XtQueryGeometry


NAME

XtQueryGeometry - query the preferred geometry of a child widget

SYNTAX

XtGeometryResult XtQueryGeometry(w, intended, pre- ferred_return) Widget w; XtWidgetGeometry *intended, *preferred_return;

ARGUMENTS

intended Specifies any changes the parent plans to make to the child's geometry or NULL. preferred_return Returns the child widget's preferred geometry. w Specifies the widget.

DESCRIPTION

To discover a child's preferred geometry, the child's par- ent sets any changes that it intends to make to the child's geometry in the corresponding fields of the intended structure, sets the corresponding bits in intended.request_mode, and calls XtQueryGeometry. XtQueryGeometry clears all bits in the pre- ferred_return->request_mode and checks the query_geometry field of the specified widget's class record. If query_geometry is not NULL, XtQueryGeometry calls the query_geometry procedure and passes as arguments the spec- ified widget, intended, and preferred_return structures. If the intended argument is NULL, XtQueryGeometry replaces it with a pointer to an XtWidgetGeometry structure with request_mode=0 before calling query_geometry.
