Porting VS2010 project in QT .
I guess, I wasn’t very clear with my earlier post so here I am explaining it again.
The issue is .. I have lots of sub Qdialog windows which when user click generates some messages. I want those messages to be on my QTablewidget of my main Application window.
Now As suggested by some members that I should look how things have done in VS2010 and try to replicate same in QT . So Here is my design .. Please let me know your suggestion /criticism.
1) vs 2010 -> On Main application window in
MESSAGE_MAP
we have
ON_MESSAGE( WM_NOTICE, OnAddMessage )
- where WM_NOTICE = WM_USER+1;
doing same in QT I need signal and slot . so Something like
connect( sender , SIGNAL(QtSingleApplication::messageReceived ( const QString &message ) ) , this , SLOT ( on_add_message( const QString & message ) );
now what should I replace here with
- ‘sender’ ? , who will be the sender in my case ?
- SIGNAL (QtSingleApplication::messageReceived ) is right ?
- Slot — there is no issue here .. I can implement that code in which I will place the message in QTable widegt in sorting order.
2) Now if I look into inner QDialog windows source code of existing project which was developed in VC++ they have something like
void Message_information::add( const SMS& message )
{
//SMS is a structure and fields are SYSTEMTIME, Enum , CString
CCriticalSection critical_section;
CSingleLock lock( &critical_section, true );
messages_.insert( message ); // where messages_ is an object std::multiset
SendMessage( dialog_->m_hWnd, WM_MULTIBOXMESSAGE, 0, 0 );
}
Now doing same in Qt
void Message_information::add( const SMS& message )
{
QMutex mutex;
mutex.lock();
messages_.insert( message ); // where messages_ is an object std::multiset
//SendMessage( dialog_->m_hWnd, WM_MULTIBOXMESSAGE, 0, 0 );
QtSingleApplication::sendMessage ( // send multiset values here );
}
- What paramemter should I Add in SendMessage? IS infact sendMessage is correct function to call?
this ‘add’ function is being called somewhere else . I know this sounds duplicate of other questions and I have looked into the link provided my some members but I am sorry I couldn’t able to grasp much. — Any suggestion or criticism might help me .. hanks a lot for al the help
