## Detailed Description

A font is an object which determines the appearance of text.

Fonts are used for drawing text to a device context, and setting the appearance of a window's text, see wxDC::SetFont() and wxWindow::SetFont().

The easiest way to create a custom font is to use wxFontInfo object to specify the font attributes and then use wxFont::wxFont(const wxFontInfo&) constructor. Alternatively, you could start with one of the pre-defined fonts or use wxWindow::GetFont() and modify the font, e.g. by increasing its size using MakeLarger() or changing its weight using MakeBold().

This class uses reference counting and copy-on-write internally so that assignments between two instances of this class are very cheap. You can therefore use actual objects instead of pointers without efficiency problems. If an instance of this class is changed it will create its own data internally so that other instances, which previously shared the data using the reference counting, are not affected.

You can retrieve the current system font settings with wxSystemSettings.

## Constructor & Destructor Documentation

wxFont::wxFont | ( |  | ) |

Default ctor.

wxFont::wxFont | ( | const wxFont & | font | ) |

Copy constructor, uses reference counting.

wxFont::wxFont | ( | const wxFontInfo & | fontInfo | ) |

Creates a font object using the specified font description.

This is the preferred way to create font objects as using this ctor results in more readable code and it is also extensible, e.g. it could continue to be used if support for more font attributes is added in the future. For example, this constructor provides the only way of creating fonts with strike-through style.

Example of creating a font using this ctor:

wxFont font(wxFontInfo(10).Bold().Underlined());

Since
  2.9.5

wxFont::wxFont | ( | int | pointSize,
|  | wxFontFamily | family,
|  | wxFontStyle | style,
|  | wxFontWeight | weight,
|  | bool | underline = `false`,
|  | const wxString & | faceName = `wxEmptyString`,
|  | wxFontEncoding | encoding = `wxFONTENCODING_DEFAULT`
| ) |  |

Creates a font object with the specified attributes and size in points.

Notice that the use of this constructor is often more verbose and less readable than the use of constructor from wxFontInfo, e.g. the example in that constructor documentation would need to be written as

wxFont font(10, wxFONTFAMILY_DEFAULT, wxFONTSTYLE_NORMAL,
wxFONTWEIGHT_BOLD, true);

which is longer and less clear.

Parameters

  pointSize | Size in points. See SetPointSize() for more info.
  family | The font family: a generic portable way of referring to fonts without specifying a facename. This parameter must be one of the wxFontFamily enumeration values. If the faceName argument is provided, then it overrides the font family.
  style | One of `wxFONTSTYLE_NORMAL`, `wxFONTSTYLE_SLANT` and `wxFONTSTYLE_ITALIC`.
  weight | Font weight, sometimes also referred to as font boldness. One of the wxFontWeight enumeration values.
  underline | The value can be true or false. At present this has an effect on Windows and Motif 2.x only.
  faceName | An optional string specifying the face name to be used. If it is an empty string, a default face name will be chosen based on the family.
  encoding | An encoding which may be one of the enumeration values of wxFontEncoding. Briefly these can be summed up as:
  `wxFONTENCODING_SYSTEM` | Default system encoding.
  `wxFONTENCODING_DEFAULT` | Default application encoding: this is the encoding set by calls to SetDefaultEncoding() and which may be set to, say, KOI8 to create all fonts by default with KOI8 encoding. Initially, the default application encoding is the same as default system encoding.
  `wxFONTENCODING_ISO8859_1`...15 | ISO8859 encodings.
  `wxFONTENCODING_KOI8` | The standard Russian encoding for Internet.
  `wxFONTENCODING_CP1250`...1252 | Windows encodings similar to ISO8859 (but not identical).
  If the specified encoding isn't available, no font is created (see also Font Encodings).

Remarks
  If the desired font does not exist, the closest match will be chosen. Under Windows, only scalable TrueType fonts are used.

wxFont::wxFont | ( | const wxSize & | pixelSize,
|  | wxFontFamily | family,
|  | wxFontStyle | style,
|  | wxFontWeight | weight,
|  | bool | underline = `false`,
|  | const wxString & | faceName = `wxEmptyString`,
|  | wxFontEncoding | encoding = `wxFONTENCODING_DEFAULT`
| ) |  |

Creates a font object with the specified attributes and size in pixels.

