Item Delegate - Relay a signal to editor widget

[LynneV]

Hello - I know this *should* work, but I can't seem to figure it out. I have a QTreeView with a complex ItemDelegate that is made up of several widgets inside a frame. I want to insert some text(the name of a database field) into one of those widgets on a double-click in another TreeWidget ( a list of database fields in a docking window). I have done this:

connected the double-click signal from the docking window TreeWidget to the ItemDelegate:

connect( this->getFieldsList(), SIGNAL( itemDoubleClicked( QTreeWidgetItem *, int) ), del, SLOT( insertText( QTreeWidgetItem *, int ) ) );

connect( this->getFieldsList(), SIGNAL( itemDoubleClicked( QTreeWidgetItem *, int) ), del, SLOT( insertText( QTreeWidgetItem *, int ) ) );

To copy to clipboard, switch view to plain text mode 

where del is the item delegate. This works fine.

defined a slot in the item delegate called insertText as:

void RWDelegate::insertText( QTreeWidgetItem *item, int col )
{
    QString qualified_name = item->parent()->text( col ) +"."+ item->text( col ); 
    int cnt = receivers( SIGNAL(textToInsert( const QString & ) ) );
    emit textToInsert( qualified_name );
}

void RWDelegate::insertText( QTreeWidgetItem *item, int col )
{
    QString qualified_name = item->parent()->text( col ) +"."+ item->text( col ); 
    int cnt = receivers( SIGNAL(textToInsert( const QString & ) ) );
    emit textToInsert( qualified_name );
}

To copy to clipboard, switch view to plain text mode 

the number of receivers is always 0, by the way

defined a signal in the item delegate as:

signals:
    void textToInsert( const QString & qualified_name  );

signals:
    void textToInsert( const QString & qualified_name  );

To copy to clipboard, switch view to plain text mode 

connected the specific widget that should receive the textToInsert signal in createEditor as:

RWFilterEdit *query_filter = new RWFilterEdit( query_open );  
                bool isconnect = connect( this, SIGNAL( textToInsert( const QString &)), query_filter , SLOT( Inserter( const QString  &) ) );

RWFilterEdit *query_filter = new RWFilterEdit( query_open );  
                bool isconnect = connect( this, SIGNAL( textToInsert( const QString &)), query_filter , SLOT( Inserter( const QString  &) ) );

To copy to clipboard, switch view to plain text mode 

the variable isconnect returns true

defined a slot in the item delegate widget class (RWFilterEdit) as:

public slots:
    void Inserter( const QString & qualified_name );

public slots:
    void Inserter( const QString & qualified_name );

To copy to clipboard, switch view to plain text mode 

I can see the signal get emitted when debugging... but it never hits a break point in the Inserter slot. I'm processing some other signals from other widgets - but they're Qt signals (eg. currentIndexChanged) and they work fine. What am I missing???

Oh.. also a follow on question -- I hope this isn't a silly one -- why does Intellisense show the QString class as type" static int RWDelegate::QString" in my idem delegate? Other Qt classes are shown as (example) "class QTreeView"? Just curious.
