typedef int(*) getPropertyFunc(sciPointObj *)

Prototype of functions used to get a specific property of an handle. The sciPointObj is the object to get the property from The return value is 0 if the call was successful and -1 otherwise.

Definition at line 33 of file setGetHashTable.h.

typedef struct hashtable GetPropertyHashTable

Hide the real type of hashtable

Definition at line 19 of file setGetHashTable.h.

typedef int(*) setPropertyFunc(sciPointObj *, int, int, int, int)

Prototype of functions used to set a specific property of an handle. The sciPointObj is the object to get the property from The return value is SET_PROERTY_SUCEED if the call was successful and a redraw is needed SET_PROPERTY_UNCHANGED if nothing was actually changed and SET_PROPERTY_ERROR if an error occurred.
