QML and Qt Quick

Fixed in 6.8.2

I wonder if that forum post is referring to text components that support html to some extent, rather than to QML itself?

Though that page doesn't show any QML examples as far as I can see. I recall having to try a few things when I first wanted to do this a few years ago. I don't know if what I arrived at is the "correct" approach, but the format that I found to work in QML and have stuck to ever since involves using a triple forward slash like this: source: "qrc:///images/my-image.png"

@Praveen-Illa said in Facing an issue with Listview in Repeater: Hi Team, I am trying to control the visibility of the listview control on every button click for respective data model. But, I am getting below errors at "visible: buttonRepeater.model.expanded" Unable to assign [undefined] to bool Edited to emphasize the problem: Repeater { id: buttonRepeater model: groupModel delegate: Column { ListView { visible: buttonRepeater.model.expanded } } } buttonRepeater.model.expanded is attempting to access a property called expanded in buttonRepeater's model, not a role called expanded within a row of the model. Printing the values of buttonRepeater and buttonRepeater.model should make this clear.

Looks like it's QTBUG-133587. I also have .js files in QML_FILES.

@jeremy_k Thank you for your input. It seems I have to rethink the concept.

Hi, Are you looking for something like the Vulkan under QML example ?

You go the answer on this thread, correct ?

Okay so it seems that the problem is the compiler not being the same in Qt Creator than in Qt Design Studio. My Qt Creator kit on Windows is using MinGW but it's not compatible with whatever Qt Design Studio is using. Does someone know how to proceed?

@RokeJulianLockhart, per bugzilla.redhat.com/show_bug.cgi?id=2345428#c1: The real binary is installed into /usr/lib64/qt6/bin/qml, and symlinked to /usr/bin as qml-qt6 to not conflict with the Qt5 version.

@UnknownCollegeCoder said in Enabling arrow-key-navigation with QtVirtualKeyboard on Qt 5.15.1: Would you happen to know how I get this configuration to my current project? You don't! Again: this instruction is to BUILD Qt virtualkeyboard itself, not your project! After calling configure you call make and then "make install" (just like @Joseph-Keene shown already).

@RokeJulianLockhart don't be so harsh to your younger self. People make mistakes. You have to learn from them and grow past them :-)

QtQuick used to require a GPU to be present. But now a software renderer which has limitations. @SGaist, thanks for that. Never would have found that article in a million years. However, I found a comment which appears to summarise both its current state and why I asked this succinctly, if correct: Yes QtQuick is much much faster in rendering high resolution complex scenes due to leveraging the gpu through the use of QRHI. Its the awesome rendering abstraction Qt made so it will call Dx11 Dx12 Vulkan Metal Opengl depending on the platform you compile for. This ensures you use the best graphics api for the platform as Opengl drivers (from most gpu vendors)on windows sucks compared to DirectX, so much so google even developed ANGLE. But I hear you say the word ‘responsiveness’ and this is something were a very nasty truth comes to light about QtQuick. By default Qt uses VSync and a swapChain interval of 2 or 3 frames (you can configure this) to throttle the rendering so we are not rendering 7000fps for a screen that can only display 120 per second. This adds latency which is noticable to the user. Likewise, since I'm asking this in a KDE context, reddit.com/r/kde/comments/81dfdc/comment/dv37xdr is of use: Today we need to compare QWidget and QtQuick. QWidget is rendered with what raster used to be, so no. QtQuick is by default rendered with OpenGL, so yes. Though, I presume they mean QtWidgets in the stead of QWidget.
