- Attributes
Fields
| Name | Value | Description |
|---|---|---|
| Default | 0 | Applies the default formatting, which is left-aligned. |
| GlyphOverhangPadding | 0 | Adds padding to the bounding rectangle to accommodate overhanging glyphs. This is the default. |
| Left | 0 | Aligns the text on the left side of the clipping area. This is the default. |
| Top | 0 | Aligns the text on the top of the bounding rectangle. This is the default. |
| HorizontalCenter | 1 | Centers the text horizontally within the bounding rectangle. |
| Right | 2 | Aligns the text on the right side of the clipping area. |
| VerticalCenter | 4 | Centers the text vertically, within the bounding rectangle. |
| Bottom | 8 | Aligns the text on the bottom of the bounding rectangle. Applied only when the text is a single line. |
| WordBreak | 16 | Breaks the text at the end of a word. |
| SingleLine | 32 | Displays the text in a single line. |
| ExpandTabs | 64 | Expands tab characters. The default number of characters per tab is eight. The WordEllipsis, PathEllipsis, and EndEllipsis values cannot be used with ExpandTabs. |
| NoClipping | 256 | Allows the overhanging parts of glyphs and unwrapped text reaching outside the formatting rectangle to show. |
| ExternalLeading | 512 | Includes the font external leading in line height. Typically, external leading is not included in the height of a line of text. |
| NoPrefix | 2048 | Turns off processing of prefix characters. Typically, the ampersand (&) mnemonic-prefix character is interpreted as a directive to underscore the character that follows, and the double-ampersand (&&) mnemonic-prefix characters as a directive to print a single ampersand. By specifying NoPrefix, this processing is turned off. For example, an input string of "A&bc&&d" with NoPrefix applied would result in output of "A&bc&&d". Compare with |
| Internal | 4096 | Uses the system font to calculate text metrics. |
| TextBoxControl | 8192 | Specifies the text should be formatted for display on a TextBox control. |
| PathEllipsis | 16384 | Removes the center of trimmed lines and replaces it with an ellipsis. When used to draw text by |
| EndEllipsis | 32768 | Removes the end of trimmed lines, and replaces them with an ellipsis. When used to draw text by |
| ModifyString | 65536 | Has no effect on the drawn text or text measurements. When used to draw text by |
| RightToLeft | 131072 | Displays the text from right to left. |
| WordEllipsis | 262144 | Trims the line to the nearest word and an ellipsis is placed at the end of a trimmed line. Compare with EndEllipsis and PathEllipsis. |
| NoFullWidthCharacterBreak | 524288 | A legacy value that has no effect. It prevents a line break at a double-wide character string, so that the line-breaking rule is equivalent to that for single-wide character strings. |
| HidePrefix | 1048576 | Ignores the ampersand (&) prefix character in the text, so that the letter that follows won't be underlined, but other mnemonic-prefix characters are still processed. |
| PrefixOnly | 2097152 | Draws only an underline at the position of the character following the ampersand (&) prefix character and doesn't draw any other characters in the string. |
| PreserveGraphicsClipping | 16777216 | Preserves the clipping specified by a Graphics object. Applies only to methods receiving an IDeviceContext that is a Graphics. |
| PreserveGraphicsTranslateTransform | 33554432 | Preserves the transformation specified by a Graphics. Applies only to methods receiving an IDeviceContext that is a Graphics. |
| NoPadding | 268435456 | Does not add padding to the bounding rectangle. |
| LeftAndRightPadding | 536870912 | Adds padding to both sides of the bounding rectangle. |
Examples
The following example demonstrates how to use the TextFormatFlags enumeration. To run this example, paste the following code into a Windows Form. Call RenderText6 from the form's Paint event handler, passing e as PaintEventArgs.
private void RenderText6(PaintEventArgs e)
{
TextFormatFlags flags = TextFormatFlags.Bottom | TextFormatFlags.EndEllipsis;
TextRenderer.DrawText(e.Graphics, "This is some text that will be clipped at the end.", this.Font,
new Rectangle(10, 10, 100, 50), SystemColors.ControlText, flags);
}
Private Sub RenderText6(ByVal e As PaintEventArgs)
Dim flags As TextFormatFlags = TextFormatFlags.Bottom Or _
TextFormatFlags.EndEllipsis
TextRenderer.DrawText(e.Graphics, _
"This is some text that will be clipped at the end.", _
Me.Font, New Rectangle(10, 10, 100, 50), SystemColors.ControlText, flags)
End Sub
Remarks
The TextFormatFlags enumeration is used by the TextRenderer when drawing and measuring text. The TextRenderer does not support adding tab stops to drawn text, although you can expand existing tab stops using the ExpandTabs flag.
