    public class QFont

extends QtJambiObject
implements java.lang.Comparable, java.lang.Cloneable

The QFont class specifies a font used for drawing text. When you create a QFont object you specify various attributes that you want the font to have. Qt will use the font with the specified attributes, or if no matching font exists, Qt will use the closest matching installed font. The attributes of the font that is actually used are retrievable from a `QFontInfo` object. If the window system provides an exact match `exactMatch()` returns true. Use `QFontMetrics` to get measurements, e.g. the pixel length of a string using `QFontMetrics::width()`.

Note that a `QApplication` instance must exist before a QFont can be used. You can set the application's default font with `QApplication::setFont()`.

If a chosen font does not include all the characters that need to be displayed, QFont will try to find the characters in the nearest equivalent fonts. When a `QPainter` draws a character from a font the QFont will report whether or not it has the character; if it does not, `QPainter` will draw an unfilled square.

Create QFonts like this:

            QFont serifFont = new QFont("Times", 10, QFont.Weight.Bold.value());
            QFont sansFont = new QFont("Helv etica [Cronyx]", 12);

The attributes set in the constructor can also be set later, e.g. `setFamily()`, `setPointSize()`, setPointSizeFloat(), `setWeight()` and `setItalic()`. The remaining attributes must be set after contstruction, e.g. `setBold()`, `setUnderline()`, `setOverline()`, `setStrikeOut()` and `setFixedPitch()`. `QFontInfo` objects should be created after the font's attributes have been set. A `QFontInfo` object will not change, even if you change the font's attributes. The corresponding "get" functions, e.g. `family()`, `pointSize()`, etc., return the values that were set, even though the values used may differ. The actual values are available from a `QFontInfo` object.

If the requested font family is unavailable you can influence the font matching algorithm by choosing a particular `QFont::StyleHint` and `QFont::StyleStrategy` with `setStyleHint()`. The default family (corresponding to the current style hint) is returned by `defaultFamily()`.

The font-matching algorithm has a `lastResortFamily()` and `lastResortFont()` in cases where a suitable match cannot be found. You can provide substitutions for font family names using `insertSubstitution()` and `insertSubstitutions()`. Substitutions can be removed with `removeSubstitution()`. Use `substitute()` to retrieve a family's first substitute, or the family name itself if it has no substitutes. Use `substitutes()` to retrieve a list of a family's substitutes (which may be empty).

Every QFont has a `key()` which you can use, for example, as the key in a cache or dictionary. If you want to store a user's font preferences you could use `QSettings`, writing the font information with `toString()` and reading it back with `fromString()`. The operator<<() and operator>>() functions are also available, but they work on a data stream.

It is possible to set the height of characters shown on the screen to a specified number of pixels with `setPixelSize()`; however using `setPointSize()` has a similar effect and provides device independence.

In X11 you can set a font using its system specific name with `setRawName()`.

Loading fonts can be expensive, especially on X11. QFont contains extensive optimizations to make the copying of QFont objects fast, and to cache the results of the slow window system functions it depends upon. The font matching algorithm works as follows:

1. The specified font family is searched for.
2. If not found, the `styleHint()` is used to select a replacement family.
3. Each replacement font family is searched for.
4. If none of these are found or there was no `styleHint()`, "helvetica" will be searched for.
5. If "helvetica" isn't found Qt will try the `lastResortFamily()`.
6. If the `lastResortFamily()` isn't found Qt will try the `lastResortFont()` which will always return a name of some kind.

Note that the actual font matching algorithm varies from platform to platform.

In Windows a request for the "Courier" font is automatically changed to "Courier New", an improved version of Courier that allows for smooth scaling. The older "Courier" bitmap font can be selected by setting the `PreferBitmap` style strategy (see `setStyleStrategy()`).

Once a font is found, the remaining attributes are matched in order of priority:

1. `fixedPitch()`
2. `pointSize()` (see below)
3. `weight()`
4. `style()`

If you have a font which matches on family, even if none of the other attributes match, this font will be chosen in preference to a font which doesn't match on family but which does match on the other attributes. This is because font family is the dominant search criteria.

The point size is defined to match if it is within 20% of the requested point size. When several fonts match and are only distinguished by point size, the font with the closest point size to the one requested will be chosen.

The actual family, font size, weight and other font attributes used for drawing text will depend on what's available for the chosen family under the window system. A `QFontInfo` object can be used to determine the actual values used for drawing the text.

Examples:

            QFont font = new QFont("Helvetica");

If you had both an Adobe and a Cronyx Helvetica, you might get either.

            QFont font = new QFont("Helvetica [Cronyx]");

You can specify the foundry you want in the family name. The font f in the above example will be set to "Helvetica [Cronyx]".

To determine the attributes of the font actually used in the window system, use a `QFontInfo` object, e.g.

