Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje.
Note that embryo wont be used, but I'm not sure yet if you can build edje without it.

18@section intro What is Edje?
19
20Edje is a complex graphical design & layout library.
21
22It doesn't pretend to do containing and regular layout like a widget
23set, but it is the base for such components. Based on the requirements
24of Enlightenment 0.17, Edje should serve all the purposes of creating
25visual elements (borders of windows, buttons, scrollbars, etc.) and
26allow the designer the ability to animate, layout and control the look
27and feel of any program using Edje as its basic GUI constructor. This
28library allows for multiple collections of Layouts in one file,
29sharing the same image and font database and thus allowing a whole
30theme to be conveniently packaged into 1 file and shipped around.
31
32Edje separates the layout and behavior logic. Edje files ship with an
33image and font database, used by all the parts in all the collections
34to source graphical data. It has a directory of logical part names
35pointing to the part collection entry ID in the file (thus allowing
36for multiple logical names to point to the same part collection,
37allowing for the sharing of data between display elements). Each part
38collection consists of a list of visual parts, as well as a list of
39programs. A program is a conditionally run program that if a
40particular event occurs (a button is pressed, a mouse enters or leaves
41a part) will trigger an action that may affect other parts. In this
42way a part collection can be "programmed" via its file as to hilight
43buttons when the mouse passes over them or show hidden parts when a
44button is clicked somewhere etc. The actions performed in changing
45from one state to another are also allowed to transition over a period
46of time, allowing animation. Programs and animations can be run in
47"parallel".
48
49This separation and simplistic event driven style of programming can produce
50almost any look and feel one could want for basic visual elements. Anything
51more complex is likely the domain of an application or widget set that may
52use Edje as a convenient way of being able to configure parts of the display.
53
54For details of Edje's history, see the \ref history section.
55
56
57@section requirements What does Edje require?
58
59Edje requires fairly little on your system. to use the Edje runtime library
60you need:
61
62 - Evas (library)
63 - Ecore (library)
64 - Eet (library)
65 - Embryo (library)
66 - Eina (library)
67 - Lua 5.1 (library)
68
69Evas needs to be build with the JPEG, PNG and EET image loaders enabled at a
70minimum. You will also need the buffer engine (which requires the
71software_generic engine) as well.
72
73Ecore needs the ECORE, ECORE_EVAS and ECORE_X modules built at a minimum.
74It's suggested to build all the Ecore modules. You will beed the Buffer
75engine support built into Ecore_Evas for edje?_cc to function.
76
77
78@section compiling How to compile and test Edje
79
80Now you need to compile and install Edje.
81
82@verbatim
83 ./configure
84 make
85 sudo make install
86@endverbatim
87
88You now have it installed and ready to go, but you need input
89data. There are lots of examples in SVN, the best one is
90Enlightenment's own theme file.
91
92You may use different tools to edit and view the generated ".edj"
93files, for instance:
94
95 - edje_player (provided by Edje)
96 - editje (http://trac.enlightenment.org/e/wiki/Editje)
97 - edje_viewer (http://trac.enlightenment.org/e/wiki/Edje_Viewer)
98
99
100@section details So how does this all work?
101
102Edje internally holds a geometry state machine and state graph of what is
103visible, not, where, at what size, with what colors etc. This is described
104to Edje from an Edje .edj file containing this information. These files can
105be produced by using edje_cc to take a text file (a .edc file) and "compile"
106an output .edj file that contains this information, images and any other
107data needed.
108
109The application using Edje will then create an object in its Evas
110canvas and set the bundle file to use, specifying the @b group name to
111use. Edje will load such information and create all the required
112children objects with the specified properties as defined in each @b
113part of the given group. See the following annotated example:
114
115@code
116
117#include <Eina.h>
118#include <Evas.h>
119#include <Ecore.h>
120#include <Ecore_Evas.h>

127{

130 edje = edje_object_add(canvas);
131 if (!edje)

