Arguments: window
Returns true if the argument has been modified since the most recent time it was saved to a file. This function is typically used to determine whether an object needs to be saved.
Whether an object has been modified depends on the type of object. A
text-edit-pane
has been modified if the text has been changed. A form
if any control on the form has
been changed (resized, moved, or with different property values). A
project is modified if any modules, libraries, subprojects, or files
have been added or deleted or themselves changed, or the properties of
the project have been changed, or the associated .lpr file has been
changed. A grid-widget
is modified if its delay-write-cell-value property is true and it
has any pending user edits. An object-editor
is modified if there are any
unsaved edits to its currently-displayed instance.
An application could call (setf modified) on a text-edit-pane
(or rich-edit-pane
) with a value of nil
to declare that the window's contents do not
currently need to be saved. This would typically be useful
immediately after programmatically placing some initial text into the
control for the end user to modify. On the other hand, it is
generally unnecessary for an application to set the value to true
because this is done internally whenever the content changes.
