- Do/Undo 30/7/98
-
- 1) We have a csCommandState, and in csDiagramCommand you have a list of
- these. This allows undo to work with several shapes at once.
-
- 2) Instead of storing info about each operation, e.g. separate pens, colours,
- etc., we simply use a copy of the shape.
- In csCommandState, we have a pointer to the actual shape in the canvas, m_currentShape.
- We also have wxShape* m_shapeState which stores the requested or previous state
- (depending on whether it's before the Do or after the Do.
-
- - In Do: save a temp copy of the old m_currentShape (i.e. the state just before it's changed).
- Change the data pointed to by m_currentShape to the new attributes stored in m_shapeState.
- Now assign the temp copy to m_shapeState, for use in Undo.
-
- wxShape* temp = m_currentShape->Copy(); // Take a copy of the current state
- m_currentShape->Set(m_shapeState); // Apply the new state (e.g. moving, changing colour etc.)
- delete m_shapeState; // Delete the previous 'old state'.
- m_shapeState = temp; // Remember the new 'old state'.
