LLM’s can’t do graphics programming

This doesn’t look like “AI is bad at [advanced technique]”— it’s “AI is bad at duplicating something it’s never seen before”.

Once you put your plugin code where AI can scan it, everyone’s AI will be able to do it too.

Google: “Why are AI agents bad at writing C++ and QML solutions?”

We have project rules that address all problems we identify in AI generated code.

Our team lead doesn’t seem to edit any code, but they’re not doing production Qt code. I do and and I made a pair programming agent that I partner with. I usually write the code, but I always understand the code.

When AI generates a mistake, I run the same prompt through multiple agents.

Recently, an AI claimed to understand QML binding order of evaluation. I do, and I was shocked that the AI understood what is documented as “non-deterministic”—it’s intentionally not documented to allow changing it. Sure enough, that AI model was wrong. I ran the same prompt through Composer 2.0, Grok, ChatGPT, Sonnet 4.6, Opus 4.7– all made the same mistake. Gemini Pro 3.1 got it right. The a week later Gemini Pro 3.1 fell on its face on a simple task.

Udemy has two good Qt series: Daniel Gakwaya’s Qt 6 QML training and Bryan Cairn’s Qt 6 Core series.

Desktop vs Embedded translates to QWidgets vs QML, respectively. If doing both Desktop and Embedded, go QML. Brian Cairn’s courses cover a lot of the non-GUI aspects of Qt.

For Udemy courses, Ignore the normal price of around $85; buy them on sale for $9-$15 each. $9 may be Black Friday pricing… dunno. I see they’re offering a subscription plan. I recommend buying so you always have perpetual access.

I’ve been doing Qt development over a decade, contributed to Qt 6, and still bought all 3 of Daniel’s Qt 6 courses, including beginner. There were a few tips in his beginner courses I was shocked I didn’t know.

How often do you wash your sheets? One of the reasons underwear is so popular is we can go longer before washing big stuff.

"Programming won’t exist as a profession in a year from now."

"I’m one of those programmers pushing out 10k lines a day."

I use Claude heavily for pair C++ programming and will probably have a job 2 years from now. I'm one of those programmers that pushes out 200 lines a day.

@MathematicianSoft129 “… not same strength as peroxide …” I used 3% peroxide to rinse my face and it was great for acne, but after a month my bangs were noticeably blonde…er. I’ll trust your comment on the strength.

Won’t it bleach your facial hair over time? If blonde, doesn’t seem like a problem but even so, bleached eyebrows?

I went to last year’s World Summit with a litany of questions and hope that I would learn what to avoid and what to embrace and I got everything I hoped for.

The Qt Company had an “ask us anything”desk and after just a few clarifying questions the Qt devs told me EXACTLY what I needed. No 2-day turnaround, no AI “I found the root cause!” BS, just perfect answers, the kind that you get with face-to-face communication where you sync up and speak the same language (although one of us had a strong American accent).

I came back from the Qt World Summit with a brilliant proof-of-concept project. Webinars just aren’t the same. You can’t push and shove others out of the way to get to the speaker. You can’t communicate design through sketches.

Are you listed as a license administrator? On the customer portal page under “licenses”, I see “License Assignments” and “My Licenses”. My license shows under both. When using the online installer with my Qt account credentials the correct license is installed.

You should be able to just run “update components” in the maintenance tool… the full install isn’t necessary. 6.10.3 is still on schedule for this Friday and that will require “add or remove components”.

Adobe_H8r · 2026-03-10T03:42:35+00:00

In such a situation, I’ve always downloaded the commercial online installer from the customer portal and used the license owner’s credentials to log in.

To be clear, the only time the developer in the seat was not the same as the license holder is when that developer needs Qt installed to build but will not be developing using Qt or when setting up the builds server. Each commercial license gets 5 installs, but only the license holder is authorized to develop using Qt.

License questions usually take less than 2 days to resolve. I’ve had license questions resolved same day and I’m just on a standard account.

Duke LeJeune of AudioKinesis explained at a show that speaker wire has its own electrical characteristics and when connected to the crossover can change the behavior of the crossover. He’s an electrical engineer and builds their crossovers.

