This question is related to my previous question http://stackoverflow.com/questions/2376027/how-to-generate-cartesian-coordinate-x-y-from-gridbaglayout
I have successfully get the coordinate of each pictures, however when I checked the coordinate through (System.out.println) and the placement of the images on the screen, it seems to be wrong. e.g. if on the screen it was obvious that the x point of the first picture is on cell 2 which is on coordinate of 20, but the program shows x=1.
Here is part of the code:
public Grid (){
setPreferredSize(new Dimension(600,600));
....
setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
gc.weightx = 1d;
gc.weighty = 1d;
gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right
gc.fill = GridBagConstraints.BOTH;
JLabel[][] label = new JLabel[ROWS][COLS];
Random rand = new Random();
// fill the panel with labels
for (int i=0;i<IMAGES;i++){
ImageIcon icon = createImageIcon("myPics.jpg");
int r, c;
do{
//pick random cell which is empty
r = (int)Math.floor(Math.random() * ROWS);
c = (int)Math.floor(Math.random() * COLS);
} while (label[r][c]!=null);
//randomly scale the images
int x = rand.nextInt(50)+30;
int y = rand.nextInt(50)+30;
Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH);
icon.setImage(image);
JLabel lbl = new JLabel(icon); // Instantiate GUI components
gc.gridx = r;
gc.gridy = c;
add(lbl, gc); //add(component, constraintObj);
label[r][c] = lbl;
}
I checked the coordinate through this code:
Component[] components = getComponents();
for (Component component : components) {
System.out.println(component.getBounds());
}
