JavaFX TabPane: How to set the selected tab

Question

I have a Java Desktop Application with JavaFX 2 in it and in my FX I've got a TabPane. I want to set the default tab. In other words I want to set a tab as selected. I found that there are multiple ways to find out which tab is selected and I found setSelectionModel() but I can't figure out how to use it.

TabPane tabPane = new TabPane();

Tab tab0 = new Tab("blue");
tab.setContent(new Rectangle(200,200, Color.BLUE));

Tab tab1 = new Tab("green");
tab.setContent(new Rectangle(200,200, Color.GREEN));

tabPane.getTabs().addAll(tab0, tab1);

Answer 1

The SelectionModelis the right approach. You can get the default from your TabPane or assign your own implementation by using setSelectionModel(...). The default model should be good enough for the beginning.

SingleSelectionModel<Tab> selectionModel = tabPane.getSelectionModel();

Once you stored it in some local variable, you have different options to select a tab.

selectionModel.select(tab); //select by object
selectionModel.select(1); //select by index starting with 0
selectionModel.clearSelection(); //clear your selection

If you try to select a non existing tab, nothing will happen.
