the InternalFrameIconifyListener class, presented earlier in Listing 8-5, to listen for internal
frames being iconified and deiconified.
Figure 8-6 shows how the program looks when it first starts. One particular internal frame
has been designated a palette, and the outline drag mode is enabled.
The complete source for the example is shown in Listing 8-6.
