JavaFX8选项卡窗格'；s标签不切换

下面是我用TabPane为GridPane编写的代码

选项卡窗格中有两个选项卡

当我在SceneBuilder上单击预览时，单击选项卡头部时，选项卡不会切换

根据您所需的大小更改此处选项卡窗格。

当您将鼠标事件设置为透明时，它在鼠标单击时不会执行任何操作：

mousetranspane=“true”

我猜这是偶然的，但当您将属性设置为true时：

如果为true，则此节点（及其所有子节点）完全为空 对鼠标事件透明。选择鼠标事件的目标时， mouseTransparent设置为true的节点及其子树将不会 考虑到

从您的FXML中删除提到的部分，您的预览将非常有效

在SceneBuilder中，在选项卡窗格的属性选项卡上：
