~~Title: Replacing Standard About Dialog~~

It's not tricky to replace the standard About dialog. Simply override the method

<file java>
@Override
public void doAbout(UIActionEvent pEvent) throws Throwable
{
    openContent(this, null, true, "com.sibvisions.apps.demo.DemoAbout", this);
}
</file>
in your custom application class. If you don't have a custom application class, simply create one by extending ProjX. The class should be located in the **src.client** folder. Be sure that you change your launcher files and the deployment descriptor (replace ProjX with your application class).

Your //DemoAbout// class should extend the ProjX' //About// class:

<file java DemoAbout.java>
public class DemoAbout extends About
{
    public DemoAbout(IWorkScreenApplication pApplication)
    {
        super(pApplication);
    }

    @Override
    protected void init()
    {
        super.init();

        IWorkScreenApplication app = getApplication();

        UIPanel panLicense = new UIPanel();
        ...                

        getTabsetPanel().add(panLicense, "License");

        UIButton butClear = new UIButton("Clear");
        butClear.setBorderOnMouseEntered(true);
        butClear.eventAction().addListener(this, "doClear");
        butClear.setFocusable(false);

        UIPanel panButtons = getButtonPanel();
                
        UIFormLayout flButtons = (UIFormLayout)panButtons.getLayout();
                
        panButtons.add(butChangeLicense, flButtons.getLeftAlignedConstraints(0, 0));
    }

    public void doClear()
    {
        //Custom code
    }
}
</file>

Our custom About dialog adds a new Tabset and a Clear Button in the bottom area.
