how to include a Check in the Lwuit command?

Question

Hi I want to include a check (as in a tick mark) besides the command on the display screen.IS there any way I can implement it?

You can create the new class with implement the ListCellRenderer interface or extend with DefaultListCellRenderer class. Then implement all abstract methods and override getListCellRendererComponent method like this,

public Component getListCellRendererComponent(List list, Object value, 
                                             int index, boolean isSelected) {

        if (isSelected && list.hasFocus()) {
// do selected style that means selected command style
        } else {
// do unselected style that means unselected command style    
        }
return this;
    }

For your reference see this link.

Finally you need to pass this renderer class to setMenuRenderer method.

For single form means do like this,

Form form = new Form();
form.setMenuRenderer(new MenuRenderer()); // pass your created render class

For all form means do like this,

UIManager.getInstance().getLookAndFeel()
          .setMenuRenderer(new MenuRenderer()); // pass your created render class
