Struct QStyleOptionComboBox

#[repr(C)]
pub struct QStyleOptionComboBox { /* private fields */ }

The QStyleOptionComboBox class is used to describe the parameter for drawing a combobox.

C++ class: QStyleOptionComboBox.

C++ documentation:

The QStyleOptionComboBox class is used to describe the parameter for drawing a combobox.

QStyleOptionButton contains all the information that QStyle functions need to draw QComboBox.

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.

For an example demonstrating how style options can be used, see the Styles example.

C++ documentation:

The QStyleOptionComplex class is used to hold parameters that are common to all complex controls.

This class is not used on its own. Instead it is used to derive other complex control options, for example QStyleOptionSlider and QStyleOptionSpinBox.
