Back by popular demand, we invite you to another informative webinar on OpenGL, a powerful, low-level graphics toolkit allowing access to accelerated GPU and hardware. Learn the many aspects of OpenGL development where Qt provides advanced interfaces to let developers focus on tasks instead of dealing with repetitive and error-prone, platform dependent issues.
This revised version the OpenGL webinar from last summer, will present information on the differences and the upgrade possibilities available for Qt-OpenGL applications converting from Qt 4x to Qt 5. In addition, we will touch upon best practices when converting legacy, fixed pipeline applications to modern OpenGL using Qt5.
The next version of Qt adds a framework for defining and executing hierarchical finite state machines in Qt applications. With Qt State Machines you can effectively model how components react to events over time; these state machines are a natural extension to Qt's event-driven programming model. State machines allow you to express the behavior of your application in a more rigid, explicit way, resulting in code that's easier to test, maintain and extend. This session presents the core concepts and functionality of Qt State Machines.

There is ongoing confusion, and some contention, over the right way to use the QThread class. Part of the confusion comes from the uniqueness of QThread, which is significantly different from other threading classes. There are two valid patterns of QThread use, and each pattern is best suited for different use cases. Errors will arise when mixing these two patterns, or applying them inappropriately.
This presentation will look at different patterns of threading in general, and examine in detail the two usage patterns for QThread. This talk will also cover how QThread works inside, how to communicate between threads, provide examples, and point out the pitfalls to avoid.
After an overview of Qt and its tools, a Hello World application quickly demonstrates the basic principles.

At the end, the foundations of the meta-object system and its implications on memory management are explained.
This module follows up the introduction in the "Software Development with Qt" module, plus the Quickstart slides.
Eos - Efficient Private Delegation of zkSNARK proversAlex Pruden
Succinct zero knowledge proofs (i.e. zkSNARKs) are powerful cryptographic tools that enable a prover to convince a verifier that a given statement is true without revealing any additional information. Unfortunately, existing systems for generating zkSNARKs are expensive, which limits the applications in which these proofs can be used.
This new work (presented by co-author Pratyush Mishra) achieves security against malicious workers without relying on heavyweight cryptographic tools. We implement and evaluate our delegation protocols for a state-of-the-art zkSNARK in a variety of computational and bandwidth settings, and demonstrate that our protocols
are concretely efficient. When compared to local proving, using our protocols to delegate proof generation from a recent smartphone (a) reduces end-to-end latency by up to 26×, (b) lowers the delegator’s active computation time by up to 1447×, and (c) enables proving up to 256× larger instances

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

20. QScriptValue class
• Represents a QtScript (JavaScript) value
• Undefined
• Null
• Boolean
• Number
• String
• Object
–Functions, arrays, regexps, errors, ...
• Invalid (no value)
20
21. QScriptValue type checks & conversion
• isXXX(): Tests if value is of a certain type
• toXXX(): Converts to Qt/C++ type
• qscriptvalue_cast(): Converts to C++ type
21
22. QScriptValue construction
• Constructors for standard Qt/C++ types
• qScriptValueFromValue()
• Counterpart to qscriptvalue_cast()
• QScriptEngine::newXXX()
• Object, QObject, Array, RegExp
22
25. QScriptValue holds reference to object (II)
QScriptValue same = object;
object.setProperty(“foo”, 456);
qDebug() << same.toString();
25
26. QScriptValue called as function
JS: myArray.sort(); or
myArray['sort'].call(myArray);
C++: myArray.property(“sort”)
.call(myArray);
26
27. Calling a function with arguments (I)
JS: myObject.myFunction(123, “foo”);
C++: myFunction.call(
myObject,
QScriptValueList()
<< 123 << “foo”);
27
28. Calling a function with arguments (II)
QScriptValue adder = engine.evaluate(
“(function(a, b) { return a+b; })”);
QScriptValue result = adder.call(
/*thisObject=*/QScriptValue(),
QScriptValueList() << 41 << 1);
28
29. Calling a function as constructor (I)
JS: function Point(x, y) {
this.x = x;
this.y = y;
}
...
new Point(10, 20);
29
30. Calling a function as constructor (II)
C++:
QScriptValue p = Point.construct(
QScriptValueList() << 10 << 20);
qDebug() << p.property(“x”).toNumber();
30
32. Working with JavaScript Arrays (I)
JS:
var a = [10, 20, 30];
print(a[0], a['0']); // same property
a.foo = 123;
a.push(40);
a[a.length] = 'appended';
32
33. Working with JavaScript Arrays (II)
C++:
QScriptValue a = engine.evaluate(
“[10, 20, 30]”); // array literal
qDebug() << a.property(“length”).toInt32();
qDebug() << a.property(“0”).toNumber();
// for convenience + speed
qDebug() << a.property(0).toNumber();
33
34. Error Handling (I)
// Uh-oh, this script will throw an error!
QScriptValue result = engine.evaluate(
“noSuchVariable”);
34
35. Error Handling (II)
if (result.isError()) {
QString message = result.toString();
// Notify user about the problem ...
}
35
36. QScriptValue API Summary
• isXXX(), toXXX()

• Initially contains properties defined by ECMA-262
38
39. Tailoring Scripting to Your Application
• Design “contract” of C++ <--> script interaction
• Set properties of Global Object
• Evaluate scripts that use your API
• (Optional: Call back into script objects as
appropriate)
39
40. Example: Meaning of Life Environment
C++:
QScriptEngine engine;
QScriptValue global = engine.globalObject();
global.setProperty(“meaningOfLife”, 42,
QScriptValue::ReadOnly);

52. The QtScript Debugger
• Graphical debugger
• Introduced in Qt 4.5
• To make the API available in your application:
QT += scripttools
#include <QtScriptTools>
52
54. The QtScript Debugger API (I)
One class in public API: QScriptEngineDebugger
QScriptEngine engine;
QScriptEngineDebugger debugger;
debugger.attachTo(&engine);
// evaluate scripts ...
54
55. The QtScript Debugger API (II)
• Debugger actions can be programmatically
triggered
• Individual debugger widgets are accessible
55
56. Invoking the Debugger from a Script
• Use the debugger keyword
• Becomes no-op if no debugger is attached
JS:
var a = Math.random();
debugger; // synchronously run debugger
var b = Math.random();
debugger;
return a + b;
56
57. Agenda
• What is application scripting?
• QtScript tour (the essentials)
• Debugger
• Misc.
57
60. Prototype-based Inheritance: Why care?
• Not every QObject member is a property / signal /
slot
• Not everything is a QObject
• Not everything should/needs to be a QObject
• JS developers are familiar with prototypes
60
61. Prototype-based Inheritance: How?
• Create a prototype object for the C++ type
• Register the type with Qt's meta-type system
• Associate prototype object with meta-type ID
• Create QScriptValues from the C++ type
(qScriptValueFromValue())
61
62. Bindings for Qt's APIs (I)
• Available as stand-alone project
• qtscriptgenerator on Qt Labs
(http://labs.qt.nokia.com)
62
63. Bindings for Qt's APIs (II)
• Creates plugins that can be imported into a script
engine
• Provides bindings for most of Qt's classes
• Makes it possible to write pure script applications
63
64. Summary
• It's easy to make your Qt application scriptable
with QtScript
• There's a QtScript debugger (also part of Qt)
• You can achieve a lot by mastering a small API
