Note "Information"
EasyStatusMenu is a subclass to quickly create a statusmenu. It creates a capture of the menubar where the menu will reside and uses that to draw an almost transaperent but clickable background. Use the normal method for updating the NSMenuMBS property or just pass a reference to the construcor. Pass a black and white image with a mask for best results, you can also pass false in the constructor to use the black areas of the image as a mask. An alternateImage(clicked state) will be created for you, but you can also set your own after the constructor. If the image is taller than MenuBarHeightMBS it will be scaled down to fit. call it like this... myStatusItem=new EasyStatusItem(image,NSMenuMBS,hasMask) ...and store the result in a persistant variable.
