Qt Design Studio for python

[Guilherme Franklin]

I'm having trouble creating a designer in Qt Design Studio and exporting it as python code.

If anyone can help me with this, or know of a course that teaches python programming using Qt Design Studio, I would be very grateful.

Hi. Are you sure you mean Qt Design Studio, not Designer? Design Studio is for designing the look of a UI, not for writing code.

Yes. I'm new to Qt and don't know much about the features.

I managed to understand that Qt Design Studio is for creating the user interface, but I am not able to import it into a python code to be able to implement the features of my program.

For example.

I have the following python code:

# This Python file uses the following encoding: utf-8
import sys
from pathlib import Path

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine


if __name__ == "__main__":
     app = QGuiApplication(sys.argv)
     engine = QQmlApplicationEngine()
     qml_file = Path(__file__).resolve().parent / "main.qml"
     engine.load(qml_file)
     if not engine.rootObjects():
         sys.exit(-1)
     sys.exit(app.exec())

It imports a .qml file:

import QtQuick
import QtQuick.Window

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

This way works correctly, however, when I create a new project in Qt Design Studio, I have the following problem:

In this structure I include a python file with the same previous code inside the content folder and import the App.qml file

# This Python file uses the following encoding: utf-8
import sys
from pathlib import Path

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine


if __name__ == "__main__":
     app = QGuiApplication(sys.argv)
     engine = QQmlApplicationEngine()
     qml_file = Path(__file__).resolve().parent / "App.qml"
     engine.load(qml_file)
     if not engine.rootObjects():
         sys.exit(-1)
     sys.exit(app.exec())

But when I run the python code I get the following error:

QQmlApplicationEngine failed to load component
file:///C:/Users/guirn/Documents/UntitledProject/content/App.qml:5:1: module "UntitledProject" is not installed

I want to be able to solve this problem so I can run my interface created in Qt Design Studio with Python.

@Guilherme-Franklin I would strongly discourage you from using Python when your application is "GUI oriented". From my recent experience - Python is "(simple / single) command line scripting language" and adding GUI to it is not a simple task. You can use QDesigner to build the GUI ( ui file ) then you need "uic" ( user interface compiler) to "convert" .ui to . py and that is where the tools do not work well together.
But that is my (fact based) opinion, your mileage will vary...

I understand your position, however, this problem I'm having is recurrent even in other languages.

For example, I created a mobile project in Qt Design Studio with the following structure:

Then I opened it in Qt Creator to be able to compile it into an android apk and I'm having the following problem:

That is, even if I follow your advice of not using python, I will still have the same problem. I would like to ask for your help in resolving the issue.
