#include <qfont.h>
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 choosen X11 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:
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 the X Window System 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.
fontmatching The font matching algorithm works as follows: 1 The specified font family is searched for. If not found, the styleHint() is used to select a replacement family. Each replacement font family is searched for. If none of these are found or there was no styleHint(), "helvetica" will be searched for. If "helvetica" isn't found Qt will try the lastResortFamily(). If the lastResortFamily() isn't found Qt will try the lastResortFont() which will always return a name of some kind.
Once a font is found, the remaining attributes are matched in order of priority: 1 fixedPitch() pointSize() (see below) weight() italic()
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.
You can specify the foundry you want in the family name. Both fonts, f1 and f2, 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.
To find out font metrics use a QFontMetrics object, e.g.
QFontMetrics fm( f1 ); int pixelWidth = fm.width( "How many pixels wide is this text?" ); int pixelHeight = fm.height();
For more general information on fonts, see the comp.fonts FAQ. Information on encodings can be found from Roman Czyborra's page.

| enum QFont::StyleHint |
Style hints are used by the font matching algorithm to find an appropriate default family if a selected font family is not available.
AnyStyle leaves the font matching algorithm to choose the family. This is the default.
SansSerif the font matcher prefer sans serif fonts. Helvetica is a synonym for SansSerif.
Serif the font matcher prefers serif fonts. Times is a synonym for Serif.
TypeWriter the font matcher prefers fixed pitch fonts. Courier a synonym for TypeWriter.
OldEnglish the font matcher prefers decorative fonts. Decorative is a synonym for OldEnglish.
System the font matcher prefers system fonts.
| enum QFont::StyleHint |
| enum QFont::StyleStrategy |
The style strategy tells the font matching algorithm what type of fonts should be used to find an appropriate default family.
The following strategies are available:
PreferDefault the default style strategy. It does not prefer any type of font. PreferBitmap prefers bitmap fonts (as opposed to outline fonts). PreferDevice prefers device fonts. PreferOutline prefers outline fonts (as opposed to bitmap fonts). ForceOutline forces the use of outline fonts. NoAntialias don't antialias the fonts. PreferAntialias antialias if possible. OpenGLCompatible forces the use of OpenGL compatible fonts.
Any of these may be OR-ed with one of these flags:
PreferMatch prefer an exact match. The font matcher will try to use the exact font size that has been specified. PreferQuality prefer the best quality font. The font matcher will use the nearest standard point size that the font supports.
| enum QFont::StyleStrategy |
| enum QFont::Weight |
Qt uses a weighting scale from 0 to 99 similar to, but not the same as, the scales used in Windows or CSS. A weight of 0 is ultralight, whilst 99 will be an extremely black.
This enum contains the predefined font weights:
Light 25 Normal 50 DemiBold 63 Bold 75 Black 87
| enum QFont::Weight |

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.

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 a null string is returned.
| QString QFont::lastResortFamily | ( | ) | const |
| QString QFont::lastResortFont | ( | ) | const |
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.
| QString QFont::lastResortFont | ( | ) | const |
Returns TRUE if this font is different from f; otherwise returns FALSE.

