Field Documentation

char* _CControl::names

A buffer that contains the names of the CControlChoice items.

The name fields of the items point to strings within this buffer, so there is no need to work with this member directly except freeing the buffer if the control is disposed of.

struct { ... } _CControl::choices

List of the possible choices that this control allows.

The members of this struct are only valid if the type is CC_TYPE_CHOICE.
