32.     --  This widget is the base of the tree for displayable objects.

33.     --  (A displayable object is one which takes up some amount

34.     --  of screen real estate). It provides a common base and interface

35.     --  which actual widgets must adhere to.

36.     --

37.     --  This package provides some services which might have been more appropriate

38.     --  in some other packages, but could not because of dependency circularities

39.     --  (there are for instance some functions relating to colors and colormaps).

40.     --  We have tried to reference these functions in the other packages as well.

1265.        --  states a widget can be in.

1266.        --

1267.        --  - "Toplevel":

1269.        --    mostly true for windows and dialogs.

1270.        --

1271.        --  - "No_Window":

1272.        --    Set if the widget does not have an associated X11 window, ie can not

1273.        --    receive events directly. For instance, a Gtk_Toolbar does not have

1274.        --    an associated window. These objects are more lightweight, but require

1275.        --    more work from GtkAda. This flag is only set if the widget will never

1276.        --    have a window, even after it is realized.

1277.        --

1278.        --  - "Realized":

1279.        --    Set if the widget has been realized, ie its associated X11 window has

1280.        --    been created (providing the widget excepts a window, see the No_Window

1281.        --    flag

1282.        --

1290.        --

1292.        --    Set if the widget is listening to events. See the function

1294.        --    have a different visual aspect to clue that it is unavailable (for

1295.        --    instance an insensitive item menu will be grayed)

1296.        --

1300.        --

1301.        --  - "Can_Focus":

1303.        --    widgets can not have the focus.

1304.        --

1305.        --  - "Has_Focus":

1308.        --

1309.        --  - "Can_Default":

1310.        --    Set if the widget can be the default widget in a window, ie the one

1311.        --    that will get the keyboard events by default. For instance, the

1312.        --    default button in a dialog is the one that gets clicked on when the

1313.        --    user pressed Enter anywhere in the dialog.

1314.        --

1321.        --    the application, even if it does not have the focus. There can be only

1322.        --    such widget per application at any given time.

1323.        --

1324.        --  - "Rc_Style":

1325.        --    Set if the widget's style is either the default style, or in a

1326.        --    customization file. This is unset if the style has been modified by

1327.        --    the user.

1328.        --

1329.        --  - "Composite_Child":

1330.        --    This indicates whether the widget is composed of other widgets

1331.        --

1332.        --  - "No_Reparent":

1333.        --    This flags is never used in gtk+.

1334.        --

1337.        --    unset when the container itself has some special drawing routines. It
