Hi Walter, thanks for your question.

I think the method

AbstractTabBox.setSelectedTab(IGroupBox)

is what you are looking for.

I created a TabBox with 3 Tabs:

TabBox
 - Tab1Box
 - Tab2Box
 - Tab3Box

Then I created a Button with an execClickAction and the following implementation

    public class SwitchButton extends AbstractButton {
      int i = 0;

      @Override
      protected void execClickAction() throws ProcessingException {
        TabBox tabBox = getTabBox();
        IGroupBox selectedTab = tabBox.getSelectedTab(); //this one is selected
        if (i % 3 == 0) {
          tabBox.setSelectedTab(getTab1Box());
        }
        else if (i % 3 == 1) {
          tabBox.setSelectedTab(getTab2Box());
        }
        else if (i % 3 == 2 {
          tabBox.setSelectedTab(getTab3Box());
        }
        i++;
      }
    }

What this method does is, it switches to the next Tab if one clicks on the button. I have a counter (i) which will be increased by one if you click the button. The modulo operation (%) makes sure to get values between 0 and 2. If i == 0, show first tab, if i == 1 show second tab and if i == 2 show last tab.

Hope this helps.
Greetings,
Matthias
