Continue your JavaFX Components learning via this tutorial.
Example 1: Filechooser
Let us look at the code
Step 1: Create Project
- Open your favorite Java IDE.
- In the menu go to
File --> Create New Project
.
Step 2: Dependencies
No dependencies are needed for this project.
Step 3: Write Code
Our code will comprise the following java files:
FileChooserExample.java
- In your editor or IDE, create a file known as
FileChooserExample.java
. - Then add the following code:
(a). FileChooserExample.java
Our class will do with some imports. Let’s go ahead and add them:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.FileChooser;
import javafx.stage.Stage;
Our class will do with some imports. Let’s go ahead and add them:
import java.io.File;
Extend the class
as shown below:
public class FileChooserExample extends Application {
Our class
will have the following methods:
void main(String[] args)
void start(Stage primaryStage)
The starting point of our Java app will be main method which we create as follows:
public static void main(String[] args) {
In this particular class
we will be overriding our void start(Stage primaryStage)
method.
Prepend the code>@Override</code modifier to your method. Then add implementation code as follows:
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("JavaFX App");
FileChooser fileChooser = new FileChooser();
fileChooser.setInitialDirectory(new File("src"));
fileChooser.setInitialFileName("myfile.txt");
/*
fileChooser.getExtensionFilters().addAll(
new FileChooser.ExtensionFilter("Text Files", "*.txt")
,new FileChooser.ExtensionFilter("HTML Files", "*.htm")
);
*/
Button button = new Button("Select File");
button.setOnAction(e -> {
File selectedFile = fileChooser.showOpenDialog(primaryStage);
System.out.println(selectedFile.getAbsolutePath());
});
VBox vBox = new VBox(button);
//HBox hBox = new HBox(button1, button2);
Scene scene = new Scene(vBox, 960, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
Here is the full code:
package com.jenkov.javafx.filechooser;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.FileChooser;
import javafx.stage.Stage;
import java.io.File;
public class FileChooserExample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("JavaFX App");
FileChooser fileChooser = new FileChooser();
fileChooser.setInitialDirectory(new File("src"));
fileChooser.setInitialFileName("myfile.txt");
/*
fileChooser.getExtensionFilters().addAll(
new FileChooser.ExtensionFilter("Text Files", "*.txt")
,new FileChooser.ExtensionFilter("HTML Files", "*.htm")
);
*/
Button button = new Button("Select File");
button.setOnAction(e -> {
File selectedFile = fileChooser.showOpenDialog(primaryStage);
System.out.println(selectedFile.getAbsolutePath());
});
VBox vBox = new VBox(button);
//HBox hBox = new HBox(button1, button2);
Scene scene = new Scene(vBox, 960, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
}
