QTextEdit Accessibility doesn't work!

payman

I have a simple GUI with a single QTextEdit. I want to change the text of textEdit object whenever some keys pressed by user.

The problem is that when I change the text using QTextEdit::setText(), it seems that screen reader receives no event at all and therefore it doesn't read the new text for user.

I have tried QTextEdit::Update(), QtextEdit::setFocus(), QAccessibleTextUpdateEvent and QAccessible::updateAccessibility(), but none of them works!

My event filter code is like this :

bool MainWindow::eventFilter(QObject *watched, QEvent *event)
{
    if(watched == ui->textEdit && event->type() == QEvent::KeyPress)
    {
        QKeyEvent *key_event = static_cast<QKeyEvent *>(event);
        QString str = "Hello! " + QString::number(counter++);
        if(key_event->key() == Qt::Key_Down)
        {                    
            ui->textEdit->setText(str);

            return true;
        }
    }

    return false;
}

Also I've noticed that if I change the cursor position after changing the text, then screen reader reads the new text!

My code to change cursor position :

bool MainWindow::eventFilter(QObject *watched, QEvent *event)
{
    if(watched == ui->textEdit && event->type() == QEvent::KeyPress)
    {

        QKeyEvent *key_event = static_cast<QKeyEvent *>(event);
        QString str = "Hello! " + QString::number(counter++);
        if(key_event->key() == Qt::Key_Down)
        {
            int pos =  ui->textEdit->textCursor().position();

            ui->textEdit->setText(str);

            if( pos == 0)
            {
                ui->textEdit->moveCursor(QTextCursor::End);
            }
            else
            {
                ui->textEdit->moveCursor(QTextCursor::StartOfLine);
            }
            return true;
        }
    }

    return false;
}

But the above code works only with KEY_DOWN and if I change the key to something else then Orca goes silent again!!!

Any idea to solve this issue?

I'm using QT 5.10, Ubuntu 16.04 and Orca 3.25.90 .

I knew about the issues on Windows but not on Linux.
