52 class IMergeEditStatus;
58 This class is the base class for WinMerge editor panels.
59 It hooks the painting of ghost lines (GetLineColors), the shared
60 scrollbar (OnUpdateSibling...).
61 It offers the UI interface commands to work with diffs
64 If we keep GetLineColors here, we should clear DIFF flag here
65 and not in CGhostTextBuffer (when insertText/deleteText).
66 Small problem... This class doesn't derives from CGhostTextBuffer...
67 We could define a new class which derives from CGhostTextBuffer to clear the DIFF flag.
68 and calls a virtual function for additional things to do on the flag.
69 Maybe in the future...
