ArcGIS OnClick MouseEvent Question.

Question

Hello,

I have this piece of code where I can statically add points to the map

void MainWindow::populatePoints(QList<Point>& locations)

{

locations.clear();

locations.append(Point(-11853242.850239, 3922136.795369, SpatialReference::webMercator()));

}

But..what I am trying to figure out is how can I make OnClick event, so every time I click
on the map, it will append a point to the map. I am a fairly new programmer and any guidance to solve
this problem would be much appreciated.

Thank you,
Armando

You'll want to connect up to the mouseClicked signal coming off the MapView. This will pass through a QMouseEvent, which can be used to create a Point. You can then add that Point as a Graphic. For example: connect(m_mapView, &MapGraphicsView::mouseClicked, this, [this](QMouseEvent& mouseEvent) { // obtain the map point const double screenX = mouseEvent.x(); const double screenY = mouseEvent.y(); Point newPoint = m_mapView->screenToLocation(screenX, screenY); // create graphic Graphic* graphic = new Graphic(newPoint, this); // add to overlay m_graphicsOverlay->graphics()->append(graphic); }‍‍‍‍‍‍‍‍‍‍‍‍‍
