Including HTML and Javascript into canvas

Smart GWT Technical Q&A
1

Hi,

I was reading the developer guide and I saw that if you want to put custom HTML and JavaScript into a smartGWT app you should extend the Canvas class.
I was not able to find an example and I not sure how to proceed, of course I know how to extend a Java class, but how will I include my custom HTML/Javascript code into the nem Canvas class?

setContents(), or an override of getInnerHTML().

Thank you very much for your help, I’ll try that

Hi,
I tried the solution and unfortunately it didn’t work.
I would like to put the attached html into a canvas

public class GISBaseCavnas extends Canvas
{

   @Override
    public String getInnerHTML()
    {
        StringBuffer buff = new StringBuffer();
        buff.append(HTML ATTACHED);
        return buff.toString();
    }
}

As a result it should display a text and a map.
The output i got was only the text.
Is there some limitation on smartgwt that I’m not aware of?
Or am I doing something wrong?

Thank you very much
