Open CASCADE Technology 6.6.0
|
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. |
