Detailed Description▲
QStyleOptionToolButton contains all the information that QStyle functions need to draw QToolButton.
For performance reasons, there are few member functions and the access to the member variables is direct (i.e., using the . or -> operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
For an example demonstrating how style options can be used, see the Styles example.
