    avkon.hrh & w32std.h Errors on include

    Hello! I am working on a project for Symbian S60 v3 using Qt 4.7.3 and I need to intercept events such as Red Key Pressed. I have found some examples on how to do it, but when I try it myself I get the following errors:

    mainwindow.h:5: error: avkon.hrh: No such file or directory
    mainwindow.h:6: error: w32std.h: No such file or directory
    mainwindow.h:34: error: ISO C++ forbids declaration of 'TWsEvent' with no type
    mainwindow.h:34: error: expected ',' or '...' before '&' token
    I have added the path to these files in my .PRO file:
    INCLUDEPATH += C:\\QtSDK\\Symbian\\SDKs\\Symbian1Qt473\\epoc32\\include

    This seems to have solved the problem, but then I get the following errors

    e32des16.h:691: error: #error no typedef for __TText
    e32def.h:872: error: 'Int64' does not name a type
    e32def.h:883: error: 'Uint64' does not name a type
    e32const.h:860: error: 'TInt64' does not name a type
    e32const.h:882: error: 'TUint64' does not name a type
    e32cmn.h:41: error: 'IMPORT_C' does not name a type
    e32cmn.inl:2537: error: no matching function for call to 'TBufBase8::TBufBase8(int)'

    After declaring Int64, Uint64, TInt64 and TUint64 some of the messages disappear, but I don't know how to solve the others.
    I am asking if someone knows what the problem is and how to solve it.
    Here is the code for my app:

    .PRO file:
    # Add files and directories to ship with the application 
    # by adapting the examples below.
    # file1.source = myfile
    # dir1.source = mydir
    DEPLOYMENTFOLDERS = # file1 dir1
    symbian:TARGET.UID3 = 0xE09286BD
    # Smart Installer package's UID
    # This UID is from the protected range 
    # and therefore the package will fail to install if self-signed
    # By default qmake uses the unprotected range value if unprotected UID is defined for the application
    # and 0x2002CCCF value if protected UID is given to the application
    #symbian:DEPLOYMENT.installer_header = 0x2002CCCF
    # Allow network access on Symbian
    symbian:TARGET.CAPABILITY += NetworkServices
    # If your application uses the Qt Mobility libraries, uncomment
    # the following lines and add the respective components to the 
    # MOBILITY variable. 
    # CONFIG += mobility
    # MOBILITY +=
    SOURCES += main.cpp mainwindow.cpp
    HEADERS += mainwindow.h
    FORMS += mainwindow.ui
    INCLUDEPATH += C:\\QtSDK\\Symbian\\SDKs\\Symbian1Qt473\\epoc32\\include

            attribute = Qt::WA_AutoOrientation;

    Thank you in advance!

    Please post exactly the error that you get. We cannot help you if you just say "some of the messages disappear, but I don't know how to solve the others".
    You are also missing ";" after the swicth() command.
    Best regards.
