Hi, all expert

I am stuck in changing the cell size of
JButton[] abc = new JButton[49];
which is added in JPanel midPanel = new JPanel(new GridLayout(7,7))

Is there a way to change the size JButton ?
The each cell size of JButton seems to be determined by some default value.
Thank you.

Daniel

if it doesn't work, try with setMinimumSize(btnDim);

You might be better off changing the panel size. The buttons will simply fill it equally to the maximum extent

> The each cell size of JButton seems to be determined by some default value.

the space available is divided equally between each cell.
You can decrease the amount of space taken up by each button by adding a border to the button

button.setBorder(BroderFactory.createEmptyBorder(10, 10, 10, 10));

if you want control over the size of individual buttons then you may need to use a different layout manager as GridLayout sizes each cell equally
