QUESTION
Is it possible to convert a Qt/C++ code that uses threads executing an event loop and using the signal/slot mechanism with queued connections to communicate between 2 threads ?
I saw that there is this class called Dispatcher in C#/WPF (or WinForms), and I don't know if it exists apart from the UI context (can it be used in a .NET Console App or a Core App ?).
In Qt, I usually use this pattern : I have a class Application that holds the main window/widget and it launches a thread that handles non-UI stuff (acquisition from a DAQ card, communication with other devices etc...)
...ANSWER
Answered 2021-May-10 at 19:20By embedding JVM in your C++ application you can call any Java method in your secondary thread using Java reflection.
See: this link
But in general, low-level implementations (in C, C++, etc..) are called from higher levels, not in verse direction.

QUESTION
I have my own functions stored in the helpers.php file in the helpers folder relative to the composer.json file.
ANSWER
Answered 2021-May-02 at 04:57According to the Composer documentation:
Callbacks can only autoload classes from psr-0, psr-4 and classmap definitions. If a defined callback relies on functions defined outside of a class, the callback itself is responsible for loading the file containing these functions.
so any files normally included as part of a files autoloader type won't be included in this specific case.
As I see it, to get around this you have two options:
- Move the helper functions into a helper class as
staticmember functions and have that loaded via the Composer autoload mechanism (either psr-0 or psr-4) - Determine the location of the
helpers.phpfile andrequirethat in the migration file
For the first, it would look something like (in app/Helpers.php):
QUESTION
I have googled a bunch on how to fix this problem, but I'm kind of a beginner and none of the articles were related to python arcade, so I couldn't figure it out.
I'm trying to play background music in my game and I tried the python arcade Background Music example, but upon trying to get the position the example throws an error at me, saying: TypeError: get_stream_position() takes 1 positional argument but 2 were given. Has some update messed up some code or something?
...Heres the code I think is relevant to the problem:
ANSWER
Answered 2021-Apr-26 at 11:22Seems, that you're using old Arcade version. You have two options:
- update Arcade with
pip install arcade --upgrade - slightly modify your code by removing all arguments from
self.music.get_stream_position()
Here is the working example for old Arcade version:
QUESTION
I'm trying to make a simple Python Kivy app (using a kv file for the layout) that I will use to keep inventory of my parts for work. I am very new to python and kivy, so I need a little bit of direction on this.
One of the basic functions will be to allow the user to input a new part on the "Add Part to Inventory" screen (one of four screens). The user input consists of four items (part name, serial number, on-hand quantity, and the minimum amount needed).
Once the user enters this info and presses the 'Submit' button, I would like that data to be appended to a new row in a google sheet that I'm using as a backend database using the Google Drive/Sheets API (which I was able to get working).
Most of the example apps that I've found online only have one screen, and are only dealing with one type of user input (usually text, whereas my input will be text and integers).
I'm confused as to where I need to put my ids in the kv file (I'm assuming under the AddPartWindow layout), how to call a function when a button is pressed that is not in the root class, how to store the user input into a list since I'm not sure what the ObjectProperty function is really doing, and finally, how to append that list to a new row in my google sheet.
I'm not looking for a cut and paste answer, just some direction would be nice as I have not been able to find a good reference for exactly what I'm trying to do. My main confusion lies in having multiple screens, and how to transfer data between the different screens and their respective classes. Should data only be funneled through a single root class? Or can each class be used to handle data coming from their respective screens (windows) in the app? What exactly is the ObjectProperty function doing? I find the kivy website to be a bit convoluted when describing the properties class.
Any help/direction woud be greatly appreciated.