            QFontInfo info = new QFontInfo(font);
            String family = info.family();

To find out font metrics use a `QFontMetrics` object, e.g.

            QFontMetrics fm = new QFontMetrics(font);
            int textWidthInPixels = fm.width("How many pixels wide is this text?");
            int textHeightInPixels = fm.height();

For more general information on fonts, see the comp.fonts FAQ. Information on encodings can be found from Roman Czyborra's page.

  Returns the window system handle to the font, for low-level access. Using this function is not portable.

### isCopyOf

    public final boolean isCopyOf(QFont arg__1)

  Returns true if this font and `f` are copies of each other, i.e. one of them was created as a copy of the other and neither has been modified since. This is much stricter than equality.

See also:
  operator=(), and operator==().

### italic

See also:
  QMap.

### lastResortFamily

    public final java.lang.String lastResortFamily()

  Returns the "last resort" font family name.

  The current implementation tries a wide variety of common fonts, returning the first one it finds. Is is possible that no family is found in which case an empty string is returned.

See also:

### lastResortFont

    public final java.lang.String lastResortFont()

  The current implementation tries a wide variety of common fonts, returning the first one it finds. The implementation may change at any time, but this function will always return a string containing something.

  It is theoretically possible that there really isn't a `lastResortFont()` in which case Qt will abort with an error message. We have not been able to identify a case where this happens. Please report it as a bug if it does, preferably with a list of the fonts you have installed.

  `setPointSize()`, and `pointSizeF()`.

### pointSizeF

    public final double pointSizeF()

  Returns the point size of the font. Returns -1 if the font size was specified in pixels.

See also:
  `pointSize()`, `setPointSizeF()`, `pixelSize()`, `QFontInfo::pointSize()`, and `QFontInfo::pixelSize()`.

### rawMode

    public final boolean rawMode()

  Returns true if raw mode is used for font name matching; otherwise returns false.

See also:
  `setRawMode()`, and `rawName()`.

### rawName

    public final java.lang.String rawName()

  Returns the name of the font within the underlying window system.

  Only on X11 when Qt was built without FontConfig support the XLFD (X Logical Font Description) is returned; otherwise an empty string.

See also:
  `setRawName()`.

### resolve

    public final QFont resolve(QFont arg__1)

  Returns a new QFont that has attributes copied from `other` that have not been previously set on this font.

### setBold

See also:
  `bold()`, and `setWeight()`.

### setCapitalization

    public final void setCapitalization(QFont.Capitalization arg__1)

  Sets the capitalization of the text in this font to `caps`.

  A font's capitalization makes the text appear in the selected capitalization mode.

See also:
  `capitalization()`.

### setFamily

    public final void setFamily(java.lang.String arg__1)

  Sets the family name of the font. The name is case insensitive and may include a foundry name.

  The `family` name may optionally also include a foundry name, e.g. "Helvetica [Cronyx]". If the `family` is available from more than one foundry and the foundry isn't specified, an arbitrary foundry is chosen. If the family isn't available a family will be set using the font matching algorithm.

See also:
  `family()`, `setStyleHint()`, and `QFontInfo`.

### setFixedPitch

    public final void setFixedPitch(boolean arg__1)

See also:
  `italic()`, and `QFontInfo`.

### setKerning

    public final void setKerning(boolean arg__1)

  Enables kerning for this font if `enable` is true; otherwise disables it. By default, kerning is enabled.

  When kerning is enabled, glyph metrics do not add up anymore, even for Latin text. In other words, the assumption that width('a') + width('b') is equal to width("ab") is not neccesairly true.

See also:
  `kerning()`, and `QFontMetrics`.

### setLetterSpacing

    public final void setLetterSpacing(QFont.SpacingType type,
                                       double spacing)

  Sets the letter spacing for the font to `spacing` and the type of spacing to `type`.

  Letter spacing changes the default spacing between individual letters in the font. The spacing between the letters can be made smaller as well as larger.

See also:
  `letterSpacing()`, `letterSpacingType()`, and `setWordSpacing()`.

### setOverline

    public final void setOverline(boolean arg__1)

  If `enable` is true, sets overline on; otherwise sets overline off.

See also:
  `overline()`, and `QFontInfo`.

### setPixelSize

    public final void setPixelSize(int arg__1)

  Sets the font size to `pixelSize` pixels.

  Using this function makes the font device dependent. Use `setPointSize()` or `setPointSizeF()` to set the size of the font in a device independent manner.

See also:
  `pixelSize()`.

### setPointSize

    public final void setPointSize(int arg__1)

  Sets the point size to `pointSize`. The point size must be greater than zero.

See also:
  `pointSize()`, and `setPointSizeF()`.

