QUESTION
I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).
Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?
I thought that I could do this with generic type arguments:
...ANSWER
Answered 2021-Jun-15 at 23:55I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.
Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:

QUESTION
My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:
...ANSWER
Answered 2021-Jun-13 at 20:18The problem is that you are using an empty notesListAll list for filtering results; you need to populate it with the list of notes in the constructor

QUESTION
I'm following a tutorial about RecyclerView, but I can't write ct: the way he did. I typed in manually, but it does not work. I'm not sure how he typed it. He typed in this, then android studio writes ct: automatically. What do I need to type to do that?
MyAdapter is a class I created for RecyclerView. Here is the code for that class:
...ANSWER
Answered 2021-Jun-15 at 19:45The little lighter colored "ct" prompt is just a visual aid and it does not always show up. When you provide a raw value as an argument, it will show the prompt (like this, 1, or "foo"). When you provide a variable for the argument like ctx, foo, etc, it does not show up. This goes for all functions that take arguments.
The moral of the story is, it is not important and can be ignored.
QUESTION
I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.
I can figure out how to change one area, but unsure how to implement the other areas.
What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.
What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?
...ANSWER
Answered 2021-Jun-15 at 11:48You could try having a "select" function run when you click on one of the areas. This function would "highlight" the area (border-color), and save the id of the area in a variable.
Then when you click on the color swatches another function would run that will take the value previously saved id and select the HTML element based on that.
QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".
Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:
ANSWER
Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:
