My project does not run after export, but in netbeans 8.2 working.
This happens only when load exceeding 14 images (13 images works fine). Here my code and the jarerror.
In debug netbeans and eclipse work all.
I tried with scene builder and without, with every IDE and got same error.

I am trying to figure out how to make my VBox, only go to the size of 300 pixel's wide, but i would like to have it at say 250 pixels wide when the program is initialized, then when the user clicks full screen, I want it to expand, but not necessarily with the entire space it would have. I want it to only go to 300 pixels (and have the 3 buttons inside do the same thing) but I'm not sure how to do that. I'm having trouble determining PrefSize and CompSize actual meanings and uses. Any help would be great.
I am also having kind of the same problem with the Label, inside the HBox, that is inside a SplitPane, that is inside a BorderPane. Any explanation of why what you are suggesting will work, will help me with future problems like this. Thank you

I actually put my VBox inside an AnchorPane, and attached it to the anchors, and everything worked perfectly after I set my preferred height and width.
This question already has answers here:
Center stage on parent stage
(2 answers)
Closed 4 years ago.
I am trying to pop-up the box in the center of the application when I resize the application or move it.
I tried with css alignment and also using Java. Is it possible if I don't use pane and directly add box in the scene?
Here is my code:
public Boolean call(String question) {
final Stage dialogStage = new Stage(StageStyle.UNDECORATED);
dialogStage.initModality(Modality.WINDOW_MODAL);
dialogStage.initOwner(owner);
dialogStage.setTitle("ConfirmTitle"); // WIP, waiting for the strings&trans
final Button ok = new Button(
nmsGuiContainer.getI18nService().getMessage("com.mlnms.gui.fmwk.main.container.ok")); // WIP,
// waiting
// for
// the
// strings&trans
ok.getStyleClass().add(HTML_POPUP_BUTTON_STYLE);
final Button cancel = new Button(
nmsGuiContainer.getI18nService().getMessage("com.mlnms.gui.fmwk.main.container.cancel")); // WIP,
// waiting
// for the
// strings&trans
cancel.getStyleClass().add(HTML_POPUP_BUTTON_STYLE);
final Text text = new Text(question);
text.getStyleClass().add(HTML_POPUP_STYLE);
final Insets ins = new Insets(10);
final VBox box = new VBox();
box.setAlignment(Pos.BOTTOM_CENTER);
box.setSpacing(10);
box.setPadding(ins);
final HBox buttons = new HBox(10);
buttons.getChildren().addAll(ok, cancel);
buttons.setAlignment(Pos.CENTER);
buttons.setPadding(ins);
box.getChildren().addAll(text, buttons);
box.getStyleClass().add(HTML_POPUP_STYLE);
StackPane pane = new StackPane();
pane.setAlignment(box, Pos.CENTER);
pane.getChildren().add(box);
Scene scene = new Scene(pane);
try {
URL javafxCss = nmsGuiContainer.getBundleContext().getBundle()
.getResource(NmsGuiContainer.JAVAFX_CSS_URL);
scene.getStylesheets().add(javafxCss.toExternalForm());
} catch (Exception e) {
LOGGER.error("Cannot load the CSS file for JavaFX components ", e);
}
dialogStage.setScene(scene);
ok.setCancelButton(false);
final boolean[] res = new boolean[1];
ok.setOnAction(new CloseDialogHandler(dialogStage, res));
cancel.setCancelButton(true);
cancel.setOnAction(new CloseDialogHandler(dialogStage, null));
dialogStage.centerOnScreen();
nmsGuiContainer.fadeContainer();
dialogStage.showAndWait();
nmsGuiContainer.unfadeContainer();
return res[0];
}
Here is a screenshot of the alertbox:
The Stage.initOwner() method does exactly what you need. While you do call it in your example code, I do not know what owner you are passing to it.
Here is a sample that demonstrates how to do this.
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Alert;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
VBox root = new VBox(10);
root.setAlignment(Pos.CENTER);
root.setPadding(new Insets(10));
Button btnShowAlert = new Button("Show Alert!");
// Set the action to show the alert
btnShowAlert.setOnAction(e -> {
Alert alert = new Alert(Alert.AlertType.WARNING);
alert.setHeaderText("This is centered over the main window!");
alert.setContentText("Move the main window and show the alert again!");
alert.initOwner(primaryStage);
alert.showAndWait();
});
root.getChildren().add(btnShowAlert);
primaryStage.setTitle("Centered Alerts");
primaryStage.setScene(new Scene(root));
primaryStage.setWidth(500);
primaryStage.setHeight(300);
primaryStage.show();
}
}
I need to change the gray background color of the ScrollPane so where you see WHITE and BOLD Labels i want the background to be white.

