Hi

Completer pop up is not displayed , while line edit text is empty

code

completer = new QCompleter(wordList, ui->lineEdit);

completer->setCompletionMode(QCompleter::PopupCompletion);
ui->lineEdit->setCompleter(completer);
ui->lineEdit->completer()->complete();
even

ui->lineEdit->completer()->popup()->show(); is not helping me to show completer popup



Thanks

If you are are calling complete() in constructor then you can notice that the popup actually appears for a moment just before the main window. Best solution would be probably this:

Code:

---

QAction* action = new QAction(this);
action->setShortcut(QKeySequence(Qt::CTRL + Qt::Key_Space));
ui->lineEdit->addAction(action);
connect(action, SIGNAL(triggered()), completer, SLOT(complete()));

---

But if you really want the popup to appear together with main window then this could do the trick:

Code:

---

...
   QTimer::singleShot(250, this, SLOT(func()));
}
 
void MainWindow::func()
{
    completer->complete();
}
