JavaFX 2.0 :: How To Set Divider Positions For SplitPane After Window Resizing
Sep 30, 2014
I would like to keep the same values of the positions for dividers (SplitPane) even if the width or the height of the window changes. I want to keep the proportion of the differents dividers. After resizing the window, the values of positions are not the sames ! I use this source without success :
stage.widthProperty().addListener(new ChangeListener<Number>() {
@Override public void changed( ObservableValue<? extends Number> observableValue, Number number, Number number2) {
sp.setDividerPositions(0.40f, 0.02f, 0.54f);
I have a problem with setting multiple splitpane divider positions. In my application there are multiple splitpanes (one inheriting the other). When resizing the scene (e.g. by double-click or mouse drag) the divider position default values (as set in the FXML) are not taken into account and the application therefore incorrectly displays the divider positions. For example, one pane that should be only 100px wide now spans over the half of the application. Its not very nice because one has to readjust the divider positions manually each time after resizing the window. At the same time, I dont want to set maximum values to keep the layout flexible.
I tried to solve this by adjusting the divider positions at a button click event (..setOnAction(new EventHandler<ActionEvent>()...) but when I click it only one splitpane at a time is adjusted. As I have 3 splitpanes I have to click the button 3 times to get all the adjustments. I am not sure whether this is because the click event is consumed after the first adjustment and subsequent repaint of the scene?
A sample code of what I have now would look like this:
I have a SplitPane, which is inside another SplitPane in the same tree hierarchy of the Scene. When I set the CSS class of the outer SplitPane, it always overwrites all CSS Settings of the inner one. How can I prevent it, so that e.g. I can assign a red divider for the outer and a green one for the inner SplitPane.
I'm having a problem with SplitPane (horizontal Flow). What I'm looking for is to find a way to maintain the left pane in the same position when the main window maximizes. I do not want the left pane to grow on its width. If I go into the AnchorPain Constraint in the Scene Builder and remove the right and left constraints, when I run the application, the left pane keeps its position, but it appears a gap between the two panes (the left pane and the right one).
I need to find the way to expand the right pane to the position where the left pane is.

I am new to javafx I start using it instead of swing i used the scene builder for my forms the problem i faced i don't know how to have main screen with menu bar at top and depending the select from the menu it will open other windows and those window must be inside my window just like for example netbeans.
I don't need to open new window in separate i need all windows inside my main window and controlling over them minimize maximize perhaps.
I am trying code that When i press a button(New user), i want the event to send me to a new windows that i have created in Scenebuilder... I dont know why it wont work, i get this exception:
Exception in thread "JavaFX Application Thread" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException at javafx.fxml.FXMLLoader$MethodHandler.invoke(Unknown Source) at javafx.fxml.FXMLLoader$ControllerMethodEventHandler.handle(Unknown Source) at com.sun.javafx.event.CompositeEventHandler.dispatchBubblingEvent(Unknown Source)
I've been having great success developing a drag-drop component for a JavaFX app, but I've run into an issue that has me completely stumped.
Specifically, I create a component that can be dragged around inside an anchor pane. That anchorpane is nested in a split pane, which is nested in another anchor pane (the control's root element).
The issue can be described this way:
Case #1: If I start the application as a small window, I can reposition the control by dragging it around the screen as I please. Case #2: If I start the application and maximize the window, again, I can drag the control around the screen as I please. Case #3: If I start the application, drag the control around a bit, then resize the window, the drag event handling breaks as follows:
1. The control drag events will fire normally only within the bounds of the anchor pane's previous size. 2. The mouse cursor's drag icon changes as I pass in or out of those bounds
I'm absolutely certain the anchorpane is resizing to match the parent window, otherwise Case #2 would not succeed. I'm at a complete loss as to determine why the drag events don't fire within the bounds of the resized window after they've been fired within the bounds of it's previous size.
Understand the mechanism I'm using to establish the drag handling: Once the controller is instantiated and added to the scene, an event listener on the class's parentProperty fires to attach the drag event handling to the parent node.
Previously, I was setting / clearing the drag handling on the parent node in the drag detection / drag dropped event handlers. I had suspected that adding / removing drag events was causing the trouble and opted for this solution to ensure that the same event instance was being used each time. Both methods have had the same result.

