+// 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)
