// Name: dirdlgg.h
|
||||
// Purpose: wxDirDialog
|
||||
// Author: Harm van der Heijden and Robert Roebling
|
||||
// Modified by:
|
||||
// Created: 12/12/98
|
||||
// Copyright: (c) Harm van der Heijden and Robert Roebling
|
||||
// Licence: wxWindows licence
|
||||
//
|
||||
// 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)

||||
