A one dimensional shape.
public abstract class LineShapeBase : ShapeBase, ILinearShape |
Description
Base class for most of the linear shapes in the standard libraries and custom libraries.
LinearShapeBase can but need not be used as a base class for custom linear shapes. It provides support for the following areas:
• | Line caps management |
• | Vertex and control point management |
Name |
Description |
---|---|
IsDirected |
Indicates wether one of the line ends has a line cap. |
MaxVertexCount |
Returns the maximum number of vertices for this shape. |
MinVertexCount |
Returns the Minimum number of vertices for this shape. |
VertexCount |
Returns the current number of vertices of this shape. |
Name |
Description |
---|---|
AddVertex |
Adds a new vertex at the indicated position. |
CalcNormalVector |
Calculates a vector perpendicular to the shape's outline. |
CalculateConnectionFoot |
Calculates the foot of a connection. |
CopyFrom |
Copies as many properties as possible from the source shape. |
GetControlPointIds |
Returns a list of ControlPointIds that fulfill at least one of the requested ControlPointCapabilities. |
GetControlPointPosition |
Returns the position of the indicated control point. |
GetMenuItemDefs |
Retrieves the list of context menu item definitions of the shape. |
GetNextVertexId |
Returns the ControlPointId of the vertex next to the indicated vertex. Direction: ControlPointId.FirstVertex to ControlPointId.LastVertex |
GetPreviousVertexId |
Returns the ControlPointId of the vertex next to the indicated vertex. Direction: ControlPointId.LastVertex to ControlPointId.FirstVertex. |
GetPropertyDefinitions |
Implementation of the IEntity.GetPropertyDefinitions pseudo member. |
HasControlPointCapability |
Tests, whether a control point has at least one of a set of given capabilities. |
InsertVertex |
Inserts a new vertex at the indicated position before the indicated vertex. |
Invalidate |
Invalidates the shape. |
MakePreview |
Transforms the shape into a preview shape. |
NotifyStyleChanged |
Notifies the shape that the given style has changed. |
RemoveVertex |
Removes the indicated vertex. |
Name |
Description |
---|---|
ControlPointCount |
Returns the number of control points. |
EndCapAngle |
Returns the angle in degrees of the line's end point line cap. |
EndCapBounds |
Returns the Bounds of the line's end point line cap. |
EndCapStyleInternal |
Returns the ICapStyle of the line's end point line cap. |
StartCapAngle |
Returns the angle in degrees of the line's start point line cap. |
StartCapBounds |
Returns the Bounds of the line's start point line cap. |
StartCapStyleInternal |
Returns the ICapStyle of the line's start point line cap. |
pointIds |
List of ControlPointIds for mapping a vertex' index to its ControlPointId. |
shapePoints |
Array of points used for drawing |
vertices |
List of vertices (absolute coordinates) |
Name |
Description |
---|---|
CalcCapAngle |
Calculates the angle of the a cap in degrees. |
CalculateBoundingRectangle |
Calculates the axis aligned bounding rectangle of the shape and its children. |
Constructor |
Constructs a new shape instance. |
ContainsPointCore |
Base implementation of ContainsPoint testing wether one the line caps contains the given point. |
DrawEndCapBackground |
Fills the background of the line cap. |
DrawStartCapBackground |
Fills the background of the line cap. |
EndCapContainsPoint |
Tests wether the line cap contains the given point. |
EndCapIntersectsWith |
Tests wether the line cap intersects with the given rectangle. |
GetControlPointId |
Returns the ControlPointId for the indicated vertex. |
GetControlPointIndex |
Returns the index of the indicated vertex. |
GluePointNeighbourMoved |
Notifies the shape that a point next to a glue point has moved. If the glue point is connected to a shape's Reference point, the position of the glue point has to be adjusted. |
InitializeToDefault |
Initializes this shape with default values. |
InvalidateDrawCache |
Clears all objects and buffers needed for drawing the shape so that they will be recalculated the next time. |
IsConnectionPointEnabled |
Checks if the given ControlPoint is a mapped ConnectionPoint (if this shape has a model object). |
IsFirstVertex |
Tests wether the indicated control point is the first vertex. |
IsLastVertex |
Tests wether the indicated control point is the last vertex. |
LoadFieldsCore |
Implementation of IEntity.LoadFields. |
LoadInnerObjectsCore |
Implementation of IEntity.LoadInnerObjects. |
MoveByCore |
Implementation of Shape.MoveBy. |
ProcessExecModelPropertyChange |
Implementation of reacting to model property changes |
RecalcDrawCache |
Recalculates all objects and buffers needed to draw this shape. |
RotateCore |
Implementation of Shape.Rotate. |
SaveFieldsCore |
Implementation of IEntity.SaveFields. |
SaveInnerObjectsCore |
Implementation of IEntity.SaveInnerObjects. |
StartCapContainsPoint |
Tests wether the line cap contains the given point. |
StartCapIntersectsWith |
Tests wether the line cap intersects with the given rectangle. |
TransformDrawCache |
Transforms all objects and buffers to the current position and angle. |
UpdateDrawCache |
Checks if any objects and buffers needed to draw the shape are invalid and calls RecalcDrawCache in this case. |