133 EINA_LOG_CRIT("could not create edje object!");
134 return NULL;
135 }
136
137 if (!edje_object_file_set(edje, "edje_example.edj", "my_group"))
138 {
139 int err = edje_object_load_error_get(edje);
140 const char *errmsg = edje_load_error_str(err);
141 EINA_LOG_ERR("could not load 'my_group' from edje_example.edj: %s",
142 errmsg);
143
144 evas_object_del(edje);
145 return NULL;
146 }
147
148 if (text)
149 {
150 if (!edje_object_part_text_set(edje, "text", text))
151 {
152 EINA_LOG_WARN("could not set the text. "
153 "Maybe part 'text' does not exist?");
154 }
155 }
156

158 evas_object_resize(edje, WIDTH, HEIGHT);
159 evas_object_show(edje);
160 return edje;
161}
162
163int main(int argc, char *argv[])
164{
165 Ecore_Evas *window;
166 Evas *canvas;

180 return -1;

222 offset: 0 0;
223 }
224 rel2 { // bottom-right point at (WIDTH * 1.0 - 1, HEIGHT * 1.0 - 1)
225 relative: 1.0 1.0;
226 offset: -1 -1;
227 }
228 }
229 }
230
231 part {
232 name: "text";
233 type: TEXT;
234 mouse_events: 1; // we want to change the color on mouse-over
235
236 // 2 states, one "default" and another "over" to be used
237 // on mouse over effect
238
239 description {

246 relative: 0.1 0.2;
247 offset: 5 10;
248 }
249 rel2 { // bottom-right at (WIDTH * 0.9 - 6, HEIGHT * 0.8 - 11)
250 relative: 0.9 0.8;
251 offset: -6 -11;
252 }
253
254 // define text specific state details
255 text {
256 font: "Sans"; // using fontconfig name!
257 size: 10;
258 text: "hello world";
259 }
260 }
261
262 description {
263 state: "over" 0.0;
264 inherit: "default" 0.0; // copy everything from "default" at this point
265
266 color: 0 255 0 255; // override color, now it is green
267 }
268 }
269
270 // do programs to change color on text mouse in/out (over)
271 programs {
272 program {
273 // what triggers this program:
274 signal: "mouse,in";
275 source: "text";
276
277 // what this program does:
278 action: STATE_SET "over" 0.0;
279 target: "text";
280
281 // do the state-set in a nice interpolation animation
282 // using linear time in 0.1 second
283 transition: LINEAR 0.1;
284 }
285
286 program {
287 // what triggers this program:
288 signal: "mouse,out";
289 source: "text";
290
291 // what this program does:
292 action: STATE_SET "default" 0.0;
293 target: "text";
294
295 // do the state-set in a nice interpolation animation
296 // using linear time in 0.1 second
297 transition: LINEAR 0.1;
298 }
299 }
300 }
301 }
302}
303@endcode
304
305
306One should save these files as edje_example.c and edje_example.edc then:
307@verbatim
308gcc -o edje_example edje_example.c `pkg-config --cflags --libs eina evas ecore ecore-evas edje`
309edje_cc edje_example.edc
310
311./edje_example "some text"
312@endverbatim
313
314Although simple, this example illustrates that animations and state
315changes can be done from the Edje file itself without any requirement
316in the C application.
317
318Before digging into changing or creating your own Edje source (edc)
319files, read the @ref edcref.

321
322
323@section history Edje History
324
325It's a sequel to "Ebits" which has serviced the needs of Enlightenment
326development for early version 0.17. The original design parameters under
327which Ebits came about were a lot more restricted than the resulting
328use of them, thus Edje was born.
329
330Edje is a more complex layout engine compared to Ebits. It doesn't
331pretend to do containing and regular layout like a widget set. It
332still inherits the more simplistic layout ideas behind Ebits, but it
333now does them a lot more cleanly, allowing for easy expansion, and the
334ability to cover much more ground than Ebits ever could. For the
335purposes of Enlightenment 0.17, Edje was conceived to serve all the
336purposes of creating visual elements (borders of windows, buttons,
337scrollbars, etc.) and allow the designer the ability to animate,
338layout and control the look and feel of any program using Edje as its
339basic GUI constructor.
340
341Unlike Ebits, Edje separates the layout and behavior logic.
