  11 // Notes:       wxDirDialog class written by Harm van der Heijden,
  12 //              uses wxDirCtrl class written by Robert Roebling for the
  13 //              wxFile application, modified by Harm van der Heijden
  14 //
  15 // Description: This generic dirdialog implementation defines three classes:
  16 //              1) wxDirItemData(public wxTreeItemData) stores pathname and
  17 //              displayed name for each item in the directory tree
  18 //              2) wxDirCtrl(public wxTreeCtrl) is a tree widget that
  19 //              displays a directory tree. It is possible to define sections
  20 //              for fast access to parts of the file system (such as the
  21 //              user's homedir, /usr/local, /tmp ...etc), similar to
  22 //              Win95 Explorer's shortcuts to 'My Computer', 'Desktop', etc.
  23 //              3) wxDirDialog is the dialog box itself. The user can choose
  24 //              a directory by navigating the tree, or by typing a dir
  25 //              in an inputbox. The inputbox displays paths selected in the
  26 //              tree. It is possible to create new directories. The user
  27 //              will automatically be prompted for dir creation if he
  28 //              enters a non-existing dir.
  29 //
  30 // TODO/BUGS:   - standard sections only have reasonable defaults for Unix
  31 //                (but others are easily added in wxDirCtrl::SetupSections)
  32 //              - No direct support for "show hidden" toggle. Partly due
  33 //                to laziness on my part and partly because
  34 //                wxFindFirst/NextFile never seems to find hidden dirs
  35 //                anyway.
  36 //              - No automatic update of the tree (branch) after directory
  37 //                creation.
  38 //              - I call wxBeginBusyCursor while expanding items (creating
  39 //                a new branch might take a few seconds, especially if a
  40 //                CDROM drive or something is involved) but that doesn't
  41 //                seem to do anything. Need to look into that.
  42 //              - Am still looking for an efficient way to delete wxTreeCtrl
  43 //                branches. DeleteChildren has disappeared and
  44 //                CollapseAndReset( parent ) deletes the parent as well.
  45 //              - The dialog window layout is done using wxConstraints. It
  46 //                works, but it's not as simple as I'd like it to be (see
  47 //                comments in wxDirDialog::doSize)
