Actionlistener and actionperformed question
i have created a matrix with button and i want to listen event of this matrix. i need to take coordinates of matrix (X Y) when a button clicked and i ll use this coordinate for my other operations in code but i couldnt find a solution get coordinates
this is snippet of my code
private void BlockButtonSec() {
secim=1;
for (int i = 0; i < 50; i++) {
for (int j = 0; j < 50; j++) {
butonlar[i][j].addActionListener(this);
}
}
for (int i = 0; i < 50; i++) {
for (int j = 0; j < 50; j++) {
gecici=butonlar[i][j];
gecici.addActionListener
(new ActionListener() {
public void actionPerformed(ActionEvent event) {
coordinate_x=i;
coordinate_x=j;
sent(coordinate_x,coordinate_y);
setbackgroundofthisbutton();
}
});
}
}
and other my idea is taking out actionperformed side like that:
public void actionPerformed(ActionEvent e) {
// JButton tiklandi=new JButton();
if(secim==1){
butonlar[i][j].se
// tiklandi.setBackground(Color.RED);
}
}
this code is not completed --> butonlar[i][j].se because i,j is not available but i couldnt sent i,j
just i need an idea that:
when i clicked a button how can i change any button color in buttons of matrix and how can i get coordinates from buttons of matrix

One way would be to use the ClientProperties of the JComponent class. The ClientProperties is a hashtable.
You could create an object with the x,y for the button and save/put it in the ClientProperties for that button. When the listener method is called you could then get the object with the values from the ClientProperties for the button that was pressed.
