Overview

How to programmatically toggle the input mode of an editor

Description

By simulating the hash (#) key event, it is possible to toggle the input mode of the currently focused editor between normal and numeric modes.
-----
#include <ptidefs.h>        // for EPtiKeyHash
    RWsSession wSess;
    User::LeaveIfError( wSess.Connect() );
    TInt wgId = wSess.GetFocusWindowGroup();
    if( wgId != KErrNotFound )
        {
        TWsEvent keypress;   
        keypress.Key()->iCode = EPtiKeyHash;
        keypress.Key()->iScanCode = 0;
        keypress.Key()->iModifiers = 0;
        keypress.Key()->iRepeats = 1;   
        keypress.SetType(EEventKeyDown);
        keypress.SetTimeNow();
        wSess.SendEventToWindowGroup( wgId, keypress );
        User::After(2000);   
        keypress.SetType(EEventKey);
        keypress.SetTimeNow();
        wSess.SendEventToWindowGroup( wgId, keypress );
        User::After(2000);   
        keypress.SetType(EEventKeyUp);
        keypress.SetTimeNow();   
        wSess.SendEventToWindowGroup( wgId, keypress );
        }

Note: On S60 3rd Edition devices, the following code requires SwEvent capability.

Note: This does not work in devices with a full keyboard.
