Symbian/C++ Code and Examples
Areas of interest
Base/System - S60/Symbian C++
S60 Platform: Log Example
This C++ application demonstrates the usage of the Log Engine API provided by Symbian. The API is used to record events of interest to the user, of which they may not be immediately aware, or which are of high importance since costs are incurred, such as telephone calls. These events can be retrieved by a viewer application and displayed to the user. The Log Engine API is supported from S60 2nd Edition onwards. In the updated version, the timestamp offset of the log events has been corrected, backup & restore and scalability support has been added, and the application views have been simplified.
S60 Platform: Chinese Display Example
This C++ application demonstrates how to display Chinese characters
from resource files. The application supports internationalization and localization. In the
updated version also the context-sensitive help has been added.
The application supports following languages:
English, Taiwan Chinese, Taiwan English,
HongKong Chinese, HongKong English,
Mainland Chinese, and Mainland English.
Main classes: TFontSpec, CCnvCharacterSetConverter
S60 Platform: Descriptor Example v2.0
This C++ code example demonstrates how to use descriptors (Symbian OS strings) and related APIs. The example is an S60 application that is used to run one or all example methods. The methods write a log to the screen or to a file that demonstrates the results of different statements. Main classes: TBuf, HBufC, RBuf.
S60 Platform: ECom Plug-In Examples v2.0
This package includes two C++ code examples demonstrating how to create and
use an ECom plug-in from a client application. ECom_Shape draws different
figures and ECom_ Calculator performs calculation for two numbers using the
ECom plug-in component. The examples consist of a custom ECom interface, a
DLL plug-in component with actual implementations for the interface, a resolver
(either a default or custom resolver), and a simple GUI client that uses the
interface. Main classes: REComSession, TEComResolverParams, CEikLabel,
CEikEdwin, TResourceReader, CResolver, TImplementationProxy.
S60 Platform: Power and Resource Management Example v2.0
This updated C++ code example demonstrates the APIs that are available for
figuring out battery, charger, and network status. It also demonstrates some of the
techniques and principles described in the document S60 Platform: Effective
Power and Resource Management (available at www.forum.nokia.com), including
the use of active objects and multiple threads. It is recommended that the
document is read before studying the example.
Main classes: CTelephony, RSystemAgent, TSysAgentEvent, CIdle, CActive.
S60 Platform: Document Handler Example
This C++ example demonstrates how to use the Document Handler and the Recognizer to open and handle certain file types in a dedicated application. The example consists of three components: a caller application trying to open a specific file, a recognizer (a dll component implemented as an ECom plugin from S60 3rd Edition onwards) detecting the file extension, and a document handler opening the file. Note that for the recognizer, a developer certificate is needed due to its ProtServ capability requirement. Usage of the document handler is described in the S60 Platform: Document Handler API Developer's Guide document, available at www.forum.nokia.com. Main classes: CDocumentHandler, CApaDataRecognizerType.
S60 Platform: FEP Example v2.0
This C++ code example demonstrates how to create and install a custom Front End Processor (FEP). It consists of two components: FepSetup, which can be used to install/switch the active FEP, and FepExample, which contains the actual FEP implementation. FepExample contains a sample multi-tap input engine, which modifies the behavior of the mobile phone's numeric keys. Note that because the active FEP is actually loaded by all applications, platform security (introduced in S60 3rd Edition) requires ALL-TCB capabilities, and thus the FepExample component has to be signed using the Manufacturer Approved Developer Certificate. Note also that FEP might not be compatible with all S60 applications. The known issues are described in the release notes in the example package. The example includes an AknEditStateIndicator.h header that is needed to define MAknEditingStateIndicator. The header was not available in the S60 SDKs until S60 3rd Edition, Feature Pack 1. Main classes: CCoeFep, CCoeFepPlugIn, CFepGenericGlobalSettings, MAknEditingStateIndicator.
S60 Platform: Time Zone Localizer Example

S60 Platform: Localization Example
This C++ example demonstrates how to localize an application to adapt to the selected phone language. The application has two sets of localized strings (English and German) for the application name, labels, text, and image. The application also presents number, currency, date, and time localization, in which the TLocale method is used to localize them even if the selected phone language is none of the two application languages. Main classes: TLocale, TTime.
