Qt for Python (PySide/Shiboken)

Hi, all! I'm trying to create and use a custom Qml module. The docs are confusing as regard to: - create the import Paths. - create the module structure (i.e: paths, qmldir file) - how to import them. I either get to results: module "Example" is not installed or (if I use paths) that a property (that exists and is set) is undefined. If anyone has any step-to-step, I'd appreciate. To import/install module I tried adding a env. variable with the path to the module and adding it to the project.pro file. Neither seems to do any difference.

Thank you! I will have a look on it tomorrow. Seems quite easy with your approach.

👌

You are trying accessing the from which qml file?

main.qml.

I'm not sing the main.qml in your screenshot

it is in the root dir.

And the file, you are trying to access is the qml file under commons is that right ?

yep!

let me test it

I could not help if I can read the error line

Character.qml import QtQuick 2.12 Item { id: nada property var character_: { "id": 174 } property int last_stat_value: 0 property string last_stat: "" property var character_info: { "id": 174, "creation_type": "fast", "points_total": [6, 7, 4, 10, 10, 6, 8, 5, 6] } } (removed other values for brevity)

could you show it

That's how I reached to this point: trying to see how to declare a global variable the best way possible.

I usually declare a property in the top level (main.qml) so that i can reach it in any file, At each inheritance level I declare a variable which will transfer the variable from the parent to the next child, and so on.

Ideally, I'd create a singleton (or something like that) instead of global variables. Then, I can work on in a more flexible manner.

The second one method, it is to have a global variable inside a unique qml file like ValueSource.qml, so that i could import it in any other file like we did and respecting the import rule.

But that will suffice for now!

Yeah, these global value stuck me many time, something as for a long week to solve the issue

You're aware of registerSingletonType ? (I don't recall the exact name, but it's a call you can make on the engine to register a type - I think it's available in the python API). This will register a singleton object that the engine will instantiate.

yeah, I assume it. This could work too.

So, I hadn't been doing much Qt for Python/PySide stuff, instead working with customers that have Qt C++ projects, but a few days back I started a hobby project to help my girlfriend. She wanted an automated way to count pills, and was asking if a particular app on the Amazon app store was ok, as it seemed sketchy to her. I agreed - it was asking for all sorts of permissions it shouldn't need like location permission. Anyway, she was wondering if I could make such an app. I could make something for Android, but it would take me some time, and I thought the project would be a good way to get some experience with using PySide6 with QML and opencv.

hey guys , maybe somebody can you tell me what its the wrong of my code , please :c this is the qml CustomButton { id: button x: 75 width: 150 height: 35 text: "CALCULAR" anchors.top: parent.top font.pointSize: 15 anchors.topMargin: 15 anchors.horizontalCenter: parent.horizontalCenter onClicked: { backend.multi(number1.text , number2.text) } } Connections{ target: backend function onSetMulti(result){ multiResult.text = result } and this is the python code setMulti = Signal(str) @Slot(str) #funciones def multi(self,n1,n2): result = float(n1)*float(n2) self.setMulti.emit(result)

PySide6 can run on android? If so, it is waouh.

this is the error : TypeError: numero1() missing 1 required positional argument: 'n2'

i'm supposedly sending all the arguments but i don't know why the error

sorry :'c , in this case this is my python code and..: https://pastebin.com/AhCLrP6Y this is my qml code : https://pastebin.com/HBfJ6cX6

thank you so much , I've been trying to do the backend and I got caught up in this :c

No worries!
