I am doing a javafx project which if i click the button, the scene is showing, but if the scene is left open for few seconds, the scene will auto hide.
The actual scene is if i left it open, it will auto hide at the below of the main scene just like the button is pressed.
But i tried alot ways, the scene will either not hiding, or moving upward which if i click the button, the scene is at upward of the scene moving but not on the main scene.
If the scene is not on main scene, nothing will happen.But only if the scene is on main scene, the scene will auto hide and move downward just like when I click the button, the scene appear on the main scene from below and if i click close, the scene will go down and hide until i click again. when i click the button after a few inactive(like move the cursor), the scene will function as usual.
The code which i follow : Call another FXML within a stage

Here is an mcve version of the code you are following, to get you started :
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Test1 extends Application {
#Override
public void start(Stage primaryStage) {
try {
StackPane page = (StackPane) FXMLLoader.load(this.getClass().getResource("test1.fxml"));
Scene scene = new Scene(page);
primaryStage.setScene(scene);
primaryStage.show();
}
catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
test1.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.StackPane?>
<?import javafx.scene.layout.VBox?>
<StackPane id="StackPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity"
minWidth="-Infinity" prefHeight="300.0" prefWidth="500.0" xmlns="http://javafx.com/javafx/10.0.1"
xmlns:fx="http://javafx.com/fxml/1" fx:controller="Test1Controller">
<children>
<AnchorPane prefHeight="200.0" prefWidth="200.0" style="-fx-background-color: blue;">
<children>
<Button mnemonicParsing="false" onAction="#toggleStatus" text="Status" AnchorPane.leftAnchor="50.0" AnchorPane.topAnchor="100.0" />
</children>
</AnchorPane>
<VBox fx:id="statusContainer" maxHeight="100.0" prefHeight="100.0" style="-fx-background-color: yellow;" translateY="100.0" StackPane.alignment="BOTTOM_LEFT" />
</children>
</StackPane>
and its controller:
import javafx.animation.TranslateTransition;
import javafx.fxml.FXML;
import javafx.scene.layout.VBox;
import javafx.util.Duration;
public class Test1Controller {
#FXML private VBox statusContainer;
private TranslateTransition showStatus;
private TranslateTransition hideStatus;
private boolean showsStatus = false;
#FXML void initialize() {
showStatus = new TranslateTransition(Duration.millis(250), statusContainer);
showStatus.setByY(-100.0);
showStatus.setOnFinished(event -> showsStatus = true);
hideStatus = new TranslateTransition(Duration.millis(250), statusContainer);
hideStatus.setByY(100.0);
hideStatus.setOnFinished(event -> showsStatus = false);
}
public void toggleStatus() {
if( showsStatus ) {
showStatus.stop();
hideStatus.play();
}
else {
hideStatus.stop();
showStatus.play();
}
}
}
Edit: you can add auto-hide of the sliding node to the controller:
public class Test1Controller {
#FXML private VBox statusContainer;
private TranslateTransition showStatus;
private TranslateTransition hideStatus;
private boolean showsStatus = false;
private static final int AUTO_HIDE_DEALY = 5;
#FXML void initialize() {
showStatus = new TranslateTransition(Duration.millis(250), statusContainer);
showStatus.setByY(-100.0);
showStatus.setOnFinished(event -> {
showsStatus = true;
autoHide();
});
hideStatus = new TranslateTransition(Duration.millis(250), statusContainer);
hideStatus.setByY(100.0);
hideStatus.setOnFinished(event -> showsStatus = false);
}
public void toggleStatus() {
if( showsStatus ) {
hide();
}
else {
show();
}
}
private void show(){
hideStatus.stop();
showStatus.play();
}
private void hide(){
showStatus.stop();
hideStatus.play();
}
private void autoHide() {
Duration duration = Duration.seconds(AUTO_HIDE_DEALY);
PauseTransition transition = new PauseTransition(duration);
transition.setOnFinished(evt ->{
if( showsStatus ) {
hide();
}
});
transition.play();
}
}

