The model/view design pattern is the standard way of separating UI from business logic, especially when the data exchanged is dynamic. In a series of blog posts released in May, we presented an introduction to model/view design and provided an example of how this pattern is leveraged in Qt applications. In this webinar, we will go more in depth, illustrating model/view with a set of two QML programming examples. The first will consider the simple case where data size remains constant. The second will cover the more common situation where data size is dynamic.
This presentation and we will explore some of the more complex areas of QML and present tips, tricks, best practices and common areas of error and confusion. The material is based on real-world experience developing customer applications for mobile, embedded and desktop.

Practical QML - Key Navigation, Dynamic Language and Theme ChangeBurkhard Stubert
This is the presentation "Practical QML" that I gave at the Qt Developer Days 2013 in Berlin and San Francisco.
What topics entail the liveliest discussions when you talk to the makers of in-vehicle infotainment systems, agricultural driver terminals or set-top boxes about building QML GUIs? No, it is not about "fluid" multi-touch UIs with graphical "wow" effects, but about mundane things like key navigation, theming, and internationalisation. I'll address these three problems in my talk.
First, I’ll discuss how to navigate QML GUIs solely with a rotary knob. By turning or pushing the knob, a "cursor" is moved from one QML component or one screen to another.
Then, I'll show how to switch between different languages and between different themes at run-time.
Design Patterns help us solve problems in tried and tested ways.
Turns out they also help us understand our framework better, for framework developers also use patterns.
In these slides you'll see how Design Patterns are implemented by Qt framework, to better both understand patterns and Qt
QVariant, QObject — Qt's not just for GUI developmentICS

MDG Panel - Creating Expert Level GUIs for Complex Medical DevicesICS
Graphical User Interfaces are so pervasive and have so many different design intents that it can be hard to see the norms and evolution of norms being applied over the past couple of decades. In medical devices, more than most, tradeoffs between safety, effectiveness and pleasure-to-use, dominate the design efforts.
.
Much focus and debate has been applied to paradigms of “simple yet effective” in GUI design. The most commonly cited ideals in the Apple eco-system and skeuomorphic design concern themselves with the novice user and technology adoption. But not all products are designed for the novice user.
.
For UIs that expose advanced or unstructured feature sets to the user, the normative approach has been to compromise on the simplicity to extend the functionality. But such an approach can be incremental and muddled where a better approach might be cogent redesign.
.
We will explore the evolution of a life-saving lung transplant medical device from Tevosol that implements an expert-level GUI for clinical users. Focus will be on lessons learned and the design principles ultimately chosen.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
OpenFOAM solver for Helmholtz equation, helmholtzFoam / helmholtzBubbleFoamtakuyayamamoto1800
In this slide, we show the simulation example and the way to compile this solver.
In this solver, the Helmholtz equation can be solved by helmholtzFoam. Also, the Helmholtz equation with uniformly dispersed bubbles can be simulated by helmholtzBubbleFoam.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

