java, swing, Gridlayout problem
- by josh
I have a panel with GridLayout
But when I'm trying to run the program, only the first button out of 100 is shown.
Futhermore, the rest appear only when I move the cursor over them.
What's wrong with it?
Here's the whole class(Life.CELLS=10 and CellButton is a class which extends JButton)
public class MainLayout extends JFrame {
public MainLayout() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(650, 750);
setLayout(new FlowLayout());
//setResizable(false);
final JPanel gridPanel = new JPanel(new GridLayout(Life.CELLS, Life.CELLS));
for (int i=0; i<Life.CELLS; i++) {
for (int j=0; j<Life.CELLS; j++) {
CellButton jb = new CellButton(i, j);
jb.setPreferredSize(new Dimension(jb.getIcon().getIconHeight(), jb.getIcon().getIconWidth()));
buttons[i][j] = jb;
grid[i][j] = false;
gridPanel.add(jb);
}
}
add(gridPanel);
}
}
This is code of CellButton
package classes;
import javax.swing.JButton;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class CellButton extends JButton {
private int x;
private int y;
boolean alive;
ImageIcon icon;
boolean next;
// icons for grids
final ImageIcon dead =
new ImageIcon(JFrame.class.getResource("/images/image1.gif"));
final ImageIcon live =
new ImageIcon(JFrame.class.getResource("/images/image2.gif"));
public CellButton(int X, int Y) {
super();
x = X;
y = Y;
alive = false;
icon = dead;
setIcon(icon);
}
public int getX() {
return x;
}
public int getY() {
return y;
}
public boolean isAlive() {
return alive;
}
public void relive() {
alive = true;
icon = live;
setIcon(icon);
}
public void die() {
alive = false;
icon = dead;
setIcon(icon);
}
public void setNext(boolean n) {
next = n;
}
public boolean getNext() {
return next;
}
public ImageIcon getIcon() {
return icon;
}
}
