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 \fBXmNscrollingPolicy\fP is \fBXmAUTOMATIC\fP and whose \fBXmNtraverseObscuredCallback\fP is not NULL\&. .PP \fBXmGetVisibility\fP does not check to see if \fIwidget\fP is obscured by its siblings or by siblings of its ancestors\&. Consequently, \fBXmGetVisibility\fP returns \fBXmVISIBILITY_UNOBSCURED\fP for widgets which are completely or partially covered by one or more siblings of \fIwidget\fP by one or more siblings of ancestors of \fIwidget\fP\&. .PP When a widget which is unrealized is being queried, it is indicated that the widget is fully obscured\&. If an application unmaps a \fIwidget\fP that has its \fBXmNmappedWhenManaged\fP 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\&. .IP "\fIwidget\fP" 10 Specifies the ID of the widget .SH "RETURN" .PP Returns one of the following values: .IP "\fBXmVISIBILITY_UNOBSCURED\fP" 10 Indicates that the widget is mapped, not obscured, and is completely visible on the screen\&. .IP "\fBXmVISIBILITY_PARTIALLY_OBSCURED\fP" 10 Indicates that the widget is mapped, and is not completely visible on the screen (partially obscured)\&. .IP "\fBXmVISIBILITY_FULLY_OBSCURED\fP" 10 Indicates that the widget is not at all visible on the screen\&. .SH "RELATED" .PP \fBXmIsTraversable\fP(3), \fBXmManager\fP(3), and \fBXmProcessTraversal\fP(3)\&. .\" created by instant / docbook-to-man, Sun 22 Dec 1996, 20:24
