I have a stage,it has two layers scene, if user click the button,then change to another layer, and also can change back. It just like swing cardlayout. How can i implement cardlayout in JAVAFX?
View RepliesI want to add only one button in a JFrame by using Mig Layout, dock south as BorderLayout.South does . Is it possible?
View Replies View RelatedI am developing a game where a player has to find a path in a maze. Right now the player can only click the buttons on the maze. I need an option to use the arrow keys.
I have picked up pieces from my code to illustrate my problem. Below is the code. If I call "AnyClass" in the "AppletClass" it works but when I call "MiddleClass" in the "AppletClass" and MiddleClass" calls "AnyClass" it does not work. In my project at www.hiredforoneday.com I call 4 panels in CardLayout before I call "AnyClass" which is the "Maze"

I noticed that when building a UI programmatically in several steps the width/height of the Pane I use for layout is -1/-1. I read that this is the case until the actual rendering happens. Is there a way to force that earlier? Suppose I wanted to size other UI components (which are not visible initially) according to the size of another pane. How do I do that? Binding the properties does not do the job in the case that those components are not necessarily visible at the same time. Is there a trick to achieve that?

I can not enter Latin letters with macron (Latvian specific characters) in JavaFX programs. Instead something like Latin letters with acute are entered.
what I need to enter is characters like this: Latin letter "a" with macron
Browser Test Page for Unicode Character 'LATIN SMALL LETTER A WITH MACRON' (U+0101)
what is actually entered: Latin letter "a" with acute
Browser Test Page for Unicode Character 'LATIN SMALL LETTER A WITH ACUTE' (U+00E1)
There are several keyboard layouts available for Latvian language input. Problem persists only on Windows OS for layouts using tilde key or apostrophe key as deadkeys. There are no problems with Microsoft Latvian (QWERTY) layout that uses ALTGR key as deadkey. There are also no problems on Linux OS using keyboard layouts that causes problems in Windows OS. I also noticed that character input works as expected int SceneBuilder 2.0 (I believe it has been build with javaFX). There are no problems also in java Swing GUI framework. So could this be a bug in JavaFX or am I missing some configuration settings?
How can I enter latin letters with macron using keyboard layout that uses tilde deadkey?
I have tried to implement MultipleSelectionModel with mostly success in TreeView, but definitely with quirks. I've looked at the implementation in TreeView and it's off putting to say the least. Hopefully it doesn't need to be that complicated. For now, all I need is it to handle SINGLE SELECTION, but it needs to be solid. I've put in a lot of println's to see what gets called. Most don't seem to be called. I'm relying on TreeView to look up the object being selected, I'm not sure if that's appropriate. The internal implementation seems to worry about tree state a lot.
It baffles me as to why there isn't a base class from which to extend or reuse? I'm doing this so I can delay a selection (make it vetoable), also to handle drag/drop more cleanly (so target won't move because of drag action).
private class VSelectionModel extends MultipleSelectionModel {
List<Integer> baseSelectedIndexes = new ArrayList<>();
ObservableList<Integer> selectedIndexes = FXCollections.observableList(baseSelectedIndexes);
List<Object> baseItems = new ArrayList<>();
ObservableList items = FXCollections.observableList(baseItems);

Why are the drop down boxes not stretched to the right all the way and why are they so tall?
So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
Method 1:
My IDE has a visual editor for creating Swing applications. The created application windows have no layout manager and use method "setBounds()" for placing Swing components on the application window. I have built an application that uses JInternalFrame. Each JInternalFrame is a separate and different "screen" for the user to interact with.
There are around 2,000 screens in the application and new screens are constantly being added as well as existing screens being modified. As a result, the top-level container - a JFrame - is a fixed size and is not resizable. I have now been asked to increase the size of the JFrame while maintaining the proportions of the screens.
Rather than manually editing the invocations of "setBounds()" on all the screens, any alternative way to achieve this? Also, is there a way to achieve this such that if, in future, the JFrame will again be resized, the screesn will automatically adjust?
I'm trying to build a GUI that must look lik on the image above. There must be three JPanles, the one above, with buttons and combo boxes, must have fixed height and all three must have fixed vertical gaps between them. I'm trying laout after layout but somehow it's not working. I'm allowed to use only standard Swing layouts.

