I can't add QtQuick.Controls component in Qt Design Studio. And I am facing problems while uploading the interface I created in QTDesignStudio to Apalis IMX8!

Hello Everyone!

We purchased Ixora V1.2A and ApalisIMX8QP 2GB V1.1C, products of Toradex. We downloaded the demo version of QT and wanted to create a simple interface to try it out.However, we cannot use some of the Components in QTDesignStudio.

I will share with you step by step what I did and what I could not do.

First I create a new project in Design Stuio (This is the 1st way).

This project I created has all the components and I don't get any errors when I add components.

But when I build and run, I get the following error.

09:29:00: Starting /usr/bin/appcontroller qmlscene -I /opt/UntitledProject17/imports -I /opt/UntitledProject17/asset_imports --apptype widget /opt/UntitledProject17/content/App.qml...

file:///opt/UntitledProject17/content/App.qml:30 module "QtQuick" version 6.2 is not installed

And the error displayed on the screen

2nd way;
I'm creating a new project again, this time I choose the MCU (since I can't see the MPU option)

and unfortunately I can't see all the components on the page that opens.

When I build and run, I can see this interface on my screen.

But when I add QtQuick.Controls to the interface

This yellow warning appears

And,
I get an error as follows.

09:51:59: Starting /usr/bin/appcontroller qmlscene -I /opt/UntitledProject18/imports -I /opt/UntitledProject18/asset_imports /opt/UntitledProject18/UntitledProject18.qml...

quit
Process exited with exit code 255
09:52:00: /usr/bin/appcontroller exited with code 0

Please help me with this problem. I want to load the interface that I created in QT to the MPU I bought, using all the components.

Thank you in advance for your feedback.

Hi,

Do you have a Qt build for your targets ?

[KeremADAY]

@SGaist said in I can't add QtQuick.Controls component in Qt Design Studio. And I am facing problems while uploading the interface I created in QTDesignStudio to Apalis IMX8!:

How I know if I have QT Build for the target devices?
And if I don't have it how to get it.

I am new to QTDesignStudio and Qt Creator. Sorry if I'm asking a simple question.

Unless you have followed Toradex documentation my guess is that you do not do.

I would recommend talking with them about that. They have a pretty extensive documentation like this getting started page.

Thus I would recommend to first get your environment up and running for development on your target and then come back to Qt Design Studio.
