Detailed Description

The HFloatTablesAsHList class is fake a HFloatTables to act as a HList. With this class you can browse and see an unexisting (sql point of view) table.
You can put a HFloatTables instance to the HFloatTablesAsHList, and after it you can use the class as a HList.

Warning

(1) The keys are generated (key in HList). This generated keys are independent from the keys in sql. The reason of the generated keys is that it can be same records which does not appear in the database so they can't have any key value. This records are tipically the NEW and UNDEF and CANCELLED records.
So keep in mind that the keys are generated! This mean for example: you can't find the value of the active_key in the HFloatTables!

(2) If there is any changes on the data tables (in HFloatTables) the changes are only actualized, when the refreshValuesKeys() function is called! The reason is the speeding up the system. If you modify anything on the HFloatTable it would trigger a new data copy cycle. Because this modification signals are triggered every time when the gui cells is modified, it would be trigger many unnecessary refresh cycle.
So the values from the HFloatTables only copied to HFloatTablesAsHList when you call this refreshValuesKeys() function.
That means for exmample: if the user edit a record of the HFloatTable it is recommend to call refreshValuesKeys() only when the user hit Ok to the edit dialog.

If you have a HSmallText typed field in the tempate list which sql name is "NON_SQL_LIST_SERIAL" that case the refreshValuesKeys() will fill that field values with an index number.

Constructor & Destructor Documentation

HFloatTablesAsHList::HFloatTablesAsHList	(	HFloatTables *	memt,
		HList *	templ = NULL,
		bool	clone_struct_from_memt = false
	)

Constructor. Creates a HFloatTablesAsHList which fakes a HFloatTable get in memt parameter as HList

Parameters

memt	the HFloatTables class to fake as Hlist
templ	if we dont want to specify the data fields of the HList (which faked) we can put this templ parameter and the constructor clones the data fields from this parameter
clone_struct_from_memt	if this true (false by default!) and the templ is NULL the HList (which faked) will be clones the data fields from the baserecord of the HFloatTables. So if you would like to the HList view same as the base record of FloatTables you should call HFloatTablesAsHList(some_pointer,NULL,true); This means that by default the HFloatTablesAsHList will be created with undefined data fields! (Have to fill with HTableBase functions)

(

void

)

Returns the active table/record.

int HFloatTablesAsHList::readList ( QString  filter = "", bool  all = true  )

virtualslot

Inherited function(HList): calls the HFloatTables::readDBTable() with the filter and calls refreshValuesKeys() after it.

Parameters

filter	this parameter is passed to HFloatTables::readDBTable()
all	does't do anything.
