TabLayoutPanel禁用Tab GWT

Question

如何在TabLayoutPanel中禁用选项卡(即用户无法在单击时打开选项卡)？我在线搜索但无法找到解决方案

谢谢

Answer 1

使用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();
    }
  }
});

如果要为禁用选项卡设置与启用选项卡不同的样式,则可以使用TabLayoutPanel#getTabWidget选项卡窗口小部件并为其添加样式名称.
