我有一个 .fxml 文件,其中有一些空的矩形,磨碎内
<AnchorPane id="AnchorPane" prefHeight="700.0" prefWidth="650.0" styleClass="fondo2" stylesheets="@tablerolote.css" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="juegoloto.CartonController">
<children>
<GridPane gridLinesVisible="true" layoutX="11.0" layoutY="44.0" prefHeight="614.0" prefWidth="474.0" styleClass="fondo">
<columnConstraints>
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
</columnConstraints>
<rowConstraints>
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
</rowConstraints>
<children>
<ImageView id="1" fitHeight="127.0" fitWidth="93.0" pickOnBounds="true" preserveRatio="true" />
<ImageView id="2" fitHeight="127.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="1" />
<ImageView id="3" fitHeight="126.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="2" />
<ImageView id="4" fitHeight="127.0" fitWidth="97.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="3" />
</children>
</GridPane>
</children>
</AnchorPane>
它是使用netbeans(拖放界面)自动创建的,我如何发送图像并在 ImageView id="2"/ImageView id="3"
等中显示,从.java 文件
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("Carton.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
我也有一个controller.java文件,但我不知道如何处理它
public class CartonController implements Initializable {
@FXML
private Label label;
@FXML
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
最佳答案
您应该在 Controller 类中执行此操作。 FXML reference 中完整描述了如何使用 Controller 。 ,但简而言之:
将 fx:id
放在 ImageView
上(您可以在 SceneBuilder 中执行此操作):
<AnchorPane id="AnchorPane" prefHeight="700.0" prefWidth="650.0" styleClass="fondo2" stylesheets="@tablerolote.css" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="juegoloto.CartonController">
<children>
<GridPane gridLinesVisible="true" layoutX="11.0" layoutY="44.0" prefHeight="614.0" prefWidth="474.0" styleClass="fondo">
<columnConstraints>
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
</columnConstraints>
<rowConstraints>
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
</rowConstraints>
<children>
<ImageView id="1" fx:id="imageView1" fitHeight="127.0" fitWidth="93.0" pickOnBounds="true" preserveRatio="true" />
<ImageView id="2" fx:id="imageView2" fitHeight="127.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="1" />
<ImageView id="3" fx:id="imageView3" fitHeight="126.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="2" />
<ImageView id="4" fx:id="imageView4" fitHeight="127.0" fitWidth="97.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="3" />
</children>
</GridPane>
</children>
</AnchorPane>
然后将它们注入(inject)到您的 Controller 中,您可以根据需要访问它们:
public class CartonController implements Initializable {
@FXML
private ImageView imageView1 ;
@FXML
private ImageView imageView2 ;
@FXML
private ImageView imageView3 ;
@FXML
private ImageView imageView4 ;
@Override
public void initialize(URL url, ResourceBundle rb) {
imageView1.setImage(new Image(...));
// etc...
}
}
