[since 5.1] QSize QIcon:: actualSize ( QWindow * window , const QSize & size , QIcon::Mode mode = Normal, QIcon::State state = Off) const

This function is deprecated since 6.0. We strongly advise against using it in new code.

Use actualSize(size) instead.

Returns the actual size of the icon for the requested window size , mode ，和 state .

The pixmap can be smaller than the requested size. The returned size is in device-independent pixels (This is relevant for high-dpi pixmaps.)

该函数在 Qt 5.1 引入。

[since 5.1] QPixmap QIcon:: pixmap ( QWindow * window , const QSize & size , QIcon::Mode mode = Normal, QIcon::State state = Off) const

This function is deprecated since 6.0. We strongly advise against using it in new code.

Use pixmap(size, devicePixelRatio) instead.

Returns a pixmap with the requested window size , mode ，和 state , generating one if necessary.

The pixmap can be smaller than the requested size. If window is on a high-dpi display the pixmap can be larger. In that case it will have a devicePixelRatio larger than 1.

该函数在 Qt 5.1 引入。
