如您所见,我的文本受label
s约束。如何使label
调整大小以完全适合文本,并相应地调整VBox
和GridPane
的大小。我只想垂直调整大小。
我的FXML:
<VBox fx:id="body"
alignment="TOP_CENTER"
prefHeight="150"
GridPane.vgrow="SOMETIMES"
prefWidth="300"
GridPane.columnIndex="0"
GridPane.rowIndex="1" spacing="5">
<Label alignment="CENTER" textAlignment="JUSTIFY" fx:id="word" maxWidth="268"/>
<Pane prefHeight="10" VBox.vgrow="NEVER"/>
<Label alignment="CENTER" textAlignment="JUSTIFY" wrapText="true" fx:id="meaning" maxWidth="268" />
<Label alignment="CENTER" textAlignment="JUSTIFY" wrapText="true" fx:id="sentence" maxWidth="268" />
</VBox>
此VBox
位于GridPane
:
<GridPane fx:id="base"
alignment="CENTER"
prefHeight="210.0"
maxWidth="310.0"
stylesheets="@style.css"
vgap="0" xmlns="http://javafx.com/javafx/8"
xmlns:fx="http://javafx.com/fxml/1"
fx:controller="sample.Controller">
...
@James_D要求的最小,完整且可验证的示例
主类:
public class Main extends Application {
private Stage stage;
private StackPane stackPane;
@Override
public void start(Stage primaryStage) throws Exception{
stage = primaryStage;
FXMLLoader loader = new FXMLLoader(getClass().getResource("sample.fxml"));
Parent root = (Parent) loader.load();
stackPane = new StackPane(root);
Scene scene = new Scene(stackPane);
scene.setFill(Color.WHITE);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
控制器类:
public class Controller implements Initializable{
@FXML private Label label1;
@FXML private Button changeLabel;
private StringProperty labelString = new SimpleStringProperty();
@Override
public void initialize(URL location, ResourceBundle resources) {
labelString.setValue("aasdasd sad asdasd asdasda");
label1.textProperty().bind(labelString);
}
@FXML
public void clicked(MouseEvent e){
labelString.setValue("asdsadasd asdasdasd sfdgsfwoef fgtrhfgbdrgdf dfgdfivbjkfd gdfgidfjvdf gdfgjldkvbdf gjdilgjdfv dfgojdflkgdf ");
}
}
sample.fxml:
<GridPane fx:controller="sample.Controller"
xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10" maxHeight="Infinity">
<children>
<VBox fx:id="body"
alignment="CENTER"
maxHeight="Infinity"
GridPane.vgrow="SOMETIMES"
prefWidth="300"
GridPane.columnIndex="0"
GridPane.rowIndex="1" spacing="5">
<Label alignment="CENTER" VBox.vgrow="ALWAYS" wrapText="true" textAlignment="CENTER" fx:id="label1" maxWidth="268"/>
<Button fx:id="changeLabel" text="Change" minWidth="50" onMouseClicked="#clicked" maxWidth="Infinity" />
</VBox>
</children>
期望: 当我按“更改”时按钮,一切都应调整大小,以便为文本显示提供足够的空间。
问题: 当我按“更改”时按钮,UI保持不变,不显示全文。
答案 0 :(得分:3)
假设您希望文本换行,标签需要能够垂直增长。添加属性
maxHeight="Infinity"
到每个标签。您还使用VBox
约束prefHeight="150"
的总体高度;删除该属性,让VBox
找出自己的高度。同样,您可能希望从prefHeight
删除GridPane
属性。
