...toolboxes.
This three-layer view of the toolbox breaks down under close scrutiny, because the windowing, drawing, and editor toolboxes are actually interdependent and intertwined. Nevertheless, the layered separation is a good approximation.

...class:
To run the example, type it into DrScheme's top window and click the Execute button. (The current language in DrScheme should be MrEd Debug.) Alternatively, save the program to a file using your favorite text editor, and then load it into MrEd via the Load File menu item.

For a panel, the graphical representation is merely an optional border.

...HREF="node19.htm">area<%>.
Some of the types in Figure 2.2 are represented by interfaces, and some types are represented by classes. In principle, every area type should be represented by an interface, but whenever the windowing toolbox provides a concrete implementation, the corresponding interface is omitted from the toolbox.

Disabling a window prevents mouse and keyboard events from reaching the window, but other kinds of events, such as update events, are still delivered.

...Windows.
Alt-Space invokes the system menu under Windows, but this shortcut is implemented by on-system-menu-char, which is called by on-subwindow-char in frame% and on-subwindow-char in dialog%.

...style.
This is analogous to multi-level styles, like the paragraph and character styles in FrameMaker. In this analogy, the paragraph style is the base style, and the character style is the shift style. However, FrameMaker allows only those two levels; with join styles support any number of levels.

However, the exit handler is not changed, so evaluating (exit) does exit MrEd unless the exit handler is changed before calling graphical-read-eval-print-loop.
