to hide vertical level connectors.}

implemented in the system library {\tt comctl32.dll}. Some versions of this
library are known to have bugs with handling the tree control colours: the
usual symptom is that the expanded items leave black (or otherwise incorrectly
-coloured) background behind them, especially for the controls using non
-default background colour. The recommended solution is to upgrade the {\tt comctl32.dll}

+\constfunc{unsigned int}{GetChildrenCount}{\param{const wxTreeItemId\&}{ item}, \param{bool}{ recursively = {\tt true}}}
Returns the number of items in the branch. If {\it recursively} is {\tt true}, returns the total number
of descendants, otherwise only one level of children is counted.
\membersection{wxTreeCtrl::GetCount}\label{wxtreectrlgetcount}
-\constfunc{int}{GetCount}{\void}

Returns the number of items in the control.
Returns the item's parent.

-\constfunc{size\_t}{GetSelections}{\param{wxArrayTreeItemIds\& }{selection}}

Fills the array of tree items passed in with the currently selected items. This
function can be called only if the control has the wxTR\_MULTIPLE style.

-\func{bool}{SelectItem}{\param{const wxTreeItemId\&}{ item}, \param{bool }{select = \true}}

Selects the given item. In multiple selection controls, can be also used to
deselect a currently selected item if the value of \arg{select} is false.
\func{void}{UnselectItem}{\param{const wxTreeItemId\& }{item}}
Unselects the given item. This works in multiselection controls only.
