Clicking/Hovering on marker

HaikalSyed — Mon, 25 Nov 2019 03:03:22 GMT

Hi,

I would like to add clicking and hovering functionalities on a marker.

I am currently using a SimpleMarkerSymbol to display a marker. At the moment, I can click on it and it works.

However what I would like is to have a left click that would have a different function to a right click, as well as hovering. I don't think I have seen any examples regarding this.

How I am doing it at the moment is to use onMouseClicked with identifyGraphicsOverlay function in it and later onIdentifyGraphicsOverlayStatusChanged.

Thanks!

The MouseEvent has some additional properties on it that will let you check whether it is a left or right button click - MouseEvent QML Type | Qt Quick 5.13.2

Here is some code for you to enable hovering:

import QtQuick 2.6
import QtQuick.Controls 2.2
import Esri.ArcGISRuntime 100.6

ApplicationWindow {
    id: appWindow
    width: 800
    height: 600
    title: "HoverTest"

    // add a mapView component
    MapView {
        anchors.fill: parent
        // set focus to enable keyboard navigation
        focus: true

        // add a map to the mapview
        Map {
            // add the BasemapTopographic basemap to the map
            BasemapTopographic {}
        }

        MouseArea {
            anchors.fill: parent
            hoverEnabled: true

            onPositionChanged: {
                // get mouse coordinates
                console.log(mouse.x, mouse.y, mouse.button);

                // reject mouse event so events go through to mapview
                mouse.accepted = false;
            }

            onClicked: {
                mouse.accepted = false;
            }

            onDoubleClicked: {
                mouse.accepted = false;
            }

            onPressAndHold: {
                mouse.accepted = false;
            }

            onPressed: {
                mouse.accepted = false;
            }

            onReleased: {
                mouse.accepted = false;
            }
        }
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi. Thanks for reply.

It seems that the code works for the map since the parent is the MapView.

However, not for the marker (SimpleMarkerSymbol).

I tried putting a MouseArea inside GraphicsOverlay and nothing happens.

MouseArea will only work if nested under a MapView or SceneView. If you are trying to identify an individual graphic on a mouse movement, you could try calling MapView.identifyGraphicsOverlay() on one of the mouse move signals

In MapView.identifyGraphicsOverlay(), is there anyway to detect left or right click or hovering?

Hover implies no clicking - just hovering. If you want to perform identify after a click, use the mouseClicked signal - MapQuickView Class | ArcGIS for Developers

MouseClicked will pass through a QMouseEvent object through as a parameter, and that object contains a method to determine if it was left, right, or middle button click - QMouseEvent Class | Qt GUI 5.14.0

First of all, sorry to be asking so many questions.

Secondly, this works for QML?

Sorry I sent you C++. Here are the QML links:
