Description
The class of frame managers.
Frame managers control the realization of the look and feel of a frame. The frame manager interprets the specification of the application frame in the context of the available window system facilities, taking into account preferences expressed by the user.
In addition, the frame manager takes care of attaching the pane hierarchy of an application frame to an appropriate place in a window hierarchy.
Thus, the frame manager decides the following:
- What concrete gadget to create for an abstract gadget.
- How to layout the various parts of a frame, such as its menu, tool, and status bars.
- How to lay out dialogs and their exit buttons.
- How much spacing to use in various conventional layouts.
In addition, a frame manager maps dialog functions such as choose-file to their appropriate native dialogs.
