我有一个带有 CONSTRAINED_RESIZE_POLICY 列调整大小策略的 TableView。当我手动调整窗口大小时效果很好,但是当我最大化它或从最大化状态恢复它时,列不会调整。

有没有办法在 TableView 上强制“刷新”,以便在这些情况下调整列的大小?

更新:重现问题的示例可编译代码

public class TableViewResizeTest extends Application {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage primaryStage) {

    primaryStage.setTitle("TableView resize demo");

    ObservableList<Room> roomsList = FXCollections.observableArrayList();

    final TableView rooms = new TableView();
    TableColumn icons = new TableColumn();
    TableColumn name  = new TableColumn("Name");
    TableColumn topic = new TableColumn("Topic");
    TableColumn users = new TableColumn("Users");

    rooms.getColumns().addAll(icons, name, topic, users);

    name.setCellValueFactory( new PropertyValueFactory<Room,String>("name"));
    topic.setCellValueFactory( new PropertyValueFactory<Room,String>("topic"));
    users.setCellValueFactory( new PropertyValueFactory<Room,String>("users"));
    icons.setCellValueFactory( new PropertyValueFactory<Room,String>("icons"));

    name.setMinWidth(50);
    name.setMaxWidth(450);
    topic.setMinWidth(10);
    users.setMinWidth(100);
    users.setMaxWidth(150);

    icons.setMaxWidth(35);
    icons.setMinWidth(35);
    // Room resize policy, this is almost perfect
    rooms.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

    for (int i = 1; i<50; i++) roomsList.add(new Room("Sample Room "+i));
    rooms.setItems(roomsList);
    BorderPane root = new BorderPane();
    root.setCenter(rooms);
    primaryStage.setScene(new Scene(root, 500, 460));
    primaryStage.show();

}

public class Room {

    public Room(String name) {

        this.name = new SimpleStringProperty(name);
        this.topic= new SimpleStringProperty("This is a sample description text");
        this.icon= new SimpleStringProperty("");
        nUsers = (int)(Math.random()*1000);
        this.users= new SimpleStringProperty(nUsers.toString());
    }    

    Integer nUsers;

    private SimpleStringProperty name;
    private SimpleStringProperty topic;
    private SimpleStringProperty users;
    private SimpleStringProperty icon;


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

    public void setName(String name) {
        this.name.set(name);
    }

    public String getTopic() {
        return topic.get();
    }

    public void setTopic(String topic) {
        this.topic.set(topic);

    }

    public String getUsers() {
        return nUsers.toString();
    }

    public void setUsers(String users) {
        this.users.set(users);
    }


    public String getIcon() {
        return icon.get();
    }

    public void setIcon(String icon) {
        this.icon.set(icon);
    }
}   

}

根据调整大小政策,最后一列“用户”必须始终可见,如果您手动调整表单大小,它可以正常工作。但是,如果您尝试最大化和恢复几次,您会看到它脱离了视图,直到您手动调整窗口大小。

我想你想用最大和最小宽度边界限制名称、用户和图标列,而主题列占用其余的可用空间。作为一种解决方法,我建议将主题列放在列的末尾,即rooms.getColumns().addAll(icons, name, users, topic);.
