Re: Creating a new Custombutton by subclassing a Button

I don't get why extending Button and also declare a Button as a field.
Joseph is right: call click() but pay attention on what, this.click() calls the click on the CustomButton instance, btn.click() calls the click on the inner declared Button field. As I say, I don't get having two of them.

Anyway take a look at TextButton and CustomButtn in GWT. I believe they can be easily used to achieve an image+text button.
Probably the quicker way is defining a simple image+text SafeHtmlTemplate and pass it to the Button(SafeHtml) constructor.
Choose you poison :)

I have created one CustomButton which consists of once image and one

public class CustomButton extends Button implements ClickHandler{

        private Label conflbl;
        private Button btn;

        public CustomButton(String imgUrl, String btnText) {
                this.parentScreen = parentScreen;
                Image img = new Image();
                img.setUrl(imgUrl);
                img.setSize("20px", "20px");
                AbsolutePanel panel = new AbsoultePanel();
                panel.add(img, nleft + 110, ntop - 30);
                btn = new Button();
                btn.setSize("250px", "300px");
                conflbl = new Label(btnText);
                conflbl.setSize("130", "60");
                panel.add(btn, nleft, ntop);
                panel.add(conflbl, nleft + 60, ntop + 40);
                conflbl.addClickHandler(this);
                btn.addClickHandler(this);
        }
@Override
        public void onClick(ClickEvent event) {
                // Handle the label and the button click here.
                // Then raise a fresh Click handler. But How???
                this.Click() // This is not working

        }
}

I want to raise a click event once this button is clicked and
obviously in the OnClick() handler of the CustomButton should receive
Source as the CustomButton (Not as Button). This way our CustomButton
will work truly as a button. I tried calling this.Click() but it is
not raising the event.
