///////////////////////////////////////////////////////////////////////////// // 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 // RCS-ID: $Id$ // 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) // ///////////////////////////////////////////////////////////////////////////// #ifndef _WX_DIRDLGG_H_ #define _WX_DIRDLGG_H_ #ifdef __GNUG__ #pragma interface "dirdlgg.h" #endif #include "wx/defs.h" #if wxUSE_DIRDLG #include "wx/dialog.h" #include "wx/checkbox.h" #include "wx/treectrl.h" //----------------------------------------------------------------------------- // data //----------------------------------------------------------------------------- WXDLLEXPORT_DATA(extern const wxChar*) wxFileSelectorPromptStr; WXDLLEXPORT_DATA(extern const wxChar*) wxDirDialogDefaultFolderStr; //----------------------------------------------------------------------------- // classes //----------------------------------------------------------------------------- class wxDirItemData; class wxDirCtrl; class wxDirDialog; //----------------------------------------------------------------------------- // wxDirItemData //----------------------------------------------------------------------------- class WXDLLEXPORT wxDirItemData : public wxTreeItemData { public: wxDirItemData(wxString& path, wxString& name); ~wxDirItemData(); bool HasSubDirs(); void SetNewDirName( wxString path ); wxString m_path, m_name; bool m_isHidden; bool m_hasSubDirs; }; //----------------------------------------------------------------------------- // wxDirCtrl //----------------------------------------------------------------------------- class WXDLLEXPORT wxDirCtrl: public wxTreeCtrl { public: bool m_showHidden; wxTreeItemId m_rootId; wxDirCtrl(); wxDirCtrl(wxWindow *parent, const wxWindowID id = -1, const wxString &dir = wxDirDialogDefaultFolderStr, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, const long style = wxTR_HAS_BUTTONS, const wxString& name = wxTreeCtrlNameStr ); void ShowHidden( const bool yesno ); void OnExpandItem(wxTreeEvent &event ); void OnCollapseItem(wxTreeEvent &event ); void OnBeginEditItem(wxTreeEvent &event ); void OnEndEditItem(wxTreeEvent &event ); protected: void CreateItems(const wxTreeItemId &parent); void SetupSections(); wxArrayString m_paths, m_names; private: DECLARE_EVENT_TABLE() DECLARE_DYNAMIC_CLASS(wxDirCtrl) }; //----------------------------------------------------------------------------- // wxDirDialog //----------------------------------------------------------------------------- class WXDLLEXPORT wxDirDialog: public wxDialog { public: wxDirDialog(wxWindow *parent, const wxString& message = wxFileSelectorPromptStr, const wxString& defaultPath = wxEmptyString, long style = 0, const wxPoint& pos = wxDefaultPosition); inline void SetMessage(const wxString& message) { m_message = message; } inline void SetPath(const wxString& path) { m_path = path; } inline void SetStyle(long style) { m_dialogStyle = style; } inline wxString GetMessage() const { return m_message; } inline wxString GetPath() const { return m_path; } inline long GetStyle() const { return m_dialogStyle; } int ShowModal(); void OnTreeSelected( wxTreeEvent &event ); void OnTreeKeyDown( wxTreeEvent &event ); void OnOK(wxCommandEvent& event); void OnCancel(wxCommandEvent& event); void OnNew(wxCommandEvent& event); // void OnCheck(wxCommandEvent& event); protected: // implementation wxString m_message; long m_dialogStyle; wxString m_path; wxDirCtrl *m_dir; wxTextCtrl *m_input; wxCheckBox *m_check; // not yet used wxButton *m_ok, *m_cancel, *m_new; private: DECLARE_EVENT_TABLE() DECLARE_DYNAMIC_CLASS(wxDirDialog) }; #endif #endif // _WX_DIRDLGG_H_
