How to change Warsaw theme's frametitle height in Latex? - latex

Question

I am making some changes in Warsaw theme. I want to increase the height of the frametitle. I have used the following code, because I did not want the navigation part from the the headline. Now I need to increase the height of the frame title without increasing the font size. Please see the commands I used:
\setbeamertemplate{headline}{%
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=\paperwidth,ht=0 ex,dp=0ex]{palette quaternary}%
\end{beamercolorbox}%
}
}

You could adjust the frametitle template. I marked the line to change with % <-
\documentclass{beamer}
\usetheme{Warsaw}
\setbeamertemplate{headline}{}
\makeatletter
\setbeamertemplate{frametitle}{%
\nointerlineskip%
\vskip-2pt%
\hbox{\leavevmode
\advance\beamer#leftmargin by -12bp%
\advance\beamer#rightmargin by -12bp%
\beamer#tempdim=\textwidth%
\advance\beamer#tempdim by \beamer#leftmargin%
\advance\beamer#tempdim by \beamer#rightmargin%
\hskip-\Gm#lmargin\hbox{%
\setbox\beamer#tempbox=\hbox{\begin{minipage}[b]{\paperwidth}%
\vbox{}\vskip-.75ex%
\vspace{2cm}% <- change here to whatever you want
\leftskip0.3cm%
\rightskip0.3cm plus1fil\leavevmode
\usebeamercolor[fg]{frametitle}\usebeamerfont{frametitle}\strut\insertframetitle\strut\par%
\ifx\insertframesubtitle\#empty\else%
{\usebeamerfont*{framesubtitle}{\usebeamercolor[fg]{framesubtitle}\insertframesubtitle}\strut\par}%
\fi%
\nointerlineskip
\vbox{}%
\end{minipage}}%
\beamer#tempdim=\ht\beamer#tempbox%
\advance\beamer#tempdim by 2pt%
\begin{pgfpicture}{0pt}{0pt}{\paperwidth}{\beamer#tempdim}
\usebeamercolor{frametitle right}
\pgfpathrectangle{\pgfpointorigin}{\pgfpoint{\paperwidth}{\beamer#tempdim}}
\pgfusepath{clip}
\pgftext[left,base]{\pgfuseshading{beamer#frametitleshade}}
\end{pgfpicture}
\hskip-\paperwidth%
\box\beamer#tempbox%
}%
\hskip-\Gm#rmargin%
}%
\nointerlineskip
\vskip-0.2pt
\hbox to\textwidth{\hskip-\Gm#lmargin\pgfuseshading{beamer#topshade}\hskip-\Gm#rmargin}
\vskip-2pt
}
