matplotlib - 在Qt表单上写TeX

Question

我想在我的Qt表单中添加一些TeX文本,比如标签 - 只是文本,没有图表,没有行,没有边框,只有TeX.我想到这样的事情:将TeX渲染为位图,然后将该位图放在窗体上,例如放入QLabel.甚至更好 - 使用一些后端,将其添加到表单并使用某些东西tex_label.print_tex(<tex code>).似乎matplotplot有TeX解析器,但我无法弄清楚如何使用它们......

谢谢.

作为变种:

    from matplotlib.figure import Figure
    from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg

    # Get window background color
    bg = self.palette().window().color()
    cl = (bg.redF(), bg.greenF(), bg.blueF())

    # Create figure, using window bg color
    self.fig = Figure(edgecolor=cl, facecolor=cl)

    # Add FigureCanvasQTAgg widget to form
    self.canvas = FigureCanvasQTAgg(self.fig)        
    self.tex_label_placeholder.layout().addWidget(self.canvas)

    # Clear figure
    self.fig.clear()

    # Set figure title
    self.fig.suptitle('$TeX$',
                      x=0.0, y=0.5, 
                      horizontalalignment='left',
                      verticalalignment='center')
    self.canvas.draw()
