如何使标签在 GridPane 中完全可见？

  • 772

我有一个 GridPane，其中标签和文本字段交替显示（标签、文本字段、标签、文本字段）。标签的宽度可以是任意的，并且永远不会提前知道。我需要确保标签始终完全可见，这意味着它们不会被截断（...），并且只有 TextField 会缩小。这是我的代码：

public class NewMain extends Application {

    @Override
    public void start(Stage stage) {
        GridPane gridPane = new GridPane();
        gridPane.setHgap(10);
        gridPane.setVgap(10);
        gridPane.setPadding(new Insets(10));

        Label label1 = new Label("Label AAAAA BBBBB:");
        label1.setMinWidth(Region.USE_COMPUTED_SIZE);
        TextField textField1 = new TextField();
        textField1.setMinWidth(10);
        GridPane.setHgrow(textField1, Priority.ALWAYS);
        Label label2 = new Label("Label CCCCCC DDDDDD:");
        label2.setMinWidth(Region.USE_COMPUTED_SIZE);
        TextField textField2 = new TextField();
        GridPane.setHgrow(textField2, Priority.ALWAYS);
        textField2.setMinWidth(10);

        gridPane.add(label1, 0, 0);
        gridPane.add(textField1, 1, 0);
        gridPane.add(label2, 2, 0);
        gridPane.add(textField2, 3, 0);

        ColumnConstraints labelColumn = new ColumnConstraints();
        labelColumn.setHgrow(Priority.NEVER);

        ColumnConstraints textFieldColumn = new ColumnConstraints();
        textFieldColumn.setMinWidth(50);
        textFieldColumn.setHgrow(Priority.ALWAYS);

        gridPane.getColumnConstraints().addAll(
            labelColumn, textFieldColumn,
            labelColumn, textFieldColumn
        );

        Scene scene = new Scene(gridPane, 600, 100);
        stage.setTitle("GridPane Single Row Test");
        stage.setScene(scene);
        stage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

结果如下：

有人能告诉我该怎么做吗？

    标签的计算尺寸考虑到了它可以被截断的事实。首选尺寸将为您提供它“想要”的尺寸，并且它不希望被截断。只需将最小宽度设置为Region.USE_PREF_SIZE：

    public class NewMain extends Application {

    @Override
    public void start(Stage stage) {
        GridPane gridPane = new GridPane();
        gridPane.setHgap(10);
        gridPane.setVgap(10);
        gridPane.setPadding(new Insets(10));

        Label label1 = new Label("Label AAAAA BBBBB:");
        label1.setMinWidth(Region.USE_PREF_SIZE);
        TextField textField1 = new TextField();
        textField1.setMinWidth(10);
        Label label2 = new Label("Label CCCCCC DDDDDD:");
        label2.setMinWidth(Region.USE_PREF_SIZE);
        TextField textField2 = new TextField();
        textField2.setMinWidth(10);

        gridPane.add(label1, 0, 0);
        gridPane.add(textField1, 1, 0);
        gridPane.add(label2, 2, 0);
        gridPane.add(textField2, 3, 0);


        Scene scene = new Scene(gridPane, 600, 100);
        stage.setTitle("GridPane Single Row Test");
        stage.setScene(scene);
        stage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}