Here's the code that I'm using, redacted for clarity:
public class FileSystemNode extends AnchorPane { @FXML private AnchorPane fs_node_title; private FileSystemType mFsType; private Point2D mDragPoint;
there is no divider in the operation. Iadded a print i to confirm the loop works. I tried with and without the brackets..Can you use the i in the operations of the loop? I figured I could since printing it out give me a list of numbers
public class harmonique { public static void afficherHarmonique( int wholeNumber ) { int harmonique = 1; for( int i = 2; i <= wholeNumber + 1; i = i + 1 ) { System.out.println ("i =" + i); harmonique = harmonique + (1/i); System.out.println ("harmonique =" + harmonique);
So I got an interesting challenge today. I think logically I know what I have to do but I'm at a complete loss as for the actual coding implementation. So I have to develop this method called moveToBack(T entry). What this is meant to do is as implies, move entry to the back of my queue. As simple as it sounds, I know that I cant just move its position that simple. I know that I'll have to essentially remove whatever the desired value is, and then re-add it to the back of the queue. The interesting problem with this, however; is that I know that the FIFO property exists for queue's.
So if the desired entry to be moved is at the 3rd position of 4, I'd have to remove positions 1 and 2 to finally get to 3. But I want it to keep those values still. So I assume what I'll have to do is remove each element of the queue (it'll only be 5 entries max for the purpose of the project) and save it somewhere, then empty the queue and finally add the elements back in while waiting and putting the desired element to the last position.
If that's the case, I'm really curious on how I would do this. I have 4 files, 2 interfaces, the main class that contains the methods and what not for the queue, and a 4th class that'll be used for running test data and testing the methods of the program. Now, I wont add the interfaces code below because those are fine and all methods that need to be added are. I just gotta improve my moveToBack method so that it does what its supposed to. (I know I should have exceptions instead of my very poor else statements, but for this project it's not necessary.)
public abstract class NoDuplicatesQueueWilson<T> implements NoDuplicatesQueueInterfaceWilson<T> { private int MAX_QUEUE = 5; // Default array size, small for testing purposes private T[] items; // The array of the queue. private int front; // The first entered item of a queue. private int back; // The last entered item of a queue. private int count; // A counter.
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I am trying to develop a GUI through hard coding. I encountered a challenge:
I created a Jframe and onto this I added a JPanel. I assigned thge flow layout manager of the frame to null(because i want to do the positioning of my components manually)
The program is running perfect except when i click the maximise button of the frame, the JPanel does not change its size.
With Netbeans IDE - i found that the propert is Horizontal Resizable propert. I have tried to look for the method but in vain.
I am trying to develop identical things from hard coding and in drag and drop environment. so with drag and drop its easy but in hard coding how do I work it out?
Here is the code :
public class JPanelDemo { JFrame frame; JPanel panel; JPanelDemo(){ createFrame();
I have to write a resize method so that when my Bucket gets to a certain point, then it resizes the bucket when it is called. What is happening is, I am getting strange results when I run the method. My mean bucket length should be at 2.5 for the last insertion, but I am getting something like 0.1346. Here is my dictionary class
// The "Dictionary" class. // The Dictionary class implemented using hashing. Hash buckets are used. A dictionary contains a set of data elements with corresponding keys. Each element is inserted into the dictionary with a key. Later the key can be used to look up the element. Using the key, an element can be changed or it can be deleted from the dictionary. There is also an operation for checking to see if the dictionary is empty.
package dictionary; public class Dictionary { protected final static int MAX_BUCKETS = 1000; // number of buckets protected DictHashEntry[] buckets; // the bucket array private int collisionCount = 0;
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
I am trying to add scrollbars to my frame containing many different components and appearing when user resizes the window with the mouse adds pictures and admin of this online application adds labels or other components.
I want scrollbars to appear when the frame is resized and has components you don't see under so you can scroll down.
If I have for example this code, how i add the scrollbars when i make frame smaller ?
public class Test extends JFrame { private JPanel contentPane; /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() {
a) I have a Ball Object which implements the Runnable interface and traces the various positions of a ball.
b) I then have a Ball_Bounce JPanel inside a JFrame which creates two instances of the Ball object and then paints them to the JPanel.
As per my understanding, when the main() program in Ball_Bounce.java is started, there a total of three threads running in this program, one for each ball and one for the main(). What I cannot understand is whenever the balls collide, I end up getting the "Collision" message twice even though the collision is checked only in the main() thread.
[#]public class Ball implements Runnable { private boolean xUp, yUp, xUp1, yUp1; private int x, y, xDx, yDy; private final int MAX_X = 500, MAX_Y = 500; private boolean flag = true; private static Thread ball;
I am writing a small app to automate some actions on my computer this requires me to open an application and click on a button I am using
Process child0 = Runtime.getRuntime().exec("/home/user/application");
to do this. The problem is every time it opens at a different lcation on the screen so i cannot click on it using the robot class due to x,y coordinates being different every time. with selenium you can use .setlocation(x,y) method but how can this be done for other applications.
I have an assignment to create a circle with a radius of 40px in a 100px by 100px window and move the circle with the arrow keys.The circle can't move past the the edges of the window. I believe I have the code right but the window won't create the window or pane with a width of 100 px because of the close, minimize, maximize buttons. Is there a way to remove those or force JavaFX to create it with a width of 100px? Here's what I've got so far.
If I do try to do ChatFrame.setResizable(false); it gives me this error:

I have a WindowClosing(WindowEvent e) method, but when I close my window it isn't doing anything inside the method. I am making a launcher and I want to make it so when the actual game window is closed it makes the launcher window visible again.
Java Code: public void windowClosing(WindowEvent e) { this.jf.setVisible(true); } mh_sh_highlight_all('java');
That's my third day working in Java using Swing and the IntelliJ Idea IDE.I'm trying to do something as simple as displaying a PNG in a window, and I'm doing this:
public class AboutRapide { public JPanel mainPanel; private void createUIComponents() { mainPanel = new ImagePanel();
[cod]....
the problem is that, in the paintComponent method, the Image is never found when I run my app from the IDE, but it is when I run it from Finder in my Mac. Same application. I think it relates to how the application is launched so I guess what's a proper way to refer to a resource file with an image so it can be displayed no matter how the application is launched?Also if I generate a Jar for the application, as the resource gets into the Jar compressed file, it can't also be loaded.
I am trying to repaint a window from another class. the class Window handles an interface that displays pictures of movies. Via a JMenuBar you can add a new movie and its picture but in order for it to show in the Window i need to repaint certain aspects in the Window class GUI;
The window class constructor:
public Window() { addComponents(); configurFrame(); addMenu(); }
The functions i want to repaint:
public void repaintWindow() { this.getContentPane().validate(); this.getContentPane().repaint(); }
From my other class where i add a movie to an ArrayList i have made a "private Window myWindow;" there i call the function repaintWindow via mywindow.repaintWindow(); But this gives me an NullPointerException related to the repaintWindow function.
