114 | * Most user interface commands are routed through this, to give us the | |
115 | * Undo/Redo mechanism. If you add more commands, such as changing the shape colour, | |
116 | * you will need to add members to 'remember' what the user applied (for 'Do') and what the | |
117 | * previous state was (for 'Undo'). | |
118 | * You can have one member for each property to be changed. Assume we also have | |
119 | * a pointer member wxShape *shape, which is set to the shape being changed. | |
120 | * Let's assume we're changing the shape colour. Our member for this is shapeColour. | |
121 | * | |
122 | * - In 'Do': | |
123 | * o Set a temporary variable 'temp' to the current colour for 'shape'. | |
124 | * o Change the colour to the new colour. | |
125 | * o Set shapeColour to the _old_ colour, 'temp'. | |
126 | * - In 'Undo': | |
127 | * o Set a temporary variable 'temp' to the current colour for 'shape'. | |
128 | * o Change the colour to shapeColour (the old colour). | |
129 | * o Set shapeColour to 'temp'. | |
130 | * | |
131 | * So, as long as we have a pointer to the shape being changed, | |
132 | * we only need one member variable for each property. | |
133 | * | |
134 | * PROBLEM: when an Add shape command is redone, the 'shape' pointer changes. | |
135 | * Assume, as here, that we keep a pointer to the old shape so we reuse it | |
136 | * when we recreate. | |
