[−][src]Struct qt_widgets::q_style_option_combo_box::StyleOptionVersion
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.
C++ enum: QStyleOptionComboBox::StyleOptionVersion
.
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.
The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally do not need to check it.