"Secure Your Premises with VizMan (VMS) – Get It Now"
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Qt Model / View with QML
July 25th Webinar With Chris Probst & Ryan Hampton
Visit us at http://www.ics.com
Produced by Integrated Computer Solutions
Material based on Qt 5.12
1
2. Integrated Computer Solutions Inc. www.ics.com
What is MVC?
- Stands for Model/View/Controller
- Architectural Design Pattern used for developing user interfaces
- Separates data interactions into three separate parts
- Allows for User Interface being independently developed from business logic.
In general terms:
- Model manages the data of the user interface
- View displays the model
- The controller responds to the user input and manages the model accordingly
2
3. Integrated Computer Solutions Inc. www.ics.com
Simple QML Example
- In Qt/QML, the controller is combined with the view
- A simple approach of leveraging Model/View in Qt/QML would be
- For every value displayed, create a Q_PROPERTY
- Provide a read, write and notify signal
- Export the properties to QML, using void QQmlContext::setContextProperty
3
class simpleModel : public QObject
{
Q_OBJECT
Q_PROPERTY(int speed READ speed WRITE setSpeed NOTIFY speedChanged)
Q_PROPERTY(int temperature READ temperature WRITE setTemperature NOTIFY temperatureChanged)
QQmlApplicationEngine engine;
simpleModel aSimpleModel;
engine.rootContext()->setContextProperty("asimplemodel",&asimpleModel);
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
4. Integrated Computer Solutions Inc. www.ics.com
Model View Delegate
- Preserves Business-Logic/View separation
- Model provides data to the view
- View is the visual container displaying the data
- Delegates renders each of the instances of the
data
- Available for both Widgets and QML
4
5. Integrated Computer Solutions Inc. www.ics.com
Other Simple Approaches
- Creating the Model in QML
- Standard QML models
- ListModel - simple hierarchy of QML types
- ObjectModel - Visual items, no delegate needed
- XmlListModel - XML data source
- Integer - read only, the model has no data roles
- Object instances - properties of the object are the roles
- JavaScript array - read only, no need for dynamic model updates
5
ListModel {
id: fruitModel
ListElement {
name: "Apple"
cost: 2.45 }
ListElement {
name: "Orange"
cost: 3.25 }
… }
6. Integrated Computer Solutions Inc. www.ics.com
Example: Contact List
● Create a ListModel
○ Fill it with ListElement objects, each with:
■ A name property
■ A file property referring to an image
● Add a ListView and a Component
to use as a delegate
● Add header, footer and highlight
properties to the view
6
7. Integrated Computer Solutions Inc. www.ics.com
Examples of QML Views - ListView
7
- Based on a Flickable area
- It uses a model, instantiates a delegate and
between the delegates, there can be spacing
- Most commonly used
- Can be horizontal or vertical
ListView {
model: mymodel
delegate: numberDelegate
spacing: 5
}
}
8. Integrated Computer Solutions Inc. www.ics.com
Examples of QML Views - GridView
8
- Based on a Flickable area
- It uses a model, instantiates a delegate and
between the delegates, there can be spacing
- Places the data into a two-dimensional grid,
left-to-right or top-to-bottom
See $QTDIRExamplesQt-5.11.2quickviews
9. Integrated Computer Solutions Inc. www.ics.com
Examples of QML Views - PathView
9
- Lays out the data along an arbitrary path
- Most powerful, but also the most complex
- Requires the path property to be set
- Paths are specified using the Path QML
object
See $QTDIRExamplesQt-5.11.2quickviews
10. Integrated Computer Solutions Inc. www.ics.com
What about the Delegate?
10
- Appearance of each individual item
- Can be a Component or a QML file
See $QTDIRExamplesQt-5.11.2quickviews
Column {
spacing: 2
Repeater {
model: 10
delegate: BlueBox {
width: 100
height: 32
text: index
}
}
}

