            error with vector, unique_ptr, and push_back
            Asked 2022-Apr-02 at 10:25

            I am learning smart pointers, with the following example test.cpp



            Answered 2022-Apr-02 at 09:43

            push_back expects an std::unique_ptr, when passing raw pointer like new Square, which is considered as copy-initialization, the raw pointer needs to be converted to std::unique_ptr implicitly. The implicit conversion fails because std::unique_ptr's conversion constructor from raw pointer is marked as explicit.

            emplace_back works because it forwards arguments to the constructor of std::unique_ptr and construct element in direct-initialization form, which considers explicit conversion constructors.

            The arguments args... are forwarded to the constructor as std::forward(args)....



            Rearranging polygons in geopandas for matplotlib plotting
            Asked 2022-Mar-08 at 20:20

            I am working on a project where I am using a shape file to make a choropleth map of the United States. To do this, I downloaded the standard shape file here from the US Census Bureau. After a little bit of cleaning up (there were some extraneous island territories which I removed by changing the plot's axis limits), I was able to get the contiguous states to fit neatly within the bounds of the matplotlib figure. For reference, please see Edit 4 below.

            Edit 1: I am using the [3.2 MB] shape file.

            The only problem now is that by setting axis limits I now am no longer able to view Alaska and Hawaii (as these are obviously cut out by restricting the axis limits). I would now like to add both of these polygons back in my map but now towards the lower part of the plot figure (the treatment that is given by most other maps of this type) despite its geographical inaccuracy.

            To put this more concretely, I am interested in selecting the polygon shapes representing Alaska and Hawaii and moving them to the lower left hand side of my figure. Is this something that would be possible?

            I can create a Boolean mask using:



            Answered 2021-Sep-22 at 17:25

            You could do something like this. You will have to find the right offsets to position Alaska where you want it to be exactly.

            Now, you have the following dataframe:



            Fastest way to clear group with a lot of shapes / multithreading
            Asked 2022-Feb-21 at 20:14

            In my JavaFX project I'm using a lot of shapes(for example 1 000 000) to represent geographic data (such as plot outlines, streets, etc.). They are stored in a group and sometimes I have to clear them (for example when I'm loading a new file with new geographic data). The problem: clearing / removing them takes a lot of time. So my idea was to remove the shapes in a separate thread which obviously doesn't work because of the JavaFX singlethread.

            Here is a simplified code of what I'm trying to do:




            Answered 2022-Feb-21 at 20:14

            The long execution time comes from the fact that each child of a Parent registers a listener with the disabled and treeVisible properties of that Parent. The way JavaFX is currently implemented, these listeners are stored in an array (i.e. a list structure). Adding the listeners is relatively low cost because the new listener is simply inserted at the end of the array, with an occasional resize of the array. However, when you remove a child from its Parent and the listeners are removed, the array needs to be linearly searched so that the correct listener is found and removed. This happens for each removed child individually.

            So, when you clear the children list of the Group you are triggering 1,000,000 linear searches for both properties, resulting in a total of 2,000,000 linear searches. And to make things worse, the listener to be removed is either--depending on the order the children are removed--always at the end of the array, in which case there's 2,000,000 worst case linear searches, or always at the start of the array, in which case there's 2,000,000 best case linear searches, but where each individual removal results in all remaining elements having to be shifted over by one.

            There are at least two solutions/workarounds:

            1. Don't display 1,000,000 nodes. If you can, try to only display nodes for the data that can actually be seen by the user. For example, the virtualized controls such as ListView and TableView only display about 1-20 cells at any given time.

            2. Don't clear the children of the Group. Instead, just replace the old Group with a new Group. If needed, you can prepare the new Group in a background thread.

              Doing it that way, it took 3.5 seconds on my computer to create another Group with 1,000,000 children and then replace the old Group with the new Group. However, there was still a bit of a lag spike due to all the new nodes that needed to be rendered at once.

              If you don't need to populate the new Group then you don't even need a thread. In that case, the swap took about 0.27 seconds on my computer.



            How to penetrate or cut holes through a 2D foreground
            Asked 2022-Jan-22 at 03:11

            I'm currently making a 2D game in Javascript, but I want to the game to have different lighting levels, for example, if I were to create a day and night cycle. However, I want to be able to cut holes in the lighting/foreground, or do something so that I can make certain parts of the screen lit up, for example like a flashlight or candle. Note: I'm also using the P5.js library.

            The most obvious idea that came to mind for going about in creating a foreground is just creating a rectangle with some opacity that covers the entire screen. This is good, but how am I supposed cut through this? Obviously, the code below won't work because I'm just layering on another element, and the rectangle is still obstructed and not perfectly clear.



            Answered 2022-Jan-22 at 03:11

            The erase() function may be what you are looking for. It is more flexible than trying to explicitly paint over the areas you want to cover (such as in the approach of using the stroke of a circle and rectangle to cover everything except a circle). And it is easier to use than beginContour() since you can use it with any of the built in drawing primitives (rect, ellipse, triangle, etc).

            I think it is very easy and simple question. but it is very difficult for me. please help! I can write R code



            Answered 2022-Jan-06 at 07:52

            Shortest way out would be to find what of b is not in a and then append it to a.



            Native Android -> How to create custom curved bottom navigation
            Asked 2021-Dec-17 at 09:03

            So this is the navigation my designer made for our project. Height of the bottom navigation is 70dp.

            What I have tried so far.

            First I downloaded a vector drawable background from design and set it as background for BottomNavigationView



            Answered 2021-Dec-17 at 09:03

            I think you cannot achieve this with BottomAppBar without working some hacks around it. I can suggest you use 2 FABs, an invisible one to get the BottomAppBar curved the way you wish, and another one (the actual one) and place it at the position you need it to be placed at, here is an example



            Jetpack Compose custom Badge with dynamic text size with CircleShape is not drawn correctly
            Asked 2021-Dec-09 at 04:01

            I had a BadgeView written with View using onMeasure, onLayout and OnDraw

            I'm trying to migrate this View to Jetpack Compose.

            Since drawing shapes is easier with compose i thought there is no need to use canvas or Layout functions at all, but size of Text or Surface wrapping it is not set properly before text size is calculated, and circle is not drawn properly.

            Also checked out Badge component, it uses static sizes BadgeWithContentRadius, since in my design size depends on text size it's not possible to set a static size.



            Answered 2021-Nov-16 at 14:11

            I would look into using the Material Badge that is already available for Compose:

            Jetpack Compose: Text remains black even when the theme is dark
            Asked 2021-Oct-29 at 10:52

            The text in the app still remains black even if the theme is set to dark and background is dark. Just take a look at the code and screenshots below.

            Theme.kt (here, in DarkColorPalette, I set onSurface and onBackground to Color.White but it doesn't help)



            Answered 2021-Aug-13 at 09:20

            You can specify Text color with using color or using style values.

            When there's no value specified for both of these, Text on compose uses LocalContentColor value, which is default to Black and doesn't depend on the theme

            If you wanna change default text color for the whole app, the best solution is to override this value right after introducing your theme:
