Dialog

subclass of Toplevel
Dialog produces "intelligent" dialog. They have a simple option to make them resizable or not. They automatically assume a reasonable minimum size based on their content (The dialog will be placed on the screen and its size calculated at the first idle moment after dialog creation. The dialog will place itself so that the mouse pointer is is positioned over it, without being placed partly out of the screen. If it is resized, it remembers its size for the next display.

By default, the dialog has a "Close" button that destroys the dialog on invocation. Other buttons can be added easily using the add method. Invoking a command by clicking on a button (or using a key shortcut) will close the dialog, unless the button is persistent, or was invoked using the Adjust mouse button. The dialog has one component named options, which is a frame in which optionmenus, entries, etc. can be placed.
