This example retrieves all the tabs in a tabbed pane:

    // To create a tabbed pane, see e828 创建JTabbedPane

    // Get number of tabs

    int count = pane.getTabCount();

    // Get the properties of each tab

    for (int i=0; i<count; i++) {

        // Get label

        String label = pane.getTitleAt(i);

        // Get icon

        Icon icon = pane.getIconAt(i);

        // Get tool tip

        String tooltip = pane.getToolTipTextAt(i);

        // Is enabled?

        boolean enabled = pane.isEnabledAt(i);

        // Get mnemonic

        int keycode = pane.getMnemonicAt(i);

        // Get component associated with tab

        Component comp = pane.getComponentAt(i);

    }

Most of the methods that allow the properties of a tab to be changed require the index of the tab. The index of a tab can change as tabs are added, removed, or moved. Here are three ways to retrieve the index of a tab when needed.

    // Get the index of the first tab that matches a label

    String label = "Tab Label";

    int index = pane.indexOfTab(label);

    // Get the index of the first tab that matches an icon; the supplied

    // icon must be the same instance that was used to create the tab

    index = pane.indexOfTab(icon);

    // Get the index of the tab by matching the child component; the supplied

    // component must be the same instance that was used to create the tab

    index = pane.indexOfComponent(component);

    if (index < 0) {

        // The tab could not be found

    }
