javafx

Question

At normal

At full screen

我想让第二个场景（粉红色）适合 anchorPane 的确切大小（绿色区域）

代码如下

FormOne.fxml

 <?xml version="1.0" encoding="UTF-8"?>

<?import java.net.URL?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane id="AnchorPane" prefHeight="500.0" prefWidth="600.0" styleClass="mainFxmlClass" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="javafx.test.controller.FormeOneController">
    <stylesheets>
        <URL value="@/javafx/test/style/formeone.css" />
    </stylesheets>
   <children>
      <AnchorPane prefHeight="500.0" prefWidth="130.0" style="-fx-background-color: #660066;" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.topAnchor="0.0">
         <children>
            <Button fx:id="btnPanel1" layoutX="31.0" layoutY="31.0" mnemonicParsing="false" onAction="#btnPanel1Action" text="Panel 1" />
            <Button fx:id="btnPanel2" layoutX="31.0" layoutY="92.0" mnemonicParsing="false" onAction="#btnPanel2Action" text="Panle 2" />
            <Button fx:id="btnPanel3" layoutX="31.0" layoutY="155.0" mnemonicParsing="false" onAction="#btnPanel3Action" text="Panle 3" />
         </children>
      </AnchorPane>
      <AnchorPane fx:id="showPane" layoutX="128.0" prefHeight="500.0" prefWidth="472.0" style="-fx-background-color: #00ff00;" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="128.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
   </children>
</AnchorPane>

PanelOne.fxml

 <?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.AnchorPane?>


<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" style="-fx-background-color: #ff00ff;" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" />

    @FXML

    /**

     */
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }    

    @FXML
    private void btnPanel1Action(ActionEvent event) throws IOException {
        AnchorPane pnlOne = FXMLLoader.load(this.getClass().getResource("/javafx/test/ui/PanelOne.fxml"));
        showPane.getChildren().setAll(pnlOne);
    }

}

Answer 1

您可以简单地使用 AnchorPane 的锚点来完成此操作。

@FXML
private void btnPanel1Action(ActionEvent event) throws IOException {
    AnchorPane pnlOne = FXMLLoader.load(this.getClass().getResource("/javafx/test/ui/PanelOne.fxml"));
    AnchorPane.setLeftAnchor(pnlOne, 0.0);
    AnchorPane.setTopAnchor(pnlOne, 0.0);
    AnchorPane.setRightAnchor(pnlOne, 0.0);
    AnchorPane.setBottomAnchor(pnlOne, 0.0);
    showPane.getChildren().setAll(pnlOne);
}

这里发生了什么？每个节点都有一些内部属性。使用上面的行，您可以设置属性当 pnlOne 是 AnchorPane.

的子项时应如何布局

javafx - 同一阶段的多个场景

javafx - multiple scenes in same stage
