I am now trying to make focus to FX FileDialog. When i click outside the dialog, dialog is outfocused. Its any way to make when i click outside, the dialog call any metod that make him visible (focused)? TY :)
I just tried any like this.
...focusedProperty().addListener((obs, oldVal, newVal) -> System.out.println(newVal ? "Focused" : "Unfocused"));
and maeby this way...
fileChooser.addEventHandler(WindowEvent.WINDOW_SHOWN, new EventHandler<WindowEvent>(){
#Override
public void handle(WindowEvent window)
{...
There is no way to handle focus using addEventHandler inside javafx.stage.FileChooser,
But you can simply use primaryStage.setAlwaysOnTop(true); to make your FileChooser always visible on top of other windows
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.FileChooser;
import javafx.stage.Stage;
public class JavaFXtest5 extends Application {
#Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Test");
FileChooser chooser = new FileChooser();
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
primaryStage.setAlwaysOnTop(true);
chooser.showOpenDialog(primaryStage);
primaryStage.setAlwaysOnTop(false);
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello Dialog!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
I was testing the MonologFX from JFXtras (v8.0-r5), but I got stuck with it!
Can anyone tell me how to check what was the button in the dialog that was pressed by the user? I tried in many ways, but no luck at all.
package javafx_jfxtras_monologfx;
import javafx.application.Application;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.event.EventHandler;
import javafx.event.ActionEvent;
import jfxtras.labs.dialogs.MonologFX;
import jfxtras.labs.dialogs.MonologFXButton;
import jfxtras.labs.dialogs.MonologFX.Type;
public class JavaFX_JFXtras_MonologFX extends Application
{
#Override
public void start(Stage stage)
{
MonologFX m = new MonologFX();
m.setModal(true);
m.setType(Type.QUESTION);
m.setTitleText("JFXtras MonologFX");
m.setMessage("Do you want to continue?");
m.setPos(698, 450);
MonologFXButton mb1 = new MonologFXButton();
mb1.setType(MonologFXButton.Type.YES);
mb1.setLabel("Continue");
m.addButton(mb1);
MonologFXButton mb2 = new MonologFXButton();
mb2.setType(MonologFXButton.Type.NO);
mb2.setLabel("Exit");
m.addButton(mb2);
Button btn = new Button();
btn.setText("Click the Button");
btn.setOnAction(new EventHandler<ActionEvent>()
{
#Override
public void handle(ActionEvent event)
{
System.out.println("Hello :)");
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
stage.setTitle("JavaFX - JFXtras MonologFX");
stage.setScene(scene);
stage.show();
m.show();
}
public static void main(String[] args)
{
launch(args);
}
}
But the controls in labs are experimental and Mark has not worked on this one for a long time. We don't take them out because someone may use them, but as of version 8u40 JavaFX has a dialog itself. https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/Dialog.html|
So I am trying to learn Java now that I know JavaScript and PHP. I am working in Netbeans with JavaFX and I am trying to create a program that creates 5 buttons. (This is modifying the code that comes with Netbeans when creating a new JavaFX Application.) If I change the y-argument of the scene to be less than the y of all of the buttons, it will not display the remaining buttons and it will not be able scroll down. This is what I have so far. How do I enable it to scroll down so all buttons can be seen? I know that I can just change the scene back to its old height but I want to learn about scrolling with JavaFX.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
import javax.swing.JScrollPane;
public class JavaFXApplication1 extends Application {
#Override
public void start(Stage primaryStage) {
GridPane root = new GridPane();
Button[] btn=new Button[5];
for(int i=0;i<5;i++){
btn[i] = new Button();
btn[i].setText(i+"");
GridPane.setRowIndex(btn[i],i);
root.getChildren().addAll(btn[i]);
btn[i].setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("This is a button");
}
});
}
Scene scene = new Scene(root, 300, 50);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Using ScrollPane to set root as:
ScrollPane sp = new ScrollPane();
sp.setContent(root);
Scene scene = new Scene(sp, 300, 50);
I'm making an applet using JavaFX 8 (via a JFXPanel) and was planning on using a Popup to display an area with a TextField in it. This works as expected, until the application loses focus. After that, I'm unable to make the TextField regain focus so you can't type in it any more. I've tried calling requestFocus() on the TextField but that didn't seem to do anything. The problem can be seen in the simple example below:
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.stage.Popup;
import javax.swing.*;
public class FXApplet extends JApplet {
protected Scene scene;
protected Group root;
#Override
public final void init() {
SwingUtilities.invokeLater(() -> initSwing());
}
private void initSwing() {
JFXPanel fxPanel = new JFXPanel();
add(fxPanel);
Platform.runLater(() -> {
initFX(fxPanel);
initApplet();
});
}
private void initFX(JFXPanel fxPanel) {
root = new Group();
scene = new Scene(root);
fxPanel.setScene(scene);
}
public void initApplet() {
Popup popup = new Popup();
popup.setAutoHide(false);
popup.getContent().add(new TextField());
popup.show(scene.getWindow());
}
}
I want to create simple gridPane, which would change its size after clicking a button. I have this code:
public class NewSimScene extends GridPane{
Button testButton;
public NewSimScene(){
setPrefSize(500, 500);
testButton = new Button("TEST");
testButton.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent t) {
Node source = (Node) t.getSource();
NewSimScene pane = (NewSimScene) source.getParent();
pane.setPrefSize(100, 100);
pane.setMaxSize(100, 100);
}
});
getChildren().add(testButton);
}
}
When I'm debugging, I can see that prefHeight and prefWidth values are changed, but there isn't any change in pane appearance. What could be a problem?
I don't know if it's relevant, but I'm running this pane in a separate scene, triggered from MenuBar.
there is no issue in your code, the Grid Pane's getting re-sized. Please have a look at the following code and feel free to comment if you are looking for something else !

}
#Override

GridPane grid = new NewSimScene();
((Group) scene.getRoot()).getChildren().addAll(grid);
stage.setScene(scene);

testButton.setOnAction(new EventHandler<ActionEvent>() {

}
