Used to indicate which fields of a gdk-geometry structure should be paid attention to. Also, the presence/absence of :pos, :user-pos, and :user-size is significant, though they do not directly refer to gdk-geometry fields. :user-pos will be set automatically by gtk-window if you call the function gtk-window-move. :user-pos and :user-size should be set if the user specified a size/position using a - geometry command-line argument; the function gtk-window-parse-geometry automatically sets these flags.

:pos

Indicates that the program has positioned the window.

:min-size

Min size fields are set.

:max-size

Max size fields are set.

:base-size

Base size fields are set.

:aspect

Aspect ratio fields are set.

:resize-inc

Resize increment fields are set.

:win-gravity

Window gravity field is set.

:user-pos

Indicates that the window's position was explicitly set by the user.

:user-size

Indicates that the window's size was explicitly set by the user.
