Panedwindow and Friends

PanedWindow, Radiobutton, Button, Label with graphic, labelFrame

PanedWindow is a really cool widget if just a little tricky to manage.  Raidobutton are nothing short of fun to use – I just wish there was a way to make the actual button graphic larger. At any rate, this example demonstrates a 3 paned window. In the left one we create a series of labels that “looks” like a list but isn’t – we use the ability of a lable ot hold both a graphic and text and pack them in a LableFrame.  On the right top we demo radio buttons and on the right bottom we have a couple of action buttons to do somethingl