| bool QFont::rawMode | ( | ) | const |
| bool QFont::rawMode | ( | ) | const |
Returns TRUE if raw mode is used for font name matching; otherwise returns FALSE.
| QString QFont::rawName | ( | ) | const |
Returns the name of the font within the underlying window system.
On Windows, this is usually just the family name of a TrueType font.
On X11, it is an XLFD (X Logical Font Description). When Qt is build with Xft support on X11, the return value can be an Xft pattern or an XLFD.
Using the return value of this function is usually not portable.
| QString QFont::rawName | ( | ) | const |
| void QFont::removeSubstitution | ( | const QString & | familyName | ) | [static] |
Removes all the substitutions for familyName.
| static void QFont::removeSubstitution | ( | const QString & | ) | [static] |
Returns a new QFont that has attributes copied from other.
| void QFont::setBold | ( | bool | enable | ) | [inline] |
If enable is true sets the font's weight to QFont::Bold ; otherwise sets the weight to QFont::Normal.
For finer boldness control use setWeight().
| void QFont::setBold | ( | bool | ) |
| static void QFont::setDefaultFont | ( | const QFont & | ) | [static] |
| void QFont::setDefaultFont | ( | const QFont & | f | ) | [static] |
Please use QApplication::setFont() instead.
| void QFont::setFamily | ( | const QString & | family | ) |
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]". (The Qt 2.x syntax, i.e. "Cronyx-Helvetica", is also supported.) 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.
| void QFont::setFamily | ( | const QString & | ) |
| void QFont::setFixedPitch | ( | bool | ) |
| void QFont::setFixedPitch | ( | bool | enable | ) |
If enable is TRUE, sets fixed pitch on; otherwise sets fixed pitch off.
| void QFont::setItalic | ( | bool | ) |
| void QFont::setItalic | ( | bool | enable | ) |
| void QFont::setOverline | ( | bool | ) |
| void QFont::setOverline | ( | bool | enable | ) |
If enable is TRUE, sets overline on; otherwise sets overline off.
| void QFont::setPixelSize | ( | int | pixelSize | ) |
Sets the font size to pixelSize pixels.
Using this function makes the font device dependent. Use setPointSize() or setPointSizeFloat() to set the size of the font in a device independent manner.
| void QFont::setPixelSize | ( | int | ) |
| void QFont::setPixelSizeFloat | ( | float | ) |
| void QFont::setPixelSizeFloat | ( | float | pixelSize | ) |
Sets the logical pixel height of font characters when shown on the screen to pixelSize.
| void QFont::setPointSize | ( | int | ) |
| void QFont::setPointSize | ( | int | pointSize | ) |
Sets the point size to pointSize. The point size must be greater than zero.
| void QFont::setPointSizeFloat | ( | float | ) |
| void QFont::setPointSizeFloat | ( | float | pointSize | ) |
Sets the point size to pointSize. The point size must be greater than zero. The requested precision may not be achieved on all platforms.
| void QFont::setRawMode | ( | bool | ) |
| void QFont::setRawMode | ( | bool | enable | ) |
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).
| void QFont::setRawName | ( | const QString & | name | ) |
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.
| void QFont::setRawName | ( | const QString & | ) |
| void QFont::setStretch | ( | int | ) |
| void QFont::setStretch | ( | int | factor | ) |
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.
| void QFont::setStrikeOut | ( | bool | ) |
| void QFont::setStrikeOut | ( | bool | enable | ) |
If enable is TRUE, sets strikeout on; otherwise sets strikeout off.
| void QFont::setStyleHint | ( | StyleHint | , |
| StyleStrategy | = PreferDefault |
||
| ) |
| void QFont::setStyleHint | ( | StyleHint | hint, |
| StyleStrategy | strategy = PreferDefault |
||
| ) |
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.
| void QFont::setStyleStrategy | ( | StyleStrategy | s | ) |
| void QFont::setStyleStrategy | ( | StyleStrategy | s | ) |
Sets the style strategy for the font to s.
| void QFont::setUnderline | ( | bool | enable | ) |
If enable is TRUE, sets underline on; otherwise sets underline off.
| void QFont::setUnderline | ( | bool | ) |
| void QFont::setWeight | ( | int | ) |
| void QFont::setWeight | ( | int | weight | ) |
Sets the weight the font to weight, which should be a value from the QFont::Weight enumeration.
| int QFont::stretch | ( | ) | const |
| int QFont::stretch | ( | ) | const |
Returns the stretch factor for the font.
| bool QFont::strikeOut | ( | ) | const |

The style hint affects the font matching algorithm. See QFont::StyleHint for the list of strategies.
| StyleStrategy QFont::styleStrategy | ( | ) | const |
| QFont::StyleStrategy QFont::styleStrategy | ( | ) | const |
Returns the StyleStrategy.
The style strategy affects the font matching algorithm. See QFont::StyleStrategy for the list of strategies.
Returns the first family name to be used whenever familyName is specified. The lookup is case insensitive.
If there is no substitution for familyName, familyName is returned.
To obtain a list of substitutions use substitutes().
| static QStringList QFont::substitutes | ( | const QString & | ) | [static] |
| QStringList QFont::substitutes | ( | const QString & | familyName | ) | [static] |
Returns a list of family names to be used whenever familyName is specified. The lookup is case insensitive.
