ArcGIS Runtime for Qt:Hit the ground running!

withThomas Dunn and Koushik Hajra

What if ...?

Agenda for today

▪ Intro to Qt, QML and Runtime

▪ Qt Widgets (C++) development

▪ Qt Quick (QML) development

This is an intro-level tech session

What is Qt?

• Cross-platform libraries• High-level abstractionsEasy

• Write once, run anywhere• Builds as native C++Portable

• Pre-built platforms• Source codeOpen

http://qt.io

Qt Creator

▪ The IDE for Qt development

▪ Use Qt Creator on Linux, OS X or Windows

▪ Qt Creator comes with the Qt SDK from the Qt Company

http://www.qt.io/download/

What is ArcGIS Runtime SDK for Qt?

▪ Build advanced mapping apps for mobile & desktop clients

▪ Build apps that leverage the ArcGIS platform

▪ Build C++ apps for Linux and Windows

▪ Build QML apps for Linux, Windows, Android, iOS and OS X

▪ Build natively on top of Runtime’s C++ core and GPU acceleration

▪ Build apps that are connected to network services or disconnected

Qt Widgets ( C++ )development

Map layers

Layers are added to the map in order, bottom-to-top

Graphics layers: live / temporary data:Vehicles, people, events

Basemap layer: spatial contextImagery, topography

Operational layers: dynamic featuresFacilities, buildings, zones, networks

Where do I get data?

▪ Online Services: access these via a URL– ArcGIS Online: your organizations data or data available to the public

▪ http://services.arcgisonline.com/ArcGIS/rest/services

▪ Local Content: author packages and deploy them with your app– Use a tile package as a high performance base map layer– Query from a local map service build from a map package– Geocode using locator files

Task-based framework for asynchronous operations

1. Construct a task object

2. Provide parameters

3. Connect slots for completion

signals

4. Execute task

5. Grab results in slot when task

completes

Some Runtime tasks:o Locator (geocoding) o Routing o Geoprocessingo Geodatabase synco Findo Queryo Identify featureso Find closest facilityo Calculate service areao Tile cache generation

Qt Quick ( QML )Development

What is QML?

▪ The language for the Qt Quick product from The Qt Company

▪ A declarative language for building cross-platform apps

▪ Declaring components is similar to writing JSON or CSS

▪ Writing functions is similar to writing JavaScript

▪ Easy to read, easy to write

▪ Create UI rapidly with animation and prebuilt controls

ArcGIS Runtime and QML

▪ Extends QML by adding QML types with much of the functionality of ArcGIS Runtime C++ API

QML apps

Demo

Licensing levels

▪ DeveloperAll functionality available while you develop your app (with a developer account)Displays map watermark and debug messages to the console

▪ BasicThe basics for online app development, that is, all functionality except– Offline locators - Offline routing – Offline editing - Local geodatabase sync operations with an upload

▪ StandardAll functionality
