290 \class QFontComboBox -
291 \brief The QFontComboBox widget is a combobox that lets the user -
292 select a font family. -
293 -
294 \since 4.2 -
295 \ingroup basicwidgets -
296 \inmodule QtWidgets -
297 -
298 The combobox is populated with an alphabetized list of font -
299 family names, such as Arial, Helvetica, and Times New Roman. -
300 Family names are displayed using the actual font when possible. -
301 For fonts such as Symbol, where the name is not representable in -
302 the font itself, a sample of the font is displayed next to the -
303 family name. -
304 -
305 QFontComboBox is often used in toolbars, in conjunction with a -
306 QComboBox for controlling the font size and two \l{QToolButton}s -
307 for bold and italic. -
308 -
309 When the user selects a new font, the currentFontChanged() signal -
310 is emitted in addition to currentIndexChanged(). -
311 -
312 Call setWritingSystem() to tell QFontComboBox to show only fonts -
313 that support a given writing system, and setFontFilters() to -
314 filter out certain types of fonts as e.g. non scalable fonts or -
315 monospaced fonts. -
