HiEveryone,
I'm new in JavaFx and my TextField shows at the middle of the frame but not at the top's position. Where am i suppose to be wrong? pls help..
Have a look into this screenshot..
But i want to set that TextField at the top ..
Here is Source code:
package sample;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
import javafx.scene.control.TextField;
public class Main extends Application {
#Override
public void start (Stage primaryStage){
primaryStage.setTitle("Modern web browser.");
WebView wv = new WebView();
WebEngine we = wv.getEngine();
we.load("http://www.google.com/");
TextField tf = new TextField("http://www.google.com/");
tf.setMaxHeight(Double.MIN_VALUE);
GridPane sp = new GridPane();
sp.getChildren().add(wv);
sp.getChildren().add(tf);
Scene scene = new Scene(sp, 600, 500);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Please help.. Thanks in Advanced!
EDITED
As #Nagesh Kumar answered me after using VBox getting this error:
Change your layout to VBox from GridPane as follows
VBox vbox = new VBox();
Now first add your TextField first so that it will be on top as follows
vbox.getChildren().add(tf);
then a WebView as follows
vbox.getChildren().add(wv);
Edit:
Yes you can try this
VBox vbox = new VBox(5);
5 pixel space between controls put in VBox

I have a Pane Object where users can drag and drop various ImageViews. For this, I used
pane.getChildren(imageViewObject)
method
Now, after replacing Pane with ScrollPane, it does not have this method. So I don't know how to get arrount this issue.
Thank you in advance
you can specify only one node with ScrollPane. To create a scroll view with more than one component, use layout containers or the Group class.
Pane pane = ...;
ScrollPane sp = new ScrollPane();
sp.setContent(pane);
Example:
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
/**

public class Test extends Application {
#Override
public void start(Stage stage) throws Exception {
VBox root = new VBox();
root.getChildren().addAll(new Button("button1"), new Button("button2"), new Button("button3"));
root.setSpacing(10);
root.setPadding(new Insets(10));
ScrollPane sp = new ScrollPane();
sp.setContent(root);
sp.setPannable(true); // it means that the user should be able to pan the viewport by using the mouse.
Scene scene = new Scene(sp, 100, 100);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I am searching for how to get the selected tab from a TabPane just by clicking on a button with JavaFX. I've tried to do it with the ChangeListener but it doesn't work yet.
So how can I do that?
As with many JavaFX controls there is a SelectionModel to get first.
tabPane.getSelectionModel().getSelectedItem(); To get the currently selected tab, or alternatively, getSelectedIndex() for the index of the selected tab.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TabSelect extends Application {
#Override
public void start(Stage primaryStage) {
TabPane tabPane = new TabPane();
tabPane.getTabs().addAll(new Tab("tab 1"),
new Tab("tab 2"),
new Tab("tab 3"));
Button btn = new Button();
btn.setText("Which tab?");
Label label = new Label();
btn.setOnAction((evt)-> {
label.setText(tabPane.getSelectionModel().getSelectedItem().getText());
});
VBox root = new VBox(10);
root.getChildren().addAll(tabPane, btn, label);
Scene scene = new Scene(root, 300, 300);
primaryStage.setScene(scene);
primaryStage.show();
//you can also watch the selectedItemProperty
tabPane.getSelectionModel().selectedItemProperty().addListener((obs,ov,nv)->{
primaryStage.setTitle(nv.getText());
});
}
public static void main(String[] args) { launch(args); }
}
tabPane.getSelectionModel().getSelectedIndex().
HiEveryone,
I'm new Javafx and trying to change the float of this button as to Right side from the current Left side.. How to do that?
I'm using simply Pane as a container at the moment.
Have a look into this screenshot:

public class Main extends Application {

WebView wv = new WebView();
wv.setLayoutX(0.0);

wv.setPrefHeight(Double.MAX_EXPONENT);
wv.setPrefWidth(Double.MAX_EXPONENT);

