The text node source.

Initializes a new instance of the TextNode class.

Declaration
protected TextNode(SerializationInfo info, StreamingContext context)
Parameters
Type Name Description
System.Runtime.Serialization.SerializationInfo info

The info.
System.Runtime.Serialization.StreamingContext context

The context.

TextNode(String)

Initializes a new instance of the TextNode class.

Declaration

The text.

TextNode(String, RectangleF)

Initializes a new instance of the TextNode class.

Declaration
public TextNode(string strText, RectangleF rectBounds)
Parameters
Type Name Description

The text.
System.Drawing.RectangleF rectBounds

The rect bounds.

TextNode(String, RectangleF, MeasureUnits)

Declaration
public TextNode(string strText, RectangleF rectBounds, MeasureUnits measureUnits)

Properties

BackgroundStyle

Gets text background style.

Declaration
public FillStyle BackgroundStyle { get; }
Property Value
Type
FillStyle

DirectionRightToLeft

Gets or sets a value indicating whether the text is right to left.

Declaration
public bool DirectionRightToLeft { get; set; }
Property Value
Type
System.Boolean

DirectionVertical

Gets or sets a value indicating whether the text is vertical.

Declaration
public bool DirectionVertical { get; set; }
Property Value
Type
System.Boolean

FitBlackBox

Gets or sets a value indicating whether no part of any glyph overhangs the bounding rectangle.

Declaration
public bool FitBlackBox { get; set; }
Property Value
Type
System.Boolean
Remarks

By default some glyphs overhang the rectangle slightly where necessary to appear at the edge visually. For example when an italic lowercase letter f in a font such as Garamond is aligned at the far left of a rectangle, the lower part of the f will reach slightly further left than the left edge of the rectangle. Setting this flag will ensure no painting outside the rectangle but will cause the aligned edges of adjacent lines of text to appear uneven.

FontColorStyle

Gets font color style.

Declaration
public FillStyle FontColorStyle { get; }
Property Value
Type
FillStyle

FontStyle

Gets the font used to draw the text.

Declaration
public FontStyle FontStyle { get; }
Property Value
Type
FontStyle

FormatFlags

Gets flags used to format the text.

Declaration
public StringFormatFlags FormatFlags { get; }
Property Value
Type
System.Drawing.StringFormatFlags
Remarks

See System.Drawing.StringFormatFlags for more details.

HorizontalAlignment

Specifies how an object or text in a control is horizontally aligned relative to an element of the control.

Declaration
public StringAlignment HorizontalAlignment { get; set; }
Property Value
Type
System.Drawing.StringAlignment
Remarks

This property is used by the GetStringFormat() method to generate a System.Drawing.StringFormat object. This property corresponds to the Alignment property in the System.Drawing.StringFormat class.

LineLimit

Gets or sets a value indicating whether only entire lines are laid out in the formatting rectangle.

Declaration
public bool LineLimit { get; set; }
Property Value
Type
System.Boolean
Remarks

By default, layout continues until the end of the text, or until no more lines are visible as a result of clipping, whichever comes first. Note that the default settings allow the last line to be partially obscured by a formatting rectangle that is not a whole multiple of the line height. To ensure that only whole lines are seen, specify this value and be careful to provide a formatting rectangle at least as tall as the height of one line.

MeasureTrailingSpaces

Gets or sets a value indicating whether space at the end of each line in calculations that measure the size of the text.

Declaration
public bool MeasureTrailingSpaces { get; set; }
Property Value
Type
System.Boolean
Remarks

By default, the boundary rectangle returned by the MeasureString method excludes the space at the end of each line. Set this flag to include that space in measurement.

NoClip

Gets or sets a value indicating whether overhanging parts of glyphs and unwrapped text reaching outside the formatting rectangle are allowed to show.

Declaration
public bool NoClip { get; set; }
Property Value
Type
System.Boolean
Remarks

By default, all text and glyph parts reaching outside the formatting rectangle are clipped.

ReadOnly

Gets or sets a value indicating whether the text object is Read-only or not.

Declaration
public bool ReadOnly { get; set; }
Property Value
Type
System.Boolean

Text

Gets or sets the value contained by the text object.

Declaration
public string Text { get; set; }
Property Value
Type
System.String
Remarks

Derived classes override this property in order to supply the text value in an implementation-specific way.

TextCase

Gets or sets case of text in the RichTextNode

Declaration
public TextCases TextCase { get; set; }
Property Value
Type
TextCases

VerticalAlignment

Gets or sets the vertical alignment of the text.

Declaration
public StringAlignment VerticalAlignment { get; set; }
Property Value
Type
System.Drawing.StringAlignment
Remarks

This property is used by the GetStringFormat() method to generate a System.Drawing.StringFormat object. This property corresponds to the LineAlignment property in the System.Drawing.StringFormat class.

WrapText

Gets or sets a value indicating whether text should be wrapped when it exceeds the width of the bounding box.

Declaration
public bool WrapText { get; set; }
Property Value
Type
System.Boolean