Notice that the use of this constructor is often more verbose and less readable than the use of constructor from wxFontInfo, consider using that constructor instead.

Parameters

  pixelSize | Size in pixels. See SetPixelSize() for more info.
  family | The font family: a generic portable way of referring to fonts without specifying a facename. This parameter must be one of the wxFontFamily enumeration values. If the faceName argument is provided, then it overrides the font family.
  style | One of `wxFONTSTYLE_NORMAL`, `wxFONTSTYLE_SLANT` and `wxFONTSTYLE_ITALIC`.
  weight | Font weight, sometimes also referred to as font boldness. One of the wxFontWeight enumeration values.
  underline | The value can be true or false. At present this has an effect on Windows and Motif 2.x only.
  faceName | An optional string specifying the face name to be used. If it is an empty string, a default face name will be chosen based on the family.
  encoding | An encoding which may be one of the enumeration values of wxFontEncoding. Briefly these can be summed up as:
  `wxFONTENCODING_SYSTEM` | Default system encoding.
  `wxFONTENCODING_DEFAULT` | Default application encoding: this is the encoding set by calls to SetDefaultEncoding() and which may be set to, say, KOI8 to create all fonts by default with KOI8 encoding. Initially, the default application encoding is the same as default system encoding.
  `wxFONTENCODING_ISO8859_1`...15 | ISO8859 encodings.
  `wxFONTENCODING_KOI8` | The standard Russian encoding for Internet.
  `wxFONTENCODING_CP1250`...1252 | Windows encodings similar to ISO8859 (but not identical).
  If the specified encoding isn't available, no font is created (see also Font Encodings).

Remarks
  If the desired font does not exist, the closest match will be chosen. Under Windows, only scalable TrueType fonts are used.

wxFont::wxFont | ( | const wxString & | nativeInfoString | ) |

Constructor from font description string.

This constructor uses SetNativeFontInfo() to initialize the font. If fontdesc is invalid the font remains uninitialized, i.e. its IsOk() method will return false.

wxFont::wxFont | ( | const wxNativeFontInfo & | nativeInfo | ) |

Construct font from a native font info structure.

virtual wxFont::~wxFont | ( |  | ) |
| virtual

Destructor.

See reference-counted object destruction for more info.

Remarks
  Although all remaining fonts are deleted when the application exits, the application should try to clean up all fonts itself. This is because wxWidgets cannot know if a pointer to the font object is stored in an application data structure, and there is a risk of double deletion.

## Member Function Documentation

wxFont wxFont::Bold | ( |  | ) | const

Returns a bold version of this font.

See also
  MakeBold()

Since
  2.9.1

static wxFontEncoding wxFont::GetDefaultEncoding | ( |  | ) |
| static

Returns the current application's default encoding.

See also
  Font Encodings, SetDefaultEncoding()

virtual wxFontEncoding wxFont::GetEncoding | ( |  | ) | const
| virtual

Returns the encoding of this font.

Note that under wxGTK the returned value is always `wxFONTENCODING_UTF8`.

See also
  SetEncoding()

virtual wxString wxFont::GetFaceName | ( |  | ) | const
| virtual

Returns the face name associated with the font, or the empty string if there is no face information.

See also
  SetFaceName()

virtual wxFontFamily wxFont::GetFamily | ( |  | ) | const
| virtual

Gets the font family if possible.

As described in wxFontFamily docs the returned value acts as a rough, basic classification of the main font properties (look, spacing).

If the current font face name is not recognized by wxFont or by the underlying system, `wxFONTFAMILY_DEFAULT` is returned.

Note that currently this function is not very precise and so not particularly useful. Font families mostly make sense only for font creation, see SetFamily().

See also
  SetFamily()

const wxNativeFontInfo* wxFont::GetNativeFontInfo | ( |  | ) | const

Returns the encoding of this font.

Note that under wxGTK the returned value is always `wxFONTENCODING_UTF8`.

See also
  SetEncoding()

wxString wxFont::GetNativeFontInfoDesc | ( |  | ) | const

Returns the platform-dependent string completely describing this font.

