QTextBrowser / C++ append clickable text

I am new in using QT and i have a problem. I want to check a 2D circuit layout and I want to output warnings or errors on a window. Each warning or error should contain X and Y coordinates and when I click on a warning it should call a function which navigates me to the faulty position in the layout(coordinate system).

Is there a way to make a text funcioning ? I hope you understood my problem.

Yes, it can be implemented with the QTextBrowser, but there will be a lot of code and no benefits. There is a faster, simpler and more scalable way.

Just use QListWidget and set user data (QListWidgetItem::setData) to each item, that will contain coordinates (you can use QPoint for this).

Create QListWidget and connect some slot or function to the signal QListWidget::itemClicked:

QListWidget* log = new QListWidget;
QObject::connect(log, SIGNAL(itemClicked(QListWidgetItem*)), onItemClicked(QListWidgetItem*));

Then, when you recieve new warning (ex. in QString called log_string) with coordinates (called x and y):

QListWidgetItem* line = new QListWidgetItem(log_string, log);
line->setData(Qt::UserRole, QVariant(QPoint(x, y)));
log->addItem(line);

Now you only need to process coordinates in the proper way in the slot or function connected to the QListWidget::itemClicked signal:

void onItemClicked(QListWidgetItem* item)
{
  const QPoint coord = item->data(Qt::UserRole).toPoint();
  // process coord.x() and coord.y()
}
