pyqt4如何导入和更改绘制文本的自定义字体

Question

我绘制文本，问题是如何导入自定义字体（tff 文件与脚本文件位于同一文件夹中）并更改字体。这是代码：

def paintEvent(self, e):
    painter = QtGui.QPainter(self)
    painter.setRenderHint(painter.Antialiasing)

    self.drawText(e, painter)

    super(SpeedPrg, self).paintEvent(e)

def drawText(self, event, qp):

    qp.setPen(QtGui.QColor(255,255,255))
    qp.drawText(event.rect(), QtCore.Qt.AlignCenter, str(self.setText))

Answer 1

您将使用这样的代码：

# Load the font: 
font_db = QFontDatabase()
font_id = font_db.addApplicationFont("your_font.ttf")
# families = font_db.applicationFontFamilies(font_id)
your_ttf_font = QFont("one of your font families")

# tell painter to use your font: 
qp.setFont(your_ttf_font)