Returned string is always non-empty unless the font is invalid (in which case an assert is triggered).

Note that the returned string is not meant to be shown or edited by the user: a typical use of this function is for serializing in string-form a wxFont object.

See also
  SetNativeFontInfo(), GetNativeFontInfoUserDesc()

wxString wxFont::GetNativeFontInfoUserDesc | ( |  | ) | const

Returns a user-friendly string for this font object.

Returned string is always non-empty unless the font is invalid (in which case an assert is triggered).

The string does not encode all wxFont infos under all platforms; e.g. under wxMSW the font family is not present in the returned string.

Some examples of the formats of returned strings (which are platform-dependent) are in SetNativeFontInfoUserDesc().

See also
  SetNativeFontInfoUserDesc(), GetNativeFontInfoDesc()

virtual wxSize wxFont::GetPixelSize | ( |  | ) | const
| virtual

Gets the pixel size.

Note that under wxMSW if you passed to SetPixelSize() (or to the ctor) a wxSize object with a null width value, you'll get a null width in the returned object.

See also
  SetPixelSize()

virtual int wxFont::GetPointSize | ( |  | ) | const
| virtual

Gets the point size.

See also
  SetPointSize()

virtual bool wxFont::GetStrikethrough | ( |  | ) | const
| virtual

Returns true if the font is stricken-through, false otherwise.

See also
  SetStrikethrough()

Since
  2.9.4

virtual wxFontStyle wxFont::GetStyle | ( |  | ) | const
| virtual

Gets the font style.

See wxFontStyle for a list of valid styles.

See also
  SetStyle()

virtual bool wxFont::GetUnderlined | ( |  | ) | const
| virtual

Returns true if the font is underlined, false otherwise.

See also
  SetUnderlined()

virtual wxFontWeight wxFont::GetWeight | ( |  | ) | const
| virtual

Gets the font weight.

See wxFontWeight for a list of valid weight identifiers.

See also
  SetWeight()

virtual bool wxFont::IsFixedWidth | ( |  | ) | const
| virtual

Returns true if the font is a fixed width (or monospaced) font, false if it is a proportional one or font is invalid.

Note that this function under some platforms is different than just testing for the font family being equal to `wxFONTFAMILY_TELETYPE` because native platform-specific functions are used for the check (resulting in a more accurate return value).

virtual bool wxFont::IsOk | ( |  | ) | const
| virtual

Returns true if this object is a valid font, false otherwise.

wxFont wxFont::Italic | ( |  | ) | const

Returns an italic version of this font.

See also
  MakeItalic()

Since
  2.9.1

wxFont wxFont::Larger | ( |  | ) | const

Returns a larger version of this font.

The font size is multiplied by `1.2`, the factor of `1.2` being inspired by the W3C CSS specification.

See also
  MakeLarger(), Smaller(), Scaled()

static void wxFont::SetDefaultEncoding | ( | wxFontEncoding | encoding | ) |
| static

Sets the default font encoding.

See also
  Font Encodings, GetDefaultEncoding()

virtual void wxFont::SetEncoding | ( | wxFontEncoding | encoding | ) |
| virtual

Sets the encoding for this font.

Note that under wxGTK this function has no effect (because the underlying Pango library always uses `wxFONTENCODING_UTF8`).

See also
  GetEncoding()

virtual bool wxFont::SetFaceName | ( | const wxString & | faceName | ) |
| virtual

Sets the facename for the font.

Parameters

  faceName | A valid facename, which should be on the end-user's system.

Remarks
  To avoid portability problems, don't rely on a specific face, but specify the font family instead (see wxFontFamily and SetFamily()).

Returns
  true if the given face name exists; if the face name doesn't exist in the user's system then the font is invalidated (so that IsOk() will return false) and false is returned.

See also
  GetFaceName(), SetFamily()

virtual void wxFont::SetFamily | ( | wxFontFamily | family | ) |
| virtual

Sets the font family.

As described in wxFontFamily docs the given family value acts as a rough, basic indication of the main font properties (look, spacing).

Note that changing the font family results in changing the font face name.

Parameters

  family | One of the wxFontFamily values.

