how to get the components at runtime

[kiran]

i hava some JTextFields and JLables in a class that extends JPanel. now if
i want to set the font property of all of them with minimul coading what
should i do? i know that i can set it by using the method setFont(Font f)
but i do not want to write this code for all my components. i would like
to use a loop to finish it. how do i do that??

I wouldn't use a loop, I'd just use a class that extends JTextField (for
example) and includes "setFont(...)" in its constructor, then create objects
of this class to add to the panel. I'm assuming that you want them all to
use the same font.

Kiran,

The fact that all of these GUI classes extend the Component class makes
this very easy to do. First, create an array of Components (the function
getComponents() returns just such an array (however, if you have components
that hold other components, like Panels, you'll have to do this for each
of them)). Second, simply use the following for loop (assuming that you
have the Component array which we will call comps[]):

for(int i = 0; i < comps.length; i++)
{
comps[i].setFont(Font f);
}

The function setFont() is in the Component class. However, even if each
of your components had a different setFont() method (ie. if you have to override
the Component setFont() method), this code would still work.

Three cheers for Object Oriented Programming!
