1356 \class QFontDatabase-
1357 \threadsafe-

1359-
1360 \brief The QFontDatabase class provides information about the fonts available in the underlying window system.-
1361-
1362 \ingroup appearance-
1363-
1364 The most common uses of this class are to query the database for-
1365 the list of font families() and for the pointSizes() and styles()-
1366 that are available for each family. An alternative to pointSizes()-
1367 is smoothSizes() which returns the sizes at which a given family-
1368 and style will look attractive.-
1369-
1370 If the font family is available from two or more foundries the-
1371 foundry name is included in the family name; for example:-
1372 "Helvetica [Adobe]" and "Helvetica [Cronyx]". When you specify a-
1373 family, you can either use the old hyphenated "foundry-family"-
1374 format or the bracketed "family [foundry]" format; for example:-
1375 "Cronyx-Helvetica" or "Helvetica [Cronyx]". If the family has a-
1376 foundry it is always returned using the bracketed format, as is-
1377 the case with the value returned by families().-
1378-
1379 The font() function returns a QFont given a family, style and-
1380 point size.-
1381-
1382 A family and style combination can be checked to see if it is-
1383 italic() or bold(), and to retrieve its weight(). Similarly we can-
1384 call isBitmapScalable(), isSmoothlyScalable(), isScalable() and-
1385 isFixedPitch().-
1386-
1387 Use the styleString() to obtain a text version of a style.-
1388-
1389 The QFontDatabase class also supports some static functions, for-
1390 example, standardSizes(). You can retrieve the description of a-
1391 writing system using writingSystemName(), and a sample of-
1392 characters in a writing system with writingSystemSample().-
1393-
1394 Example:-
1395-
1396 \snippet qfontdatabase/main.cpp 0-
1397 \snippet qfontdatabase/main.cpp 1-
1398-
1399 This example gets the list of font families, the list of-
1400 styles for each family, and the point sizes that are available for-
1401 each combination of family and style, displaying this information-
1402 in a tree view.-
