Likewise, we can only catch visible elements (i.e. connectors). * We only catch on the grid, if nothing else is close by (magnetic behaviour). * * The cursor which is used during creation of objects, while dragging polygon points * etc. (i.e. the mouse cursor) is always caught on all enabled catch alternatives (max 6). * * This is different, when moving selected objects. Instead of one mouse cursor, there are * four alternatives, which can be caught at the selected objects: * 1. the logically enclosing frame of every single object * 2. the logically enclosing frame of all selected objects * 3. highlighted points of all selected objects (polygon points, ...) * 4. the connectors of the selected objects * * As the first and second case exclude each other (the second is a refinement of the first one) * three alternatives remain, which are independent from each other. For 6 possible values for the * caught ones, we would end up with max. 18 different possible combinations! * * Therefore, we introduce the following simplifications: * 1. Connectors only catch on connectors * * Only max. 2*5+1 = 11 combinations remain for MoveDrag: * 1-3. enclosing frame on grid/border/helper lines * 4. enclosing frame on highlighted object points * 5. enclosing frame on enclosing frame * 6-8. highlighted points on grid/border/helper lines * 7. highlighted points on highlighted object points * 8-10. highlighted points on enclosing frame * 11. connectors on connectors * * We test for all of these possible 11 combinations in the MouseMove event in the DragMove * and those with the least need of correction are carried out. * * In the Resize() etc. methods we only catch the logically enclosing frame of the highlighted objects. */ /** Return value for SnapPos() method */ enum class SdrSnap { NOTSNAPPED = 0x00, XSNAPPED = 0x01, YSNAPPED = 0x02 }; namespace o3tl { template<> struct typed_flags : is_typed_flags {}; } // TODO SdrCrookMode::Stretch is not implemented yet!
