I have a problem with the BarChart only at the first upload, the categories labels surpass one another. it looks like this:
and from the second load, everything looks good:
the code:
#FXML
private ComboBox<String> subDepList;
#FXML
private BarChart<String, Number> subDepChart;
#FXML
private Button showButton;
#FXML
private Label sdErrorMessage;
#FXML
void setSubDepBarChart(Event event) {
subDepChart.getData().clear();
sdErrorMessage.setVisible(false);
boolean flag = true;
int sdId = -1;
try {
sdId = Integer.parseInt(subDepList.getValue());
} catch (NumberFormatException e) {
sdErrorMessage.setVisible(true);
flag=false;
}
if (flag) {
SubDepartment sd = Hospital.getInstance().getRealSubDepartment(sdId);
//setting sub-department bar chart
XYChart.Series<String, Number> set1 = new XYChart.Series<>();
set1.getData().add(new XYChart.Data<String, Number>("Patients", sd.getPatients().size()));
set1.getData().add(new XYChart.Data<String, Number>("Doctors", sd.getDoctors().size()));
set1.getData().add(new XYChart.Data<String, Number>("Nurses", sd.getNurses().size()));
set1.getData().add(new XYChart.Data<String, Number>("Reports", sd.getReports().size()));
subDepChart.getData().addAll(set1);
}
}
How can i fix it?

i am having a problem when i click on the button it doesn t work.
actually for the moment i am just asking that the button execute a system.out.println() just for the test. the name of the button is btndetailUser
listRechercheUser.setCellFactory(new Callback<ListView<User>, ListCell<User>>() {
#Override
public ListCell<User> call(ListView<User> p) {

cell = new ListCell<User>() {

super.updateItem(user, bln);
if (user != null) {
ImageView img;
String mm=user.getPath().trim();
if (mm.equals("fusee.png")){
img = new ImageView(new Image("mto/cr/images/"+mm));}
else{
img = new ImageView(new Image("mto/cr/images/mains-fonds.png"));
}

try something like,
btndetailUser.setOnAction(e -> {

I'd appreciate any help at all, I have spent hours at this to no avail.
So I need to add an instance of a class I found online called GridDisplay to the Parent root, as I need the scene to then display this for me. But I also need to use the fxml file to set up the root and hence the scene. Here is what I have so far:
#FXML private BorderPane mainPanel = new BorderPane();
#FXML private TilePane tilePane = new TilePane();
#FXML private Pane topCanvas = new Pane();
#FXML private Pane leftCanvas = new Pane();
#FXML private Pane rightCanvas = new Pane();
#FXML private Pane bottomCanvas = new Pane();
#FXML private ScrollPane scrollPane = new ScrollPane();
#FXML private Button stacksButton = new Button();
#FXML private Button queueButton = new Button();
#FXML private Button stepStacksButton = new Button();
#FXML private Button stepQueueButton = new Button();
private MazeSolver solver;
private GridDisplay gridDisplay;
private ArrayList<String> maze;
private String fileLocation;
private int height;
private int width;
#Override
public void start(Stage primaryStage) throws IOException, InterruptedException
{
solver = new MazeSolver(fileLocation);
int[] dimensions = solver.getDimensions();
this.width = dimensions[0];
this.height = dimensions[1];
maze = solver.getMazeLayout();
primaryStage.setTitle("Maze Solver");
//this is the root which uses the fxml file and in turn sets up the scene
Parent root = FXMLLoader.load(getClass().getResource("MazeApp.fxml"));
Scene scene = new Scene(root);
//Represents the grid with Rectangles
gridDisplay = new GridDisplay(height, width);
gridDisplay.setMaze(maze);
mainPanel = new BorderPane();
//here i set the scroll pane as the mainPanel's content
mainPanel.setCenter(scrollPane);
//and then set the gridDisplay as the scroll panes content
scrollPane.setContent(gridDisplay.getDisplay());
//re paints the grid and its boxes
gridDisplay.createElements();
primaryStage.setScene(scene);
primaryStage.show();
}
The order in which I do any of these things makes no difference, it just never shows. I am always left with the window and a blank space where the maze should be, like so: https://www.dropbox.com/s/rqxa9dy2w9lw4tz/Screenshot%202015-03-11%2022.01.46.png?dl=0 (sorry about linking, cant post image directly).
Any help would be greatly appreciated.
EDIT:
My GridDisplay class:
public class GridDisplay{
private static final double ELEMENT_SIZE = 30;
private static final double GAP = ELEMENT_SIZE / 90;
private TilePane tilePane = new TilePane();
private Group display = new Group(tilePane);
private int nRows;
private int nCols;
private ArrayList<String> maze = null;
public GridDisplay(int nRows, int nCols)
{
tilePane.setStyle("-fx-background-color: rgba(255, 215, 0, 0.1);");
tilePane.setHgap(GAP);
tilePane.setVgap(GAP);
setColumns(nCols);
setRows(nRows);
}
public void setColumns(int newColumns)
{
nCols = newColumns;
tilePane.setPrefColumns(nCols);
createElements();
}
public void setRows(int newRows)
{
nRows = newRows;
tilePane.setPrefRows(nRows);

