Place widgets at specific position

[Thibaut]

Hi!

I have a very quick question.

To make things simple, the data my users will load will have some sort of events at specific time.
Each of this event is associated with a code.
I'm already able to draw a vertical line at the time of the event, and now, I want to display those codes on top of my plot at the specified time, above the lines.

Here's what I have for now:

void EventLabels::displayEvents(QVector<QVector<int>> eventToDisplay)
{
    // eventToDisplay:
    // Event Position | Event Code
 
    for (int i = 0; i < eventToDisplay.length(); i++)
    {
        QLabel *eventCode = new QLabel;
        eventCode->setText(QString::number(eventToDisplay[i][1]));
 
        eventCode->setParent(this);
 
        eventCode->move(eventToDisplay[0][1], 0);
    }
}

void EventLabels::displayEvents(QVector<QVector<int>> eventToDisplay)
{
    // eventToDisplay:
    // Event Position | Event Code

    for (int i = 0; i < eventToDisplay.length(); i++)
    {
        QLabel *eventCode = new QLabel;
        eventCode->setText(QString::number(eventToDisplay[i][1]));

        eventCode->setParent(this);

        eventCode->move(eventToDisplay[0][1], 0);
    }
}

To copy to clipboard, switch view to plain text mode 

I have to note that this function is a slot that receive data from another class. As the user can change the displayed data, the codes will change too each time the user push a button.
From what I find, this seems to be the best solution to precisely place QWidgets at specific position.
Did I miss something or is there a better way to do it?
