本文介绍了将TableView数据显示到另一个Window中，包含JavaFx中的TextField的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我制作了两个包含TextField的Fxml文件，另一个包含TableView。它有它的Controller类。我想在执行鼠标单击操作事件时将TableView中的数据显示到TextField。但我们没有得到结果它显示了很多错误，如：

流程已完成退出代码0
第一个Fxml文件名CompanyLayout.fxml包含TextFields和它的Controller类与CompanyController.java一样。它有按钮名称查找，当我点击该按钮时，打开包含TableView的CompanyTable.fxml。当我点击TableView的特定行时，该行的数据将显示在包含Textfields的CompanyLayout.fxml上。
查找CompanyController.java的按钮代码是这样的：
btnFind .setOnAction（new EventHandler< ActionEvent>（）{
@Override
public void handle（ActionEvent event）{
try {
Stage primaryStage = new Stage（）;
FXMLLoader loader = new FXMLLoader（）;
父root = loader.load（getClass（）。getClassLoader（）。getResource（Company \\CompanyTable.fxml））;
场景场景= new Scene（root）;
scene.getStylesheets（）。add（getClass（）。getClassLoader（）。getResource（Stylesheet \\style.css）。toExternalForm（））;
primaryStage .setTitle（Company Table）;
primaryStage.setScene（scene）;
primaryStage.show（）;
} catch（例外e）{
e .printStackTrace（）;
}
}
}）;
CompanyTableController.java的TableView代码是这样的：
CompanyTable.setOnMouseClicked（new EventHandler< MouseEvent>（）{
@Override
public void handle（MouseEvent event）{
Clicked（）;
}
}）;
private void Clicked（）
{
try
{
CompanyData categoryData = CompanyTable.getItems（）。get（CompanyTable.getSelectionModel（）。getSelectedIndex （））;
CategoryID.setText（categoryData.getCompanyID（））;
CategoryName.setText（categoryData.getCompanyName（））;
}
catch（例外e）
{
e.printStackTrace（）;
}
}
我希望你能理解这段代码，请帮忙我！
解决方案
我创建了一个演示你的问题的示例应用程序。
关键是将数据从一个控制器传递给另一个。您可以在此处找到相关信息。
以下是关键代码：
@FXML
private void handleButtonAction（ActionEvent event）{
try
{
FXMLLoader loader = new FXMLLoader（getClass（）。getResource（SearchPanel.fxml））;
父root = loader.load（）;
SearchPanelController searchPanelController = loader.getController（）; //访问Controller
阶段阶段=新阶段（）;
stage.setScene（new Scene（root））;
stage.showAndWait（）; //等待搜索控制器关闭。
客户tempCustomer = searchPanelController.getCustomer（）; //从搜索控制器获取所选客户。看看SearchPanelController吧！
//将所选客户设置为TextFields
tfFirstName.setText（tempCustomer.getFirstName（））;
tfLastName.setText（tempCustomer.getLastName（））;
tfEmail.setText（tempCustomer.getEmail（））;
} catch（IOException e）
{
e.printStackTrace（）;
}
}

The first Fxml file name CompanyLayout.fxml contains TextFields and it has its Controller class like CompanyController.java. It has Button name Find when i clicked on that button CompanyTable.fxml is opened which contain TableView. When i clicked on perticular row of TableView the data of that row will display on CompanyLayout.fxml which contains Textfields.
Find Button code for CompanyController.java is this:
btnFind.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
try {
Stage primaryStage = new Stage();
FXMLLoader loader = new FXMLLoader();
Parent root = loader.load(getClass().getClassLoader().getResource("Company\\CompanyTable.fxml"));
Scene scene=new Scene(root);
scene.getStylesheets().add(getClass().getClassLoader().getResource("Stylesheet\\style.css").toExternalForm());
primaryStage.setTitle("Company Table");
primaryStage.setScene(scene);
primaryStage.show();
} catch (Exception e) {
e.printStackTrace();
}
}
});
TableView Code for CompanyTableController.java is this:
CompanyTable.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
Clicked();
}
});
private void Clicked()
{
try
{
CompanyData categoryData=CompanyTable.getItems().get(CompanyTable.getSelectionModel().getSelectedIndex());
CategoryID.setText(categoryData.getCompanyID());
CategoryName.setText(categoryData.getCompanyName());
}
catch(Exception e)
{
e.printStackTrace();
}
}
I hope you will understand this code so, please help me!
解决方案
I created a sample app that demos your question.
The key is passing data from one Controller to another. You can find info here.
Here is the key code:
@FXML
private void handleButtonAction(ActionEvent event) {
try
{
FXMLLoader loader = new FXMLLoader(getClass().getResource("SearchPanel.fxml"));
Parent root = loader.load();
SearchPanelController searchPanelController = loader.getController();//Get access to the Controller
Stage stage = new Stage();
stage.setScene(new Scene(root));
stage.showAndWait();//Wait for the Search Controller to close.
Customer tempCustomer = searchPanelController.getCustomer();//Get the selected customer from the Search Controller. HAVE A LOOK AT THE SearchPanelController!
//Set the selected customer to the TextFields
tfFirstName.setText(tempCustomer.getFirstName());
tfLastName.setText(tempCustomer.getLastName());
tfEmail.setText(tempCustomer.getEmail());
} catch (IOException e)
{
e.printStackTrace();
}
}
