Render Objects Hierarchy

ComponentOne Reports for WinForms Designer Edition: ComponentOne Reports for WinForms > Working with C1PrintDocument > Render Objects > Render Objects Hierarchy

All content of a C1PrintDocument is represented by render objects. A rich hierarchy of render objects (based on the RenderObject class) is provided to represent different types of content. Below is the hierarchy of render object types, with a brief description for each class (note that italics indicate abstract classes):

Render Object Type				Description
RenderObject				The base class for all render objects.
	RenderArea			Represents a general-purpose container for render objects.
		RenderToc		Represents a table of contents.
		RenderReport		Represents a sub-report (a C1Report contained within a RenderField and specified by its SubReport property).
		RenderSection		Represents a section of an imported C1Report.
		RenderC1Printable		Represents an external object that can be seamlessly rendered in a C1PrintDocument. (The object must support the IC1Printable interface.)
	RenderEmpty			Represents an empty object. Provides a convenient placeholder for things like page breaks and so on where no content needs to be rendered.
	RenderGraphics			Represents a drawing on the .NET Graphics object.
	RenderImage			Represents an image.
	RenderInputBase			The abstract base class for all Preview Forms' input controls. Derived types represent active UI elements embedded in the document when the document is shown by the preview.
		RenderInputButtonBase		The abstract base class for button-like input controls (button, check box, radio button).
			RenderInputButton	Represents a push button.
			RenderInputCheckBox	Represents a checkbox.
			RenderInputRadioButton	Represents a radio button.
		RenderInputComboBox		Represents a combo box (text input control with a dropdown list).
		RenderInputText		Represents a textbox control.
	RenderRichText			Represents RTF text.
	RenderShapeBase			The abstract base class for classes representing shapes (lines, polygons and so on).
		RenderLineBase		The abstract base class for lines and polygons.
			RenderLine	Represents a line.
			RenderPolygon	Represents a closed or open polygon.
		RenderRectangle		Represents a rectangle.
			RenderEllipse	Represents an ellipse.
			RenderRoundRectangle	Represents a rectangle with rounded corners.
	RenderTable			Represents a table.
	RenderTextBase			The abstract base class for classes representing text and paragraph objects.
		RenderParagraph		Represents a paragraph (a run of text fragments in different styles, and inline images).
			RenderTocItem	Represents an entry in the table of contents (RenderToc).
		RenderText		Represents a piece of text rendered using a single style.
	RenderField			Represents a field of a C1Report. Objects of this type are created when a C1Report is imported into a C1PrintDocument.
	RenderBarCode			Represents a barcode.
