TabLayoutPanel disable a Tab GWT

How can i disable a tab (i.e the user cannot open the tab when he clicks on it) in the TabLayoutPanel?I searched online but was not able to find a solution

Thanks

Solution

  • Use a BeforeSelectionHandler:

    TabLayoutPanel myPanel = new TabLayoutPanel();
// Add children...

myPanel.addBeforeSelectionHandler(new BeforeSelectionHandler<Integer>() {
  @Override
  public void onBeforeSelection(BeforeSelectionEvent<Integer> event) {
    // Simple if statement - your test for whether the tab should be disabled
    // will probably be more complicated
    if (event.getItem() == 1) {
      // Canceling the event prevents the tab from being selected.
      event.cancel();
    }
  }
});

    If you want to style the disabled tab differently than enabled tabs, you can use TabLayoutPanel#getTabWidget to get the tab widget and add a style name to it.
