## development-main-window

Arguments: system

Returns the development-main-window of system. The current system is the value of `*system*`.

When the IDE is present, this function returns the main IDE window that is the owner of the various IDE tool windows. See main-ide-window and use-ide-parent-window. When the IDE is not present (either in a standalone Common Graphics application or in a development lisp that has loaded Common Graphics but not the IDE), this function 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 main-ide-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.
