Detailed Description
Item identifier used to identify items supplied through skin interfaces.
Item ID consists of two integers: major and minor parts of the ID.
Note that only LinearOrder() member function requires linking against the library, all the other methods are inlined.
Public Member Functions void Set (const TInt aMajor, const TInt aMinor) Sets specified major and minor parts. void Set (const TUid aMajor, const TInt aMinor) Sets specified major and minor parts where major part is given as a UID. void Set (const TAknsItemID &aID) Sets major and minor parts according to the given item ID. Static Public Member Functions static IMPORT_C TInt LinearOrder (const TAknsItemID &aFirst, const TAknsItemID &aSecond) Determines the order of two TAknsItemID objects. Data Fields TInt iMajor Major part of the item ID as an integer. TInt iMinor Minor part of the item ID as an integer.
Member Function Documentation
static IMPORT_C TInt TAknsItemID::LinearOrder ( const TAknsItemID & aFirst , const TAknsItemID & aSecond ) [static]
Determines the order of two TAknsItemID objects.
Implements an algorithm that determines the order of two item ID objects.
Parameters:
aFirst Constant reference to the first object to be compared. aSecond Constant reference to the second object to be compared.
Returns: 0 if the two objects are equal, negative value if the first object is less than the second and positive value if the first object is greater than the second. Implementation details: To improve binary search, current implementation first compares minor part and after that the major part of the item ID. Since most lists have several objects with equal major parts this makes the algorithm more efficient.
void TAknsItemID::Set ( const TAknsItemID & aID ) [inline]
Sets major and minor parts according to the given item ID.
Parameters:
aID Item ID to be used to get the values.
void TAknsItemID::Set ( const TUid aMajor , const TInt aMinor ) [inline]
Sets specified major and minor parts where major part is given as a UID.
Parameters:
aMajor Major part of the item ID as a UID. aMinor Minor part of the item ID.
void TAknsItemID::Set ( const TInt aMajor , const TInt aMinor ) [inline]
Sets specified major and minor parts.
Parameters:
aMajor Major part of the item ID. aMinor Minor part of the item ID.
Field Documentation
Major part of the item ID as an integer.
Minor part of the item ID as an integer.
