The QService namespace contains miscellaneous identifiers used throughout the Qt Service framework library.
Defines the scope to be used when accessing services. Note that Symbian does not distinguish scopes and therefore UserScope and SystemScope may be used interchangeably.
| Constant | Value | Description |
|---|---|---|
| QService::UserScope | 0 | When adding and removing services, uses a storage location specific to the current user. When searching for services and interface implementations, first searches in the user-specific location; if the service or interface implementation is not found, searches in the system-wide storage location (if the user has sufficient permissions to do so). |
| QService::SystemScope | 1 | When adding and removing services, use a system-wide storage location accessible to all users. When searching for services and interface implementations, search only in the system-wide storage location. |
Defines the type of the service
| Constant | Value | Description |
|---|---|---|
| QService::Plugin | 0 | This denotes that the service is plug-in based. |
| QService::InterProcess | 1 | This denotes that the service is deployed using IPC mechanisms available on the current platform, such as DBus or local sockets. |
Defines the unrecoverable IPC error of the service
| Constant | Value | Description |
|---|---|---|
| QService::ErrorUnknown | 0 | An unknown IPC error. |
| QService::ErrorServiceNoLongerAvailable | 1 | Indicates that the service is no longer available. |
| QService::ErrorOutofMemory | 2 | Indicates that the service is out of memoruy. |
| QService::ErrorPermissionDenied | 3 | Indicates that the permission of this service is denied. |
| QService::ErrorInvalidArguments | 4 | User uses invalid argument for this service. |
