Class MainFrame

java.lang.Object

se.lth.control.MainFrame

public class MainFrame
extends java.lang.Object

MainFrame contains a static convenience method to handle the initialization of a Swing based application. Assuming the main panel of the application is a JPanel subclass, MyPanel, the main class for the application would reduce to

 public class MyApplication
 public static main(String[] args) {
   MainFrame.setFrame(new MyPanel(), "MyApplication");
 }  
 

There is also a static method to display a frame containing the text "Loading, please wait...". It may be used when the loading and initialization of the main panel takes some time, so that the user is kept reasonably happy. The main program in that case would be

 public class MyApplication
 public static main(String[] args) {
   MainFrame.showLoading();
   MainFrame.setFrame(new MyPanel(), "MyApplication");
 }  
 

Note that the instantiation of MyPanel should not take place until after the return of MainFrame.showLoading() so that the "Loading ... " frame is displayed before the instantiation starts.
