102 We need at least *three* handles for this object:
107 We need to think about the intuitive way (if there is any) to grab and
108 manipulate a complex object like this... Need to think, "What should happen when
109 I click here and drag there?"
111 Also: should put the snap logic into the Object base class (as a static method)...
115 // Need to add checking here for clicking on a member of a group (Container),
116 // and checking for if it's a top level container (the DrawingView's document).
118 One approach is to check for the parent of the container: If it's NULL, then it's
119 the DrawingView's document. It might be better, though, to set a boolean like
120 isTopLevelContainer so that we can do things like edit members of a group without
121 having to ungroup them first (like Inkscape).

165 // DrawingView's document. If so, we ignore the state of the container.
166 // Otherwise, we care about the state of the container. :-)

173 if (state == OSSelected)
185 What we need to do is check for whether or not we're a top level container,
186 and override the passing of stuff into the objects held. So here, if we're *NOT*
187 a top level container, instead of passing PointerMoved to our contained objects,
188 we check to see if our bounds are met (for selection rectangle, e.g.).
190 Also, for things like being able to split point's hot spots we need to be able
191 to check for that crap in the top level container. Which means that objects can
192 still know how to move themselves, but they can also defer to their container
193 as well. Which also means that things like HitTest() need to be in the Object
194 class so that we can leverage that stuff here as well.
197 // The TLC is passing all mouse movement here, so we're doing the same here.
198 // Need to adjust all other objects to handle things correctly.
200 // One optimization that will need to be done eventually is to subdivide the screen
201 // into parts and keep subdividing until an acceptable number of objects lie within
202 // the slice. This way, the GUI will still be responsive and *not* have to test
203 // every object for collision.

535 This is a real problem. While having a pointer in the Dimension to this line's points
536 is fast & easy, it creates a huge problem when trying to replicate an object like this.
538 Maybe a way to fix that then, is to have reference numbers instead of pointers. That
539 way, if you copy them, ... you might still have problems. Because you can't be sure if
540 a copy will be persistant or not, you then *definitely* do not want them to have the
541 same reference number.
