详细描述

The QFontComboBox widget is a combobox that lets the user select a font family.

The combobox is populated with an alphabetized list of font family names, such as Arial, Helvetica, and Times New Roman. Family names are displayed using the actual font when possible. For fonts such as Symbol, where the name is not representable in the font itself, a sample of the font is displayed next to the family name.

QFontComboBox is often used in toolbars, in conjunction with a QComboBox for controlling the font size and two QToolButton s for bold and italic.

When the user selects a new font, the currentFontChanged () signal is emitted in addition to currentIndexChanged ().

调用 setWritingSystem () 到 tell QFontComboBox to show only fonts that support a given writing system, and setFontFilters () 到 filter out certain types of fonts as e.g. non scalable fonts or monospaced fonts.

QFontComboBox.FontFilter

This enum can be used to only show certain types of fonts in the font combo box.

常量	值	描述
`QFontComboBox.AllFonts`	`0`	Show all fonts
`QFontComboBox.ScalableFonts`	`0x1`	Show scalable fonts
`QFontComboBox.NonScalableFonts`	`0x2`	Show non scalable fonts
`QFontComboBox.MonospacedFonts`	`0x4`	Show monospaced fonts
`QFontComboBox.ProportionalFonts`	`0x8`	Show proportional fonts

The FontFilters type is a typedef for QFlags <FontFilter>. It stores an OR combination of FontFilter values.
