Question

我正在使用javafx在eclipse中创建登录表单和注册表单...当应用程序运行时，它显示登录和注册表单的默认大小..两个表单都有不同的大小..如何更新它？

代码如下

Samplecontroller.java

 public void signin() {
            AnchorPane pane2;

            try {
                pane2 = FXMLLoader.load(getClass().getResource("Login.fxml"))       
                root.getChildren().setAll(pane2);

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

FXML

<AnchorPane prefHeight="435.0" prefWidth="655.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8">
   <children>
      <ImageView fitHeight="435.0" fitWidth="655.0" pickOnBounds="true" preserveRatio="true">
         <image>
            <Image url="@../image/reg1.jpeg" />
         </image>
      </ImageView>
      <Label layoutX="278.0" layoutY="72.0" prefHeight="22.0" prefWidth="212.0" text="Login" textFill="#f8f7f7">
         <font>
            <Font name="Arial Bold Italic" size="39.0" />
         </font>
      </Label>
      <Label layoutX="38.0" layoutY="229.0" text="Email id" textFill="#19f236">
         <font>
            <Font name="System Bold" size="28.0" />
         </font>
  </Label>
  <Label layoutX="38.0" layoutY="309.0" text="Login id" textFill="#19f236">
     <font>
        <Font name="System Bold" size="22.0" />
     </font>
  </Label>
  <TextField layoutX="204.0" layoutY="237.0" prefHeight="25.0" prefWidth="326.0" />
  <TextField layoutX="209.0" layoutY="313.0" prefHeight="25.0" prefWidth="326.0" />
  <Button layoutX="252.0" layoutY="374.0" mnemonicParsing="false" text="Login" />
  <Button layoutX="428.0" layoutY="374.0" mnemonicParsing="false" text="Cancel" />
  <Label layoutX="52.0" layoutY="357.0" textFill="#ee1111">
     <font>
        <Font size="28.0" />
     </font>
  </Label>

并在主要班级

public void start(Stage primaryStage) {
        try {
            AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
            Scene scene = new Scene(root,300,300);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

Answer 1

在主类中，您将场景宽度和高度设置为300，它将覆盖启动时在fxml文件中设置的高度和宽度。所以我建议你只设置根到场景

Scene scene = new Scene(root);

这将允许从fxml文件中获取高度和宽度

如何在javafx
