array of buttons

[aymane chetibi]

hi all,

I have an application in which the number of buttons to display is known at run time.
I store them in an array of buttons.

How can I handle the actions of these buttons, and know which one has issued which action so that I know what to do next.

Please help me with that, and if you think the array solution is wrong please give me suggestions.

Thanks a lot.

How can I handle the actions of these button ?

add ActionListeners to them. When a button is clicked, the code
in youre action listener will be ran.

and know which one has issued which action so that I know what to do next?

That should be handled in the Model component of your class. Are you familiar with the basics of MVC ?

I know MVC, can you just tell me what is the code I should put to listen to the action of those buttons ?
and then how to know wgicg one it is:
if( (JButton)e.getSource().getText == "blabla")

something like that .

thanks

you could use
button.getActionCommand()

if you don't use setActionCommand(..), it defaults to the button's text.

I think I am not explaining well what the problem is.

the problem is again how to listen for the action of those buttons, and once we get an action how to determine which button is it.
maybe your last reply answers the second question but where can I check this value ?

in a simple case (not that you'd actually do it this way),
consider the buttons on a calculator

if(button.getActionCommand().equals("1"))//id's the button displaying the "1"

thanks a lot I figured that out.

thanks again.

Typically, I wouldn't use action commands for that. Instead I would register a new listener to each button, so that each listener knows which button it is responsible for.
