Replacing standard About dialog

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

@Override
public void doAbout(UIActionEvent pEvent) throws Throwable
{
    openContent(this, null, true, "com.sibvisions.apps.demo.DemoAbout", this);
}

Your DemoAbout class should extend the standard About class:

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
    }
}

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