A Model in C++ : A Simple Approach
11
QStringList dataList;
dataList.append("Item 1");
dataList.append("Item 2");
dataList.append("Item 3");
dataList.append("Item 4");
QQmlApplicationEngine engine;
engine.rootContext()
QQmlContext *ctxt = view.rootContext();
ctxt->setContextProperty("myModel",
QVariant::fromValue(dataList));
ListView {
width: 100; height: 100
model: myModel
delegate: Rectangle {
height: 25
width: 100
Text { text: modelData }
}
}
● Model can be specified QStringList, QVariantList, QObjectList
12. Integrated Computer Solutions Inc. www.ics.com
QAbstractListModel - What to reimplement?
12
● provide implementations of the QAbstractListModel::rowCount() and
QAbstractListModel::data() functions.
QVariant Mp3ListModel::data(const QModelIndex &index, int role) const
{
if (!index.isValid())
return QVariant();
Mp3Item *mp3Item = m_mp3Items.at(index.row());
switch (role) {
case DoneRole:
return QVariant(mp3Item->download.finished());
case UrlRole:
return QVariant(mp3Item->download.url().toString());
case ProgressRole:
return QVariant(mp3Item->download.progress());
case ErrorRole:
return QVariant(mp3Item->download.error());
return QVariant();
}
int Mp3ListModel::rowCount(const QModelIndex &parent)
const
{
if (parent.isValid())
return 0;
return m_mp3Items.size();
}
13. Integrated Computer Solutions Inc. www.ics.com
QAbstractListModel - If user can change data?
13
● Provide implementations of the QAbstractListModel::setData() functions.
bool Mp3ListModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
if (role == SelectedRole) {
if (index.row() < 0 || index.row() >= m_mp3Items.size())
return false;
if (m_mp3Items.at(index.row())->selected == value.toBool())
return false;
m_mp3Items.at(index.row())->selected = value.toBool();
dataChanged(index, index);
return true;
}
return false;
}
14. Integrated Computer Solutions Inc. www.ics.com
QAbstractListModel - A Note on Roles
14
● Along with the QModelIndex, a role is simply an additional selector to
access data in your model.
class Mp3ListModel : public QAbstractListModel
{
Q_OBJECT
public:
explicit Mp3ListModel(QObject *parent = nullptr)
noexcept;
enum {
SelectedRole = Qt::UserRole,
DoneRole,
UrlRole,
... };
QHash<int, QByteArray>
Mp3ListModel::roleNames() const
{
QHash<int, QByteArray> roles;
roles[SelectedRole] = "selected";
roles[DoneRole] = "done";
roles[ProgressRole] = "progress";
roles[UrlRole] = "url";
roles[ErrorRole] = "error";
return roles;
}
ListView {
….
delegate: RowLayout {
spacing: 10
CheckBox {
checked: model.selected
onClicked: model.selected = checked
}
Label {
Layout.fillWidth: true
text: model.error ? qsTr("Error on
Download") : model.url
elide: Text.ElideLeft
...
}
15. Integrated Computer Solutions Inc. www.ics.com
QAbstractListModel - Notifying the View of
Changes
15
● Emit the signal:
void QAbstractItemModel::dataChanged(const QModelIndex&topLeft,
const QModelIndex &bottomRight, const QVector<int> &roles = ...)
m_mp3Items.at(index.row())->selected = value.toBool();
emit dataChanged(index, index);
16. Integrated Computer Solutions Inc. www.ics.com
Hooking the Model up to the View
16
#include <mp3listmodel>
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling);
QQmlApplicationEngine engine;
Mp3ListModel mp3ListModel(downloadDirUrl);
engine.rootContext()->setContextProperty("mp3ListModel"), &mp3ListModel);
qmlRegisterUncreatableType<Mp3ListModel>("DownloadManager", 1, 0,
"Mp3ListModel", "Mp3ListModel should not be created in QML");
engine.load("qrc:/main.qml"); // Load blocks
return app.exec();
}
ListView {
anchors.fill: parent
model: mp3ListModel
delegate: Mp3Item {
width: parent.width
}
}

Summary: Model / View
Qt Model / View in a nutshell
● A model provides data for a view
● A view displays the data from the model
● Similar to the Model / View / Controller design pattern
○ But combine the controller with the view
Why Model / View?
● Isolate business logic from UI logic
● Create UI components that are independent
○ Easier Development
○ Easier Testing
○ Easier Maintenance
● More Reuse
○ Reuse your UI logic across multiple views
○ Models can be reused for different views
18
19. Integrated Computer Solutions Inc. www.ics.com
Summary: Model / View Components
Model:
● Interface to business logic data
● Emits signals when data changes or is appended
● Many common model types are provided by Qt
● C++: QStringList, QVariantList, QAbstractItemModel subclass
● QML: an integer, JavaScript array, ListModel, XmlListModel
View:
● Displays the data structure
● Handles the user interaction with the data
● Qt provides many view types with model support
● QML: ListView, GridView, PathView, TableView (new)
Delegate:
● Items in a view are rendered and edited by delegates
● The view expects a Component for its delegate property
● Model items are accessible through the index property
19
21. Integrated Computer Solutions Inc. www.ics.com
Summary: Model Types
21
● Standard QML models
○ ListModel - simple hierarchy of QML types
○ ObjectModel - Visual items, no delegate needed
○ XmlListModel - XML data source
○ Integer - read only, the model has no data roles
○ Object instances - properties of the object are the roles
○ JavaScript array - read only, no need for dynamic model updates
● C++ models (must be implemented in C++ before use)
○ More complex but more fine-tuned control over data access
○ QStringList, QVariantList, QObjectList, QAbstractItemModel (and subclasses)
○ Subclass QAbstractItemModel for complex data-sets
