AIS_AttributeFilter Class Reference

Selects Interactive Objects, which have the desired width or color.
The filter questions each Interactive Object in local
context to determine whether it has an non-null
owner, and if so, whether it has the required color
and width attributes. If the object returns true in each
case, it is kept. If not, it is rejected.
This filter is used only in an open local context.
In the Collector viewer, you can only locate
Interactive Objects, which answer positively to the
filters, which are in position when a local context is open.

 AIS_AttributeFilter ()
 Constructs an empty attribute filter object.
This filter object determines whether selectable
interactive objects have a non-null owner.

 AIS_AttributeFilter (const Quantity_NameOfColor aCol)
 Constructs an attribute filter object defined by the
color attribute aCol.

 AIS_AttributeFilter (const Standard_Real aWidth)
 Constructs an attribute filter object defined by the line
width attribute aWidth.

Standard_Boolean HasColor () const
 Indicates that the Interactive Object has the color
setting specified by the argument aCol at construction time.

Standard_Boolean HasWidth () const
 Indicates that the Interactive Object has the width
setting specified by the argument aWidth at
construction time.

void SetColor (const Quantity_NameOfColor aCol)
 Sets the color aCol.
This must be chosen from the list of colors in Quantity_NameOfColor.

void SetWidth (const Standard_Real aWidth)
 Sets the line width aWidth.

void UnsetColor ()
 Removes the setting for color from the filter.

void UnsetWidth ()
 Removes the setting for width from the filter.

virtual Standard_Boolean IsOk (const Handle< SelectMgr_EntityOwner > &anObj) const
 Indicates that the selected Interactive Object passes
the filter. The owner, anObj, can be either direct or
user. A direct owner is the corresponding
construction element, whereas a user is the
compound shape of which the entity forms a part.
If the Interactive Object returns Standard_True
when detected by the Local Context selector through
the mouse, the object is kept; if not, it is rejected.