tilePane.getChildren().clear();
for (int i = 0; i < nRows; i++) {

if(maze==null)
tilePane.getChildren().add(createElement(Color.RED));
else
{
Color color = Color.WHITE;

else
{
Color color = Color.WHITE;
if(Character.toString(maze.get(i).charAt(j)).equals("#"))
color = Color.BLACK;
if(Character.toString(maze.get(i).charAt(j)).equals("o"))
color = Color.GREEN;
if(Character.toString(maze.get(i).charAt(j)).equals("*"))
color = Color.RED;
tilePane.getChildren().add(createElement(color));
}
}
}
}
public void setMaze(ArrayList<String> maze)
{
this.maze = maze;
}
private Rectangle createElement(Color color) {
Rectangle rectangle = new Rectangle(ELEMENT_SIZE, ELEMENT_SIZE);
rectangle.setStroke(Color.BLACK);
rectangle.setFill(color);
return rectangle;
}
}
I cannot share the code for the xml as it will not paste into this window properly, here is a picture:
https://www.dropbox.com/s/27tbliubdlqdfzm/Screenshot%202015-03-12%2010.09.25.png?dl=0
Since your root is a BorderPane, you can just set the appropriate region in the code:
BorderPane root = FXMLLoader.load(getClass().getResource("MazeApp.fxml"));
Scene scene = new Scene(root);
//Represents the grid with Rectangles
gridDisplay = new GridDisplay(height, width);
gridDisplay.setMaze(maze);
ScrollPane scrollPane = new ScrollPane();
scrollPane.setContent(gridDisplay);
root.setCenter(scrollPane);
// etc
In my TableView I'm using a button as the placeholder when there are no items available in the table. And on click of this button I want to add a new row and then make the first cell in this row editable. I was able to successfully add new row, but the making the first cell editable does not work. I have tried using Platform.runLater to start the editing, but it doesn't work either. Below is the code for what I'm trying to do. Any help would be appreciated. Thanks
public class TableEditTest extends Application {
#Override
public void start(Stage primaryStage) {
TableColumn<Person, String> colA = new TableColumn<>("Name");
colA.setCellFactory(TextFieldTableCell.forTableColumn());
colA.setCellValueFactory(new PropertyValueFactory<>("name"));
TableColumn<Person, String> colB = new TableColumn<>("Age");
colB.setCellFactory(TextFieldTableCell.forTableColumn());
colB.setCellValueFactory(new PropertyValueFactory<>("age"));
TableColumn<Person, String> colC = new TableColumn<>("Gender");
colC.setCellValueFactory(new PropertyValueFactory<>("gender"));
colC.setCellFactory(TextFieldTableCell.forTableColumn());
TableView<Person> tableView = new TableView<>();
tableView.setEditable(true);
tableView.getColumns().addAll(colA, colB, colC);
Button btn = new Button();
btn.setText("Add Item");
btn.setOnAction((ActionEvent event) -> {
tableView.getItems().add(new Person());
// Edit the first cell
Platform.runLater(() -> {
tableView.edit(0, colA);
});
});
tableView.setPlaceholder(btn);
StackPane root = new StackPane();
root.getChildren().add(tableView);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
In the following code I have a TextField and a Button. I need to disable the Button when ever the TextField is empty, so that I can avoid entering empty values to the database. How can I make the button disabled ?
private VBox addVBox() {
VBox vb1 = new VBox();
vb1.setPadding(new Insets(15, 20, 25, 20));
vb1.setSpacing(15);
vb1.setStyle("-fx-background-color: #333333;");
final Label label = new Label("Staff Details");
label.setFont(Font.font("Arial", FontWeight.BOLD, 20));
label.setTextFill(Color.WHITE);
TableColumn sub = new TableColumn("Staff Name");
sub.setMinWidth(400);
sub.setCellValueFactory(
new PropertyValueFactory<Staff, String>("subName"));
table.setItems(data);
table.getColumns().addAll(sub);
addSubName = new TextField();
addSubName.setPromptText("Staff Name");
addSubName.setPrefSize(200, 30);
final Button b2 = new Button("Add");
b2.setFont(Font.font("Calibri", FontWeight.BOLD, 17));
b2.setPrefSize(70, 30);
b2.setStyle(" -fx-base: #0066ff;");
b2.setTextFill(Color.BLACK);
b2.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent e) {
msg = addSubName.getText();
try {
enterStaff();
} catch ( ClassNotFoundException | SQLException ex) {
Logger.getLogger(AddStaff.class.getName()).log(Level.SEVERE, null, ex);
}
data.add(new Staff(addSubName.getText()));
addSubName.clear();
}
});
hb.getChildren().addAll(addSubName, b2);
hb.setSpacing(5);
vb1.getChildren().addAll(label, table, hb);
return vb1;
}
