C++ performance meets real UI.Shipped with Qt.
We don't build Qt demos — we ship Qt in production. Automotive dashboards, medical device interfaces, industrial HMIs, and desktop applications where C++ performance isn't optional. Qt development services for teams building software that runs on hardware — not just in a browser tab.

Why Entalogics for Qt
Four things every
Qt application
actually needs.
The Qt codebases we inherit usually have C++ doing everything including UI layout, QML treated as an afterthought, signal/slot connections that nobody can trace, and zero separation between business logic and presentation. Qt is powerful. Most teams use about 30% of it properly.
Performance01
C++ for the engine. QML for the pixels.
Heavy data processing, hardware communication, and real-time calculations stay in C++. Fluid animations, touch interactions, and screen layouts belong in QML. When teams mix these responsibilities, both performance and maintainability suffer.
Architecture02
Clean separation between backend models and QML views.
C++ exposes typed models and controllers via Q_PROPERTY and Q_INVOKABLE. QML binds declaratively. No business logic in QML JavaScript. No UI manipulation in C++. Two developers work on two layers without stepping on each other.
State03
Signals and slots with discipline, not spaghetti.
Qt's signal/slot mechanism is elegant until you have 400 connections nobody can trace. We enforce explicit connection types, avoid string-based connections, and document the signal graph so the next engineer doesn't spend a week reverse-engineering state flow.
Type safety04
Modern C++ and typed QML interfaces.
C++17/20 with RAII, smart pointers, and strong types. QML interfaces exposed through typed models — not raw QVariantMaps. When a property type changes, the compiler catches it in C++ and QML tooling flags it in the IDE.
When Qt, when not
Qt is a tool.
Not always the right one.
Qt is the most capable cross-platform native framework in existence. It's also C++ — and C++ demands discipline that most web-first teams don't have. We'll tell you on the first call if Qt is the right fit for your product and your team.
PICK QT WHEN
- Embedded hardware — automotive, medical, industrial — where the UI runs on custom hardware, not a browser
- Real-time data visualisation — sensor feeds, trading dashboards, SCADA panels — where 60fps on actual hardware matters
- Cross-platform native desktop — one C++ codebase for Windows, macOS, and Linux without shipping a browser engine
- Long-lived products with 10+ year lifespans — Qt's stability and LTS support are genuinely unmatched
CONSIDER ALTERNATIVES WHEN
- Your team writes TypeScript and the app is data-driven CRUD — Electron or Tauri ship faster with web skills
- Mobile-first product — Flutter or React Native have stronger mobile ecosystems
- Content-heavy web application — Qt isn't the right tool for what a browser does better
WE SAY NO WHEN
- "Qt for a web dashboard." That's a browser problem, not a Qt problem.
- "We want Qt because C++ is fast." Speed without architecture is just fast spaghetti.
- "Ship an HMI in three weeks with no hardware specs." That ship has sailed.

The playbook
Patterns we
ship on repeat.
Qt patterns from production embedded and desktop apps — not Qt Creator tutorials.
P01
QML for UI, C++ for everything else
Declarative QML for layout, animation, and interaction. C++ models and services exposed via Q_PROPERTY. The boundary is strict and testable on both sides.
P02
Typed model/view separation
QAbstractListModel subclasses with typed roles. No QVariantMap abuse. QML binds to strongly typed properties. When a role changes, the compiler catches it.
P03
CMake-first build system
Qt 6 requires CMake. We structure multi-target builds — desktop, embedded, test — with clean CMakeLists. No qmake legacy. CI builds for every platform in parallel.
P04
Qt Test + Squish for E2E
Unit tests with QTest on C++ logic. Squish or Appium for automated GUI testing on target hardware. CI runs on every PR.
P05
Boot-to-UI in under 2 seconds
On embedded targets: minimal init system, EGLFS renderer, precompiled QML cache, splash screen while services start. Users see UI before the kernel finishes booting everything.
P06
Incremental QML adoption
Existing Qt Widgets apps get QML screens one at a time via QQuickWidget. No full rewrite. The current app keeps shipping.
Signature case
An industrial control panel,
migrated from Qt 4 Widgets to Qt 6 QML.
A factory floor HMI on Qt 4.8 with Widgets — 12-second boot on the target hardware, a UI that couldn't be restyled without recompiling, no touch support, and a qmake build system that only one engineer understood. Migrated to Qt 6 with QML, EGLFS rendering, and CMake in 11 weeks. Boot-to-UI dropped to 1.8 seconds. Touch support added. Restyling now takes hours, not days.
Before
Qt 4.8 Widgets · 12s boot · no touch · qmake · restyle = recompile
After
Qt 6 QML · 1.8s boot · full touch · CMake · restyle = QML edit

Engagement shape
Eight to ten weeks
to a measurable ship.
A typical Qt development engagement. We build or migrate module by module — never flag-day. The current app stays deployed while we work.
- W01
Audit + RFC
Two senior Qt developers. Rendering performance profiling, signal/slot audit, build system review, target hardware validation. A ranked, dollarized RFC.
- W02–03
Foundation + first screen
Qt 6 baseline, QML architecture established, C++ models wired, one production screen on target hardware. Real frame times on the actual device.
- W04–08
Module by module
Screen by screen under feature flags. Nightly builds on target hardware. Your roadmap keeps moving.
- W09+
Deployment + handoff
Target image finalised. Qt Test coverage on critical paths. Build and deploy runbook handed to your team — or we stay on retainer.

FAQ
Sharp questions,
straight answers.
Widgets vs QML, Qt upgrades, embedded hardware, existing codebases — the questions we get on every Qt discovery call.QML for new projects — it's touch-friendly, animatable, and the direction Qt is investing in. Widgets for existing desktop applications where the codebase is already Widgets-based and a rewrite isn't justified. We migrate incrementally — QML screens inside Widgets apps via QQuickWidget.
Yes. Module by module, one deprecated API at a time. The app stays deployable throughout. A full Qt 4→6 migration typically takes 10–14 weeks depending on codebase size and deprecated API usage.
Almost certainly yes. Qt runs on Linux, RTOS, and bare metal. We need the target hardware specs — SoC, GPU, display resolution, input method — and we'll tell you on the first call what's required for Qt to render properly on it.
Yes. The engineers who write the RFC ship the code. No handoff mid-engagement. Direct access throughout.
Yes. We've worked inside qmake, CMake, Conan, and fully custom build systems. We adapt to your architecture. If something needs changing — like migrating qmake to CMake — we flag it in the RFC.
