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 SelectionModel is 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.

Answer 2

为简化上述方法：

myTabPane.getSelectionModel().select(myTab);

To continue with Menai's answer heres how to refocus the opened tab/TabPane.

SingleSelectionModel<Tab> selectionModel = TabPane.getSelectionModel();
if(!Tabpane.getTabs().contains(tabName)) {
   TabPane.getTabs().add(tabName);
   selectionModel.select(tabPane);
} else {
   selectionModel.select(tabPane); 
}

Answer 4

TabPane tabPane = new TabPane();

tabPane.getSelectionModel().select(); //Select Tab
tabPane.getSelectionModel().select(); //Select tab index
tabPane.getSelectionModel().selectLast();
tabPane.getSelectionModel().selectFirst();
tabPane.getSelectionModel().selectNext();
tabPane.getSelectionModel().selectPrevious();
tabPane.getSelectionModel().clearSelection(); //Select Tab
tabPane.getSelectionModel().clearSelection(); //Select tab index

If you work with statique tabs ,i mean your TabPane has statique number of tabs ,you can select your tab by this way :

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

        selectionModel.select(tabName);

If you work with dynamique tabs ,i mean your TabPane has dynamique number of tabs (add and remove tabs) ,you can select your tab by this way :

        if (!TabPane.getTabs().contains(tabName)) {

        TabPane.getTabs().add(tabName);

    }
    SingleSelectionModel<Tab> selectionModel = TabPane.getSelectionModel();

    selectionModel.select(tabPane);
