Overview

This code snippet is one of the series of snippets that demonstrate how to implement support for international diversity. This snippet shows how to select a bitmap according to the locale settings of the device.

MMP file

The following libraries are required:

LIBRARY fbscli.lib

Resource files

data\[app].rls:

#ifndef __APP_LOC__
#define __APP_LOC__
 
#ifdef LANGUAGE_01 // Language code for UK
#include "..\data\app.l01"
#elif defined LANGUAGE_03 // Language code for German
#include "..\data\app.l03"
#endif
 
#endif // __APP_LOC__

Declare the location of the "English" bitmap into data\[app].l01:

// The paths in the following string are different for 3rd & 2nd Ed. platforms
#ifdef EKA2
#define qtn_loc_bmpfile "%U\\resource\\apps\\Bitmap_01.mbm"
#else
#define qtn_loc_bmpfile "%U\\system\\apps\\Localization\\Bitmap_01.mbm"
#endif

Declare the location of the "German" bitmap into data\[app].l03:

// The paths in the following string are different for 3rd & 2nd Ed. platforms
#ifdef EKA2
#define qtn_loc_bmpfile "%U\\resource\\apps\\Bitmap_03.mbm"
#else
#define qtn_loc_bmpfile "%U\\system\\apps\\Localization\\Bitmap_03.mbm"
#endif

In the resource file of the application (data\[app].rss), create a bitmap resource from the localized string:

RESOURCE TBUF256 r_loc_bmpfile { buf=qtn_loc_bmpfile; }

Source file

#include <stringloader.h>
// Find the drive where the application has been installed
TParse parse;
parse.Set(Application()->AppFullName(), 0, 0);
 
// Load the name of the bitmap from the resource file
HBufC* bmpFile = StringLoader::LoadLC(R_LOC_BMPFILE, parse.Drive());
 
// Create and load the bitmap
CFbsBitmap* bitmap = new (ELeave)CFbsBitmap;
CleanupStack::PushL(bitmap);
 
// Load the first bitmap (index 0) from a multi-bitmap file
User::LeaveIfError(bitmap->Load(*bmpFile, 0));
 
CleanupStack::Pop(bitmap);
 
// Draw the bitmap onto the screen
// ...
 
CleanupStack::PopAndDestroy(bmpFile);

Postconditions

A bitmap is selected according to the locale settings of the device.