See also
  GetFamily(), SetFaceName()

bool wxFont::SetNativeFontInfo | ( | const wxString & | info | ) |

Creates the font corresponding to the given native font description string which must have been previously returned by GetNativeFontInfoDesc().

If the string is invalid, font is unchanged. This function is typically used for de-serializing a wxFont object previously saved in a string-form.

Returns
  true if the creation was successful.

See also
  SetNativeFontInfoUserDesc()

void wxFont::SetNativeFontInfo | ( | const wxNativeFontInfo & | info | ) |

Sets the encoding for this font.

Note that under wxGTK this function has no effect (because the underlying Pango library always uses `wxFONTENCODING_UTF8`).

See also
  GetEncoding()

bool wxFont::SetNativeFontInfoUserDesc | ( | const wxString & | info | ) |

Creates the font corresponding to the given native font description string and returns true if the creation was successful.

Unlike SetNativeFontInfo(), this function accepts strings which are user-friendly. Examples of accepted string formats are:

platform | generic syntax | example
--- | --- | ---
wxGTK2 | `[underlined] [strikethrough] [FACE-NAME] [bold] [oblique|italic] [POINTSIZE]` | Monospace bold 10
wxMSW | `[light|bold] [italic] [FACE-NAME] [POINTSIZE] [ENCODING]` | Tahoma 10 WINDOWS-1252

Todo:
  add an example for wxMac

For more detailed information about the allowed syntaxes you can look at the documentation of the native API used for font-rendering (e.g. `pango_font_description_from_string` under GTK, although notice that it doesn't support the "underlined" and "strikethrough" attributes and so those are handled by wxWidgets itself).

Note that unlike SetNativeFontInfo(), this function doesn't always restore all attributes of the wxFont object under all platforms; e.g. on wxMSW the font family is not restored (because GetNativeFontInfoUserDesc doesn't return it on wxMSW). If you want to serialize/deserialize a font in string form, you should use GetNativeFontInfoDesc() and SetNativeFontInfo() instead.

virtual void wxFont::SetPixelSize | ( | const wxSize & | pixelSize | ) |
| virtual

Sets the pixel size.

The height parameter of pixelSize must be positive while the width parameter may also be zero (to indicate that you're not interested in the width of the characters: a suitable width will be chosen for best rendering).

This feature (specifying the font pixel size) is directly supported only under wxMSW and wxGTK currently; under other platforms a font with the closest size to the given one is found using binary search (this maybe slower).

virtual void wxFont::SetPointSize | ( | int | pointSize | ) |
| virtual

Sets the point size.

The point size is defined as 1/72 of the Anglo-Saxon inch (25.4 mm): it is approximately 0.0139 inch or 352.8 um.

Parameters

  pointSize | Size in points.

virtual void wxFont::SetStrikethrough | ( | bool | strikethrough | ) |
| virtual

Sets strike-through attribute of the font.

Currently stricken-through fonts are only supported in wxMSW and wxGTK.

Parameters

  strikethrough | true to add strike-through style, false to remove it.

Since
  2.9.4

virtual void wxFont::SetStyle | ( | wxFontStyle | style | ) |
| virtual

Sets the font style.

Parameters

  style | One of the wxFontStyle enumeration values.

  GetStyle()

void wxFont::SetSymbolicSize | ( | wxFontSymbolicSize | size | ) |

Sets the font size using a predefined symbolic size name.

This function allows changing font size to be (very) large or small compared to the standard font size.

See also
  SetSymbolicSizeRelativeTo().

Since
  2.9.2

void wxFont::SetSymbolicSizeRelativeTo | ( | wxFontSymbolicSize | size,
|  | int | base
| ) |  |

Sets the font size compared to the base font size.

This is the same as SetSymbolicSize() except that it uses the given font size as the normal font size instead of the standard font size.

Since
  2.9.2

virtual void wxFont::SetUnderlined | ( | bool | underlined | ) |
| virtual

Sets underlining.

Parameters

  underlined | true to underline, false otherwise.

  GetUnderlined()

virtual void wxFont::SetWeight | ( | wxFontWeight | weight | ) |
| virtual

Sets the font weight.

Parameters

  weight | One of the wxFontWeight values.
