title: Emacs gdb speedbar in same window
body: <p>I am using emacs gdb with gdb-many-windows mode,
  I am noticing that the gdb watch expressions speedbar opens in a different window.</p>
  
  <p>I want to have it in the same window. I looked into <a href="http://www.emacswiki.org/emacs/SrSpeedbar" rel="nofollow">http://www.emacswiki.org/emacs/SrSpeedbar</a> which claimed to allow speedbar to open in the same window, i installed it and it works fine for the normal speedbar.</p>
  
  <p>But how do  i get it to work with the gdb watch expressions speedbar,
  is there any way i can get gdb watch expressions sppedbar to open in the same window by default (say as the 7th window in the GDB gui interface)?</p>
