\section{\class{wxGenericDirCtrl}}\label{wxgenericdirctrl}

This control can  be used to place a directory listing (with optional files) on an arbitrary window.

The control contains a \helpref{wxTreeCtrl}{wxtreectrl} window representing the directory
hierarchy, and optionally, a \helpref{wxChoice}{wxchoice} window containing a list of filters.

\membersection{wxGenericDirCtrl::\destruct{wxGenericDirCtrl}}\label{wxgenericdirctrldtor}

\func{}{\destruct{wxGenericDirCtrl}}{\void}

Destructor.

\membersection{wxGenericDirCtrl::Create}\label{wxgenericdirctrlcreate}

\func{bool}{Create}{\param{wxWindow* }{parent}, \param{const wxWindowID }{id = -1}, \param{const wxString\& }{dir = wxDirDialogDefaultFolderStr}, \param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize}, \param{long }{style = wxDIRCTRL\_3D\_INTERNAL|wxSUNKEN\_BORDER}, \param{const wxString\& }{filter = wxEmptyString}, \param{int }{defaultFilter = 0}, \param{const wxString\& }{name = wxTreeCtrlNameStr}}

Create function for two-step construction. See \helpref{wxGenericDirCtrl::wxGenericDirCtrl}{wxgenericdirctrlwxgenericdirctrl} for details.

\membersection{wxGenericDirCtrl::Init}\label{wxgenericdirctrlinit}

\func{void}{Init}{\void}

Initializes variables.

\membersection{wxGenericDirCtrl::CollapseTree}\label{wxgenericdirctrlcollapsetree}

\func{void}{CollapseTree}{\void}

Collapses the entire tree.

\membersection{wxGenericDirCtrl::ExpandPath}\label{wxgenericdirctrlexpandpath}

\func{bool}{ExpandPath}{\param{const wxString\& }{path}}

Tries to expand as much of the given path as possible, so that the filename or directory is visible in the tree control.

\membersection{wxGenericDirCtrl::GetDefaultPath}\label{wxgenericdirctrlgetdefaultpath}

\constfunc{wxString}{GetDefaultPath}{\void}

Gets the default path.

Gets the currently-selected directory or filename.

\membersection{wxGenericDirCtrl::GetFilePath}\label{wxgenericdirctrlgetfilepath}

\constfunc{wxString}{GetFilePath}{\void}

Gets selected filename path only (else empty string).

This function doesn't count a directory as a selection.

\membersection{wxGenericDirCtrl::GetTreeCtrl}\label{wxgenericdirctrlgettreectrl}

\constfunc{wxTreeCtrl*}{GetTreeCtrl}{\void}

Returns a pointer to the tree control.

\membersection{wxGenericDirCtrl::ReCreateTree}\label{wxgenericdirctrlrecreatetree}

\func{void}{ReCreateTree}{\void}

Collapse and expand the tree, thus re-creating it from scratch.
May be used to update the displayed directory content.
