ArcGIS Runtime SDK for Qt:

Building AppsKoushik Hajra and Thomas Dunn

Cross-platform

apps

Agenda for today

• Intro to Qt Framework and ArcGIS Runtime SDK for Qt

• App design patterns with this SDK

• Resources for developers

• This is an intro-level tech session

What is the Qt Framework?

• Write once, run anywhere

• Builds as native C++Portable

• Cross-platform libraries

• High-level abstractionsApproach-

able

• Pre-built some platforms

• Source code availableOpen

What kind of apps can you build?

• Advanced, native mapping apps

for mobile & desktop clients

- Linux, Windows, Android, iOS and

OS X

- Take advantage of Runtime’s C++

core and GPU acceleration

• Leverage the power and versatility

of the ArcGIS platform

• Build apps that work whether

connected or disconnected

ArcGIS Runtime session tracks at DevSummit 2017

• ArcGIS Runtime SDKs share a common core, architecture and design

• Functional sessions promote common capabilities and workflows

- An Introduction to the API and Architecture

- Working with Your Portal

- Building Great User Experiences

- Styling Maps

- Working with Maps Online and Offline

- Editing Your Data Online and Offline

Shared workflows, any platform, any device

.NET iOS macOS Android Java Qt

ArcGIS Runtime core

Consider using the ArcGIS Runtime SDK for Qt

• When you are building apps for more than one O/S and want

- Same code

- Same workflow

- Access to device’s sensors

- Support of a vibrant open-source community and Qt ecosystem

• When you have in-house experience with Qt Framework, QML, JavaScript, or C++

Getting ready to write some code

• Install the Qt Framework from the Qt Company

• Log onto ArcGIS Online with your developer subscription

• Download ArcGIS Runtime SDK for Qt

• Run the installer and the post installer

App patterns

Using the C++ API

• Provides all Runtime capabilities

• Create your UI with Qt Quick (all platforms)

• Create your UI with Qt Widgets (desktop platforms)

• The C++ API provides access to Local Server (Windows and Linux only)

C++ / Qt Quick

Travel planner app

Using the QML API

• The declarative language from The Qt Company

• Declare components similarly to writing JSON or CSS

• Write procedural code as JavaScript functions

• Create UI rapidly with Qt Quick, with animation and prebuilt controls

• ArcGIS Runtime extends QML with types encapsulating ArcGIS functionality

Default properties in QML

• Declaring within a component another component of a specific type sets a specific

default property associated with that type

• Example: Map type

- Basemap – Sets the basemap property

- Viewpoint – Sets the initialViewpoint

property

- Layer - Appended operationalLayers

property (a list of layers)
