I'm not aware of anything in the API that will allow you to write right to left like that. It's possible to achieve this by creating a custom class that extends field. If you need more direction with this, I would search for "create custom field" in the forum.

hi superdirt,

Thanks for the reply

Here im posting the code where in the text gets printed from the right but it is scrolling to the left and it is not changing the position of the cursor,im setting the position of the cursor still no change

class CustomEditField extends Manager
{
private int _fieldHeight = 0;
private int _fieldWidth = 0;
private long _alignment;
private Font _font = Font.getDefault();
private AlignableEditField _editField;


public CustomEditField(String initialValue, int maxNumChars, long style)
{
super(NO_VERTICAL_SCROLL | NO_VERTICAL_SCROLLBAR);
_alignment = (style & BasicEditField.FIELD_HALIGN_MASK & BasicEditField.FIELD_TRAILING);

_editField = new AlignableEditField(null, initialValue, maxNumChars, style)
{
protected void onFocus(int direction)
{
setCursorPosition(0);
};
};
add(_editField);
}

protected void paint(Graphics g) {
super.paint(g);
}

public int getPreferredWidth() {
return _fieldWidth;
}

public int getPreferredHeight() {
return _font.getHeight();
}

public String getText() {
return _editField.getText();
}

public void setFont(Font value) {
_font = value;
_editField.setFont(_font);
}

protected void sublayout(int width, int height) {
if (_fieldWidth == 0) {
_fieldHeight = height;
_fieldWidth = width;
setExtent(width, _fieldHeight);
}

int textWidth = _editField.getPreferredWidth();

layoutChild(_editField, textWidth, _fieldHeight);

if (_alignment == FIELD_RIGHT)
{
setPositionChild(_editField, getPreferredWidth() - textWidth-10, 0);
}
else if (_alignment == FIELD_HCENTER)
{
setPositionChild(_editField,
(getPreferredWidth() - textWidth) / 2, 0);
}
else
{
// FIELD_LEFT
setPositionChild(_editField, 0, 0);
}
}

private void layoutEditField() {
sublayout(_fieldWidth, _fieldHeight);
}

private class AlignableEditField extends BasicEditField
{
public AlignableEditField(String label, String initialValue,int maxNumChars, long style)
{
super(label, initialValue, maxNumChars, style);
}

public int getPreferredWidth()
{
return Math.max(_font.getAdvance(getText()), _font.getAdvance('0'))+ _font.getAdvance(' ');
}

protected boolean keyChar(char key, int status, int time)
{
boolean result = super.keyChar(key, status, time);
layoutEditField();
return result;
}
/* protected void onFocus(int direction)
{
setCursorPosition(0);
super.onFocus(direction);
}*/


}

}
}


iam unable to understand what are the changes that need to b done.

Do you want like Arabic style or if any person enter data the we have to show it in reverse order; 

[cyndrilla]

when we enter the data as well as when we display the data both should be in arabic style.


Thanks

Set the style of Editfield as Field.FIELD_LEADING | DrawStyle.LEADING  . It will automatically display the arabic and hebrew language in right to left mode.
