Question

I have a screen with two RadioButtonField objects. By default, the first RadioButtonField shows a rectangle around it to show its selected, and the rectangle moves if you change the selection to the other RadioButtonField or other buttons and textboxes on the page. What I would like to know is…is there a way to hide this border that shows the selection/border?

if you in 4.6 and higher, try to setBorder() without edges:

class Scr extends MainScreen {  
    EditField editField = new EditField("edit field", "text");
    RadioButtonGroup rbGroup = new RadioButtonGroup();
    RadioButtonField rbField = new RadioButtonField("First field");
    RadioButtonField rbField2 = new RadioButtonField("Second field");
    ButtonField buttonField = new ButtonField("button");
    Border invisibleBorder = 
        BorderFactory.createSimpleBorder(new XYEdges(0,0,0,0));     
    public Scr() {
        add(editField);
        rbGroup.add(rbField);
        rbGroup.add(rbField2);
        add(rbField);
        add(rbField2);      
        add(buttonField);       
        editField.setBorder(invisibleBorder);
        rbField.setBorder(invisibleBorder);
        rbField2.setBorder(invisibleBorder);        
        buttonField.setBorder(invisibleBorder);             
    }
}

If you in 4.5 and lower, try to override drawFocus() and leave it empty:

class Scr extends MainScreen {
    EditField editField = new EditField("edit field", "text") {
        protected void drawFocus(Graphics graphics, boolean on) {
        }
    };
    RadioButtonGroup rbGroup = new RadioButtonGroup();
    RadioButtonField rbField = new RadioButtonField("First field") {
        protected void drawFocus(Graphics graphics, boolean on) {
        }
    };
    RadioButtonField rbField2 = new RadioButtonField("Second field") {
        protected void drawFocus(Graphics graphics, boolean on) {
        }
    };
    ButtonField buttonField = new ButtonField("button") {
        protected void drawFocus(Graphics graphics, boolean on) {
        }
    };

    public Scr() {
        add(editField);
        rbGroup.add(rbField);
        rbGroup.add(rbField2);
        add(rbField);
        add(rbField2);
        add(buttonField);
    }
}
