\hypertarget{Example_Evas_Smart_Objects}{}\label{Example_Evas_Smart_Objects}\index{Evas object smart objects@{Evas object smart objects}}


In this example, we illustrate how to create and handle Evas smart objects.

A smart object is one that provides custom functions to handle clipping, hiding, moving, resizing, color setting and more on {\bfseries{child}} elements, automatically, for the smart object\textquotesingle{}s user. They could be as simple as a group of objects that move together (see \doxylink{group__Evas__Smart__Object__Clipped}{Clipped Smart Object}) or implementations of whole complex UI widgets, providing some intelligence (thus the name) and extension to simple Evas objects.

Here, we create one as an example. What it does is to control (at maximum) 2 child objects, with regard to their geometries and colors. There can be a "{}left"{} child and a "{}right"{} one. The former will always occupy the top left quadrant of the smart object\textquotesingle{}s area, while the latter will occupy the bottom right. The smart object will also contain an {\bfseries{internal}} decorative border object, which will also be controlled by it, naturally.

Here is where we add it to the canvas\+: 
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\ \ \ d.smt\ =\ evas\_smart\_example\_add(d.evas);}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Evas__Object__Group_ga335c8ee6eaeaac9710656af4f8b0db91}{evas\_object\_move}}(d.smt,\ WIDTH\ /\ 4,\ HEIGHT\ /\ 4);}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Evas__Object__Group_gacad94595f83580c18908cb3b69b08d1a}{evas\_object\_resize}}(d.smt,\ WIDTH\ /\ 2,\ HEIGHT\ /\ 2);}
\DoxyCodeLine{\ \ \ \mbox{\hyperlink{group__Evas__Object__Group__Basic_ga07208fcafd4739de606bc35fff684bf5}{evas\_object\_show}}(d.smt);}

\end{DoxyCodeInclude}
 The magic starts to happen in the {\ttfamily evas\+\_\+smart\+\_\+example\+\_\+add()} function, which is one in the example smart object\textquotesingle{}s defined {\bfseries{interface}}. These should be the functions you would export to the users of your smart object. We made three for this one\+:
\begin{DoxyItemize}
\item {\ttfamily evas\+\_\+smart\+\_\+example\+\_\+add()}\+: add a new instance of the example smart object to a canvas
\item {\ttfamily evas\+\_\+smart\+\_\+example\+\_\+remove()}\+: remove a given child of the smart object from it
\item {\ttfamily evas\+\_\+smart\+\_\+example\+\_\+set\+\_\+left()}\+: set the left child of the smart object
\item {\ttfamily evas\+\_\+smart\+\_\+example\+\_\+set\+\_\+right()}\+: set the right child of the smart object
\end{DoxyItemize}

The object\textquotesingle{}s creation takes place as\+:  
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\textcolor{comment}{/*\ add\ a\ new\ example\ smart\ object\ to\ a\ canvas\ */}}
\DoxyCodeLine{\mbox{\hyperlink{group__Evas__Object__Group_gabe5400fe3a79d3656d67e2fa8b78223f}{Evas\_Object}}\ *}
\DoxyCodeLine{evas\_smart\_example\_add(\mbox{\hyperlink{group__Evas__Canvas_ga58a46cee0f14304dd61439e9b85b925d}{Evas}}\ *evas)}

\DoxyCodeLine{\}}

\end{DoxyCodeInclude}
 Smart objects are defined by {\bfseries{smart classes}}, which are structs defining their interfaces, or {\bfseries{smart functions}} (see \doxylink{group__Evas__Smart__Group_ga7b9a6fa6a45368cab9f4b37d5b621e11}{Evas\+\_\+\+Smart\+\_\+\+Class}, the base class for any smart object). As you see, one has to use the \doxylink{group__Evas__Smart__Object__Group_ga6689aaee0f614404be7dc7c3d31a23e0}{evas\+\_\+object\+\_\+smart\+\_\+add()} function to instantiate smart objects. Its second parameter is what matters -- an \doxylink{Evas__Common_8h_a7cdfd1afece1cad64c413eb9a778ddbb}{Evas\+\_\+\+Smart} struct, which contains all the smart class definitions (smart functions, smart callbacks, and the like). Note, however, that {\ttfamily \+\_\+evas\+\_\+smart\+\_\+example\+\_\+smart\+\_\+class\+\_\+new()} seems not to be defined in our example\textquotesingle{}s code. That\textquotesingle{}s because it came from a very handy {\bfseries{helper macro}}\+:  
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\mbox{\hyperlink{group__Evas__Smart__Group_ga58dc94af6f064b39b2bf0155908fbe52}{EVAS\_SMART\_SUBCLASS\_NEW}}(\_evas\_smart\_example\_type,\ \_evas\_smart\_example,}
\DoxyCodeLine{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \mbox{\hyperlink{struct__Evas__Smart__Class}{Evas\_Smart\_Class}},\ \mbox{\hyperlink{struct__Evas__Smart__Class}{Evas\_Smart\_Class}},}
\DoxyCodeLine{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \mbox{\hyperlink{group__Evas__Smart__Object__Clipped_ga28133d16f3a1f8e3e71d3e80bb78df96}{evas\_object\_smart\_clipped\_class\_get}},\ \_smart\_callbacks);}

