80 QFontDef comparison is more complicated than just simple-
81 per-member comparisons.-
82-
83 When comparing point/pixel sizes, either point or pixelsize-
84 could be -1. in This case we have to compare the non negative-
85 size value.-
86-
87 This test will fail if the point-sizes differ by 1/2 point or-
88 more or they do not round to the same value. We have to do this-
89 since our API still uses 'int' point-sizes in the API, but store-
90 deci-point-sizes internally.-
91-
92 To compare the family members, we need to parse the font names-
93 and compare the family/foundry strings separately. This allows-
94 us to compare e.g. "Helvetica" and "Helvetica [Adobe]" with-
95 positive results.-

349 When you create a QFont object you specify various attributes that-
350 you want the font to have. Qt will use the font with the specified-
351 attributes, or if no matching font exists, Qt will use the closest-
352 matching installed font. The attributes of the font that is-
353 actually used are retrievable from a QFontInfo object. If the-
354 window system provides an exact match exactMatch() returns \c true.-
355 Use QFontMetrics to get measurements, e.g. the pixel length of a-
356 string using QFontMetrics::width().-
357-
358 Note that a QGuiApplication instance must exist before a QFont can be-
359 used. You can set the application's default font with-
360 QGuiApplication::setFont().-
361-
362 If a chosen font does not include all the characters that-
363 need to be displayed, QFont will try to find the characters in the-
364 nearest equivalent fonts. When a QPainter draws a character from a-
365 font the QFont will report whether or not it has the character; if-
366 it does not, QPainter will draw an unfilled square.-
367-
368 Create QFonts like this:-
369-
370 \snippet code/src_gui_text_qfont.cpp 0-
371-
372 The attributes set in the constructor can also be set later, e.g.-
373 setFamily(), setPointSize(), setPointSizeF(), setWeight() and-
374 setItalic(). The remaining attributes must be set after-
375 contstruction, e.g. setBold(), setUnderline(), setOverline(),-
376 setStrikeOut() and setFixedPitch(). QFontInfo objects should be-
377 created \e after the font's attributes have been set. A QFontInfo-
378 object will not change, even if you change the font's-
379 attributes. The corresponding "get" functions, e.g. family(),-
380 pointSize(), etc., return the values that were set, even though-
381 the values used may differ. The actual values are available from a-
382 QFontInfo object.-
383-
384 If the requested font family is unavailable you can influence the-
385 \l{#fontmatching}{font matching algorithm} by choosing a-
386 particular \l{QFont::StyleHint} and \l{QFont::StyleStrategy} with-
387 setStyleHint(). The default family (corresponding to the current-
388 style hint) is returned by defaultFamily().-
389-
390 The font-matching algorithm has a lastResortFamily() and-
391 lastResortFont() in cases where a suitable match cannot be found.-
392 You can provide substitutions for font family names using-
393 insertSubstitution() and insertSubstitutions(). Substitutions can-
394 be removed with removeSubstitutions(). Use substitute() to retrieve-
395 a family's first substitute, or the family name itself if it has-
396 no substitutes. Use substitutes() to retrieve a list of a family's-
397 substitutes (which may be empty).-
398-
399 Every QFont has a key() which you can use, for example, as the key-
400 in a cache or dictionary. If you want to store a user's font-
401 preferences you could use QSettings, writing the font information-
402 with toString() and reading it back with fromString(). The-
403 operator<<() and operator>>() functions are also available, but-
404 they work on a data stream.-
405-
406 It is possible to set the height of characters shown on the screen-
407 to a specified number of pixels with setPixelSize(); however using-
408 setPointSize() has a similar effect and provides device-
409 independence.-
410-
411 Loading fonts can be expensive, especially on X11. QFont contains-
412 extensive optimizations to make the copying of QFont objects fast,-
413 and to cache the results of the slow window system functions it-
414 depends upon.-
415-
416 \target fontmatching-
417 The font matching algorithm works as follows:-
418 \list 1-
419 \li The specified font family is searched for.-
420 \li If not found, the styleHint() is used to select a replacement-
421 family.-
422 \li Each replacement font family is searched for.-
423 \li If none of these are found or there was no styleHint(), "helvetica"-
424 will be searched for.-
425 \li If "helvetica" isn't found Qt will try the lastResortFamily().-
426 \li If the lastResortFamily() isn't found Qt will try the-
427 lastResortFont() which will always return a name of some kind.-
428 \endlist-
429-
430 Note that the actual font matching algorithm varies from platform to platform.-
431-
432 In Windows a request for the "Courier" font is automatically changed to-
433 "Courier New", an improved version of Courier that allows for smooth scaling.-
434 The older "Courier" bitmap font can be selected by setting the PreferBitmap-
435 style strategy (see setStyleStrategy()).-
436-
437 Once a font is found, the remaining attributes are matched in order of-
438 priority:-
439 \list 1-
440 \li fixedPitch()-
441 \li pointSize() (see below)-
442 \li weight()-
443 \li style()-
444 \endlist-
445-
446 If you have a font which matches on family, even if none of the-
447 other attributes match, this font will be chosen in preference to-
448 a font which doesn't match on family but which does match on the-
449 other attributes. This is because font family is the dominant-
450 search criteria.-
451-
452 The point size is defined to match if it is within 20% of the-
453 requested point size. When several fonts match and are only-
454 distinguished by point size, the font with the closest point size-
455 to the one requested will be chosen.-
456-
457 The actual family, font size, weight and other font attributes-
458 used for drawing text will depend on what's available for the-
459 chosen family under the window system. A QFontInfo object can be-
460 used to determine the actual values used for drawing the text.-
461-
462 Examples:-
463-
464 \snippet code/src_gui_text_qfont.cpp 1-
465 If you had both an Adobe and a Cronyx Helvetica, you might get-
466 either.-
467-
468 \snippet code/src_gui_text_qfont.cpp 2-
469-
470 You can specify the foundry you want in the family name. The font f-
471 in the above example will be set to "Helvetica-
472 [Cronyx]".-
473-
474 To determine the attributes of the font actually used in the window-
475 system, use a QFontInfo object, e.g.-
476-
477 \snippet code/src_gui_text_qfont.cpp 3-
478-
479 To find out font metrics use a QFontMetrics object, e.g.-
480-
481 \snippet code/src_gui_text_qfont.cpp 4-

