Using a method to change a buttons color

Thread view:

Hi,

I have a series of buttons name

btnPXxY where X and Y are numbers ranging from 0 to 10 in a grid of
buttons. For example, a button name btnP0x0 and another named btnP0x1
etc.

When the buttons are pressed I want to pass integers x and y to a
method. This method is going to a bunch of things with these numbers
but one thing i would like to do would be to change the color of the
button corresponding to this.

How can I pass the variables x and y into another variable name? is
this possible? something along the lines of:

btnP + varX + x + varY. bgcolor = red.

Thanks for any suggestions. I am HOPING that I do not have to pass
the button object into the function since I will have to change a
bunch of code for these buttons.

Thanks.

Why not create a 10x10 array to hold the pointers to the buttons? The
Object that btnArray[0][1] would point to would be the button at that
grid location.

Each button can be its own listener and change its own color by waiting
for the Action Event to be generated when a user clicks it. By doing it
that way you don't need to know what the x and y values are. Each button
changes itself and would implicitly know what to change.

I personally don't understand what the above line is supposed to do.
