Suggestions for changes to the TRichEdit5 class

[MaxP]

Hi Antonio,

I suggest these changes to the TRichEdit5 class

1) bug on resize image in InsertBitmap

Code: Select all | Expand

METHOD InsertBitmap( hBitmap, nSizeX, nSizeY, lSpecial ) CLASS TRichEdit5

   local oClp
   DEFAULT lSpecial := .F.
   #ifndef _WIN64
/*****
      ::InsertPicture5( hBitmap ) */
      ::InsertPicture5( hBitmap, nSizeX, nSizeY )
   #else
      if !Empty( hBitMap )
         oClp := TClipBoard():New( CF_BITMAP, ::oWnd )
         oClp:SetBitmap( hBitmap )
         if lSpecial
            ::PasteSpecial()
         else
            ::Paste()
         endif
      endif
   #endif

Return nil

2) to improve typing speed after entering an image

2a) add a new method LostFocus

Code: Select all | Expand

CLASS TRichEdit5 FROM TControl

...
...

/*****/
   METHOD LostFocus( hWndGetFocus ) INLINE ::PostMsg( FM_CHANGE ), ::Super:LostFocus( hWndGetFocus )
ENDCLASS

2b) exclude the FM_CHANGE message in METHOD KeyChar

Code: Select all | Expand

METHOD KeyChar( nKey, nFlags ) CLASS TRichEdit5

   if ::lReadOnly .and. ! GetKeyState( VK_ESCAPE )
      return 0
   endif

   ::Super:KeyChar( nKey, nFlags )
/*****
   ::PostMsg( FM_CHANGE ) */

   if ::lHighlight
      ::PostMsg( FM_HIGHLIGHT )
   endif

return nil

2c) exclude the FM_CHANGE message in METHOD KeyDown

Code: Select all | Expand

METHOD KeyDown( nKey, nFlags ) CLASS TRichEdit5

   if ( nKey == VK_INSERT  .and. GetKeyState( VK_SHIFT ) .or. ;
        nKey == Asc( "V" ) .and. GetKeyState( VK_CONTROL ) )

      if ! ::lReadOnly
         ::Paste()
         ::PostMsg( FM_CHANGE )
      endif

      return 0
   endif

   if ::lReadOnly
      if nKey == VK_BACK .or. nKey == VK_DELETE .or. nKey == VK_RETURN
         return 0
      endif
   endif

   ::Super:KeyDown( nKey, nFlags )
/*****
   ::PostMsg( FM_CHANGE ) */

   if ::lHighlight
      if nKey == VK_DELETE .or. nKey == VK_BACK
         ::PostMsg( FM_HIGHLIGHT )
      endif
   endif

return nil
