问题
I am new to JavaFx and I am trying to create a tableview and fxml is created using scene builder. If I run the program, the table is not getting the values. I found that this question is somehow matching with my requirement (javaFX 2.2 - Not able to populate table from Controller), but my code is matching with that too. But still I am not able to get the values in the table.
I have referenced the following video : http://www.youtube.com/watch?v=HiZ-glk9_LE
My code is as follows,
MainView.java
/*

package controller;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;
public class MainView extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
try {
AnchorPane page = FXMLLoader.load(MainView.class.getResource("MainView.fxml"));
Scene scene = new Scene(page);
primaryStage.setScene(scene);
primaryStage.setTitle("Sample Window");
primaryStage.setResizable(false);
primaryStage.show();
} catch (Exception e) {
}
}
}

Thanks in advance.
回答1:
In a Table.java change all getters and setters names,
change getr* to getR*
change setr* to setR*
回答2:
Thanks to @Uluk Biy. Whatever he mentioned, that needs to be changed and I found that I missed the <cellValueFactory> and <PropertyValueFactory> tags under the <TableColumn> tag for each columns in the FXML file which is as follows,
<TableColumn minWidth="20.0" prefWidth="40.0" text="ID" fx:id="tID" >
<cellValueFactory>
<PropertyValueFactory property="tID" />
</cellValueFactory>
</TableColumn>
Similar to this, all columns need to be updated like this.
After this change, the code is working fine. I am able to add the values into the row. :)
