This page is meant for developers who are totally new enlightment and wish to have the simplest examples possible. These are my first steps to getting started and are tested on the host machine. This page does not describe howto setup a build environment or how to deploy on openmoko.

Compiling edj files

Edje files are compiled with the edje_cc command, eg: edje_cc edje_file.edc


Simple box with margin

Python source:box_margin.py

#!/usr/bin/env python

import evas
import ecore
import ecore.evas
import edje
#import edje.decorators
import sys
import os

ee = ecore.evas.SoftwareX11(w=480, h=640)
edje_file = os.path.join(os.path.dirname(sys.argv[0]),"box_margin.edj")

c = edje.Edje(ee.evas,file=edje_file,group="test")
c.size = ee.evas.size

c.show()
ee.show()
ecore.main_loop_begin();

Edje source: box_margin.edc

collections {
   group {
      name: "test";
      	parts {
	    part {
	       name: "main";
	       type: RECT;
	       mouse_events: 0;
	       description {
	          state: "default" 0.0;
	          color: 128 255 255 255;
	          rel1 {
	             relative: 0.0 0.0;
	             offset: 10 10;
	          }
	          rel2 {
	              relative: 1.0 1.0;
	              offset: -10 -10;
	          }
	       }
	    }
        }
    }
}

Relative box position

This examples show to boxes where left upper corner of one box is set at the right bottom corner of the other.

Image

Note you also need an image 'image.png' which must be located in the same directory as image.edc.

c = edje.Edje(ee.evas,file=edje_file,group="test")
c.size = ee.evas.size

c.show()
ee.show()
ecore.main_loop_begin();

Edje source: image.edc

images {
    image: "image.png" COMP;

                   rel2 {
                      relative: 0.75 0.75;
                      offset: 0 0;

                }
            }
        }

}

Signals

Types of signals

* Handle signal inside edc, e.g: program: "button_hot";
* Handle event directly within the python code, e.g: c.signal_callback_add("mouse,clicked,1","button1",button_clicked)
* Resize callback, e.g: ee.callback_resize = resize_callback
* Custom signal emitted in edc program, e.g: 
 action: SIGNAL_EMIT "button_clicked_signal" "button1" and
 c.signal_callback_add("button_clicked_signal","button1",button_clicked_signal)

Personal tools

This page is meant for developers who are totally new enlightment and wish to have the simplest examples possible. These are my first steps to getting started and are tested on the host machine. This page does not describe howto setup a build environment or how to deploy on openmoko.

* Add proper openmoko initialization example.

Compiling edj files

Edje files are compiled with the edje_cc command, eg: edje_cc edje_file.edc

c = edje.Edje(ee.evas,file=edje_file,group="test")
c.size = ee.evas.size

c.show()
ee.show()
ecore.main_loop_begin();
