I want to set file filters in a JavaFX FileChooser but I could not find a way to do it.
My code:
FileChooser fc = new FileChooser();
fc.setTitle("My File Chooser");
File f = fc.showOpenDialog(primaryStage);
System.out.println(f);
You could do:
FileChooser.ExtensionFilter extFilter = new FileChooser.ExtensionFilter("TXT files (*.txt)", "*.txt");
chooser.getExtensionFilters().add(extFilter);
Here is a simple example:
public class ExtensionFilterExample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(final Stage primaryStage) {
primaryStage.setTitle("Extension Filter Example");
final Label fileLabel = new Label();
Button btn = new Button("Open FileChooser");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
FileChooser fileChooser = new FileChooser();
// Set extension filter
FileChooser.ExtensionFilter extFilter =
new FileChooser.ExtensionFilter("TEXT files (*.txt)", "*.txt");
fileChooser.getExtensionFilters().add(extFilter);
// Show open file dialog
File file = fileChooser.showOpenDialog(primaryStage);
if (file != null) {
fileLabel.setText(file.getPath());
}
}
});
VBox vBox = new VBox(30);
vBox.getChildren().addAll(fileLabel, btn);
vBox.setAlignment(Pos.BASELINE_CENTER);
StackPane root = new StackPane();
root.getChildren().add(vBox);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
