QStyleOptionHeaderclass is used to describe the parameters for drawing a header. 更多 …
QStyleOptionHeadercontains all the information thatQStylefunctions need to draw the item views’ header pane, header sort arrow, and header label.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。
