QComboBox with QCompleter, lineedit -> selectAll

the_

Hi all,

For a large dropdown (250+ items) I used QCompleter for a searchable QCombobox. Searching and autocompletion works fine, but now I want to select all text when I click in the textfield.

As far as I correctly understand http://doc.qt.io/qt-5/qlineedit.html#selectAll , the text is highlighted and deleted if I start typing.

To use it I installed an event filter on the QLineEdit

//thiscombo is a valid QWidget
QLineEdit *le = new QLineEdit(thiscombo);
le->setObjectName("Completer_1206");
le->installEventFilter(this);
apcompleter = new QCompleter(le);
connect(apcompleter,SIGNAL(activated(QString)),this,SLOT(completerslot(QString)));
thiscombo->setLineEdit(le);
thiscombo->setAutoCompletion(false);
thiscombo->setInsertPolicy(QComboBox::NoInsert);
le->setCompleter(apcompleter);
apcompleter->setCaseSensitivity(Qt::CaseInsensitive);
apcompleter->setCompletionMode(QCompleter::PopupCompletion);
apcompleter->setModel(new QStringListModel(thiscombo));

//inside the ::eventFilter(QObject,QEvent)
if(object->objectName() == "Completer_1206" && event->type() == QEvent::MouseButtonPress) {
        qDebug() << object;
        QLineEdit *l = dynamic_cast<QLineEdit *>(object);
        l->selectAll();
        qDebug() <<l->selectedText() << l->hasSelectedText();


    }

So on MouseClick I get the selectedText and hasSelectedText is true, but the text is not highlighted, and when i start typing, the text is inserted at the cursor position.

Is there anything wrong in the way I try to highlight the text?

Thanks in advance

Well the solution is very simple.

The last line in my eventFilter is

QWidget::eventFilter(object,event);

So it also does what the widget usually does on mouse click.

a simple

return true;

at the end of my if and the text is highlighted.
