\section{\class{wxDataViewItem}}\label{wxdataviewitem}
|
|
|
|
wxDataViewItem is a small opaque class that represents an
|
|
item in a \helpref{wxDataViewCtrl}{wxdataviewctrl} in a
|
|
persistent way, i.e. indepent of the position of the
|
|
item in the control or changes to its contents. It must
|
|
hold a unique ID of type {\it void*} in its only field
|
|
and can be converted to a from it.
|
|
|
|
If the ID is {\it NULL} the wxDataViewItem is invalid and
|
|
\helpref{IsOk}{wxdataviewitemisok} will return {\it false}
|
|
which used in many places in the API of wxDataViewCtrl
|
|
to indicate that e.g. no item was found. An ID of NULL
|
|
is also used to indicate the invisible root. Examples
|
|
for this are
|
|
\helpref{wxDataViewModel::GetParent}{wxdataviewmodelgetparent} and
|
|
\helpref{wxDataViewModel::GetChildren}{wxdataviewmodelgetchildren}.
