 194 Instead of the following giant switch statement, you could something like the following:
 195 ActionInterface * ActionHandler::setCurrentAction(ActionInterface * action)
 196 {
 197         GraphicView * gv = mainWindow->getGraphicView();
 198         Document * doc = mainWindow->getDocument();

 201         if (gv == NULL || doc == NULL)

 203                 return NULL;
 204         }
 205
 206         if (action)
 207                 gv->setCurrentAction(action);
 208
 209         return action;
 210 }
 211 Then you'd call it with:
 212                 a = new ActionEditUndo(true, *doc, *gv);
 213
 214 Hmmm.... We need gv & doc *before* we call this...
 215
 216 What you'd do then is have the form of the thing worked ahead of time and the function
 217 itself would create the gv & doc. So for the EditUndo, we'd have:
 218         FunctionCreateAction(bool);
 219         FunctionCreateAction(void);
 220
 221 Well... The problem is the action, they're all different...
