Overview

The extension of the clipping area paints CustomItem over MIDP 2.0 and MIDP 2.1 high-level API items on Form in Series 40.

Description

When the clipping area of the y coordinate is extended (for example, y=80), the CustomItem object is painted over MIDP 2.0 and MIDP 2.1 high-level API items on Form.

How to reproduce

For example, implement a MIDlet using two TextField items and one CustomItem item. Include them on the Form in the following top-down order: TextField, CustomItem, TextField.

To test this issue, paint the CustomItem and set the clipping area using the following code snippet:

Image im;

...

try {
  im = Image.createImage("/filename.png");
} catch (IOException ex) {
  ex.printStackTrace();
}
...
 
protected void paint( Graphics g, int width, int height ) {
g.setClip(0, 80, width, height);       
g.drawImage (im, 0, 80,Graphics.TOP| Graphics.LEFT);  
} 

Solution

This issue has been fixed starting from Series 40 5th Edition, Feature Pack 1.
