The Basics
The main FlowframTk window is shown in Figure 4.1.

FlowframTk uses a multiple-document interface (MDI). This means that you can have multiple images loaded in separate child windows, without having to start up new instances of FlowframTk. Most of the buttons and menu items will only be applied to the child window that currently has the focus. If there are no child windows, or if they have all been minimized, then the relevant buttons and menu items will be disabled. The only exceptions are the non-canvas specific items.
