In many cases, a mail server may accept a message, only to have delivery fail at a later time; read back over the foregoing Multiple Hops section, and imagine how many possibilities of failure there are before that message reaches its destination!

Figure 12-3. The TextDialog object hierarchy Parts of the implementation of the TextDialog class can be seen in Listing 12-38. You can see the constructor that sets up the user interface, connects the button box to the buttonClicked slot, and initializes the counter. The buttonClicked slot is also shown in the listing. The slot is invoked for clicks on both the Close and Reset buttons. By checking the role of the abstract button, you can determine whether Reset was clicked. In that case, the list widget is cleared from any list items it might contain.

Sometimes it is nice to know about what kind of messages a remote SMTP server will accept For instance, most SMTP servers have a limit on what size message they permit, and if you fail to check first, then you may transmit a very large message only to have it rejected when you have completed transmission In the original version of SMTP, a client would send a HELO command as the initial greeting to the server A set of extensions to SMTP, called ESMTP, has been developed to allow more powerful conversations ESMTP-aware clients will begin the conversation with EHLO, which signals an ESMTPaware server to send extended information This extended information includes the maximum message size, along with any optional SMTP features that it supports However, you must be careful to check the return code Some servers do not support ESMTP.

Listing 12-38. The user interface handling part of the TextDialog TextDialog::TextDialog() : QDialog() { ui.setupUi( this ); connect( ui.buttonBox, SIGNAL(clicked(QAbstractButton*)), this, SLOT(buttonClicked(QAbstractButton*)) ); count = 0; } void TextDialog::buttonClicked( QAbstractButton *button ) { if( ui.buttonBox->buttonRole( button ) == QDialogButtonBox::ResetRole ) ui.listWidget->clear(); } The remaining part of the TextDialog class implementation is the showText slot. It can be seen in Listing 12-39 and is almost identical to the write slot of the TextDevice class shown in Listing 12-34. All this shows is that there is no difference in communicating between two QThread objects and communicating between QThread objects and the main thread. The same rules apply, and the same limitations still exist. Listing 12-39. The showText slot of the TextDialog void TextDialog::showText( TextAndNumber tan ) { QMutexLocker locker( &mutex ); ui.listWidget->addItem( QString( "Call %1 (%3): %2" ) .arg( count++ ) .arg( tan.text ) .arg( tan.number ) ); } The main function starting the threads and showing the dialog has not changed much from Listing 12-33, except that the TextDevice has been replaced by a TextDialog. The dialog is now started as a thread but shown before QApplication::exec is started. When that call returns, the TextThread threads are stopped and waited for before the return value from the exec call is returned. The application can be seen in action in Figure 12-2. Notice that you can move up and down in the list widget and clear it independently of the two threads; they will keep on adding items in parallel with anything that happens in the main thread.
