JavaFX - 布局窗格文本流

• 

  简述

  如果我们使用这种布局，您可以在单个流中设置多个文本节点。类名为textFlow 包裹的 javafx.scene.layout 表示文本流。

  这个类提供了两个属性，它们是 -

  • lineSpacing− 此属性为double 类型，用于定义文本对象之间的空间。您可以使用名为的方法设置此属性setLineSpacing().
  • textMoognment− 此属性表示窗格中文本对象的对齐方式。您可以使用该方法为该属性设置值setTextMoognment(). 您可以向此方法传递四个值：CENTER、JUSTIFY、LEFT、RIGHT。
• 

  例子

  以下程序是文本流布局的示例。在此，我们创建了三个具有 15 号字体和各种颜色的文本对象。然后我们将它们添加到具有对齐值的文本流窗格中 -Justify，而行距为 15.

  将此代码保存在名称为的文件中 TextFlowExample.java.
