UI Programming

You can use normal MIDP programming when using J2ME Polish, as the J2ME Polish UI is compatible with the MIDP 2.0 standard. On MIDP devices you can also mix MIDP UI and J2ME Polish UI classes by using classes such as de.enough.polish.midp.ui.TextBox.
Please also check out the UI Basics documentation as well as the Visual Guide.
Use #style preprocessing directives for binding UI components to CSS styles defined in resources/polish.css:

package de.enough.polish.sample.browser;

import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

import de.enough.polish.browser.html.HtmlBrowser;

public class BrowserMidlet 
	extends MIDlet
	implements CommandListener
{
	private Command cmdBack = new Command("Back", Command.BACK, 9);
	private Command cmdExit = new Command("Exit", Command.EXIT, 10 );
	private Form browserScreen;
	private HtmlBrowser htmlBrowser;

     protected void startApp() throws MIDletStateChangeException{
          Display display = Display.getDisplay( this );
          if (this.browserScreen == null) {
	          //#style browserScreen
	          Form form = new Form("HTML Browser");
	          //#style browser
	          this.htmlBrowser = new HtmlBrowser();
	          // you can add a gzip resource handler for reading gzipped resources:
	          //this.htmlBrowser.addProtocolHandler( new GZipResourceProtocolHandler() );
	          new ChartTagHandler( this.htmlBrowser.getTagHandler("div")).register(this.htmlBrowser);
	          form.append(this.htmlBrowser);
	          this.htmlBrowser.go( "resource://index.html");
	          this.htmlBrowser.setBackCommand( this.cmdBack );
	          form.addCommand( this.cmdExit );
	          form.setCommandListener( this );
	          this.browserScreen = form;
          }
          display.setCurrent( this.browserScreen );
     }

     protected void pauseApp(){
          // ignore
     }

     protected void destroyApp(boolean unconditional) throws MIDletStateChangeException{
          // just exit
     }

	public void commandAction(Command cmd, Displayable disp) {
	    //#debug
		System.out.println("BrowserMidlet.commandAction for cmd=" + cmd.getLabel() );
		if (cmd == this.cmdBack) {
			this.htmlBrowser.goBack();
		} else if (cmd == this.cmdExit) {
			//destroyApp( true );
			notifyDestroyed();
		}
	}

}

Note that J2ME Polish includes many sample applications which you should look at.