How to change the location of a grid bag positioned component after it's already been added to the layout earlier?
Example is if I want component 1 to change from row 1 to row 2.
For example, say I have I BoxLayout with a few JButtons in it. How could I make it such that I could drag a JButton such that it could be in front or behind the others?
I've thought about using ComponentMover and just switching to a null layout right before moving it and switch it back right after like bellow, but I'm not sure how to make it keep the change in order.
import java.awt.LayoutManager;
import java.awt.event.MouseEvent;
public class LayoutComponentMover extends ComponentMover
{
private LayoutManager layout;

I am making an expert system using Jess about animals. I wanted to make an interface using Swing and so I did. I have a problem using group layouts. The application works fine but at the end a exceptions is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,
alignmentY=0.0,border=,flags=8388608,maximumSize=,minimumSize=,
preferredSize=,defaultIcon=,disabledIcon=,horizontalAlignment=LEADING,
horizontalTextPosition=TRAILING,iconTextGap=4,labelFor=,
text=The animal is a cheetah.,verticalAlignment=CENTER,
verticalTextPosition=CENTER] is not attached to a horizontal group
[Code] ....
The application ask the user some questions about the animal. When the expert system has enough information to know the animal it tells the name of the animal and shows a picture of it. The exception is thrown when the application has guessed the animal and shows the response.
Here is the code:
package xindria;
import javax.imageio.ImageIO;
import javax.swing.*;
import javax.swing.GroupLayout.SequentialGroup;
import java.awt.*;

I think the problem is related to the group layouts. I will attach the eclipse project too...
I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel();
applyVidBtn = new JButton("Apply Settings");
applyVidBtn.setVisible(false);
warningLbl = new JLabel("Note. Applying these settings causes a program restart.");
warningLbl.setVisible(false);

No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK);
scene.setFill(Color.BLACK);
scene.setFill() worked fine for previous versions of JavaFX.
How do you use GridBagLayout and CardLayout together?
I'm trying to add these buttons to a panel, but it breaks the GridBagLayout, here's what is in the doc;
Java Code:
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
[Code] .....
I'm trying to do:
Java Code:
JPanel m = new JPanel();
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
m.add(button, c);
[Code] .....
However it reverts as though it's using flowlayout. What is it I'm missing?

I'm trying to implement CSS in Java via a JEditorPane and an HTMLEditorKit. The CSS is included below. It *should* create a container with one on the left, small, and one on the right, large. It works flawlessly on JSFiddle [URL] ...., but on Java, it won't put the two divs next to each other. Is this a problem in Java/Netbeans or is it my problem? It creates the divs, but beneath each other. The JEditorPane is wide enough for all of them to fit.
Coding:
Java:
private void loadBulletins() {
//<editor-fold defaultstate="collapsed" desc="HTML/CSS Script">
String eBullStyles = "#divMsgs{ "

+ "margin: auto; "

I am trying to make a ChessBoard class composed of an array of JLabels inside a JPanel with a grid layout. I am also trying to override the getPreferredSize method so that the board will change size when I resize the main window (in another class in which I will instancize this class as part of a larger GUI). I got this kind of layout working before, but now I am trying to get it to work with multiple classes. However, after copying in the part of the previous code corresponding to the panel's layout, I am encountering some errors that I don't know how to solve. Specifically, when I try to override the getPreferredSize method, the compiler tells me "method does not override or implement a method from a super type, " and that it can't find the method "getPreferredSize"
Here's my code:
public class ChessBoard extends JPanel//the panel that this class extends is the boardHousing
{
//mental chess board piece array
Piece mentalBoard[][] = new Piece[8][8];
//actual GUI chessboard JLabel Array
static JLabel chessBoard[][] = new JLabel[8][8];
[Code] ....
I would just think that I was overriding the method incorrectly, but the weird thing is that I got that specific section of code to work before -- the only thing different now is that there are multiple classes, so my ChessBoard class itself is extending JPanel.
This code is directly from Swing: I'm using Eclipse and keep getting an error on line 10 saying :
"The type JTextField must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)."
