Arguments: system
Returns the development-main-window of
system. The current system is the value of
*system*.
When the IDE is present, development-main-window returns the invisible window that serves as the owner of all IDE windows. (This owner window allows the multiple top-level IDE windows to bury, expose, shrink and expand together as a single application.) In a standalone CG application, or in a development lisp that includes CG but not the IDE, development-main-window returns the screen.
The owner argument to the function make-window defaults to the value returned by development-main-window. This means that the default owner of a window created in the IDE will be the IDE owner window, so that the window will exist "within the IDE" for convenience. Otherwise the default owner of a window is the screen.
development-main-window is a
property of the system class.
