I'm back with a GPU.. Qt Creator still not working
-
@JonB Yes, now there is no more error and it builds but the design page doesn't activate at all, even if I open the qml file.
-
@Ronel_qtmaster But I think you need the plugin for it to interface with design studio. And anyway I was told that it is different than design studio. Regardless, on updated windows 10 I can only get to the page if I install the plugin and it still doesn't work.

Like I said, I have never used or installed QML. But if you keep your Ubuntu in this state I will just install thatqtdeclarative5-devtomorrow and see where I find myself :)wrote on 22 Mar 2024, 18:52 last edited by Mlibu@JonB So a question... I found this posted on the qt creator 6 release:
https://www.qt.io/blog/qt-creator-6-released
"The integrated Qt Quick Designer is now disabled by default. Qt Creator will open .ui.qml files in Qt Design Studio. This is a step towards a more integrated workflow between Qt Design Studio and Qt Creator (video). Qt Quick Designer is still there, you can manually enable it again by checking the QmlDesigner plugin in Help > About Plugins."
Yet when I try to activate the plugin, there isn't one to activate.
So if this was underway in qt creator 6, is it going to do anything different than qt design studio does anyway? Is this even supposed to work in qt creator 12?
I watched some videos on qt design studio and they seemed to be more geared towards creating components than creating a full application. Also a lot of the functionality to migrate from photoshop is commercial and that won't be avilable.

@Mlibu When did you install it?
sudo apt install qttools5-dev-toolsnow you can write down all libs and packages you need into a shell script.

@Mlibu Actually, Qt 6 is old in Ubuntu 22.04. You can install Qt 6.6.2 with Qt online installer. I purged Qt6 in Ubuntu 22.04 and installed Qt 6.6.2.
wrote on 22 Mar 2024, 21:50 last edited by Mlibu@JoeCFD I think I found a couple other threads with the problem I am having.
https://forum.qt.io/topic/152332/item-could-not-be-created-please-help-me
I don't think it's to do with the install at all really. Rather, Qt is failing to interpret the small sample file and the rendering is messed up because it is confused about how large the window is. The error "item could not be created" on the window is the key I think.
Anyone who solved it seemed to switch from "Use fallback emulation layer" to "Use QML emulation layer that is built with the selected Qt" in Edit->Preferences->Qt Quick->Qt Quick Designer. I just don't quite know how it works or what to set it to yet.
Some people have run qmlpuppet on its own and seen if it has errors. Will try tomorrow.

So I just found this bug report, last reported in February!https://bugreports.qt.io/browse/QTCREATORBUG-30202
Qt recommends to use Qt Design Studio! But it's not the same?? To my knowledge Design Studio doesn't even support adding signals and slots.
UPDATE: This is so very confusing... I found this page:
https://cutehmi.kde.org/docs/3/doc/md_using-qt-creator-in-design-mode.html
He says you need to build in release for the Designer to work so I did a release build but that didn't work for me. Then he says you need to set the QML emulation layer, which I was kind of on to.... but set it to what?? he doesn't say!

wrote on 23 Mar 2024, 11:49 last edited by Mlibu@Mlibu Ok well I thought I had figured it out with this forum comment:
https://forum.qt.io/topic/148745/cannot-connect-to-qml-emulation-layer-qml-puppet
So I thought I needed to change the 'qml emulation layer' to the directory that holds qml2puppet which I found under QtQuickDesigner directory. But that didn't work either.
I also tried the puppet in /usr/share/qtcreator/qml/qmlpuppet/qml2puppet and that didn't work either.
I think I need to resign myself to the fact that there is no possible combination under which this will work for me. I have exhausted every measure I can find. I will either do QML by hand or use Design Studio.
It's a funny thing this problem. There are a few comments out there that Qt Creator is a piece of sh%t and they can't get it to work and they are just going to use something other than Qt and they basically have the same problems I have. Then there is a youtube video of someone having it work fine from 2023. I don't know how this all adds up, but this is taking time from other important work that I have.
I did ./QtDesignStudio/qt6_design_studio_reduced_version/bin/qml2puppet-4.4.0 --test
It looks fine. All libraries there and loaded.
After this I also tried to remove build directories and start a new project but it still doesn't work. There are just so many conflicting comments and instructions I don't know what to do any more.
Please, please.. if anyone can figure out what my problem may be, I would love to hear the answer. But I have had to put way too much time into this.
I'm going to tuck my tail between my legs and go back to Manjaro KDE now. I'll leave a small partition to test other OSes with if anyone has any other ideas.

Create a qt quick project in qtcreator. Open it in qt design studio for visual editing and qml coding. Learn what makes sense to do with qml and javascript and when to use c++. It is designed to work together.
It's all in the documentation.

If you only design UIs and don't neeIf you only design UIs and don't need the developer tools, you can install the stand-alone Qt Design Studio package. It contains all the Qt modules and tools you need to design UIs and preview them on the desktop. The Qt Quick code is automatically generated for you, and you can deliver it to developers for implementing the application.

Also if there is a place in the documentation where they explain how to work with qml exported from design stidio? I see the robot arm tutorial and it says how to export but not how to interact with the code from c++. I know how to export c++ objects to the qml engine but i have never seen an end to end example of the whole thing. Whereas there are examples of how to do it with qt Creator.
