Changing the size of a container.
Hiya Guys,
I am trying to change the size of a applet container so that when it executes it shows all numbers and button text. When this class is run, the container shows the text on the buttons as three dots. I was wondering if anyone knew how to make the container bigger so that my text would show. Here is my code: -
