* \brief A Widget to browse through the Hurricane objetcs.

|
|
* \section secInspectorMM Inspector Memory Management
|
|
*
|
|
* In order to keep the memory footprint of the Inspector as
|
|
* small as possible only the currently viewed Record is allocated.
|
|
* The only exception is the root Record itself, which we must
|
|
* kept for it has not been passed as a Slot but as a Record.
|
|
* Be aware however, that the root Record is destroyed the
|
|
* moment the Inspector is, so do not uses the root Record in
|
|
* context from which the Inspector has been spawned.
|
|
*
|
|
* The history from the root Record to the deepest reached
|
|
* level of the data structure is kept in a vector of Slots.
|
|
* We choose Slot over Record because they are lightweight object.
|
|
* Slots containts only a name (usually the object's attribute
|
|
* name) and a pointer to that attribute. The Record associated
|
|
* to the attribute is generated on demand. To have a completly
|
|
* uniform history we must create a special Slot from the root
|
|
* Record, unlike others this Slot contains directly the Record
|
|
* and not the attribute pointer it has been generated from.
|
|
*
|
|
* When an Inspector windows is closed by the window manager,
|
|
* the widget is not simply hidden, it is fully destroyed
|
|
* (see the QWidget \c Qt::WA_DeleteOnClose attribute). Thus, pointers
|
|
* to an Inspector Widget are not to be kept.
|
|
*
|
|
* Any number of Inspector could be created simultanously, even
|
|
* on the same datas. Slot & Record beeing on demand, expandables,
|
|
* objects.
