Syntax
public class PolyLineObject : ReportComponentBase, IFRSerializable
Remarks

Use the Border.Width, Border.Style and Border.Color properties to set the line width, style and color.

Constructors

PolyLineObject()

Initializes a new instance of the LineObject class with default settings.

Declaration
public PolyLineObject()

Fields

polygonSelectionMode

do not set this value, internal use only

Declaration
protected PolyLineObject.PolygonSelectionMode polygonSelectionMode
Field Value
Type Description
PolyLineObject.PolygonSelectionMode

Properties

CenterX

Returns origin of coordinates relative to the top left corner

Declaration
public float CenterX { get; set; }
Property Value
Type Description
System.Single

CenterY

Returns origin of coordinates relative to the top left corner

Declaration
public float CenterY { get; set; }
Property Value
Type Description
System.Single

Points

Return points collection. You can modify the collection for change this object.

Declaration
public PolyLineObject.PolyPointCollection Points { get; }
Property Value
Type Description
PolyLineObject.PolyPointCollection

PointsArray

Return points array of line deprecated

Declaration
[Obsolete]
public PointF[] PointsArray { get; }
Property Value
Type Description
PointF[]

PointTypesArray

Return point types array. 0 - Start of line, 1 - Keep on line deprecated

Declaration
[Obsolete]
public byte[] PointTypesArray { get; }
Property Value
Type Description
System.Byte[]

Methods

addPoint(Single, Single, Byte)

Add point to end of polyline, need to recalculate bounds after add First point must have zero coordinate and zero type. Recalculate bounds. Method is slow do not use this.

Declaration
protected PolyLineObject.PolyPoint addPoint(float localX, float localY, byte pointType)
Parameters
Type Name Description
System.Single localX

local x - relative to left-top point

System.Single localY

local y - relative to left-top point

System.Byte pointType

depreceted

Returns
Type Description
PolyLineObject.PolyPoint

Assign(Base)

Copies the contents of another, similar object.

Declaration
public override void Assign(Base source)
Parameters
Type Name Description
Base source

Source object to copy the contents from.

Overrides
ReportComponentBase.Assign(Base)
Remarks

Call Assign to copy the properties from another object of the same type. The standard form of a call to Assign is

destination.Assign(source);

which tells the destination object to copy the contents of the source object to itself. In this method, all child objects are ignored. If you want to copy child objects, use the AssignAll(Base) method.

See Also
AssignAll(Base)

deletePoint(Int32)

Delete point from polyline by index. Recalculate bounds. Method is slow do not use this.

Declaration
protected void deletePoint(int index)
Parameters
Type Name Description
System.Int32 index

Index of point in polyline

Deserialize(FRReader)

Declaration
public override void Deserialize(FRReader reader)
Parameters
Type Name Description
FRReader reader
Overrides
ReportComponentBase.Deserialize(FRReader)

Draw(FRPaintEventArgs)

Declaration
public override void Draw(FRPaintEventArgs e)
Parameters
Type Name Description
FRPaintEventArgs e
Overrides
ReportComponentBase.Draw(FRPaintEventArgs)

drawPoly(FRPaintEventArgs)

Draw polyline path to graphics

Declaration
protected virtual void drawPoly(FRPaintEventArgs e)
Parameters
Type Name Description
FRPaintEventArgs e

Event arguments

GetPath(Pen, Single, Single, Single, Single, Single, Single)

Calculate GraphicsPath for draw to page

Declaration
public GraphicsPath GetPath(Pen pen, float left, float top, float right, float bottom, float scaleX, float scaleY)
Parameters
Type Name Description
Pen pen

Pen for lines

System.Single left

Left boundary

System.Single top

Top boundary

System.Single right

Right boundary

System.Single bottom

Bottom boundary

System.Single scaleX

scale by width

System.Single scaleY

scale by height

Returns
Type Description
GraphicsPath

Always returns a non-empty path

insertPoint(Int32, Single, Single, Byte)

Insert point to desired place of polyline recalculateBounds(); Method is slow do not use this

Declaration
protected PolyLineObject.PolyPoint insertPoint(int index, float localX, float localY, byte pointType)
Parameters
Type Name Description
System.Int32 index

Index of place from zero to count

System.Single localX

local x - relative to left-top point

System.Single localY

local y - relative to left-top point

System.Byte pointType

deprecated

Returns
Type Description
PolyLineObject.PolyPoint

RecalculateBounds()

Recalculate position and size of element

Declaration
public void RecalculateBounds()

Serialize(FRWriter)

Serializes the object.

Declaration
public override void Serialize(FRWriter writer)
Parameters
Type Name Description
FRWriter writer

Writer object.

Overrides
ReportComponentBase.Serialize(FRWriter)
Remarks

Do not call this method directly. You should override it if you are developing a new component for FastReport.

This method is called when the object needs to save the state. It may happen when:

  • saving the report to the file or stream;
  • saving the report to the designer's undo buffer;
  • assigning the object to another object using the Assign(Base) or AssignAll(Base) methods;
  • saving the object to the designer's clipboard;
  • saving the object to the preview (when run a report).

SetPolyLine(PointF[])

Declaration
public void SetPolyLine(PointF[] newPoints)
Parameters
Type Name Description
PointF[] newPoints

Implements
