- @package core.events
- @brief General events
- Put here only truly general events. Once you find that your event can be
- generated in more than one class, put your event here. Otherwise,
- leave it in your class file. Events are expected to be grass/gis related.
- General notice:
- Command events are propagated to parent windows. However, they do not propagate
- beyond dialogs. Events do not propagate at all.
- Command events works only with windows, not EvtHandlers, so for other objects
- than windows you need to have extra parameter - guiparent - which can be used
- for creating command events.
- \code
- mapEvent = gMapCreated(self._guiparent.GetId(), ...)
- wx.PostEvent(self._guiparent, mapEvent)
- \endcode
- @todo naming conventions for events
