Undo type selection

[cychia]

If I were to start an undo group with the following calls, which undo type should I should?

RVE.InsertPicture
RVE.SetItemExtraIntProperty(height)
RVE.SetItemExtraIntProperty(width)
RVE.InsertStringTag
RVE.SetCurrentItemExtraStrProperty(Alt);


Is rvutCustom type that I should be using?

Code: Select all

RVE.TopLevelEditor.BeginUndoGroup(rvutInsert);
RVE.TopLevelEditor.SetUndoGroupMode(True);
try
  if RVE.InsertPicture(...) then begin
    RVE.SetCurrentItemExtraIntProperty(rvepImageHeight, ...);
    RVE.SetCurrentItemExtraIntProperty(rvepImageWidth, ...);
    RVE.SetCurrentItemExtraStrProperty(rvespAlt, ...); 
  end;
finally
  RVE.TopLevelEditor.SetUndoGroupMode(False);
end;

I am not sure what you want with InsertStringTag. Do you want to insert image together with text string?

Actually, undo type (specified in BeginUndoGroup) is not used by TRichView itself. It can be read by UndoAction/RedoAction methods, and you can display its caption in undo/redo menu, like the demo Demos\Delphi\Editors\Editor 1\
