Tues Feb 3: first GUI application with a button! #2

Just like we did yesterday, we are going to add a button to our program. It seems simple enough that all we would need to do is to add this line of code


b = new Button("Zoinks!"); //declare button

f1.add(b); //add button to frame


just above this line of code


f1.show( );



but unfortunately its not that simple. To put any sort of compoent on an application GUI, you have to use a LAYOUT MANAGER. The simplest kind is a "Flow Layout"; this is what you would type:



f1.setLayout(new FlowLayout());



and you should write inside the constructor area, preferably ABOVE where you typed in the code for adding a Button



OK, let's put all this together, and see what we get!


cheers,

Uncle Paulie
