Books version 1.2

This week I shared version 1.2 of Books, so I updated the blog entry listing all features and related JSRs.

Alphabet: my third study case

With this application you can help your children learn the alphabet. Three letters at a time. When the child correctly presses the key for each letter three other letters are presented. There is a counter to stimulate the child to achieve higher scores. You can change letter colors based on the handset theme, but the application also have predefined colors.

The application is available for downloa here.

Adding a simple progress bar

A progress bar is a visual representation of a Real Number between zero and one or a percentage between 0% and 100%.

Below is a method for drawing a simple progress bar:

/**
 * @param g Graphics
 * @param x
 * @param y
 * @param w width
 * @param h height
 * @param p part between zero and total
 * @param t total
 */
void fillProgressBar (Graphics g, int x, int y, int w, int h, int p, int t) {
  g.drawRect(x, y, w, h);
  // p will receive the pixel width of the proportion: part / total
  p = (p * w) / t;
  g.fillRect(x, y, p, h);
}