782 scalable, using the same metrics as are used e.g. when printing.-
783 \value PreferVerticalHinting If possible, render text with no horizontal hinting,-
784 but align glyphs to the pixel grid in the vertical direction. The text will appear-
785 crisper on displays where the density is too low to give an accurate rendering-
786 of the glyphs. But since the horizontal metrics of the glyphs are unhinted, the text's-
787 layout will be scalable to higher density devices (such as printers) without impacting-
788 details such as line breaks.-
789 \value PreferFullHinting If possible, render text with hinting in both horizontal and-
790 vertical directions. The text will be altered to optimize legibility on the target-
791 device, but since the metrics will depend on the target size of the text, the positions-
792 of glyphs, line breaks, and other typographical detail will not scale, meaning that a-
793 text layout may look different on devices with different pixel densities.-

2333 \class QFontInfo-
2334 \reentrant-
2335-
2336 \brief The QFontInfo class provides general information about fonts.-
2337 \inmodule QtGui-
2338-
2339 \ingroup appearance-
2340 \ingroup shared-
2341-
2342 The QFontInfo class provides the same access functions as QFont,-
2343 e.g. family(), pointSize(), italic(), weight(), fixedPitch(),-
2344 styleHint() etc. But whilst the QFont access functions return the-
2345 values that were set, a QFontInfo object returns the values that-
2346 apply to the font that will actually be used to draw the text.-
2347-
2348 For example, when the program asks for a 25pt Courier font on a-
2349 machine that has a non-scalable 24pt Courier font, QFont will-
2350 (normally) use the 24pt Courier for rendering. In this case,-
2351 QFont::pointSize() returns 25 and QFontInfo::pointSize() returns-
2352 24.-
2353-
2354 There are three ways to create a QFontInfo object.-
2355 \list 1-
2356 \li Calling the QFontInfo constructor with a QFont creates a font-
2357 info object for a screen-compatible font, i.e. the font cannot be-
2358 a printer font. If the font is changed later, the font-
2359 info object is \e not updated.-
2360-
2361 (Note: If you use a printer font the values returned may be-
2362 inaccurate. Printer fonts are not always accessible so the nearest-
2363 screen font is used if a printer font is supplied.)-
2364-
2365 \li QWidget::fontInfo() returns the font info for a widget's font.-
2366 This is equivalent to calling QFontInfo(widget->font()). If the-
2367 widget's font is changed later, the font info object is \e not-
2368 updated.-
2369-
2370 \li QPainter::fontInfo() returns the font info for a painter's-
2371 current font. If the painter's font is changed later, the font-
2372 info object is \e not updated.-
2373 \endlist-

2382 drawing text in \l{QWidget}{widgets} or \l{QPixmap}{pixmaps}, not QPicture or QPrinter.-
2383-
2384 The font info object holds the information for the font that is-
2385 passed in the constructor at the time it is created, and is not-
2386 updated if the font's attributes are changed later.-
2387-
2388 Use QPainter::fontInfo() to get the font info when painting.-
2389 This will give correct results also when painting on paint device-
2390 that is not screen-compatible.-
