I have two flatlists which are being created by this library. And I want to swapping of cells between the two sections. How can this be done? Or is there any other library which allows this?
I have also tried using https://github.com/gitim/react-native-sortable-list/
Or is there any other library which allows this?
I've used ReactDND with success before. You can certainly drag between sorted lists in ReactDND but it will take a bit of work. See here for examples:

I am in the process of learning ReactJS (NextJS) with Material UI. Currently i am trying to figure out, the best way to implement "interconnected lists". My idea is, to represent a hierarchy with n levels in n different lists side by side.
What would be the best approach for something like this? All i can think of is a huge mess off callbacks all over the place in one main file which coordinates everything, with one callback to the 1st list rendering the second list and the 2nd list rendering the 3rd list etc.
Note that i am new to JavaScript and to WebDev in general. I would only like to know, if that's the way to go or if there is an easier, simpler way.
I am trying to implement a way of displaying different components on a page at different weighted percentages (60% sees variant A and 40% sees variant B).
Is it feasible to do this on my own instead of getting a library? I was thinking of handling it inside of componentDidMount and simply creating that will see what variant they will see, then create a cookie based on that and drive the render of the variant they will see from the cookie.
Does that make sense from an implementation point of view?
This would surely make sense as it is feasible to do it on your own, but then the question is why would you not use a library? For example, the #marvelapp/react-ab-test already has very good work undertaken by others, which includes weighting variants that is apparently one of your main requirements.
Is it possible to refresh a single related list on a Standard Page Layout after a related list button is clicked (possibly using Ajax with OnClick JavaScript)? Has anyone attempted something like this?
I'm aware that this is possible using Visualforce, and I may need to go that route.
After digging around in the main.js JavaScript file included on all standard Salesforce pages, I found a way to get an array of all Related Lists on a Page. This is a "hack", and it is not guaranteed to work (and is certainly not supported, especially after each new release of Salesforce).
window.sfdcPage.relatedLists; // returns an array of related lists
There are available functions on each of the Related Lists returned. Each list can be refreshed by calling the makeRLAjaxRequest function.
// where 4 is the Related List number
window.sfdcPage.makeRLAjaxRequest(null,window.sfdcPage.relatedLists[4].listId);
I'm working on project where we are using jFreeChart. I need to use XYDifferenceRenderer and I need it to display difference graph of two functions. These functions don't need to be defined for all X-values. When these functions are not defined I would like to display nothing. So, the graph would look like there are gaps in it.
Does anyone know how to do something like this? I tried to pass null values to both functions, but it did not work. Do I need to extend XYDifferenceRenderer?
I have created an application that extracts the MSER data and stores it in a CvSeq*. I was wondering if there were any functions, or tutorials, in OpenCV that I could use to compare the data with another image using the extracted data of both images.
Thanks.
The simplest implementation of MSER happens to be this one using the C API. There's another listing from the Google SoC here using the C++ API.
I guess your best way to compare results would be to implement the code in any of the above links. Comparing the results with Matlab is generally a good thing, as we can expect that to be a standard (more or less). VlFeat has a library with both C and Matlab interfaces that has MSER functions. The last link also has a brief explanation from where you might be able to understand which "data" to compare. What sort of comparison do you have in mind - if it's similarity between regions in two different images, then using a Gray level Co-occurrence Matrix (GLCM) of the regions should work. The MSER will give you the regions, but comparison may not require further data of MSER.
Did you use the OpenCV cvMSER() function btw, or code the entire thing?