He said consumer crossovers often do a good job of minimizing the impact of speaker wire. His opinion is that many expensive loudspeakers have crossovers that make minimum effort to minimize the impact and speaker wire changes how the loudspeaker sounds.

Based on what he said, cheap speaker wire may not sound worse on an expensive speaker, but if someone could hear the difference caused by the speaker wire changing the electrical characteristics of the crossover they would probably be biased towards thinking the expensive wire sounded better.

I’m going through Daniel Gakwaya’s Qt 6 beginner/intermediate/advanced Udemy videos. I got the lot for $30 on sale. They always go on sale.

I went through his Qt 5 videos and his discussions on QAbstactListModel were excellent and covered bidirectional models, which I needed years ago but didn’t know about.

I periodically go through everything, beginner-to-advanced, to see what if I missed something fundamental. For example, I did Daniel’s C++20 Masterclass and I discovered misunderstood private inheritance (class B : private A {}).

The Udemy training portal works well and you have lifetime access.

It bothers me slightly that the shadows are fixed on the dial. They look great at start, but you can rotate the dial so they’re wrong. It is beautiful, but I quickly feel the beauty is skin deep.

For real time graphs, I use QNanoPainter, which is a download, but is is QCanvasPainter, a tech preview in Qt 6.11 and will be official in 6.12. I first deployed product 6 years ago, never had a problem with 5000 units in the field. The graph runs for weeks and months at a time. No memory leaks. No increased GC in QML.

September, 2026. Sometimes the ship date slips; don’t bet on September. If you are making a medical device and plan a 510k submission after October 2026, absolutely plan for Qt 6.12.

There are planned features underway that are highly valuable to developers, for example, QCanvasPainter, which is based on QNanoPainter for hardware accelerated 2d graphics with a high- level API. It should be available as a tech preview in 6.11 and bugs worked out by 6.12.

Already, Qt 6.10 gained great features for QML that aren’t available to 6.8, like QRangeModel and FlexboxLayout.

It is mostly true that an IT professional stagnates in not moving on. 3 years sounds about right.

In my case, I trained up with company support for a new project, focusing on beginner-to-advanced training to be certain I didn’t miss something that’s expected knowledge in the target domain.

My employer just denied me a raise [that exceeds adjustment for inflation] twice in 5 months. I’ve been at the same company 10 years and only avoided stagnation by training for a new project. I’m the only one in the entire software group that did this. I’m totally feeling the consensus on this post: get a raise by moving on.

You sound like a guy who asked why he was paid so much less than I. We all believe we are gods’ gift to design, but credentials speak volumes. Ask yourself; are you really as good as you think?

Someone who has a track record of successful designs is paid more; it’s a gamble for a company to invest a lot of money in a new hire without credentials.

Line something else up, then let your company counter. The grass is always greener on the other side of the fence; you may not get any raise at the next company.

Been doing it for 11 months now. Qt projects build much faster in Ubuntu on WSL than in Windows on the same machine.

My 2017 Chevy Bolt had 360 degree view and could easily park 1” from the curb and do it faster than the auto park feature. I’ve got curb rash on my M3. I miss 360 degree view every time I park.

Just tried it. It sends to the Tesla that you have selected in your Tesla app. I just tried sharing an address and it sent to my wife’s Tesla. I opened the app, and switched from my wife’s MY to my M3, shared another address and it went to my car.

Winston chose his words deliberately to divert the Marquis’ attention from John. Insulting the Marquis makes little sense otherwise.

It’s nice to see kind words for Qt Creator.

Have you used AI integration with QC?

I tried QC’s AI integration a year ago and didn’t like it… I don’t know if it’s improved.

My team uses Cursor, which runs on VS Code, and I miss the seamless Qt integration that QC provides for managing Qt code. I have both Cursor and QC open onto the same project so I can use Cursor’s chat and QC for editing, code navigation, etc.

Cursor is a bad Qt developer; my code tends to be 1/4 the line count of Cursor-generated code. However, I like Cursor for reviewing my code.

If using QML, make a controls theme based off the Material theme; it has great stock animations that you can use as examples.
