\hypertarget{tutorial_edje_swallow2}{}\label{tutorial_edje_swallow2}\index{Swallow example 2@{Swallow example 2}}
This example will show you how to load an image using evas and fill a swallow with it. It\textquotesingle{}s basically almost like the last example, but with a minor change.

This variables are used to store the name of the image that is going to be used, the path to it and a variable that will store the error cause if something goes wrong.

Here it is\+:  
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\ \ \ \textcolor{keyword}{const}\ \textcolor{keywordtype}{char}\ \ *edje\_file\ =\ PACKAGE\_DATA\_DIR\textcolor{stringliteral}{"{}/swallow.edj"{}};}
\DoxyCodeLine{\ \ \ \textcolor{keyword}{const}\ \textcolor{keywordtype}{char}\ \ *img\_file\ =\ PACKAGE\_SOURCE\_DATA\_DIR\textcolor{stringliteral}{"{}/bubble.png"{}};}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Evas__Image_ga17a0211044defa51aa3ceaadaa4e53c2}{Evas\_Load\_Error}}\ err;}

\end{DoxyCodeInclude}


Then we load the image with this command\+:


\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\ \ \ img\ =\ \mbox{\hyperlink{group__Evas__Object__Image_gafb52be265f315186a28d43af2d559ec6}{evas\_object\_image\_filled\_add}}(evas);}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Evas__Object__Image_gac2e588476b16b04f85ca9a594c140c1d}{evas\_object\_image\_file\_set}}(img,\ img\_file,\ NULL);}

\end{DoxyCodeInclude}
 To check if we had some problem we use\+:


\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\ \ \ err\ =\ \mbox{\hyperlink{group__Evas__Object__Image_ga10a0117fbd14e665a988cd4913c324d9}{evas\_object\_image\_load\_error\_get}}(img);}
\DoxyCodeLine{}
\DoxyCodeLine{\ \ \ \textcolor{keywordflow}{if}\ (err\ !=\ \mbox{\hyperlink{group__Evas__Image_gga17a0211044defa51aa3ceaadaa4e53c2a016233a6ae27765a3aa2759753c112ac}{EVAS\_LOAD\_ERROR\_NONE}})}
\DoxyCodeLine{\ \ \ \{}
\DoxyCodeLine{\ \ \ \ \ \ fprintf(stderr,\ \textcolor{stringliteral}{"{}could\ not\ load\ image\ '\%s'.\ error\ string\ is\ \(\backslash\)"{}\%s\(\backslash\)"{}\(\backslash\)n"{}},}
\DoxyCodeLine{\ \ \ \ \ \ \ \ \ \ \ \ \ \ img\_file,\ \mbox{\hyperlink{group__Evas__Utils_gaa067ec9b15e558d510a7ac373f700348}{evas\_load\_error\_str}}(err));}
\DoxyCodeLine{\ \ \ \ \ \textcolor{keywordflow}{goto}\ shutdown\_edje;}
\DoxyCodeLine{\ \ \ \}}

\end{DoxyCodeInclude}
 Now we are going to swallow it and check if worked. If you notice we are using "{}part\+\_\+one"{} as argument. We do this because we must explicit what part of our .edc file we want to swallow\+:


\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Edje__Object__Part_ga97d1419f89bff20ba971e47c78641271}{edje\_object\_part\_swallow}}(edje\_obj,\ \textcolor{stringliteral}{"{}part\_one"{}},\ img);}
\DoxyCodeLine{}
\DoxyCodeLine{\ \ \ obj\ =\ \mbox{\hyperlink{group__Edje__Object__Part_gabbb9c38b34a9d4ca193eac7bf552cf59}{edje\_object\_part\_swallow\_get}}(edje\_obj,\ \textcolor{stringliteral}{"{}part\_one"{}});}
\DoxyCodeLine{}
\DoxyCodeLine{\ \ \ \textcolor{keywordflow}{if}(obj\ ==\ img)}
\DoxyCodeLine{\ \ \ \ \ \ printf(\textcolor{stringliteral}{"{}Swallowing\ worked!\(\backslash\)n"{}});}

\end{DoxyCodeInclude}
 The example\textquotesingle{}s window should look like this picture\+:

  
\begin{DoxyImageNoCaption}
  \mbox{\includegraphics[width=\textwidth]{swallow2final}}
\end{DoxyImageNoCaption}


The complete .edc file\+: 
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{collections\ \{}
\DoxyCodeLine{\ \ \ group\ \{}
\DoxyCodeLine{\ \ \ \ \ \ name:\ "{}example\_group"{};}
\DoxyCodeLine{\ \ \ \ \ \ max:\ 500\ 500;}
\DoxyCodeLine{\ \ \ \ \ \ min:\ 50\ 50;}
\DoxyCodeLine{}
