| 50 | \class QStyleOption |
| 51 | \brief The QStyleOption class stores the parameters used by QStyle functions. |
| 52 | |
| 53 | \ingroup appearance |
| 54 | \inmodule QtWidgets |
| 55 | |
| 56 | QStyleOption and its subclasses contain all the information that |
| 57 | QStyle functions need to draw a graphical element. |
| 58 | |
| 59 | For performance reasons, there are few member functions and the |
| 60 | access to the member variables is direct (i.e., using the \c . or |
| 61 | \c -> operator). This makes the structures straightforward to use |
| 62 | and emphasizes that these are simply parameters used by the style |
| 63 | functions. |
| 64 | |
| 65 | The caller of a QStyle function usually creates QStyleOption |
| 66 | objects on the stack. This combined with Qt's extensive use of |
| 67 | \l{implicit sharing} for types such as QString, QPalette, and |
| 68 | QColor ensures that no memory allocation needlessly takes place. |
| 69 | |
| 70 | The following code snippet shows how to use a specific |
| 71 | QStyleOption subclass to paint a push button: |
| 72 | |
| 73 | \snippet qstyleoption/main.cpp 0 |
| 74 | |
| 75 | In our example, the control is a QStyle::CE_PushButton, and |
| 76 | according to the QStyle::drawControl() documentation the |
| 77 | corresponding class is QStyleOptionButton. |
| 78 | |
| 79 | When reimplementing QStyle functions that take a QStyleOption |
| 80 | parameter, you often need to cast the QStyleOption to a subclass. |
| 81 | For safety, you can use qstyleoption_cast() to ensure that the |
| 82 | pointer type is correct. For example: |
| 83 | |
| 84 | \snippet qstyleoption/main.cpp 4 |
| 85 | |
| 86 | The qstyleoption_cast() function will return 0 if the object to |
| 87 | which \c option points is not of the correct type. |
| 88 | |
| 89 | For an example demonstrating how style options can be used, see |
| 90 | the \l {widgets/styles}{Styles} example. |
