Hi I want to be able to change the name of the JFrame I am working on. It is currently named SwimmingPoolVolumeCalculator. When I go the Company Tab and enter in a name, I want that name to be shown as the new Title of the JFrame. How can i do this? Here is my code:
public class SwimmingPoolVolumeCalculator<exitHandler> extends JFrame
{

It should be as easy as
private void New_Name()
{
this.setTitle(newTitle.getText());
}
But that isn't working for me. Any help would truly be appreciated. Thanks!
