//////////////////////////////////////////////////////////////////////////// // Name: stc.cpp // Purpose: A wxWindows implementation of Scintilla. This class is the // one meant to be used directly by wx applications. It does not // derive directly from the Scintilla classes, but instead // delegates most things to the real Scintilla class. // This allows the use of Scintilla without polluting the // namespace with all the classes and identifiers from Scintilla. // // Author: Robin Dunn // // Created: 13-Jan-2000 // RCS-ID: $Id$ // Copyright: (c) 2000 by Total Control Software // Licence: wxWindows license ///////////////////////////////////////////////////////////////////////////// #include #include "wx/stc/stc.h" #include "ScintillaWX.h" #include #include #include #include #include //---------------------------------------------------------------------- const wxChar* wxSTCNameStr = wxT("stcwindow"); #ifdef MAKELONG #undef MAKELONG #endif #define MAKELONG(a, b) ((a) | ((b) << 16)) static long wxColourAsLong(const wxColour& co) { return (((long)co.Blue() << 16) | ((long)co.Green() << 8) | ((long)co.Red())); } static wxColour wxColourFromLong(long c) { wxColour clr; clr.Set(c & 0xff, (c >> 8) & 0xff, (c >> 16) & 0xff); return clr; } static wxColour wxColourFromSpec(const wxString& spec) { // spec should be "#RRGGBB" long red, green, blue; red = green = blue = 0; spec.Mid(1,2).ToLong(&red, 16); spec.Mid(3,2).ToLong(&green, 16); spec.Mid(5,2).ToLong(&blue, 16); return wxColour(red, green, blue); } //---------------------------------------------------------------------- DEFINE_EVENT_TYPE( wxEVT_STC_CHANGE ) DEFINE_EVENT_TYPE( wxEVT_STC_STYLENEEDED ) DEFINE_EVENT_TYPE( wxEVT_STC_CHARADDED ) DEFINE_EVENT_TYPE( wxEVT_STC_SAVEPOINTREACHED ) DEFINE_EVENT_TYPE( wxEVT_STC_SAVEPOINTLEFT ) DEFINE_EVENT_TYPE( wxEVT_STC_ROMODIFYATTEMPT ) DEFINE_EVENT_TYPE( wxEVT_STC_KEY ) DEFINE_EVENT_TYPE( wxEVT_STC_DOUBLECLICK ) DEFINE_EVENT_TYPE( wxEVT_STC_UPDATEUI ) DEFINE_EVENT_TYPE( wxEVT_STC_MODIFIED ) DEFINE_EVENT_TYPE( wxEVT_STC_MACRORECORD ) DEFINE_EVENT_TYPE( wxEVT_STC_MARGINCLICK ) DEFINE_EVENT_TYPE( wxEVT_STC_NEEDSHOWN ) DEFINE_EVENT_TYPE( wxEVT_STC_POSCHANGED ) DEFINE_EVENT_TYPE( wxEVT_STC_PAINTED ) DEFINE_EVENT_TYPE( wxEVT_STC_USERLISTSELECTION ) DEFINE_EVENT_TYPE( wxEVT_STC_URIDROPPED ) DEFINE_EVENT_TYPE( wxEVT_STC_DWELLSTART ) DEFINE_EVENT_TYPE( wxEVT_STC_DWELLEND ) DEFINE_EVENT_TYPE( wxEVT_STC_START_DRAG ) DEFINE_EVENT_TYPE( wxEVT_STC_DRAG_OVER ) DEFINE_EVENT_TYPE( wxEVT_STC_DO_DROP ) DEFINE_EVENT_TYPE( wxEVT_STC_ZOOM ) DEFINE_EVENT_TYPE( wxEVT_STC_HOTSPOT_CLICK ) DEFINE_EVENT_TYPE( wxEVT_STC_HOTSPOT_DCLICK ) DEFINE_EVENT_TYPE( wxEVT_STC_CALLTIP_CLICK ) BEGIN_EVENT_TABLE(wxStyledTextCtrl, wxControl) EVT_PAINT (wxStyledTextCtrl::OnPaint) EVT_SCROLLWIN (wxStyledTextCtrl::OnScrollWin) EVT_SCROLL (wxStyledTextCtrl::OnScroll) EVT_SIZE (wxStyledTextCtrl::OnSize) EVT_LEFT_DOWN (wxStyledTextCtrl::OnMouseLeftDown) // Let Scintilla see the double click as a second click EVT_LEFT_DCLICK (wxStyledTextCtrl::OnMouseLeftDown) EVT_MOTION (wxStyledTextCtrl::OnMouseMove) EVT_LEFT_UP (wxStyledTextCtrl::OnMouseLeftUp) #if defined(__WXGTK__) || defined(__WXMAC__) EVT_RIGHT_UP (wxStyledTextCtrl::OnMouseRightUp) #else EVT_CONTEXT_MENU (wxStyledTextCtrl::OnContextMenu) #endif EVT_MOUSEWHEEL (wxStyledTextCtrl::OnMouseWheel) EVT_MIDDLE_UP (wxStyledTextCtrl::OnMouseMiddleUp) EVT_CHAR (wxStyledTextCtrl::OnChar) EVT_KEY_DOWN (wxStyledTextCtrl::OnKeyDown) EVT_KILL_FOCUS (wxStyledTextCtrl::OnLoseFocus) EVT_SET_FOCUS (wxStyledTextCtrl::OnGainFocus) EVT_SYS_COLOUR_CHANGED (wxStyledTextCtrl::OnSysColourChanged) EVT_ERASE_BACKGROUND (wxStyledTextCtrl::OnEraseBackground) EVT_MENU_RANGE (10, 16, wxStyledTextCtrl::OnMenu) EVT_LISTBOX_DCLICK (-1, wxStyledTextCtrl::OnListBox) END_EVENT_TABLE() IMPLEMENT_CLASS(wxStyledTextCtrl, wxControl) IMPLEMENT_DYNAMIC_CLASS(wxStyledTextEvent, wxCommandEvent) #ifdef LINK_LEXERS // forces the linking of the lexer modules int Scintilla_LinkLexers(); #endif //---------------------------------------------------------------------- // Constructor and Destructor wxStyledTextCtrl::wxStyledTextCtrl(wxWindow *parent, wxWindowID id, const wxPoint& pos, const wxSize& size, long style, const wxString& name) : wxControl(parent, id, pos, size, style | wxVSCROLL | wxHSCROLL | wxWANTS_CHARS | wxCLIP_CHILDREN, wxDefaultValidator, name) { #ifdef LINK_LEXERS Scintilla_LinkLexers(); #endif m_swx = new ScintillaWX(this); m_stopWatch.Start(); m_lastKeyDownConsumed = FALSE; m_vScrollBar = NULL; m_hScrollBar = NULL; #if wxUSE_UNICODE // Put Scintilla into unicode (UTF-8) mode SetCodePage(wxSTC_CP_UTF8); #endif } wxStyledTextCtrl::~wxStyledTextCtrl() { delete m_swx; } //---------------------------------------------------------------------- long wxStyledTextCtrl::SendMsg(int msg, long wp, long lp) { return m_swx->WndProc(msg, wp, lp); } //---------------------------------------------------------------------- // BEGIN generated section.
