Where possible I // have credited the changes to those who contributed code corrections or // enhancements (names in brackets) or code suggestions (suggested by...) // // 1.0 - 1.13 20 Feb 1998 - 6 May 1999 // First release version. Progressed from being a basic // grid based on the original WorldCom Grid control // written by Joe Willcoxson (mailto:chinajoe@aol.com, // http://users.aol.com/chinajoe) to something a little // more feature rich. Rewritten so many times I doubt // there is a single line of Joe's code left. Many, many, // MANY people sent in bug reports and fixes. Thank you // all. // // 2.0 1 Feb 2000 // Rewritten to make the grid more object oriented, in // that the CGridCell class now takes care of cell-specific // tasks. This makes the code more robust, but more // importantly it allows the simple insertion of other // types of cells. // // 2.10 11 Mar 2000 - Ken Bertelson and Chris Maunder // - Additions for virtual CGridCell support of embedded tree // & cell buttons implementation // - Optional WYSIWYG printing // - Awareness of hidden (0 width/height) rows and columns for // key movements, cut, copy, paste, and autosizing // - CGridCell can make title tips display any text rather than // cell text only // - Minor vis bug fixes // - CGridCtrl now works with CGridCellBase instead of CGridCell // This is a taste of things to come. // // 2.20 30 Jul 2000 - Chris Maunder // - Font storage optimised (suggested by Martin Richter) // - AutoSizeColumn works on either column header, data or both // - EnsureVisible. The saga continues... (Ken) // - Rewrote exception handling // - Added TrackFocusCell and FrameFocusCell properties, as well as // ExpandLastColumn (suggested by Bruce E. Stemplewski). // - InsertColumn now allows you to insert columns at the end of the // column range (David Weibel) // - Shift-cell-selection more intuitive // - API change: Set/GetGridColor now Set/GetGridLineColor // - API change: Set/GetBkColor now Set/GetGridBkColor // - API change: Set/GetTextColor, Set/GetTextBkColor depricated // - API change: Set/GetFixedTextColor, Set/GetFixedBkColor depricated // - Stupid DDX_GridControl workaround removed. // - Added "virtual mode" via Set/GetVirtualMode // - Added SetCallbackFunc to allow callback functions in virtual mode // - Added Set/GetAutoSizeStyle // - AutoSize() bug fixed // - added GVIS_FIXEDROW, GVIS_FIXEDCOL states // - added Get/SetFixed[Row|Column]Selection // - cell "Get" methods now const'd. Sorry folks... // - GetMouseScrollLines now uses win98/W2K friendly code // - WS_EX_CLIENTEDGE style now implicit // // [ Only the latest version and major version changes will be shown ] //// // 2.25 13 Mar 2004 - Chris Maunder // - Minor changes so it will compile in VS.NET (inc. Whidbey) // - Fixed minor bug in EnsureVisible - Junlin Xu // - Changed AfxGetInstanceHandle for AfxGetResourceHandle in RegisterWindowClass // - Various changes thanks to Yogurt // // 2.26 13 Dec 2005 - Pierre Couderc // - Added sort in Virtual mode // - Change row/column order programatically or via drag and drop // - Added save/restore layer (for undoing row/column order changes) // // TODO: 1) Implement sparse grids (super easy now) // 2) Fix it so that as you drag select, the speed of selection increases // with time. // 3) Scrolling is still a little dodgy (too much grey area). I know there // is a simple fix but it's been a low priority // // ISSUES: 1) WindowFromPoint seems to do weird things in W2K. Causing problems for // the rigt-click-on-titletip code. // ///////////////////////////////////////////////////////////////////////////// #include "stdafx.h" #include "MemDC.h" #include "GridCtrl.h" #include <algorithm> // OLE stuff for clipboard operations #include <afxadv.h> // For CSharedFile #include <afxconv.h> // For LPTSTR -> LPSTR macros #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif // Spit out some messages as a sanity check for programmers #ifdef GRIDCONTROL_NO_TITLETIPS #pragma message(" -- CGridCtrl: No titletips for cells with large data") #endif #ifdef GRIDCONTROL_NO_DRAGDROP #pragma message(" -- CGridCtrl: No OLE drag and drop") #endif #ifdef GRIDCONTROL_NO_CLIPBOARD #pragma message(" -- CGridCtrl: No clipboard support") #endif #ifdef GRIDCONTROL_NO_PRINTING #pragma message(" -- CGridCtrl: No printing support") #endif IMPLEMENT_DYNCREATE(CGridCtrl, CWnd) // Get the number of lines to scroll with each mouse wheel notch // Why doesn't windows give us this function???
