In this example, we illustrate how Edje signals and Edje messages work.

We place, in the canvas, an Edje object along with a {\bfseries{red}} border image to delimit its geometry. The object\textquotesingle{}s group definition is so that we have four parts\+:
\begin{DoxyItemize}
\item a blue rectangle, aligned to the right
\item a white rectangle, aligned to the left
\item a text part, aligned to the center
\item a clipper rectangle on the blue rectangle
\end{DoxyItemize}

The left rectangle is bound to a {\bfseries{color class}}, so that we can multiply its colors by chosen values on the go\+:

The {\ttfamily \#define\textquotesingle{}s} on the beginning will serve as message identifiers, for our accorded message interface between the code and the this theme file.

Let\textquotesingle{}s move to the code, then. After instantiating the Edje object, we register two {\bfseries{signal callbacks}} on it. The first one uses {\bfseries{globbing}}, making all of the wheel mouse actions over the left rectangle to trigger {\ttfamily \+\_\+mouse\+\_\+wheel}. Note that those kind of signals are generated {\bfseries{internally}} (and automatically) in Edje. The second is a direct signal match, to a (custom) signal we defined in the E\+DC, ourselves\+:

That second callback is on a signal we emit on the theme, where we just translate Edje {\ttfamily \char`\"{}mouse,move\char`\"{}} internal events to the custom {\ttfamily \char`\"{}mouse,over\char`\"{}} one. When that signals reaches the code, we are, besides printing the signals\textquotesingle{} strings, sending a {\bfseries{message}} back to the theme. We generate random values of color components and send them as an \#\+E\+D\+J\+E\+\_\+\+M\+E\+S\+S\+A\+G\+E\+\_\+\+I\+N\+T\+\_\+\+S\+ET message type\+:

In our theme we\textquotesingle{}ll be changing the {\ttfamily \char`\"{}cc\char`\"{}} color class\textquotesingle{} values with those integer values of the message, so that moving the mouse over the right rectangle will change the left one\textquotesingle{}s colors\+:

Now we\textquotesingle{}re also sending messages {\bfseries{from the Edje object}}, besides signals. We do so when one clicks with the left button over the left rectangle. With that, we change the text part\textquotesingle{}s text, cycling between 3 pre-\/set strings declared in the E\+DC. With each new text string attribution, we send a string message to our code, with the current string as argument\+:

To interact with the last missing feature -- emitting signals {\bfseries{from code}} -- there\textquotesingle{}s a command line interface to exercise it. A help string can be asked for with the \textquotesingle{}h\textquotesingle{} key\+:
