public class QFont
extends QtJambiObject
implements java.lang.Comparable

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().

Use QApplication::setFont() to set the application's default font.

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("Times", 10, Bold);
    QFont sansFont("Helvetica [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.

Under 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.

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 f("Helvetica");

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

    QFont f("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(f1);
    QString family = info.family();

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

    QFontMetrics fm(f1);
    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.

See Also:
setFixedPitch, QFontInfo::fixedPitch

fromString

Sets this font to match the description arg__1. The description is a comma-separated list of the font attributes, as returned by toString.

See Also:
toString

handle

public final long handle()

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 arg__1 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=, operator==

italic

public final boolean italic()

Returns true if the style of the font is not QFont::StyleNormal

See Also:
setItalic, style

kerning

public final boolean kerning()

Returns true if kerning should be used when drawing text with this font.

See Also:
setKerning

key

public final java.lang.String key()

Returns the font's key, a textual representation of a font. It is typically used as the key for a cache or dictionary of fonts.

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

lastResortFont

public final java.lang.String lastResortFont()

Returns a "last resort" font name for the font matching algorithm. This is used if the last resort family is not available. It will always return a name, if necessary returning something like "fixed" or "system".

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.

See Also:
lastResortFamily, rawName

writeTo

public final void writeTo(QDataStream arg__1)
Writes thisQFont to arg__1.


readFrom

public final void readFrom(QDataStream arg__1)
Reads a QFont from arg__1.


overline

public final boolean overline()

Returns true if overline has been set; otherwise returns false.

See Also:
setOverline

pixelSize

public final int pixelSize()

Returns the pixel size of the font if it was set with setPixelSize. Returns -1 if the size was set with setPointSize or setPointSizeF.

See Also:
setPixelSize, pointSize, QFontInfo::pointSize, QFontInfo::pixelSize

pointSize

public final int pointSize()

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

See Also:
setPointSize, 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, QFontInfo::pixelSize

rawMode

public final boolean rawMode()

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

See Also:
setRawMode, rawName

rawName

public final java.lang.String rawName()

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

On Windows and Mac OS X, this is usually just the family name of a TrueType font.

On X11, depending on whether Qt was built with FontConfig support, it is an XLFD (X Logical Font Description) or a FontConfig pattern. An XLFD may be returned even if FontConfig support is enabled.

Using the return value of this function is usually not portable.

See Also:
setRawName

resolve

public final int resolve()

This method is used internally by Qt Jambi. Do not use it in your applications.


resolve

public final void resolve(int mask)

This method is used internally by Qt Jambi. Do not use it in your applications.


resolve

public final QFont resolve(QFont arg__1)

Returns a new QFont that has attributes copied from arg__1 that have not been previously set on this font.


setBold

public final void setBold(boolean arg__1)

If arg__1 is true sets the font's weight to QFont::Bold; otherwise sets the weight to QFont::Normal.

For finer boldness control use setWeight.

See Also:
bold, setWeight

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 arg__1 name may optionally also include a foundry name, e.g. "Helvetica [Cronyx]". If the arg__1 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, QFontInfo

setFixedPitch

public final void setFixedPitch(boolean arg__1)

If arg__1 is true, sets fixed pitch on; otherwise sets fixed pitch off.

See Also:
fixedPitch, QFontInfo

setItalic

public final void setItalic(boolean b)

Sets the style of the font to QFont::StyleItalic if b is true; otherwise the style is set to QFont::StyleNormal.

See Also:
italic, QFontInfo

setKerning

public final void setKerning(boolean arg__1)

Enables kerning for this font if arg__1 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, QFontMetrics

setOverline

public final void setOverline(boolean arg__1)

If arg__1 is true, sets overline on; otherwise sets overline off.

See Also:
overline, QFontInfo

setPixelSize

public final void setPixelSize(int arg__1)

Sets the font size to arg__1 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 arg__1. The point size must be greater than zero.

See Also:
pointSize, setPointSizeF

setPointSizeF

public final void setPointSizeF(double arg__1)

Sets the point size to arg__1. The point size must be greater than zero. The requested precision may not be achieved on all platforms.

See Also:
pointSizeF, setPointSize, setPixelSize

setRawMode

public final void setRawMode(boolean arg__1)

If arg__1 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, 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 arg__1 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 arg__1 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, 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 arg__1 percent. For example, setting arg__1 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.

See Also:
stretch, QFont::Stretch

setStrikeOut

public final void setStrikeOut(boolean arg__1)

If arg__1 is true, sets strikeout on; otherwise sets strikeout off.

See Also:
strikeOut, QFontInfo

setStyle

public final void setStyle(QFont.Style style)

Sets the style of the font to style.

See Also:
style, italic, QFontInfo

setStyleHint

public final void setStyleHint(QFont.StyleHint arg__1)

Equivalent to setStyleHint(arg__1, PreferDefault).


setStyleHint

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

Sets the style hint and strategy to arg__1 and arg__2, 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, QFontInfo

setStyleStrategy

public final void setStyleStrategy(QFont.StyleStrategy s)

Sets the style strategy for the font to s.

See Also:
styleStrategy, QFont::StyleStrategy

public final void setUnderline(boolean arg__1)

If arg__1 is true, sets underline on; otherwise sets underline off.

See Also:
underline, QFontInfo

setWeight
