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 ( cadex.UTF16String theName )

inline

Constructor.

Creates a named object, if theName is not empty.

Member Function Documentation

Accept()

void cadex.Drawing.Layer.Accept ( cadex.Drawing.ElementVisitor theVisitor )

inline

Accepts the element visitor.

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

Add()

void cadex.Drawing.Layer.Add ( cadex.Drawing.Element theElement )

inline

Adds element to the drawing layer.

Remove(), Contain().

Dispose()

override void cadex.Drawing.Layer.Dispose ( bool disposing )

inlineprotectedvirtual

Reimplemented from cadex.BaseObject.

IsVisible()

bool cadex.Drawing.Layer.IsVisible ( )

inline

Returns true if the drawing layer is visible.

Returns false if the drawing layer IsNull().

Remove()

bool cadex.Drawing.Layer.Remove ( cadex.Drawing.Element theElement )

inline

Removes element from the drawing layer.

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