Struct qt_widgets::QStyleOptionComboBox

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

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.

Methods from Deref<Target = QStyleOptionComplex>

pub unsafe fn active_sub_controls(&self) -> QFlags<SubControl>

Returns a reference to the activeSubControls field.

pub unsafe fn copy_from(
    &mut self,
    other: impl CastInto<Ref<QStyleOptionComplex>>
) -> MutRef<QStyleOptionComplex>

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

Calls C++ function: QStyleOptionComplex& QStyleOptionComplex::operator=(const QStyleOptionComplex& other).

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.

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator).

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

pub unsafe fn set_active_sub_controls(&mut self, value: QFlags<SubControl>)
