How does that have to do with an "About myApplication" menu item  
*grin*? The good news though: getting this menu item is easy enough:  
you simply need to add a menu item titled "About <whatever>" into one  
of your menus. As long as it starts with "About", Qt will recognize it  
and move it into the Application menu for you. See the QMenuBar  
documentation (http://doc.trolltech.com/4.5/qmenubar.html#details)  
specifically the section titled "QMenuBar on Mac OS X". Typically I  
would add this menu item to a Help menu, as that would make sense on  
other platforms as well. Of course, you will still be responsible for  
making something happen when that menu item is selected, but Qt can  
make this easy as well: see http://doc.trolltech.com/4.5/qmessagebox.html#about 
  . Although personally, I prefer to make the about dialog myself so I  
can have a bit more control over its appearance.