### setPointSizeF

    public final void setPointSizeF(double arg__1)

  Sets the point size to `pointSize`. The point size must be greater than zero. The requested precision may not be achieved on all platforms.

See also:
  `pointSizeF()`, `setPointSize()`, and `setPixelSize()`.

### setRawMode

    public final void setRawMode(boolean arg__1)

  If `enable` is true, turns raw mode on; otherwise turns raw mode off. This function only has an effect under X11.

  If raw mode is enabled, Qt will search for an X font with a complete font name matching the family name, ignoring all other values set for the QFont. If the font name matches several fonts, Qt will use the first font returned by X. `QFontInfo`cannot be used to fetch information about a QFont using raw mode (it will return the values set in the QFont for all parameters, including the family name).

  Warning: Do not use raw mode unless you really, really need it! In most (if not all) cases, `setRawName()` is a much better choice.

See also:
  `rawMode()`, and `setRawName()`.

### setRawName

    public final void setRawName(java.lang.String arg__1)

  Sets a font by its system specific name. The function is particularly useful under X, where system font settings (for example X resources) are usually available in XLFD (X Logical Font Description) form only. You can pass an XLFD as `name` to this function.

  A font set with `setRawName()` is still a full-featured QFont. It can be queried (for example with `italic()`) or modified (for example with `setItalic()`) and is therefore also suitable for rendering rich text.

  If Qt's internal font database cannot resolve the raw name, the font becomes a raw font with `name` as its family.

  Note that the present implementation does not handle wildcards in XLFDs well, and that font aliases (file `fonts.alias` in the font directory on X11) are not supported.

See also:
  `rawName()`, `setRawMode()`, and `setFamily()`.

### setStretch

    public final void setStretch(int arg__1)

  Sets the stretch factor for the font.

  The stretch factor changes the width of all characters in the font by `factor` percent. For example, setting `factor` to 150 results in all characters in the font being 1.5 times (ie. 150%) wider. The default stretch factor is 100. The minimum stretch factor is 1, and the maximum stretch factor is 4000.

  The stretch factor is only applied to outline fonts. The stretch factor is ignored for bitmap fonts.

  NOTE: QFont cannot stretch XLFD fonts. When loading XLFD fonts on X11, the stretch factor is matched against a predefined set of values for the SETWIDTH_NAME field of the XLFD.

  `stretch()`, and `QFont::Stretch` .

### setStrikeOut

    public final void setStrikeOut(boolean arg__1)

  If `enable` is true, sets strikeout on; otherwise sets strikeout off.

See also:
  `strikeOut()`, and `QFontInfo`.

### setStyle

    public final void setStyle(QFont.Style style)

  Sets the style of the font to `style`.

See also:
  `style()`, `italic()`, and `QFontInfo`.

### setStyleHint

    public final void setStyleHint(QFont.StyleHint arg__1)

  Sets the style hint and strategy to `hint` and `strategy`, respectively.

  If these aren't set explicitly the style hint will default to `AnyStyle` and the style strategy to `PreferDefault`.

  Qt does not support style hints on X11 since this information is not provided by the window system.

See also:
  `StyleHint` , `styleHint()`, `StyleStrategy` , `styleStrategy()`, and `QFontInfo`.

### setStyleHint

    public final void setStyleHint(QFont.StyleHint arg__1,
                                   QFont.StyleStrategy arg__2)

  Sets the style hint and strategy to `hint` and `strategy`, respectively.

  If these aren't set explicitly the style hint will default to `AnyStyle` and the style strategy to `PreferDefault`.

  Qt does not support style hints on X11 since this information is not provided by the window system.

See also:
  `StyleHint` , `styleHint()`, `StyleStrategy` , `styleStrategy()`, and `QFontInfo`.

### setStyleStrategy

    public final void setStyleStrategy(QFont.StyleStrategy s)

  Sets the style strategy for the font to `s`.

See also:
  `styleStrategy()`, and `QFont::StyleStrategy` .

### setUnderline

    public final void setUnderline(boolean arg__1)

  If `enable` is true, sets underline on; otherwise sets underline off.

See also:
  `underline()`, and `QFontInfo`.

### setWeight

    public final void setWeight(int arg__1)

  Sets the weight the font to `weight`, which should be a value from the `QFont::Weight` enumeration.

See also:
  `weight()`, and `QFontInfo`.

### setWordSpacing

    public final void setWordSpacing(double spacing)

  Sets the word spacing for the font to `spacing`.

  Word spacing changes the default spacing between individual words. A positive value increases the word spacing by a corresponding amount of pixels, while a negative value decreases the inter-word spacing accordingly.

  Word spacing will not apply to writing systems, where indiviaul words are not separated by white space.

  `wordSpacing()`, and `setLetterSpacing()`.

### stretch

    public final int stretch()

  Returns the stretch factor for the font.
