What I want is something like this:
------------- bla bla bla | ---------------------------------------------------
Here bla bla bla should be in white and the the box surrounding it should be filled with black. Then, a rule in black should drawn aligned exactly with the bottom of the box till the right margin of the page.
Write in ERT
\colorbox{black}{\textcolor{white}{bla bla bla}}\hrulefillor to have the rule exactly at the bottom of the box
\raisebox{1mm}{%
\colorbox{black}{\textcolor{white}{bla bla bla}}%
}\hrulefillPlay a bit with the unit of \raisebox, because it depends on the letter size.
