Detailed Description

Provides logical grouping of Element objects.

Layers are commonly used to group objects in the drawing by function (e.g. walls, furniture, etc.), but in principle they can represent any type of virtual grouping. All objects in a layer share appearance, can be shown and hidden together. A drawing element can only belong to one layer.

The drawing layer holds an IsVisible() attribute, which is true by default.

Constructor & Destructor Documentation

◆ Layer() [1/2]

cadex::Drawing::Layer::Layer ( )

inline

Constructor.

Creates not initialized object, for which IsNull() returns true.

◆ Layer() [2/2]

cadex::Drawing::Layer::Layer ( const UTF16String & theName )

explicit

Constructor.

Creates a named object, if theName is not empty.

Member Function Documentation

◆ Accept()

void cadex::Drawing::Layer::Accept ( ElementVisitor & theVisitor ) const

Accepts the element visitor.

Calls overloaded operator() of theVisitor for each element in drawing layer.

◆ Add()

void cadex::Drawing::Layer::Add ( const Element & theElement )

Adds element to the drawing layer.

See also: Remove(), Contain().

◆ IsVisible()

bool cadex::Drawing::Layer::IsVisible ( ) const

Returns true if the drawing layer is visible.

Returns false if the drawing layer IsNull().

◆ Remove()

bool cadex::Drawing::Layer::Remove ( const Element & theElement )

Removes element from the drawing layer.

Returns true if the element has been in the list and false otherwise.
