The default window type, describing a toplevel window with a title bar,
minimize, maximize and
close buttons. Note that these window decorations
are provided by the window manager and may vary in appearance or even
not exist on some operating systems.
1
GTK_WINDOW_DIALOG
A window type that is intended for messages requiring a user response.
If a maximize button is displayed, it is greyed
out and the maximize function disabled on a dialog window.
2
GTK_WINDOW_POPUP
A window type with no window decorations or associated functions.
Do not use this to create popup menus; refer instead to the
popup() method in
GtkMenu, which provides its own internal
popup window.
