Interface ITagPainter

Interface implemented by components that provide customized rendering of tags in the edit control.

public interface ITagPainter

Draw a placeholder node.

void DrawPlaceholderTag(Graphics g, Rectangle boundingBox, IPlaceholderNode placeholderNode, string displayText)

Type	Name	Description
System.Drawing.Graphics	g	The graphics context to use for drawing
System.Drawing.Rectangle	boundingBox	The bounding rectangle, who's size was determined from a previous call to GetPlaceholderTagSize(Graphics, IPlaceholderNode, String, ref Int32, ref Int32). Any drawing operations should be limited to this area, or they may overlap with other content.
IPlaceholderNode	placeholderNode	The node to be rendered
System.String	displayText	The tag's display text according to current tag display settings.

Draw a start/end node.

void DrawStartEndTag(Graphics g, Rectangle boundingBox, IStartEndNode startEndNode, string displayText, bool rtl)

Type	Name	Description
System.Drawing.Graphics	g	The graphics context to use for drawing
System.Drawing.Rectangle	boundingBox	The bounding rectangle, who's size was determined from a previous call to GetStartEndTagSize(Graphics, IStartEndNode, String, ref Int32, ref Int32). Any drawing operations should be limited to this area, or they may overlap with other content.
IStartEndNode	startEndNode	The node to be rendered
System.String	displayText	The tag's display text according to current tag display settings.
System.Boolean	rtl	The local writing direction around the tag pair: true for rtl, false for ltr

Gets the tag text that should be displayed on screen (eg, with line breaks, etc, removed).

string GetDisplayableTagText(string tagText)

Type	Name	Description
System.String	tagText

Type	Description
System.String

Calculate the size of a placeholder node and and ascent and descent for the tag in relation to any text that appears on it.

Size GetPlaceholderTagSize(Graphics g, IPlaceholderNode placeholderNode, string displayText, ref int ascent, ref int descent)

Type	Name	Description
System.Drawing.Graphics	g	The graphics context to use for drawing
IPlaceholderNode	placeholderNode	The node to be sized
System.String	displayText	The tag's display text according to current tag display settings.
System.Int32	ascent	Ascent of the font family used for tag display text, adjusted for the location of the text within the returned size
System.Int32	descent	Descent of the font family used for tag display text, adjusted for the location of the text within the returned size

Type	Description
System.Drawing.Size	The size of the (rectangular) area required to draw the tag.

The sum of ascent and descent should equal the tag height.

Calculate the size of a start/end node and and ascent and descent for the tag in relation to any text that appears on it.

System.String	displayText	The tag's display text according to current tag display settings.
System.Int32	ascent	Ascent of the font family used for tag display text, adjusted for the location of the text within the returned size
System.Int32	descent	Descent of the font family used for tag display text, adjusted for the location of the text within the returned size

Type	Description
System.Drawing.Size	The size of the (rectangular) area required to draw the tag.
