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 | - |
