ITEM COULD NOT BE CREATED

[mrjj]

@lalemola
Ok. that would be good. if it works in 5.15.xxx then we know the reason.
else im not sure what it could be as not seen that one before.

[tukangketik]

is there any solution for this issue ? even a clue where is the wrong part ?
I just installed qt 6.0.4 and XCode on macOS Big Sur and facing this issue.
i also installed latest qt 5.15 and no error on creating Window item.

[Tom4nt]

I am facing this issue as well, but in my case, it does not show "Go to error" in the designer, just a Window with 0 width and height, I suppose. Text editor works as expected.

Using Qt 6.1.2 and Qt Creator 5.0.0 on Windows 10.

@Tom4nt Have You found any solutions? Facing the same issue.

[KroMignon]

@nasir60 @nagaraj_4896 @lalemola @tukangketik @Tom4nt I never used Qt 6, but AFAIK in Qt 6 you do not have to specify the import version.

So if you QML looks like this:

import QtQuick 2.15
import QtQuick.Window 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}

Then remove the version information and I suppose it should than work as expected.

import QtQuick
import QtQuick.Window

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}

@KroMignon I am using Qt Creator 5.00! Still facing the same issue as @Tom4nt 4276713b-f528-438b-8987-7ddd07ebfe59-image.png

I am using Qt Creator 5.00!

Qt Creator is an IDE, it's version not relevant. What matter is the Qt Kit you are using.

[Zahid]

@KroMignon Qt version 6.12. How can I solve this? Should I downgrade my Qt version?

[Tom4nt]

@KroMignon Sorry for the late reply. I thought I would receive an email.
The project I created already came with the imports like this:

import QtQuick
import QtQuick.Window

I tried adding the versions though, but it didn't work.

I am facing the same issue on both my PC and Mac when using the QtCreator 5.0.0 and Qt 6.1 or 6.2 beta kits with new/old QtQuick Projects. The issue is not present when I'm working with Qt 5.15.2. Adding or removing version numbers does not have an effect on the issue. My PC is i9-10850K and GTX970 running Windows 10, and my Mac is Macbook Air M1 base model. Everything else works, including build, running on real devices / simulators, etc.

I tested Qt 6.1.3 GCC kit on Zorin OS (based on Ubuntu 20.04.3 LTS) and the problem is present there as well. Is there any solution to this problem or what could be causing it? There's no Felgo hot reload for Qt 6 yet to my understanding, so I cannot use that to bypass design view issues when developing front-end either...

I'm also experiencing this issue using QtCreator 5.0.0 and QT version 6.1.3 on macOS Big Sur (11.5.2). When starting a new project with the base qml window code, I can run the project and the window will appear. Switching to the Design view, I am unable to see the form in the form editor, and in the Navigator pane, hovering over the "Window" component displays the message: "item could not be created."

[c0ntrarian]

Popping in to say that I am experiencing this issue when I create a new project in QT Creator with the Qt 6.0 minimal version selection.

[sbentzien]

Having the same issue with Qt Creator 5.0.1, Qt 6.1.3 MinGW 64-bit on Windows 10 64bit.
All items in the Navigator panel have a warning sign next to them, are underlined in red and their tooltip says 'Item could not be created'.
Running the application works like a charm, but the preview in the Form Editor doesn't work.

[lucas.gmiranda]

@sbentzien same configuration and the same issue here

[John Cordell]

Is anyone aware of how to escalate this with the QTCreator Dev/Support team? This seems like a painfully long time to have an issue like this, which is a software block, and not have been follow-up on by someone.

[jsulm]

@John-Cordell Was this reported as bug in Qt bug tracker?

[The-EDev]

I'm facing the same issue, happens on QTCreator 4 and 5, only happens when using QT 6.1.3, QT 5.15.2 works just fine. Removing version number from imports did not help.

[Martin-Barrett]

Me too, 5.15 fine, 6.1.3 gets red squiggles under "window" in design view.

[Nathan Miguel]

This work for me! QT 6.2.0

1. Go to Tools > Options > QT Quick

2. Inside QT QUICK DESIGNER TAB check the second options and copy/paste same path of first in secont

3. Restart your QT and wait for build

OBS: Autocomplete dont work when import something like quick controls, so import without version or put 6.0

Enjoy!
