QML was designed to build apps

QML

• A User Interface framework and declarative language- Collection of UI components- Model-view support- JavaScript engine- Animation framework- Properties- Property bindings- Can talk to C++

• A bit like CSS, HTML and JSON

Rectangle{id : rectcolor : “red”onColorChanged : titleText.text = “We changed the color”

}Text{

Id : titleTextText : “My First Map”

}Map{

id : myMaponStatusChanged : rect.color = “green”mapScale : rect.colorChanged ? 40000 : 10000

}

Esri QML API

About the QML API in ArcGIS Runtime SDK for Qt

• No C++ development is required• JavaScript skills come in handy• You can use Qt QML Types with Esri’s

- States, Transitions

• Functionally, almost equivalent to CPP API *

* No LocalServerNo GeoprocessingNo Military Standard Symbology

What You Need for Development

• Windows + Visual Studio, Linux, or Mac OS • Qt SDK and Qt Creator from The Qt Company – http://qt.io

• Building for Android devices? - The Android SDK & NDK bits- Ant- JDK (8)- Do NOT WORRY – you don’t need to know how to use these!

• Building for iOS devices? - Xcode- Apple Developer Subscription

• ArcGIS Runtime SDK for Qt - http://developers.arcgis.com/qt
