Setting a QStyledItemDelegate on a QComboBox with a QCompleter?

[AndyBrice]

I typed this question up, then I found the answer. So I thought I would submit it anyway.

I have a QComboBox with a QCompleter:

CompleterComboBox::CompleterComboBox( QWidget* parent )
: QComboBox( parent )
{
    setEditable( true );
    setInsertPolicy( QComboBox::NoInsert );
    QCompleter* completer = new QCompleter( this );
    completer->setCaseSensitivity( Qt::CaseInsensitive );
    completer->setFilterMode( Qt::MatchContains );
    completer->setCompletionMode( QCompleter::PopupCompletion );
    completer->setModel( model() );
    setCompleter( completer );
    lineEdit()->setPlaceholderText( "Type column name" );
   
   setItemDelegate( new MyStyledItemDelegate ( this ) );
}

The paint() method on the QStyledItemDelegate never gets called.

Turns out the last line should be:

   completer->popup()->setItemDelegate( new MyStyledItemDelegate ( this ) );

Hope that helps someone. My future self perhaps. ;0)
