Is there a function to open an 'xwt string'?
In the following example I've to create a temporary file to be able to open the 'xwt string'.

package test;

import java.io.*;
import java.net.URL;
import org.eclipse.e4.xwt.XWT;

public class Test {

	public static void main(String[] args) throws IOException {
		String xwtstr = "<Composite xmlns=\"http://www.eclipse.org/xwt/presentation\"  xmlns:x=\"http://www.eclipse.org/xwt\"><Composite.layout> <GridLayout numColumns=\"1\"/> </Composite.layout> <Text text=\"test text\" x:style=\"SWT.NONE\"></Text></Composite>";
		File xwtTemp = File.createTempFile("Test", ".xwt"); 
		xwtTemp.deleteOnExit();
		BufferedWriter out = new BufferedWriter(new FileWriter(xwtTemp));
		out.write(xwtstr);
		out.close(); 
		@SuppressWarnings("deprecation")
		URL url = xwtTemp.toURL();
		try {
			XWT.open(url);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

You can create directly InputStream with the content in string and then call
XWT.open(InputStream input, URL referenceLocation). This feature is used by
XWT Visual Design Editor to display in memory code.

XWT.open(InputStream input, URL referenceLocation) ?

I see only XWT.load(InputStream input, URL referenceLocation)

Can I do this?
Control root = XWT.load(inputStream, xwturl );
Shell shell = root.getShell();
shell.open();
