QFontDialog ¶

概要 ¶

详细描述 ¶

字体对话框的创建是透过某一静态 getFont() 函数。

范例：

(ok, font) = QFontDialog.getFont(QFont("Helvetica [Cronyx]", 10), self)
if ok:
    # the user clicked OK and font is set to the font the user selected
else:
    # the user canceled the dialog; font is set to the initial
    # value, in this case Helvetica [Cronyx], 10
											

The dialog can also be used to set a widget’s font directly:

myWidget.setFont(QFontDialog.getFont(0, myWidget.font()))
											

If the user clicks OK the font they chose will be used for myWidget, and if they click Cancel the original font is used.
