The parent argument can be #f or an existing frame. Under Windows, if parent is an existing frame, the new dialog is always on top of its parent. Under Windows and X, a dialog is iconized when its parent is iconized.
If parent is #f, then the eventspace for the new dialog is the current eventspace, as determined by current-eventspace. Otherwise, parent’s eventspace is the new dialog’s eventspace.
If the width or height argument is not #f, it specifies an initial size for the dialog (in pixels) assuming that it is larger than the minimum size, otherwise the minimum size is used. Under Windows and Mac OS X (and with some X window managers) dialogs are not resizeable.
If the x or y argument is not #f, it specifies an initial location for the dialog. Otherwise, if no location is set before the dialog is shown, it is centered (with respect parent if not #f, the screen otherwise).
The style flags adjust the appearance of the dialog on some platforms:
'no-caption – omits the title bar for the dialog (Windows)
'resize-border – adds a resizeable border around the window (Windows) or grow box in the bottom right corner (Mac OS X)
'no-sheet – uses a movable window for the dialog, even if a parent window is provided (Mac OS X)
Even if the dialog is not shown, a few notification events may be queued for the dialog on creation. Consequently, the new dialog’s resources (e.g., memory) cannot be reclaimed until some events are handled, or the dialog’s eventspace is shut down.
For information about the enabled argument, see window<%>. For information about the border, spacing, and alignment arguments, see area-container<%>. For information about the min-width, min-height, stretchable-width, and stretchable-height arguments, see area<%>.
