GridLayout in panel not showing buttons

GridLayout in panel not showing buttons - java

I created a class that extends JPanel called GamePane which on creation sets the layout to a GridLayout and then adds buttons one at a time:
public class GamePane extends JPanel {
private JButton[][] buttons;
private final int sizeX, sizeY;
private Partida partida;
public GamePane(int sizeX, int sizeY, Partida p) {
super();
this.sizeX = sizeX;
this.sizeY = sizeY;
this.partida = p;
this.setLayout(new GridLayout(sizeX + 1, sizeY + 1));
buttons = new JButton[sizeX + 1][sizeY + 1];
for (int y = 0; y < sizeY + 1; y++) {
for (int x = 0; x < sizeX + 1; x++) {
JButton button = new JButton();
button.addActionListener(new ListenerGameButton(x, y, this));
this.add(button);
button.setBackground(Color.yellow);
button.setVisible(true);
buttons[x][y] = button;
}
}
The panel initialization is done on the parent JDialog:
gamePane = new GamePane(sizeX, sizeY, parentPartida);
And here's how it looks in the NetBeans editor: (The selected frame being an instance of GamePane)
Then when testing it out it doesn't show the buttons:
This is the class of the parent JDialog where the child GamePane is located, most of the code is autogenerated by Netbeans:
public class gameDialog extends javax.swing.JDialog {
private final int sizeX, sizeY;
private Partida parentPartida;
public gameDialog(java.awt.Frame parent, boolean modal, int sizeX, int sizeY, Partida parentPartida)
{
super(parent, modal);
this.parentPartida = parentPartida;
this.sizeX = sizeX;
this.sizeY = sizeY;
initComponents();
}

The initComponents() method is generated by NetBeans and that's where the GamePane is created and later on the frame is packed at the end of initComponents() by calling pack()
So, what am I doing wrong? Thanks in advance!

There is no problem with your code. It is perfectly working fine.
JDialog dialog = new JDialog();
dialog.getContentPane().add(new GamePane(10, 10));
dialog.pack();
dialog.setVisible(true);
And i got the below.

How to calculate dimensions of a HTML formatted JComponent?

I am designing a Swing form using the GUI builder of Netbeans, and I'm using HTML to word wrap a JRadioButton. That works, but now the encapsulating JFrame does not resize the JFrame to fit the contents. I'm using the default GUI builder's LayoutManager, GroupLayout.
I tried to calculate the height of the component after it is word wrapped by HTML. That worked (see code below), but after setting the size and preferred size of the JRadioButton, the window does not get resized.
How can I fix it?
private void recalculateSize(JComponent component, int width) {
View v = (View) component.getClientProperty(javax.swing.plaf.basic.BasicHTML.propertyKey);
float preferredSpan = v.getPreferredSpan(View.Y_AXIS);
int height = component.getHeight();
float margin = height - preferredSpan;
Dimension actualSize = getActualSize(component, width);
int actualHeight = (int) (actualSize.height + margin);
Dimension d = new Dimension(component.getPreferredSize().width, actualHeight);
component.setPreferredSize(d);
component.setSize(d);
// This height is the real height. I tested it setting the background
// color to red.
System.out.println("Actual height: " + actualHeight);
}
private static Dimension getActualSize(JComponent component, int width) {
View view = (View) component.getClientProperty(javax.swing.plaf.basic.BasicHTML.propertyKey);
view.setSize(width, 0);
float w = view.getPreferredSpan(View.X_AXIS);
float h = view.getPreferredSpan(View.Y_AXIS);
return new java.awt.Dimension((int) Math.ceil(w), (int) Math.ceil(h));
}
Below is the whole code. Since it is generated by the GUI builder, it it hard to remove the unnecessary code.

Thanks in advance

The group layout is intended for UI designing software, rather than humans. Avoid using it.
Instead, you have quite a selection of built-in layout managers, and it's not very difficult to implement a custom one in case you need special behavior that cannot (or should not) be achieved by nesting layouts (by nesting components with different layout).
I'm not sure what's the layout you're trying to achieve, but if you're referring to a list of images that you can scroll down in a JScrollPane or something like that, you should consider FlowLayout or even BoxLayout. There are other layouts you can wield to this task, but these two would be the simplest to use.

Sliding any JPanel

Im trying to make a universal class for sliding two any-samesized JPanels but when I use it, the one to get slid just disappears. What I also noticed is that the JPanel "innerPanel"'s width is being reset (when transisting a 200,200 panel) from 400,200 that the size gets reset to 200,200 after the Thread is started

Yes, I know the class extends JFrame, I'm just using that for testing purposes. (I'm also not sure how to fix the indenting on this page)

Components in Swing are generally under the control of a layout manager. To achieve what you are trying to do, you would actually be better of creating an animated layout manager.
I suggest you take a look at...
The Universal Tween Engine
Sliding layout
You could also take a look at Animations when using Gridbag Layout. (shameless plug)

Adding JCheckBox Array to JPanel in Netbeans

I've been trying to add an array of JCheckBoxes to a JPanel in Netbeans that has been automatically generated by the Netbeans GUI, when I create an array of the JCheckBoxes and then try to add them to the JPanel using JPanel.add(jCheckboxArray[x]) , the program compiles ok but they don't appear.
I've created an array like so:
// custom private member variables
private javax.swing.JCheckBox[] jCheckboxArray;
//
int CheckBoxNumber = 5;
jCheckboxArray = new javax.swing.JCheckBox[CheckBoxNumber];
for(int x = 0; x < CheckBoxNumber ; x++) {
jCheckboxArray[x] = new javax.swing.JCheckBox();
jCheckboxArray[x].setText("CheckBox " + x);
}
I've tried setting viable but no result, and all the examples online appear to make a reference to adding the JPanel to a JFrame however no JFrame exists in the auto-generated code probably because the auto generated class extends javax.swing.JFrame.
Any help greatly appreciated.
Here is the entire code:

Allow user handwriten marking on images - Java, Swing

I am developing an application using Java, Swing. It will be mainly used in order to study oscillograms against pentagrams for medical purposes. It is wished that the user can keep notes on top of the images (presumably something like the pencil used in Window's paint).
Please, keep in mind that every time the user loads an image, the following mouse motion listener gets attached to it (in order to make the image draggable for usability reasons):
public class DragMouseListener implements MouseMotionListener {
JLabel jl;
int imageX, imageY;
public DragMouseListener(JLabel jlabel) {
this.jl = jlabel;
jl.addMouseMotionListener(this);
}
#Override
public void mouseDragged(MouseEvent e) {
updateImagePosition(e);
}
#Override
public void mouseMoved(MouseEvent e) {
}
private void updateImagePosition(MouseEvent e) {
imageX = e.getX();
imageY = e.getY();
jl.setLocation(imageX, imageY);
}
}
Until now I am unable to even come close to a way of implementing it and I cannot find any references of the issue in the Internet. Any help (even rough ideas) would be much appreciated. Thanks in advance.
Nick

I tried what you asked for DragMouseListener but found it very uncomfortable so used JInternal Frame it works fine(but you can still drag images inside JInternal Frame,as I implemented what you asked for).Insted of hand free writing,I used JEditorPane(you can add hand written thing if you want,but it will be a mess) with accessible parent JScrollPane so that you can type how much you want.
You can drag JInternal Frame easily:
Note: I have used NetBeans GUI Builder for this and suggest you too to use any GUI builder as it makes
typing work easy.

There is no problem with your code. It is perfectly working fine. JDialog dialog = new JDialog(); dialog.getContentPane().add(new GamePane(10, 10)); dialog.pack(); dialog.setVisible(true); And i got the below.
