linux - qt-embedded-linux绘图库是定点的吗？

Question

我正在开发没有浮点单元的嵌入式设备，我想将 QT-embedded-linux 移植到它。所以请告诉我qt的绘图库是否有定点？

谢谢，桑尼。

As far as I've used Qt the only floating-point-heavy parts were The Graphics View Framework and QtOpenGL module. Other parts related to graphics mainly used integers, though internally there might be some parts where floating-point arithmetic is used. You should probably have a short look at the source of parts you wanna use.
