-// Notes: wxDirDialog class written by Harm van der Heijden,
-// uses wxDirCtrl class written by Robert Roebling for the
-// wxFile application, modified by Harm van der Heijden
-//
-// Description: This generic dirdialog implementation defines three classes:
-// 1) wxDirItemData(public wxTreeItemData) stores pathname and
-// displayed name for each item in the directory tree
-// 2) wxDirCtrl(public wxTreeCtrl) is a tree widget that
-// displays a directory tree. It is possible to define sections
-// for fast access to parts of the file system (such as the
-// user's homedir, /usr/local, /tmp ...etc), similar to
-// Win95 Explorer's shortcuts to 'My Computer', 'Desktop', etc.
-// 3) wxDirDialog is the dialog box itself. The user can choose
-// a directory by navigating the tree, or by typing a dir
-// in an inputbox. The inputbox displays paths selected in the
-// tree. It is possible to create new directories. The user
-// will automatically be prompted for dir creation if he
-// enters a non-existing dir.
-//
-// TODO/BUGS: - standard sections only have reasonable defaults for Unix
-// (but others are easily added in wxDirCtrl::SetupSections)
-// - No direct support for "show hidden" toggle. Partly due
-// to laziness on my part and partly because
-// wxFindFirst/NextFile never seems to find hidden dirs
-// anyway.
-// - No automatic update of the tree (branch) after directory
-// creation.
-// - I call wxBeginBusyCursor while expanding items (creating
-// a new branch might take a few seconds, especially if a
-// CDROM drive or something is involved) but that doesn't
-// seem to do anything. Need to look into that.
-// - Am still looking for an efficient way to delete wxTreeCtrl
-// branches. DeleteChildren has disappeared and
-// CollapseAndReset( parent ) deletes the parent as well.
-// - The dialog window layout is done using wxConstraints. It
-// works, but it's not as simple as I'd like it to be (see
-// comments in wxDirDialog::doSize)