Similar to Uluk's answer, but using the Bindings fluent API:
btn.disableProperty().bind(
Bindings.isEmpty(textField1.textProperty())
.and(Bindings.isEmpty(textField2.textProperty()))
.and(Bindings.isEmpty(textField3.textProperty()))
);
Also note that, this new overloaded method of Bindings is added in JavaFX-8 and not avaliable in JavaFX-2.
The other way can be using bindings:
final TextField textField1 = new TextField();
final TextField textField2 = new TextField();
final TextField textField3 = new TextField();
BooleanBinding bb = new BooleanBinding() {
{
super.bind(textField1.textProperty(),
textField2.textProperty(),
textField3.textProperty());
}
#Override
protected boolean computeValue() {
return (textField1.getText().isEmpty()
&& textField2.getText().isEmpty()
&& textField3.getText().isEmpty());
}
};
Button btn = new Button("Button");
btn.disableProperty().bind(bb);
VBox vBox = new VBox();
vBox.getChildren().addAll(textField1, textField2, textField3, btn);
use textProperty() Listener for TextField
try this...
Button b1 = new Button("DELETE");
b1.setFont(Font.font("Calibri", FontWeight.BOLD, 17));
b1.setPrefSize(100, 30);
b1.setStyle(" -fx-base: #ffffff;");
b1.setTextFill(Color.BLACK);
b1.setDisable(true); // Initally text box was empty so button was disable
txt1.textProperty().addListener(new ChangeListener<String>() {
#Override
public void changed(ObservableValue<? extends String> ov, String t, String t1) {
//System.out.println(t+"====="+t1);
if(t1.equals(""))
b1.setDisable(true);
else
b1.setDisable(false);
}
});
I can add SplitPane in a XYChart by clicking the "Add Pane" button, and it works fine.
Now I would like to remove SplitPane by clicking the "Remove pane" button.
Here is full code
public class SplitPaneFxTest extends Application {
SplitPane splitPane = new SplitPane();
double percSplit = 0.50;
int idxSplit = 0;
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(SplitPaneFxTest.class, args);
}
#Override
public void start(Stage primaryStage) {
primaryStage.setTitle("SplitPane Test");
Group root = new Group();
Scene scene = new Scene(root, 800, 650, Color.WHITE);
//CREATE THE SPLITPANE
splitPane.setPrefSize(scene.getWidth(), scene.getHeight());
splitPane.setOrientation(Orientation.VERTICAL);
//ADD LAYOUTS AND ASSIGN CONTAINED CONTROLS
BorderPane upperPane = new BorderPane();
HBox hbox = new HBox();
Button button1 = new Button("Add Pane");
hbox.getChildren().addAll(button1);
upperPane.setTop(hbox);
Button button2 = new Button("Remove Pane");
hbox.getChildren().addAll(button2);
upperPane.setTop(hbox);
BorderPane lowerPane = new BorderPane();
splitPane.getItems().addAll(upperPane);
splitPane.setDividerPosition(idxSplit, 0.70);
idxSplit++;
splitPane.getItems().addAll(lowerPane);
idxSplit++;
root.getChildren().add(splitPane);
primaryStage.setScene(scene);
primaryStage.show();
button1.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
BorderPane myborderpane = new BorderPane();
splitPane.getItems().addAll(myborderpane);
ObservableList<SplitPane.Divider> splitDiv = splitPane.getDividers();
System.out.println("splitDiv.size() "+splitDiv.size());
percSplit = 1/(double)(splitDiv.size()+1);
for (int i = 0; i< splitDiv.size(); i++) {
System.out.println("i "+i+" percSplit "+percSplit);
splitPane.setDividerPosition(i, percSplit);
percSplit += 1/(double)(splitDiv.size()+1);
}
}
});
}
}
Any help really appreciated.
You can store a list of inner panes and remove them based on this list:
final List<Pane> panes = new ArrayList<Pane>();
button1.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent e) {
BorderPane myborderpane = new BorderPane();
//adding
panes.add(myborderpane);
splitPane.getItems().addAll(myborderpane);
ObservableList<SplitPane.Divider> splitDiv = splitPane.getDividers();
System.out.println("splitDiv.size() " + splitDiv.size());
percSplit = 1 / (double) (splitDiv.size() + 1);
for (int i = 0; i < splitDiv.size(); i++) {
System.out.println("i " + i + " percSplit " + percSplit);
splitPane.setDividerPosition(i, percSplit);
percSplit += 1 / (double) (splitDiv.size() + 1);
}
}
});
button2.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent t) {
if (panes.size() > 0) {
// removing from both list and splitPane childs
Pane toDelete = panes.remove(0);
splitPane.getItems().remove(toDelete);
}
}
});
Also you can remove panes directly from ScrollPane.getChildren() but it can involve tricky and unreliable code to determine which pane to remove.
