Methods

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
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 method.

Deserialize(FRReader)

Deserializes the object.

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

Reader object.

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 restore the state. It may happen when:

  • loading the report from a file or stream;
  • loading the report from the designer's undo buffer;
  • assigning another object to this object using the Assign(Base) or AssignAll methods;
  • loading the object from the designer's clipboard;
  • loading the object from the preview pages.

Draw(FRPaintEventArgs)

Draws the shape.

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

Object that provides a data for paint event.
Overrides

DrawLabel(FRPaintEventArgs)

Draws the label.

Declaration
public override void DrawLabel(FRPaintEventArgs e)
Parameters
Type Name Description
FRPaintEventArgs e

Object that provides a data for paint event.
Overrides

FinalizeComponent()

Finalizes a component before running a report.

Declaration
public override void FinalizeComponent()
Overrides

HitTest(PointF)

Checks if the shape is under cursor.

Declaration
public override bool HitTest(PointF point)
Parameters
Type Name Description
System.Drawing.PointF point

The cursor coordinates.
Returns
Type Description
System.Boolean

true if the cursor is over the shape.
Overrides

InitializeComponent()

Initializes a component before running a report.

Declaration
public override void InitializeComponent()
Overrides

Serialize(FRWriter)

Serializes the object.

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

Writer object.
Overrides
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 methods;
  • saving the object to the designer's clipboard;
  • saving the object to the preview (when run a report).

Simplify(Double)

Reduces the number of points in the shape.

Declaration
public override void Simplify(double accuracy)
