【中文标题】在 JavaFX 中隐藏表格【英文标题】：Hiding a table in JavaFX 【发布时间】：2017-05-20 11:24:33 【问题描述】：我在 JavaFX 中有一个这样声明的表：
@FXML private TableView tableEF;
我怎样才能，例如当我按下一个按钮或更改 ComboBox 中的值时，将其从 GUI 中完全隐藏，然后在我按下另一个按钮或再次更改 ComboBox 中的值后，使其再次可见？

Edit2：“JavaFX - setVisible 不“隐藏”元素”的问题不是一个解决方案，因为对他来说 setInvisible 有效，因为它使 vBox 不可见，只是不会在它的位置移动另一个。我也已经尝试过那里提出的解决方案，但没有任何效果。
我还注意到，当我更改 ComboBox 中的值时，表 Fisa (tableEF) 会自行隐藏。
【问题讨论】：
请发布您当前的代码 JavaFX - setVisible doesnt "hide" the element的可能重复 你想隐藏它并让它占用可用空间还是隐藏它并删除它当前占用的空间？ 我想在同一位置的表之间进行更改。所以当我隐藏一张桌子时，另一张桌子应该出现在它的位置。 【参考方案1】：private final BooleanProperty tableHidden;
public AllController()
this.tableHidden = new SimpleBooleanProperty(false);
this.tableEF.visibleProperty().bind(this.tableHiddenProperty());
this.tableEF.managedProperty().bind(this.tableHiddenProperty().not());
// ...
// Standard FX property setter/getter...
public void makeTableHidden()
this.setTableHidden(true);
// ...
当然，你可以选择没有属性，直接设置TableView的visibleProperty和managedProperty，不过我觉得这样更简洁（个人意见）。
编辑
这些是 JavaFX properties 的 getter/setter 的标准命名约定（参见示例 1）。
表格的可见性也是这种属性的一个例子；它的private 属性（你看不到）被称为visible，它的public 版本（你可以看到）是visibleProperty，它的getter/setter 分别是isVisible 和setVisible。
这是您需要拥有的额外代码（我假设您已经知道如何自己生成一个）。
public final BooleanProperty tableHiddenProperty()
return this.tableHidden;
public final boolean isTableHidden()
return this.tableHiddenProperty().get;
public final void setTableHidden(final boolean value)
this.tableHiddenProperty().set(value);
【讨论】：
tableHiddenProperty() 是一个单独的 void 函数还是我必须从某个地方导入它？ @Artyomska 更新。以上是关于在 JavaFX 中隐藏表格的主要内容，如果未能解决你的问题，请参考以下文章