I have created a custom Master-Detail pane for my project, where i use a split pane, in each i have two Anchor Panes. In one there is a TableView filled with Users (ObservableList). On each row (User) i have implemented a ChangeListener
table.getSelectionModel().selectedItemProperty().addListener(listElementChangeListener());
when the row is selected, i pass the UserObject for my DetailPane, and visualize User data in TextFields as detail. I have implemented controls, to understand if the User is under modification in Detail, and if so i would like to prevent a row change in my TableView. I tried to remove the ChangeListener from the TableView when i modify the User, but it dosent work well. I'm thinking of a solution like setting the focus and holding it on the row until i cancel or save the User modified.
Is there any nice solutions?
Thanks for your help.
I would probably approach this a little differently. I would bind the controls in the "detail view" bidirectionally to the properties in the User object. That way they will be updated in the object (and the table) as the user edits them. If you like, you can also provide a "cancel" button to revert to the previous values.
Here's a complete solution that uses this approach:
User.java:
package usermasterdetail;
import javafx.beans.property.BooleanProperty;
import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class User {
private final StringProperty firstName = new SimpleStringProperty();
private final StringProperty lastName = new SimpleStringProperty();
private final BooleanProperty admin = new SimpleBooleanProperty();
public User(String firstName, String lastName, boolean admin) {
setFirstName(firstName);
setLastName(lastName);
setAdmin(admin);
}
public final StringProperty firstNameProperty() {
return this.firstName;
}
public final String getFirstName() {
return this.firstNameProperty().get();
}
public final void setFirstName(final String firstName) {
this.firstNameProperty().set(firstName);
}
public final StringProperty lastNameProperty() {
return this.lastName;
}
public final String getLastName() {
return this.lastNameProperty().get();
}
public final void setLastName(final String lastName) {
this.lastNameProperty().set(lastName);
}
public final BooleanProperty adminProperty() {
return this.admin;
}
public final boolean isAdmin() {
return this.adminProperty().get();
}
public final void setAdmin(final boolean admin) {
this.adminProperty().set(admin);
}
}

new User("Michael", "Brown", true)
);

If you prefer the user experience you described, you can (as #SSchuette describes in the comments), just bind the table's disable property to the modifying property. This will prevent the user from changing the selection while the data is being edited (i.e. is not consistent with the data in the table). For this you just need the modifying property in the model:
package usermasterdetail;
import javafx.beans.property.BooleanProperty;
import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
public class DataModel {
private final ObservableList<User> userList = FXCollections.observableArrayList(
new User("Jacob", "Smith", false),
new User("Isabella", "Johnson", true),
new User("Ethan", "Williams", false),
new User("Emma", "Jones", true),
new User("Michael", "Brown", true)
);
private final ObjectProperty<User> currentUser = new SimpleObjectProperty<>();
private final BooleanProperty modifying = new SimpleBooleanProperty();
public final ObjectProperty<User> currentUserProperty() {
return this.currentUser;
}
public final usermasterdetail.User getCurrentUser() {
return this.currentUserProperty().get();
}
public final void setCurrentUser(final usermasterdetail.User currentUser) {
this.currentUserProperty().set(currentUser);
}
public ObservableList<User> getUserList() {
return userList;
}
public final BooleanProperty modifyingProperty() {
return this.modifying;
}
public final boolean isModifying() {
return this.modifyingProperty().get();
}
public final void setModifying(final boolean modifying) {
this.modifyingProperty().set(modifying);
}
}
then in the table controller you can bind the disable property to it:
package usermasterdetail;
import javafx.fxml.FXML;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.CheckBoxTableCell;
public class TableController {
#FXML
private TableView<User> table ;
#FXML
private TableColumn<User, String> firstNameColumn ;
#FXML
private TableColumn<User, String> lastNameColumn ;
#FXML
private TableColumn<User, Boolean> adminColumn ;
private DataModel model ;
public void initialize() {
firstNameColumn.setCellValueFactory(cellData -> cellData.getValue().firstNameProperty());
lastNameColumn.setCellValueFactory(cellData -> cellData.getValue().lastNameProperty());
adminColumn.setCellValueFactory(cellData -> cellData.getValue().adminProperty());
adminColumn.setCellFactory(CheckBoxTableCell.forTableColumn(adminColumn));
}
public void setDataModel(DataModel dataModel) {
if (model != null) {
model.currentUserProperty().unbind();
}
this.model = dataModel ;
dataModel.currentUserProperty().bind(table.getSelectionModel().selectedItemProperty());
table.setItems(model.getUserList());
table.disableProperty().bind(model.modifyingProperty());
}
}
The only place there is a bit of work to do is to make sure the modifying property is set to true any time the data are not in sync (though it sounds like you have already done this):
package usermasterdetail;
import javafx.beans.value.ChangeListener;
import javafx.fxml.FXML;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TextField;
public class UserEditorController {
#FXML
private TextField firstNameField ;
#FXML
private TextField lastNameField ;
#FXML
private CheckBox adminCheckBox ;
private DataModel model ;
private ChangeListener<Object> modifyingListener = (obs, oldValue, newValue) -> {
if (model != null) {
if (model.getCurrentUser() == null) {
model.setModifying(false);
} else {
model.setModifying(! (model.getCurrentUser().getFirstName().equals(firstNameField.getText())
&& model.getCurrentUser().getLastName().equals(lastNameField.getText())
&& model.getCurrentUser().isAdmin() == adminCheckBox.isSelected()));
}
}
};
private ChangeListener<User> userListener = (obs, oldUser, newUser) -> {
if (oldUser != null) {
oldUser.firstNameProperty().removeListener(modifyingListener);
oldUser.lastNameProperty().removeListener(modifyingListener);
oldUser.adminProperty().removeListener(modifyingListener);
}
if (newUser == null) {
firstNameField.clear();
lastNameField.clear();
adminCheckBox.setSelected(false);
} else {
firstNameField.setText(newUser.getFirstName());
lastNameField.setText(newUser.getLastName());
adminCheckBox.setSelected(newUser.isAdmin());
newUser.firstNameProperty().addListener(modifyingListener);
newUser.lastNameProperty().addListener(modifyingListener);
newUser.adminProperty().addListener(modifyingListener);
}
};
public void setDataModel(DataModel dataModel) {
if (this.model != null) {
this.model.currentUserProperty().removeListener(userListener);
}
this.model = dataModel ;
this.model.currentUserProperty().addListener(userListener);
}
public void initialize() {
firstNameField.textProperty().addListener(modifyingListener);
lastNameField.textProperty().addListener(modifyingListener);
adminCheckBox.selectedProperty().addListener(modifyingListener);
}
#FXML
private void cancel() {
if (model != null) {
firstNameField.setText(model.getCurrentUser().getFirstName());
lastNameField.setText(model.getCurrentUser().getLastName());
adminCheckBox.setSelected(model.getCurrentUser().isAdmin());
}
}
#FXML
private void update() {
if (model != null && model.getCurrentUser() != null) {
model.getCurrentUser().setFirstName(firstNameField.getText());
model.getCurrentUser().setLastName(lastNameField.getText());
model.getCurrentUser().setAdmin(adminCheckBox.isSelected());
}
}
}
This solution requires an additional button to force the update in the data (and table):
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.TextField?>

