hi,
how can i change the size of JButton ( i want the size of JButton to be 25X25)...
i used setPreferredSize(Dimension d) method but it didn't work with me??!!

Will work unless you have a layout manager that overrides manual changes, and there may be other reasons, but of course I can not say for sure because you give no example of your code.

Sorry for bringing this thread back from the dead but I had a question regarding the topic.

setPreferredSize will work but JButtons, but not if I have a setLayout(GridLayout) right?

Nope, the gridlayout gives all components inside it the same width / height.

A boxLayout puts all components in a SINGLE row or column without affecting them. (BoxLayout)
Now because it's much likely you want multiple rows or columns i suggest you try to put panels in a gridLayout and the panels set up with a boxLayout
Like this if you know what i mean:

-------------GRIDLAYOUT--------------
|   B   |   B     |   B    |   B   |
|   O   |   O     |   O    |   O   |
|   X   |   X     |   X    |   X   |
|       |         |        |       |
|       |         |        |       |

Nvm I found out, John was right, this worked:

ButtName.setPreferredSize(new Dimension(buttonWidth, buttonHeight));

I'm also having this problem. I used this code:

ButtName.setPreferredSize(new Dimension(buttonWidth, buttonHeight));

but I'm getting this error:

cannot find symbol
symbol  : class Dimension

How do I declare or instantiate "Dimension"?

Thanks!

Try to import

java.awt.Dimension;
OR
java.awt.*;

[organizedchaos]

wow! That worked! Thanks!
