This is a simple example in which we create a rect and swallow it.

Focusing on the relevant parts of the code we go right to the creation of our rectangle. It should be noted that we don\textquotesingle{}t resize or show our rect, that is because when an object is swallowed it\textquotesingle{}s geometry and visibility is controlled by the theme\+: 
\begin{DoxyCodeInclude}
   rect = \mbox{\hyperlink{group__Evas__Object__Rectangle_ga4d80fc32ad1cac28428cebd65d746751}{evas\_object\_rectangle\_add}}(\mbox{\hyperlink{namespaceevas}{evas}});
   \mbox{\hyperlink{group__Evas__Object__Group__Basic_gae34bdcfd7f5100151f6ea8ef4a392949}{evas\_object\_color\_set}}(rect, 255, 0, 0, 255);
   edje\_object\_part\_swallow(edje\_obj, \textcolor{stringliteral}{"part\_one"}, rect);

\end{DoxyCodeInclude}


The other bit of code that is relevant to us now is our check that the swallow worked\+: 
\begin{DoxyCodeInclude}

   obj = edje\_object\_part\_swallow\_get(edje\_obj, \textcolor{stringliteral}{"part\_one"});
   \textcolor{keywordflow}{if}(obj == rect)
      printf(\textcolor{stringliteral}{"Swallowing worked!\(\backslash\)n"});

\end{DoxyCodeInclude}
