java - 在 JavaFX TableView 中设置行高

Question

如何在 JavaFX 表格 View 中设置行高？我试图通过使用 css 来增加它，但这没有用:

.table-row{
    line-height: 50px;
}

还有什么办法可以解决吗？

Answer 1

你可以使用

.table-row-cell {
    -fx-cell-size: 50px;
}

.table-row-cell 是分配给表行的类，如 capian.css 中所述，可从 jfxrt.jar (com/sun/javafx/scene/control/skin/caspian/caspian.css):

Each row in the table is a table-row-cell. Inside a table-row-cell is any number of table-cell.

而 -fx-cell-size，在本例中，是行高(实际上是每个单元格的高度)，如 Oracle's JavaFX CSS Reference Guide 确认的那样

-fx-cell-size: The cell size. For vertical ListView or a TreeView or TableView this is the height, for a horizontal ListView this is the width.

我在下面的例子中尝试了上面的解决方案:

PetsTable:(注意使用scene.getStylesheets().add("styles/styles.css");，定义要使用的css文件)

import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.stage.Stage;

public class PetsTable extends Application {

    @SuppressWarnings({ "rawtypes", "unchecked" })
    @Override
    public void start(Stage stage) {
        Scene scene = new Scene(new Group());
        stage.setTitle("Pets");
        stage.setWidth(200);
        stage.setHeight(200);

        ObservableList<Pet> data = FXCollections.observableArrayList(new Pet("Kitty", "Susan"), 
                new Pet("Ploft", "Jackob"));
        TableView<Pet> table = new TableView<Pet>();

        TableColumn name = new TableColumn("Name");
        name.setMinWidth(100);
        name.setCellValueFactory(new PropertyValueFactory<Pet, String>("name"));

        TableColumn owner = new TableColumn("Owner");
        owner.setMinWidth(100);
        owner.setCellValueFactory(new PropertyValueFactory<Pet, String>("owner"));

        table.setItems(data);
        table.getColumns().addAll(name, owner);

        ((Group) scene.getRoot()).getChildren().addAll(table);

        /**********************************************/
        /********* Setting the css style file *******/
        /**********************************************/
        scene.getStylesheets().add("styles/styles.css");

        stage.setScene(scene);
        stage.show();
    }

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

    public static class Pet {

        private final SimpleStringProperty name;
        private final SimpleStringProperty owner;

        private Pet(String name, String owner) {
            this.name = new SimpleStringProperty(name);
            this.owner = new SimpleStringProperty(owner);
        }

        public String getName() {
            return name.get();
        }

        public String getOwner() {
            return owner.get();
        }
    }
}

样式.css:

.table-row-cell {
    -fx-cell-size: 50px;
}
