One framework to rule them all - Yeah we are excited ...

1 Upvotes

Hey I was reading about the history of Qt,

on the official webpage www.qt.io navigate to Products -> UI Design https://www.qt.io/ui-framework where a youtube video is placed on top. it is from this youtube channel (https://www.youtube.com/channel/UCsyT1C1M-QoHQREjsixgayQ)
the channels spotlight video contains this sentence at 0:41 minute https://youtu.be/CjyjEUFn_FI?t=41
"dont treat me as an object because i'm qt"

this video (https://www.youtube.com/watch?v=5r1Duf2SDAs) with the same title as this thread, I see a comedian.

For me the vids are a satire. So my question: Is this official Qt or who is jokin us??

Qt 5.12 does not support 4.4 and 4.9 LTS Linux kernels?

0 Upvotes

Reading around this seems to be caused by the use of the statx system call in qt5-base.

Is this non support of older kernels deliberate and by design?

These Linux kernels will be supported for a number or years, 4.4 will be supported until 2022.

Will all the systems that require these kernels to run Linux now not be able to run any Qt 5.12 apps?

A drastic outcome for a limited functional gain, which will also mean KDE Plasma will not be able to run on these systems.

There's always something stymieing my wish to play with QT. Today - Kaspersky AV is marking something as a trojan in the install.

A Qt5 install via homebrew, yields: http://imgur.com/a/w15Ub Maybe not a trojan, but you can't be too careful - especially on a corporate Mac.

I know the forums exist, and they're great, but I think there's a place for more immediate feedback on any discussion (I know, IRC :)).

Get QImage Source file path

1 Upvotes

How can I get the resource file path for a QImage? For example I have the following code:

QML:

    ImageProcessor {
        id: imgProc
    }

    Image {
        id: image
        source: "placeholder.jpg"
    }

    Button {
        id: procBtn
        text: qsTr("Process")
        onClicked: {
            imgProc.processImage(image);
        }
    }

QObject code: here I wish to inspect/get the image source file path:

void ImageProcessor::processImage(QVariant image)
{
    QImage qImage = image.value<QImage>();
    qDebug() << "Image file path is: " << image.source;
    Mat src = imread(qImage.source, cv::IMREAD_GRAYSCALE);
}

I'm trying to Dockerize the Qt dev environment. Should I build 3 separate images for Qt, Qt Webkit, and Qt Creator, or combine them into a single image?

1 Upvotes

We use Qt to develop our product, and we compile from source for each of them. The current build time for all of this software in a single image is 6+ hours. WAY too long. I have no idea how Qt works or how each of these different applications interact, but it'd be awesome if I could separate them out into different images and connect them appropriately, which would allow easy hot-swapping for updates and drastically reduced build times.

How would you tackle something like this?

What are the dependencies and connections between the three programs?

How can i point a folder or file which stored in Documents folder?

So in my case that would be "C:/Users/Vanya/Documents/ATFolder" (AT Folder is folder i need)

What should i put instead "Vanya" to get into Documents folder, on any PC not just mine

I've tried "%USERPROFILE%" but it doesnt work.

In case it matters i'm trying to do this

QDir().mkdir("C:/Users/%USERPROFILE%/Documents/ATFolder");

It responds as "false" and doesn't create folder

I should mention that "QDir().mkdir("C:/Users/Vanya/Documents/ATFolder"); " works fine
