            QtTest under PyQt5 fails when widgets-under-test have to be visible to work
            Asked 2021-Jun-15 at 17:01

            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:

            The 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:

            Combine values from duplicated rows into one based on condition (in R)
            Asked 2021-Jun-15 at 16:51

            I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name, the ministers position, the prestige of that position, and the year in which the minister had that given position.

            My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name and year). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.

            I want to create a dataset, where all the rows are unique combinations of name and year. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2 and prestige2. In the example with Bertel Haarder the data should look like this:

            (PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)

            As you manually use the loss and metrics function in the train_step (not in the .compile) for the training set, you should also do the same for the validation set or by defining the test_step in the custom model in order to get the loss score and metrics score. Add the following function to your custom model.

            Your immediate issue is that T: GarbageBin<'a, 'b> where 'a and 'b are parameters of create_bin_with_rubbish and must therefore outlive calls to that function—but the actual lifetimes passed to T::new are only internal to the function and do not therefore satisfy those bounds.

            Instead of parameterising create_bin_with_rubbish with lifetimes 'a and 'b, one way to resolve this would be to use instead an HRTB (higher-ranked trait bound):

            Three.js faces/vertices cut off but Bounding Box correct
            Asked 2021-Jun-15 at 12:48

            I'm using BufferGeometry to handle meshes with lots of vertices, faces and normals, which I supply via TypedArrays. During rendering, the Scene and its Mesh is constructed without any warnings or errors in the console. With BoxHelper I've constructed a Bounding Box around the mesh.

            Now the strangest thing happens: Although the Bounding Box is perfectly correct, the faces/vertices are cut off somewhere in the middle.

            To see what I mean, here is the comparison of two models rendered with a python script (left) and rendered with Three.js (right):

            How to convert a pair of iterator into a view?
            Asked 2021-Jun-15 at 11:41

            I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.

            Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.

            Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.

            EDIT:

            In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).

            In ranges-v3, there is iterator_range which you can use to wrap the iterators into a range object.

            In C++20, you can use std::span to wrap those iterators into an range object

            When you create new Navigation Drawer Activity, by default in the file named app_bar_main.xml Fab comes with it.

            Its implementation is in MainActivity file.

            you can change the implementation from here or can delete the code from these both files if FAB is not needed.

            This file lies on top of mainActivity that's why it is showing in each fragment.

            I see three challenges here:

            1. you need to extract a specific trait (CanWalk), regardless of its parameters, from a parameter pack
            2. you need to ignore extra copies of the same trait
            3. you need to set a default trait (CanNotWalk) if that trait is not present
