Report 

First Activity : Learning the braille code
28th May 2011 :  A gist of my work during first week of google summer of code :

• Creating/adding an activity :Following number of quick steps inside gcompris cloned folder to get an empty python template running.
  
  

  make clean
  sh autogen.sh
  
  make
  sudo make install 
  
  sh createit.sh braille_alphabets
  make
  
  sh runit.sh braille_aplhabets-activity/
  
  



• Coding for Braille alphabets : My first braille activity learning the braille code is intended to make the kids familiar with braille code for alphabets ,symbols & numerals.It consists of two levels.The first half letters (A to M)are taught in the first level & next half in the next level.I have used mainly :-
  goocanvas.Ellipse : for creating a new canvas ellipse item
  goocanvas.Rect : for creating a new canvas rectangle item
  goocanvas.Text : a canvas item for displaying text
  A code snippet to show how to create an ellipse centered at (100.0, 100.0), with a horizontal radius of 50.0 and a vertical radius of 30.0. It is drawn with a red outline with a width of 5.0 and filled with blue:
  goocanvas.Ellipse(parent=root,
  center_x=100,
  center_y=100,
  radius_x=50,
  radius_y=30,
  stroke_color="red",
  fill_color="blue",
  line_width=5.0)
  
  A connect event to link the items to various signal events & functions.In the following line we call a function alphabet_A on button press event.
  ellipse.connect("button_press_event",self.alphabet_A,"ellipse")
  


• BrailleChar Module : This module contains a class BrailleChar which is used to display the letter being called via the object of class at specific coordinates & also checks two parameters : clickable & displayable which takes boolean values.I import this module in my braille_alphabets.py class as follows :-
  from BrailleChar import *
  brailleA = self.br_chr(x,y,letter,displayable,clickable)
  


• Inkscape: Quick editing with svg files using inkspace to generate braillebug.svg icon & background image for activity


• XML file : Edited the content for xml file with explaination in manual,description & other sections.


• Links :
  I checked braille codes from wikipedia : http://en.wikipedia.org/wiki/Braille
  I have pushed my code on github : https://github.com/srish/braille_alphabets-activity/
  


• Issues :
  1)When I click on the dots in braille cell area once I make their set property to "red", I am unable to get them back to original color on reclicking.
  2)How to disable the button and return focus to the dot.Trying out:self.c1.props.visibility = goocanvas.ITEM_INVISIBLE
  3)To prevent the overlapping of images in alphabet area.
  4)Probem with my git.gnome account.I am unable to push my code due to RSA verification failure.


• What I am planning to do next week !
  Complete my first activity & incorporate the similar implementations for numerals & symbols.
  To cover as much as possible work for second activity.
