问题描述
限时送ChatGPT账号..我想更改所有列的文本的外观,即SimpleStringProperty
.我想更改字体样式、字体名称、字体大小等...在我创建的 TableView
I want to change how the all column's text looks like which is a SimpleStringProperty
. I want to change font style,font name, font size etc... Below my creation of TableView
TableView<User> statisticsTable = new TableView<>();
//statisticsTable.setPrefHeight(DefaultValues.TE);
TableColumn nameCol = new TableColumn("Name");
nameCol.setMinWidth(240);
nameCol.setCellValueFactory(
new PropertyValueFactory<User, String>("fullName"));
nameCol.setResizable(false);
TableColumn todayTicketsCol = new TableColumn("Today Assigned Tickets");
todayTicketsCol.setMinWidth(160);
todayTicketsCol.setCellValueFactory(
new PropertyValueFactory<User, Integer>("totalOnTechnicalStudies"));
todayTicketsCol.setResizable(false);
TableColumn totalTechnicalStudiesCol = new TableColumn("Total Technical Studies");
totalTechnicalStudiesCol.setMinWidth(160);
totalTechnicalStudiesCol.setCellValueFactory(
new PropertyValueFactory<User, Integer>("totalAssignedTicket"));
totalTechnicalStudiesCol.setResizable(false);
usersForStatistics = FXCollections.observableArrayList(usersList);
statisticsTable.getColumns().addAll(nameCol,todayTicketsCol,totalTechnicalStudiesCol);
statisticsTable.setItems(usersForStatistics);
推荐答案
这是一个示例应用程序,演示了如何执行此操作.
Here is a sample app that demonstrates how to do this.
这个例子在 setCellFactory
方法中使用了 setTextFill()
和 setFont()
.
This example uses setTextFill()
and setFont()
inside the setCellFactory
method.
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.stage.Stage;
import javafx.util.Callback;
public class Main extends Application {
private final TableView<Person> table = new TableView<>();
private final ObservableList<Person> data =
FXCollections.observableArrayList(new Person("A", "B"));
final HBox hb = new HBox();
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage stage) {
Scene scene = new Scene(new Group());
stage.setWidth(450);
stage.setHeight(550);
TableColumn firstNameCol = new TableColumn("First Name");
firstNameCol.setMinWidth(100);
firstNameCol.setCellValueFactory(
new PropertyValueFactory<>("firstName"));
//Newly added code
firstNameCol.setCellFactory(new Callback<TableColumn, TableCell>() {
@Override
public TableCell call(TableColumn param) {
return new TableCell<Person, String>()
{
@Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if(isEmpty())
{
setText("");
}
else
{
setTextFill(Color.RED);
setFont(Font.font ("Verdana", 20));
setText(item);
}
}
};
}
});
TableColumn lastNameCol = new TableColumn("Last Name");
lastNameCol.setMinWidth(100);
lastNameCol.setCellValueFactory(
new PropertyValueFactory<>("lastName"));
lastNameCol.setCellFactory(new Callback<TableColumn, TableCell>() {
@Override
public TableCell call(TableColumn param)
{
return new TableCell<Person, String>()
{
@Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if(isEmpty())
{
setText("");
}
else
{
setTextFill(Color.BLUE);
setFont(Font.font ("Verdana", 20));
setText(item);
}
}
};
}
});
table.setItems(data);
table.getColumns().addAll(firstNameCol, lastNameCol);
final Button addButton = new Button("Add");
addButton.setOnAction((ActionEvent e) -> {
data.add(new Person("Z","X"));
});
hb.getChildren().addAll(addButton);
hb.setSpacing(3);
final VBox vbox = new VBox();
vbox.setSpacing(5);
vbox.setPadding(new Insets(10, 0, 0, 10));
vbox.getChildren().addAll(table, hb);
((Group) scene.getRoot()).getChildren().addAll(vbox);
stage.setScene(scene);
stage.show();
}
public static class Person {
private final SimpleStringProperty firstName;
private final SimpleStringProperty lastName;
private Person(String fName, String lName) {
this.firstName = new SimpleStringProperty(fName);
this.lastName = new SimpleStringProperty(lName);
}
public String getFirstName() {
return firstName.get();
}
public void setFirstName(String fName) {
firstName.set(fName);
}
public String getLastName() {
return lastName.get();
}
public void setLastName(String fName) {
lastName.set(fName);
}
}
}
