I have the following rectangle:

documentclass[tikz,11pt]{standalone}

usepackage{pgfplots} 

usetikzlibrary{shapes,fit,chains,positioning,patterns}  

usepackage{xcolor}

usepackage{graphicx}



pgfplotsset{compat=newest}



begin{document}

begin{tikzpicture}

fill[blue!8!white] (0.3,1.1) -- (0.3,0.68) -- (1.2,0.68) -- (1.2,1.1);

filldraw[pattern = north east lines,rounded corners=8pt, blue!8!white,draw=black] (0.3,1.1) -- (0.3,3.45) -- (1.2,3.45) -- (1.2,1.1);

draw[dashed] (0.3,1.1) -- (0.3,0.68);

draw[dashed] (1.2,1.1) -- (1.2,0.68);

filldraw[rounded corners=8pt, blue!8!white,draw=black] (0.3,0.68) -- (0.3,-0.3) -- (1.2,-0.3) -- (1.2,0.68);

node[draw=none,fill=none] at (0.75,1.575) {footnotesize{text{Q/C}}};

end{tikzpicture}

end{document}

rather than a continuous fill, how can I have a striped fill? Additionally I want the pattern shading to leave a rounded white rectangle about the text node in the centre.

You can use postaction for the pattern. I also cleaned up a bit.

documentclass[tikz,11pt]{standalone}

usetikzlibrary{patterns}  

begin{document}

begin{tikzpicture}

path[postaction={pattern = north east lines},rounded corners=8pt,

fill=blue!8!white] (0.3,-0.3) rectangle (1.2,3.45)

node[midway,font=footnotesize,fill=white,rounded corners=2pt,inner sep=1.5pt]  {Q/C};

draw[dashed] (0.3,1.1) -- (0.3,0.68) (1.2,1.1) -- (1.2,0.68);

draw[rounded corners=8pt] (0.3,1.1) |- (0.75,3.45)

(1.2,1.1) |- (0.75,3.45) 

(0.3,0.68) |- (0.75,-0.3)

(1.2,0.68)|- (0.75,-0.3);

end{tikzpicture}

end{document}

This is a style Sid grid which allows you to have a fully customizable pattern. It uses a path picture, which takes a few milliseconds more to compile, but is way more flexible, and can be transformed and so on.

documentclass[tikz,11pt]{standalone}

usetikzlibrary{patterns,calc}

pgfkeys{/Sid/.cd,

grid/.style={draw=black,double=blue!8!white,line width=0.4pt,double distance=2pt},

distance/.initial=6pt,

}

tikzset{Sid grid/.style={/utils/exec=pgfkeys{/Sid/.cd,#1},

path picture={

path[/Sid/grid] let p1=($(path picture bounding box.north east)-(path picture bounding

box.south west)$),n1={int((x1+y1)/pgfkeysvalueof{/Sid/distance})} in 

pgfextra{pgfmathsetmacromynmax{n1}}

foreach XX in {1,...,mynmax}

{ 

([xshift={-y1-2pt+XX*pgfkeysvalueof{/Sid/distance}},yshift=-2pt]path picture bounding box.south west)

--

([xshift=XX*pgfkeysvalueof{/Sid/distance}+2pt,yshift=2pt]path picture bounding box.north west)

};

}}}



begin{document}

begin{tikzpicture}

pgfmathsetmacro{mh}{6/sqrt(2)}

path[rounded corners=8pt,Sid grid] (0.3,-0.3) rectangle (1.2,3.45)

node[midway,font=footnotesize,fill=white,rounded corners=2pt,inner sep=1.5pt]  {Q/C};

draw[dashed] (0.3,1.1) -- (0.3,0.68) (1.2,1.1) -- (1.2,0.68);

draw[rounded corners=8pt] (0.3,1.1) |- (0.75,3.45)

(1.2,1.1) |- (0.75,3.45) 

(0.3,0.68) |- (0.75,-0.3)

(1.2,0.68)|- (0.75,-0.3);

Like this ?

documentclass[tikz,11pt,border=5mm]{standalone}

usepackage{pgfplots} 

usetikzlibrary{shapes,fit,chains,positioning,patterns}  

usepackage{xcolor}

usepackage{graphicx}



pgfplotsset{compat=newest}



begin{document}

begin{tikzpicture}

fill[blue!8!white] (0.3,1.1) -- (0.3,0.68) -- (1.2,0.68) -- (1.2,1.1);

filldraw[blue!8!white,pattern = north east lines,rounded corners=8pt, draw=black] (0.3,1.1) -- (0.3,3.45) -- (1.2,3.45) -- (1.2,1.1);
