A lot of buttons

[Bart]

Hi,

I'm trying to learn java programming for school. Now I have to make a
calculator. But I have to make a lot of buttons for it. Is there a way to
make a methode for makeing a button that I only have to type (for example)
makeButton(one);.
And that the button will be created.

Already thanks, Bart

Thanks for you reaction.

But I do not realy understand the answer. Could you please explain your
code?

Thanks, Bart

If you want a pretty button, you need to get something like Photoshop
to create gifs, ideally one for pressed, unpressed, selected etc etc.

If you just want method to create a simple text button try something
like this untested code:

static public JButton makeButton( String label )
{
Jbutton b = new JButton( label );
b.setForeground( Color.white );
b.setBackground( new Color ( 0x228b22 ) );
b.setFont( new Font( "Dialog", Font.BOLD, 12 ));
return b;
}

This method call simply creates a button with the label you pass in as
the parameter, and an actionlistener (which you will have to code and is
not shown here) and returns a reference to that button so you can put it
on your form.