You have to modify the .viewport color of the ScrollPane with css:
CSS code:
/*The ViewPort of the ScrollPane */
.scroll-pane .viewport {
-fx-background-color: white; /*or whatever you want*/
}
.scroll-pane {
-fx-background-color:transparent;
}
And change these lines of code from your application:
//........
//.........
root.setPadding(new Insets(15));
root.setTop(menuBar);
//root.setCenter(hbox);
Scene scene = new Scene(root, WINDOW_WIDTH, WINDOW_HEIGHT);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
stage.setTitle("Dummy Title");
stage.setScene(scene);
stage.show();
//........
//.........
Finally mention that the css file which contains the css code,in this example has to be in the same source folder as the Application.java file.
I guess your question is, how to apply a white background?
via css-style (an entry in your css-File would be better for that):
root.setStyle("-fx-background-color:white");
menuBar.styleProperty().bind(root.styleProperty());
via api
Background background = new Background(new BackgroundFill(Color.WHITE, CornerRadii.EMPTY, Insets.EMPTY));
root.setBackground(background);
menuBar.setBackground(background);
There is concept of my JavaFX applictions:
All screens in one ScrollPane.
For example, if user click on button "Options" in loginScreen i want to animate Y-value of ViewPort to move it to optionsScreen.
How can i programmatically move viewport of ScrollPane with smooth animation?
Or you can offer better idea?
How can I programmatically move viewport of ScrollPane with smooth animation?
You can use a combination of Timeline and vvalueProperty of ScrollPane to perform a smooth animation of scrolling.
Here is a simple application where you I have three sections
Top
Center
Bottom
I am changing the vvalue of the ScrollPane through a Timeline on the action of the button.
The vvalue can have a value between 0.0 to 1.0, so you may have to do your own calculations to find the exact value which you want to be assigned to it.
The KeyValue performs the operation on scrollRoot.vvalueProperty().
The KeyFrame for the complete timeline is set at 500 milliseconds. You may increase or decrease it depending on the time you want the animation to run.

Output
Following the tutorial here I tried to create a Tooltip on a ScrollPane using the following code:
final ScrollPane scroll = new ScrollPane();
scroll.addEventHandler(MouseEvent.MOUSE_MOVED, new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent t) {
pointer = MouseInfo.getPointerInfo();
point = pointer.getLocation();
color = robot.getPixelColor((int) point.getX(), (int) point.getY());
Tooltip tooltip = new Tooltip();
tooltip.setText(" " + color);
tooltip.activatedProperty();
scroll.setTooltip(tooltip);
System.out.println("Color at: " + point.getX() + "," + point.getY() + " is: " + color);
}
});
The tooltip however refuses to show itself on the ScrollPane but the output of "Color at: ..." is being printed so I am sure that handle is being called.
EDIT : On the suggestion of jewelsea , I tried putting the eventHandler on the content ,rather than the pane, but to no effect.
If I understand what you're trying to do, you really only need to install the tooltip once, and then just modify its text as the mouse moves.

Color color = pixelReader.getColor(x, y);
