PySide.QtGui.QFontDialog class provides a dialog widget for selecting a font.
字体对话框的创建是透过某一静态 PySide.QtGui.QFontDialog.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.
