Create
A static factory method that allocates and initializes an slider control.
Declaration
static OSSharedPtr<IOUserVideoSliderControl> Create(IOUserVideoDriver *in_driver, bool in_is_settable, uint32_t in_control_value, IOUserVideoSliderRange in_range, IOUserVideoObjectPropertyElement in_control_element, IOUserVideoObjectPropertyScope in_control_scope, IOUserVideoClassID in_control_class_id);Parameters
- in_driver:
The IOUserVideoDriver that owns this object.
- in_is_settable:
A Boolean value indicating if the control value can be set
- in_control_value:
A uint32_t for the control’s current slider value
- in_range:
The IOUserVideoSliderRange for control
- in_control_element:
The IOUserVideoObjectPropertyElement for the control
- in_control_scope:
The IOUserVideoObjectPropertyScope for the control
- in_control_class_id:
The IOUserVideoClassID of the control
Return Value
OSSharedPtr to an IOUserVideoSliderControl if it was successfully allocated and initialized
Discussion
If IOUserVideoSliderControl is subclassed to override behavior, don’t use this method to allocate or initialize the custom subclass.
