QStyleOptionViewItemclass is used to describe the parameters used to draw an item in a view widget. 更多 …
QStyleOptionViewItemcontains all the information thatQStylefunctions need to draw the items for Qt’s model/view classes.For performance reasons, the access to the member variables is direct (i.e., using the
.or->operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.对于可以如何使用样式选项的演示范例,见 样式 范例。
