item's image is also taken into account.
The return value is {\tt true} if the rectangle was successfully retrieved or {\tt false}
-if it was not (in this case {\it rect} is not changed) - for example, if the
+if it was not (in this case {\it rect} is not changed) -- for example, if the
item is currently invisible.
+Notice that the rectangle coordinates are logical, not physical ones. So, for
+example, the x coordinate may be negative if the tree has a horizontal
+scrollbar and its position is not $0$.

\pythonnote{The wxPython version of this method requires only the
{\tt item} and {\tt textOnly} parameters. The return value is either a
{\tt wxRect} object or {\tt None}.}
\membersection{wxTreeCtrl::GetChildrenCount}\label{wxtreectrlgetchildrencount}
-\constfunc{size\_t}{GetChildrenCount}{\param{const wxTreeItemId\&}{ item}, \param{bool}{ recursively = {\tt true}}}
+\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{size\_t}{GetCount}{\void}
+\constfunc{unsigned int}{GetCount}{\void}
Returns the number of items in the control.
Returns the item's parent.

-\constfunc{wxTreeItemId}{GetParent}{\param{const wxTreeItemId\&}{ item}}

-{\bf NOTE:} This function is deprecated and will only work if {\tt WXWIN\_COMPATIBILITY\_2\_2}

-
-Returns the item's parent.

\membersection{wxTreeCtrl::GetPrevSibling}\label{wxtreectrlgetprevsibling}
\constfunc{wxTreeItemId}{GetPrevSibling}{\param{const wxTreeItemId\&}{ item}}
Returns the previous visible item.
+\membersection{wxTreeCtrl::GetQuickBestSize}\label{wxtreectrlgetquickbestsize}
+
+\constfunc{bool}{GetQuickBestSize}{\void}
+
+Returns true if the control will use a quick calculation for the best size,
+looking only at the first and last items. The default is false.

-\constfunc{size\_t}{GetSelections}{\param{wxArrayTreeItemIds\& }{selection}}
+\constfunc{unsigned int}{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.
\membersection{wxTreeCtrl::HitTest}\label{wxtreectrlhittest}
-\func{wxTreeItemId}{HitTest}{\param{const wxPoint\& }{point}, \param{int\& }{flags}}
+\constfunc{wxTreeItemId}{HitTest}{\param{const wxPoint\& }{point}, \param{int\& }{flags}}
Calculates which (if any) item is under the given point, returning the tree item
id at this point plus extra information {\it flags}. {\it flags} is a bitlist of the following:
positive value if the first item is less than, equal to or greater than the
second one.
-The base class version compares items alphabetically.
+Please note that you \textbf{must} use wxRTTI macros
+\helpref{DECLARE\_DYNAMIC\_CLASS}{declaredynamicclass} and
+\helpref{IMPLEMENT\_DYNAMIC\_CLASS}{implementdynamicclass} if you override this
+function because otherwise the base class considers that it is not overridden
+and uses the default comparison, i.e. sorts the items alphabetically, which
+allows it optimize away the calls to the virtual function completely.

-\func{bool}{SelectItem}{\param{const wxTreeItemId\&}{ item}, \param{bool }{select = \true}}
+\func{void}{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.
Sets the colour of the item's text.
+\membersection{wxTreeCtrl::SetQuickBestSize}\label{wxtreectrlsetquickbestsize}
+
+\func{void}{SetQuickBestSize}{\param{bool}{ quickBestSize}}
+
+If true is passed, specifies that the control will use a quick calculation for the best size,
+looking only at the first and last items. Otherwise, it will look at all items.
+The default is false.

\func{void}{SetStateImageList}{\param{wxImageList*}{ imageList}}
\func{void}{UnselectItem}{\param{const wxTreeItemId\& }{item}}
Unselects the given item. This works in multiselection controls only.
