Creates a font database object.
Loads the font from the file specified by fileName and makes it available to the application. An ID is returned that can be used to remove the font again with removeApplicationFont() or to retrieve the list of family names contained in the font.
The function returns -1 if the font could not be loaded.
Currently only TrueType fonts, TrueType font collections, and OpenType fonts are supported.
Note: Adding application fonts on Unix/X11 platforms without fontconfig is currently not supported.
Эта функция была введена в Qt 4.2.
See also addApplicationFontFromData(), applicationFontFamilies(), and removeApplicationFont().
Loads the font from binary data specified by fontData and makes it available to the application. An ID is returned that can be used to remove the font again with removeApplicationFont() or to retrieve the list of family names contained in the font.
The function returns -1 if the font could not be loaded.
Currently only TrueType fonts and TrueType font collections are supported.
Note: Adding application fonts on Unix/X11 platforms without fontconfig is currently not supported.
Эта функция была введена в Qt 4.2.
See also addApplicationFont(), applicationFontFamilies(), and removeApplicationFont().
Returns a list of font families for the given application font identified by id.
Эта функция была введена в Qt 4.2.
See also addApplicationFont() and addApplicationFontFromData().
Returns true if the font that has family family and style style is bold; otherwise returns false.
See also italic() and weight().
Returns a sorted list of the available font families which support the writingSystem.
If a family exists in several foundries, the returned name for that font is in the form "family [foundry]". Examples: "Times [Adobe]", "Times [Cronyx]", "Palatino".
See also writingSystems().
Returns a QFont object that has family family, style style and point size pointSize. If no matching font could be created, a QFont object that uses the application's default font is returned.
Returns true if the font that has family family and style style is a scalable bitmap font; otherwise returns false. Scaling a bitmap font usually produces an unattractive hardly readable result, because the pixels of the font are scaled. If you need to scale a bitmap font it is better to scale it to one of the fixed sizes returned by smoothSizes().
See also isScalable() and isSmoothlyScalable().
Returns true if the font that has family family and style style is fixed pitch; otherwise returns false.
Returns true if the font that has family family and style style is scalable; otherwise returns false.
See also isBitmapScalable() and isSmoothlyScalable().
Returns true if the font that has family family and style style is smoothly scalable; otherwise returns false. If this function returns true, it's safe to scale this font to any size, and the result will always look attractive.
See also isScalable() and isBitmapScalable().
Returns true if the font that has family family and style style is italic; otherwise returns false.
Returns a list of the point sizes available for the font that has family family and style style. The list may be empty.
See also smoothSizes() and standardSizes().
Removes all application-local fonts previously added using addApplicationFont() and addApplicationFontFromData().
Returns true if unloading of the fonts succeeded; otherwise returns false.
Эта функция была введена в Qt 4.2.
See also removeApplicationFont(), addApplicationFont(), and addApplicationFontFromData().
Removes the previously loaded application font identified by id. Returns true if unloading of the font succeeded; otherwise returns false.
Эта функция была введена в Qt 4.2.
See also removeAllApplicationFonts(), addApplicationFont(), and addApplicationFontFromData().
Returns the point sizes of a font that has family family and style style that will look attractive. The list may be empty. For non-scalable fonts and bitmap scalable fonts, this function is equivalent to pointSizes().
See also pointSizes() and standardSizes().
Returns a list of standard font sizes.
See also smoothSizes() and pointSizes().
Returns a string that describes the style of the font. For example, "Bold Italic", "Bold", "Italic" or "Normal". An empty string may be returned.
Returns a string that describes the style of the fontInfo. For example, "Bold Italic", "Bold", "Italic" or "Normal". An empty string may be returned.
Returns a list of the styles available for the font family family. Some example styles: "Light", "Light Italic", "Bold", "Oblique", "Demi". The list may be empty.
See also families().
Returns true if font rendering is supported outside the GUI thread, false otherwise. In other words, a return value of false means that all QPainter::drawText() calls outside the GUI thread will not produce readable output.
Эта функция была введена в Qt 4.4.
See also threads.html#painting-in-threads.
Returns the weight of the font that has family family and style style. If there is no such family and style combination, returns -1.
Returns the names the writingSystem (e.g. for displaying to the user in a dialog).
Returns a string with sample characters from writingSystem.
Returns a sorted list of the available writing systems. This is list generated from information about all installed fonts on the system.
See also families().
Returns a sorted list of the writing systems supported by a given font family.
See also families().