<?import javafx.scene.control.Button?>

<ColumnConstraints halignment="RIGHT" hgrow="NEVER"/>
<ColumnConstraints halignment="LEFT" hgrow="SOMETIMES"/>
</columnConstraints>
<padding>
<Insets top="5" left="5" bottom="5" right="5"/>
</padding>
<Label text="First Name:" GridPane.columnIndex="0" GridPane.rowIndex="0"/>
<Label text="Last Name:" GridPane.columnIndex="0" GridPane.rowIndex="1"/>
<Label text="Admin Priviliges:" GridPane.columnIndex="0" GridPane.rowIndex="2"/>
<TextField fx:id="firstNameField" GridPane.columnIndex="1" GridPane.rowIndex="0"/>
<TextField fx:id="lastNameField" GridPane.columnIndex="1" GridPane.rowIndex="1"/>
<CheckBox fx:id="adminCheckBox" GridPane.columnIndex="1" GridPane.rowIndex="2"/>
<HBox spacing="5" alignment="CENTER" GridPane.columnIndex="0" GridPane.rowIndex="3" GridPane.columnSpan="2">
<Button text="Update" onAction="#update"/>
<Button text="Cancel" onAction="#cancel"/>
</HBox>
</GridPane>
TableView multi selection returns one of the selected objects as null. This doesn't happen every time but happens most of the times when i try to select two rows in the table.similar to the issue defined in this question
Best way of reproducing the issue is , try selecting two sequential rows .

1: add a default cell factory to your TableView
2: override either updateItem or updateIndex
hope it helpls
THIS PROBLEM OCCURS ONLY ON OSX EL CAPITAN
There's a ListView, and when the user puts the mouse over a ListCell a popup with a picture related to the 'pointed' item should appear next to the cell.

}
}
It works fine if I don't move the window that contains the ListView.
On the contrary the Popup with the picture is displayed with an unexpected offset: the problem is that Cell's coordinates I get from "thisCell.localToScreen(thisCell.getBoundsInLocal())" aren't exact if I first moved the window.
What could the problem be?
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,

Thanks in advance.
In a Table.java change all getters and setters names,
change getr* to getR*
change setr* to setR*
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. :)
I use javafx2 control TableView to dispay records in the database(I have 20 records now).
And when display the record,I want to add button in each row.
so I search lots of article use google,and write some code below.
the key code is:
protected void updateItem(Long item, boolean empty) {
super.updateItem(item, empty);
if(empty) {
setText(null);
setGraphic(null);
} else {
final Button button = new Button("modifty");
setGraphic(button);
setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
}
}
I debug this code,the param "empty" would never be "false",
so the button would never be display in the table view,
can anyone help me? thanks
below is the complete code(java and fxml):

You haven't set a cellValueFactory for your action column, so it is always empty.
A simple way to do this is just to set the cell value to the id of the record.
actionCol.setCellValueFactory(
new PropertyValueFactory<CustomerDto,Long>("id")
);
Additionally, I created a simple example for creating a table with Add buttons in it, which you could reference if needed.
