5. \item[-] First item
  6. \item[-] Second item
  7. \end{itemize}
  9. \begin{block}{Hello!}<2->
  10. This is the block that I want to
  11. be over everything when I hit <Enter>! :)
  12. \end{block}
  14. \column{0.5\textwidth}
  15. \begin{figure}
  16. \flushleft
  17. \includegraphics{image.png}
  18. \end{figure}
  19. \end{columns}
  20. \end{frame}

I want to put the "Hello! block" on the middle of the slide, over the text and the image. Is there a way to do that, like specifying a (x,y) position?

I googled this "problem", but I couldn't find any solution. Apparently, I'm the first one who wants to do that :D

I appreciate any help. Thanks in advance!

Hi there,

What do you mean by a block??? Do you want to add a simple itemize square figure, that you can define in a list environment??? Otherwise, you will have to be more precise on your request, because I don't understand.

In Beamer, a "block" is a framed text with a title.

Here is an example (slide 50):

I just want this framed text to cover the text/figures/lists/whatever the slide has when I forward one slide.
You know, I just want to emphasize something in my presentation, and I think this would be the best way.

Thanks for your reply ;)
