MAknsControlContext Class Reference
| class MAknsControlContext |
Interface that provides context specific skin parameters. This interface is used by AknsDrawUtils to query context specific parameters, such as background override. Application should instantiate a class that implements this interface and provide pointer to it using MObjectProvider::MopSupplyObject in the appropriate control.
This is a public class with exported functions. The class is not intended for user derivation - concrete classes implementing the interface are provided by the library. See CAknsBasicBackgroundControlContext and CAknsListBoxBackgroundControlContext for further details.

DECLARE_TYPE_ID(0x10005a29)
| DECLARE_TYPE_ID | ( | 0x10005a29 | | ) | [inline] |
Type ID declaration. Type ID is used to make it possible to retrieve control context through MObjectProvider::MopSupplyObject interface. Destructor. Destructor is provided only to enable deletion using base class pointer. Caller should never delete control context retrieved through MObjectProvider interface.
IsCompatibleWithType(const TAknsControlContextType)
Determines whether this control context is compatible with the given derived type.
Parameters
| const TAknsControlContextType aType | Type of the derived control context class (one of the values in TAknsControlContextType). |
Reserved2()
|
TInt
| Reserved2 | ( | ) | [protected, virtual] |
SupplyMopObject(TTypeUid, MAknsControlContext *)
Returns type UID pointer that can be used in MopSupplyObject.
Parameters
| TTypeUid aId | Type UID, should be the same that was given as aId parameter of MopSupplyObject. |
| MAknsControlContext * aContext | Pointer to an MAknsControlContext instance. |
SupplySkinObject(TAknsCCObject)
Provides context specific object.
Parameters
| TAknsCCObject aObject | Type of the object to be retrieved. Possible values are defined in TAknsCCObject enumeration. |
SupplySkinParameter(TAknsCCParameter)
Provides context specific integer parameter.
Parameters
| TAknsCCParameter aParam | Type of the parameter to be retrieved. Possible values are defined in TAknsCCParameter enumeration. |
UpdateContext()
|
TInt
| UpdateContext | ( | ) | [virtual] |
Updates the control context, if necessary. This method is called by the framework before drawing with the context.
Base class implementation returns 0.
