詳細描述

The QStyleOptionSpinBox class is used to describe the parameters necessary for drawing a spin box.

QStyleOptionSpinBox contains all the information that QStyle 函數需要繪製 QSpinBox and QDateTimeEdit .

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.
