## ◆ BBox() [1/2]

virtual FTBBox FTSimpleLayout::BBox | ( | const char * | string,
|  | const int | len = -1,
|  | FTPoint | position = FTPoint() )
| virtual

Get the bounding box for a formatted string.

Parameters

  string | A char string.
  len | The length of the string. If < 0 then all characters will be checked until a null character is encountered (optional).
  position | The pen position of the first character (optional).

Returns
  The corresponding bounding box.

Implements FTLayout.

## ◆ BBox() [2/2]

virtual FTBBox FTSimpleLayout::BBox | ( | const wchar_t * | string,
|  | const int | len = -1,
|  | FTPoint | position = FTPoint() )
| virtual

Get the bounding box for a formatted string.

Parameters

  string | A wchar_t string.
  len | The length of the string. If < 0 then all characters will be checked until a null character is encountered (optional).
  position | The pen position of the first character (optional).

Returns
  The corresponding bounding box.

Implements FTLayout.

## ◆ GetAlignment()

FTGL::TextAlignment FTSimpleLayout::GetAlignment | ( |  | ) | const

Returns
  The text alignment mode.

## ◆ GetFont()

FTFont * FTSimpleLayout::GetFont | ( |  | ) |

Returns
  The current font.

## ◆ GetLineLength()

float FTSimpleLayout::GetLineLength | ( |  | ) | const

Returns
  The current line length.

## ◆ GetLineSpacing()

float FTSimpleLayout::GetLineSpacing | ( |  | ) | const

Returns
  The line spacing.

## ◆ Render() [1/2]

virtual void FTSimpleLayout::Render | ( | const char * | string,
|  | const int | len = -1,
|  | FTPoint | position = FTPoint(),
|  | int | renderMode = FTGL::RENDER_ALL )
| virtual

Render a string of characters.

Parameters

  string | 'C' style string to be output.
  len | The length of the string. If < 0 then all characters will be displayed until a null character is encountered (optional).
  position | The pen position of the first character (optional).
  renderMode | Render mode to display (optional)

Implements FTLayout.

## ◆ Render() [2/2]

virtual void FTSimpleLayout::Render | ( | const wchar_t * | string,
|  | const int | len = -1,
|  | FTPoint | position = FTPoint(),
|  | int | renderMode = FTGL::RENDER_ALL )
| virtual

Render a string of characters.

Parameters

  string | wchar_t string to be output.
  len | The length of the string. If < 0 then all characters will be displayed until a null character is encountered (optional).
  position | The pen position of the first character (optional).
  renderMode | Render mode to display (optional)

Implements FTLayout.

## ◆ SetAlignment()

void FTSimpleLayout::SetAlignment | ( | const FTGL::TextAlignment | Alignment | ) |

The text alignment mode used to distribute space within a line or rendered text.

Parameters

  Alignment | The new alignment mode.

## ◆ SetFont()

void FTSimpleLayout::SetFont | ( | FTFont * | fontInit | ) |

Set the font to use for rendering the text.

Parameters

  fontInit | A pointer to the new font. The font is referenced by this but will not be disposed of when this is deleted.

## ◆ SetLineLength()

void FTSimpleLayout::SetLineLength | ( | const float | LineLength | ) |

The maximum line length for formatting text.

Parameters

  LineLength | The new line length.

## ◆ SetLineSpacing()
