The QStyleOption class specifies optional parameters for QStyle functions.
Some QStyle functions take an optional argument specifying extra information that is required for a paritical primitive or control. So that the QStyle class can be extended, QStyleOption is used to provide a variable-argument for these options.
The QStyleOption class has constructors for each type of optional argument, and this set of constructors may be extended in future Qt releases. There are also corresponding access functions that return the optional arguments: these too may be extended.
For each constructor, you should refer to the documentation of the QStyle functions to see the meaning of the arguments.
When calling QStyle functions from your own widgets, you must only pass the default QStyleOption or the argument that QStyle is documented to accept. For example, if the function expects QStyleOption(QMenuItem *, int), passing QStyleOption(QMenuItem *) leaves the optional integer argument uninitialized.
When subclassing QStyle, you must similarly only expect the default or documented arguments. The other arguments will have uninitialized values.
If you make your own QStyle subclasses and your own widgets, you can make a subclass of QStyleOption to pass additional arguments to your QStyle subclass. You will need to cast the "const QStyleOption&" argument to your subclass, so be sure your style has been called from your widget.
This enum value can be passed as the optional argument to any QStyle function.
Default
| QStyleOption::QStyleOption | ( | StyleOptionDefault | = Default | ) | [inline] |
The default option. This can always be passed as the optional argument to QStyle functions.
| QStyleOption::QStyleOption | ( | int | in1 | ) | [inline] |

Pass two integers, in1 and in2. For example, linewidth and midlinewidth.
Pass four integers, in1, in2, in3 and in4.
| QStyleOption::QStyleOption | ( | QMenuItem * | m | ) | [inline] |
