导读:我在 JavaFX中创建了一个带有单个子组件(按钮)的TitledPane,如下所示: ?import java.lang.*??import javafx.scene.control.*??import javafx.scene.layout.*?AnchorPane id=AnchorPane prefHeight=400.0 prefWidth=600.0

我在 JavaFX中创建了一个带有单个子组件(按钮)的TitledPane,如下所示: <?import java.lang.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
<children>
<TitledPane animated="false" layoutX="137.0" layoutY="60.0" prefHeight="400.0" prefWidth="600.0" text="untitled" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<content>
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0" >
<children >
<Button layoutX="193.1875" layoutY="133.5" mnemonicParsing="false" prefHeight="374.0" prefWidth="598.0" text="Button" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
</children>
</AnchorPane>
</content>
</TitledPane>
</children>
</AnchorPane>
如下所示.按钮周围有相当多的间距,我想将其减少到0或者可能是单个像素.我没有看到任何可以执行此操作的AnchorPane或TitledPane的属性.有这样的财产吗? 解决方法使用 Scenic View找出这样的问题.TitledPane内部的AnchorPane四面都有0.8em(10px)的填充.这在默认样式表modena.css中定义.您可以在FXML中重置它: <?import java.lang.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.geometry.Insets?>
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
<children>
<TitledPane animated="false" text="untitled" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<content>
<AnchorPane >
<padding>
<Insets top="0" right="0" left="0" bottom="0"/>
</padding>
<children >
<Button mnemonicParsing="false" text="Button" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
</children>
</AnchorPane>
</content>
</TitledPane>
</children>
</AnchorPane>
或者带有外部样式表 .titled-pane > * > * > AnchorPane {
-fx-padding: 0em ;
