NAME

       XmGetVisibility — A function that determines if a widget is visible "XmGetVisibility"

SYNOPSIS

       #include <Xm/Xm.h>
       XmVisibility XmGetVisibility(
       Widget widget);

DESCRIPTION

       XmGetVisibility returns the visibility state of the specified widget.  It checks to see if
       some part of the widget's rectangular area is unobscured by  the  widget's  ancestors,  or
       some part of the widget's rectangular area is inside the work window (but possibly outside
       the clip window) of a ScrolledWindow whose XmNscrollingPolicy  is  XmAUTOMATIC  and  whose
       XmNtraverseObscuredCallback is not NULL.

       XmGetVisibility does not check to see if widget is obscured by its siblings or by siblings
       of  its  ancestors.  Consequently,  XmGetVisibility  returns  XmVISIBILITY_UNOBSCURED  for
       widgets which are completely or partially covered by one or more siblings of widget by one
       or more siblings of ancestors of widget.

       When a widget which is unrealized is being queried, it is indicated  that  the  widget  is
       fully  obscured.   If  an  application  unmaps  a widget that has its XmNmappedWhenManaged
       resource set to True, the return value is undefined.  When a widget which is unmanaged  is
       being queried, it is indicated that the widget is fully obscured.

       widget    Specifies the ID of the widget

RETURN

       Returns one of the following values:

       XmVISIBILITY_UNOBSCURED
                 Indicates  that the widget is mapped, not obscured, and is completely visible on
                 the screen.

       XmVISIBILITY_PARTIALLY_OBSCURED
                 Indicates that the widget is mapped, and is not completely visible on the screen
                 (partially obscured).

       XmVISIBILITY_FULLY_OBSCURED
                 Indicates that the widget is not at all visible on the screen.