\end{DoxyCodeInclude}
What it does is to {\bfseries{subclass}} a given existing smart class, thus specializing it. This is very common and useful in Evas. There is a built-\/in smart object, the "{}clipped smart object"{}, which implements a behavior mostly desired by many other smart object implementors\+: it will clip its children to its area and move them along with it, on \doxylink{group__Evas__Object__Group_ga335c8ee6eaeaac9710656af4f8b0db91}{evas\+\_\+object\+\_\+move()} calls. Then, our example smart object will get that behavior for free.

The first argument to the macro,  
\begin{DoxyCodeInclude}{0}
\DoxyCodeLine{\textcolor{preprocessor}{\#define\ \_evas\_smart\_example\_type\ "{}Evas\_Smart\_Example"{}}}

\end{DoxyCodeInclude}
will define the new smart class\textquotesingle{} name. The second tells the macro what is the {\bfseries{prefix}} of the function it will be declaring with a {\ttfamily \+\_\+smart\+\_\+set\+\_\+user()} suffix. On this function, we may override/extend any desired method from our parent smart class\+:

 See that, as we\textquotesingle{}re inheriting from the clipped smart object\textquotesingle{}s class, we {\bfseries{must}} have their data struct as our first member. Other data of interest for us is a child members array and the border object\textquotesingle{}s handle. The latter is what is created in the last mentioned function. Note how to tell Evas the border will be managed by our smart object from that time on\+: {\ttfamily evas\+\_\+object\+\_\+smart\+\_\+member\+\_\+add(priv-\/\texorpdfstring{$>$}{>}border, o);}. The counterpart of this function is exemplified on the smart object\textquotesingle{}s interface function to remove children\+:

 At the end of that function we make use of an constant defined by the \doxylink{group__Evas__Smart__Group_ga58dc94af6f064b39b2bf0155908fbe52}{EVAS\+\_\+\+SMART\+\_\+\+SUBCLASS\+\_\+\+NEW}\+: {\ttfamily \+\_\+evas\+\_\+smart\+\_\+example\+\_\+parent\+\_\+sc}.

The {\ttfamily del}, {\ttfamily hide}, {\ttfamily show} and {\ttfamily resize} specializations are straightforward, we let the reader take a look at them below to check their behavior.

 This code will take place whenever the smart object itself is flagged "{}dirty"{}, i.\+e., must be recalculated for rendering (that could come from changes on its clipper, resizing, moving, etc). There, we make sure the decorative border lies on the edges of the smart object and the children, if any, lie on their respective quadrants.

After instantiating our smart object, we do some checks to exemplify some of the API on smart objects\+:

 Here we declare our array of smart callback descriptions, which has one element only, in this case. That callback will take place, as the name indicates, whenever the number of member objects in our smart object example instance changes.

 The code of the callback will just print how many member objects we have, which is an integer argument of the callback itself, as flagged by its description\+:

Use \textquotesingle{}l\textquotesingle{} and \textquotesingle{}r\textquotesingle{} keys, to create new rectangles and place them on the left ({\ttfamily evas\+\_\+smart\+\_\+example\+\_\+set\+\_\+left()}) or right ({\ttfamily evas\+\_\+smart\+\_\+example\+\_\+set\+\_\+right()}) spots of our smart object, respectively. The \textquotesingle{}w\textquotesingle{} command will remove all member objects from the smart object and delete them. The keyboard arrows will move the smart object along the canvas. See how it takes any child objects with it during its movement. The \textquotesingle{}d\textquotesingle{} and \textquotesingle{}i\textquotesingle{} keys will increase or decrease the smart object\textquotesingle{}s size -- see how it affects the children\textquotesingle{}s sizes, too. Finally, \textquotesingle{}c\textquotesingle{} will change the color of the smart object\textquotesingle{}s clipper (which is the exact internal clipper coming from a clipped smart object)\+:
