TKD AddProtocolCommand example

[DaveG via Digitalmars-d-learn]

Hopefully better formatting of code here:

import tkd.tkdapplication;

class Application : TkdApplication
{

     private void exitCommand(CommandArgs args)
     {
          this.exit();
     }

     private void saveMeCommand(CommandArgs args)
     {
         new MessageDialog(this.mainWindow,"Saving...")
             .setMessage("Bye")
             .show();
     }

     override protected void initInterface()
     {
         
this.mainWindow.addProtocolCommand(WindowProtocol.saveYourself, 
&this.saveMeCommand);

         auto frame = new Frame(2, ReliefStyle.groove)
              .pack(10);

         auto label = new Label(frame, "Hello World!")
             .pack(10);

         auto exitButton = new Button(frame, "Exit")
             .setCommand(&this.exitCommand)
             .underlineChar(1)
             .pack(10);
     }

}

void main(string[] args)
{
     auto app = new Application();
     app.run();
}
