QPicture QLabel:: picture ( Qt::ReturnByValueConstant ) const

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

Use the overload without argument instead.

返迴標簽的圖片。

先前，Qt 提供版本的 picture() which returned the picture by-pointer. That version is now removed. This overload allowed to explicitly differentiate between the by-pointer function and the by-value.

QPixmap QLabel:: pixmap ( Qt::ReturnByValueConstant ) const

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

Use the overload without argument instead.

Returns the label's pixmap.

先前，Qt 提供版本的 pixmap() which returned the pixmap by-pointer. That version has now been removed. This overload allowed to explicitly differentiate between the by-pointer function and the by-value.

QPixmap pixmapVal = label->pixmap(Qt::ReturnByValue);