Use a HBox to hold the textfield and button, later add it to the Pane
HBox hbox = new HBox();
hbox.getChildren().addAll(tf, btn);
Pane sp = new Pane();
sp.getChildren().add(hbox);
sp.getChildren().add(wv);
I have a TextField in my program that will have data entered by the user, but I also have a variable value somewhere else that I need to permanently display at the end of my TextField. It cannot disappear when the user enters any data in the TextField. Can anyone give me a good implementation? Thanks.
[UserInput (miles)]
**Above is an example of what I am talking about. "Miles" needs to always be in the TextField while the UserInput is changing.
EDIT: "Implementation" was a bad choice of words. Let me rephrase, I can set up the field myself, but I am having trouble finding a way to set permanent text in a textfield. Just wondering if anyone knows an easy way.
You could put a transparent textfield over a label and bind the 2 together. Something like this but with better styling.
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Text extends Application {
#Override
public void start(Stage primaryStage) {
TextField txtUser = new TextField();
txtUser.setStyle("-fx-background-color: transparent;-fx-border-color:blue;");
Label txtBG = new Label(" (miles)");
Label labelUser = new Label();
labelUser.textProperty().bind(txtUser.textProperty());
Label labelAll = new Label();
labelAll.textProperty().bind(Bindings.concat(
labelUser.textProperty())
.concat(txtBG.textProperty()));
StackPane sp = new StackPane();
sp.getChildren().addAll(txtBG, txtUser);
sp.setPrefSize(100, 12);
VBox root = new VBox();
root.getChildren().addAll(sp,labelUser,labelAll);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("transparent text test");
primaryStage.setScene(scene);
primaryStage.show();
}
}
I would use a HBox instead of a stack pane but it's one way to satisfy the requirement that "miles" is 'inside' the texfield's borders.
This is a small example doing what you want ! I have used the focus property of textfield to add and remove miles from it !
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TextBinding extends Application {
#Override
public void start(Stage primaryStage) {
final TextField user = new TextField();
TextField demo = new TextField();
user.setStyle("-fx-background-color: transparent;-fx-border-color:blue;");
user.focusedProperty().addListener(new ChangeListener<Boolean>()
{
#Override
public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue)
{
if (newPropertyValue)
{
user.setText(user.getText().replace(" miles", ""));
}
else
{
user.setText(user.getText().concat(" miles"));
}
}
});
VBox root = new VBox();
root.getChildren().addAll(user,demo);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("transparent text test");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String args[]) {
launch(args);
}
}
I would like to align my button so that the first button is on the left of the screen and the other two are on the right. I am currently using HBox to try to position them but i cannot seem to able to figure out how to lay them out properly. The code below is what i am using now.
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;
public class ButtonTest extends Application {
private Button min, close, openfile;
public static void main(String[] args){
launch(args);
}
#Override
public void start(final Stage stage) throws Exception {
stage.setTitle("Button Test");
Group root = new Group();
BorderPane borderpane = new BorderPane();
setUpButtons();
HBox hbox = new HBox();
hbox.setSpacing(10);
hbox.getChildren().add(openfile);
HBox hbox1 = new HBox();
hbox1.setAlignment(Pos.CENTER_RIGHT);
hbox1.getChildren().addAll(min, close);
hbox.getChildren().add(hbox1);
HBox.setHgrow(hbox1, Priority.ALWAYS);
borderpane.setTop(hbox);
root.getChildren().add(borderpane);
Scene scene = new Scene(root,800,600);
stage.setFullScreen(true);
scene.getStylesheets().add("button.css");
stage.setScene(scene);
stage.show();
}
private void setUpButtons() {
close = new Button("x");
close.setId("closeBtn");
min = new Button("_");
min.setId("minBtn");
openfile = new Button("Open file");
openfile.setId("openFileBtn");
}
}
Any help would be appreciated
Thanks
Set the aligment of your outer HBox (hbox) to LEFT, and the aligment of your inner HBox (hbox1) to RIGHT.
Then you can have outer content on the left, and inner content on the right.
*EDIT: got your problem now. Stop using Group and add the borderpane directly to the Scene:
Scene scene = new Scene(borderpane,800,600);
