Qt widget to display LaTeX

[Gunnar G]

Hi.
Since you are using Qt for LyX, I wonder, is there an easy way of using a
(hopefully small) part of the LyX code to display LaTeX math formulas
nicely in a ordinary Qt program?

Something like:
QLyXWidget* myWidget = new QLyXWidget("\\frac{3+x}{xy});

would be great.
