            ambiguity of overloaded function taking constant Eigen argument
            Asked 2022-Mar-11 at 14:50

            I've designed a class with two overloaded functions taking Eigen data structures of different sizes.

            The code compiles as long as I'm passing lvalues but if I pass an rvalue I get a compiler error ambiguity because both return the same ConstantReturnType.

            Your example does not work because the return type of Zero() is not a matrix, but an Eigen expression.

            Thus, one way of achieving what you want with minimal changes is to use explicit matrix evaluation:

            How to better position Next/Back button in shiny glide, in order to eliminate large white space?
            Asked 2022-Jan-18 at 15:22

            The Shinyglide package is just what I need, using a carousel for grouped radio buttons giving the user many choices for data parsing.

            However, the "Next" (and "Back") button occupies a large white space. I'd like to shift the button in line with the glide row (see image at bottom). Does anyone know how to do this? Is there a CSS trick? Reading through the Glide manual, the only choices are "top" and "bottom".

            If moving the Next/Back button isn't possible, a secondary option is to insert (a somewhat superfluous) line of text but in line with the Next/Back buttons, to at least cover up the annoyingly large white space.

            The actual panel this is for has much more information presented than in this example, so I'm trying to make the page as clean as possible.

            Please see image at bottom that better explains what I'm trying to do.

            You could use a custom control element with custom_controls, and then have it hover over the displayed screen on the top right with a container set to absolute positioning. Setting a limited width for the container will ensure that the back button won't fly too far out.

            How to replace fluidRow with a horizontally scrollable non-wrapping row in tab panel?
            Asked 2022-Jan-17 at 16:07

            The reproducible code below uses a fluidRow() to house several user selections using radio buttons. Works fine in this limited example of only 2 radio button groupings. But I need to fit more radio button groupings into this row, without any wrapping. To do this, I'd like to replace this combination of fluidRow()/column() with a horizontally scrollable, non-wrapping row that is not subject to the limitations of the 12-wide grid system currently used in this code.

            Also, all objects viewed in the scrolling row need to be left aligned without "fluid" expansion. Currently, using this fluidRow()/column() combo, if the viewing pane is expanded, the 2 columns housing each radio button grouping also expanded which doesn't look good. They need to remain fixed width and stay to the left.

            Is this possible?

            I prefer sticking with this sidebar/main panel/tab panel/conditional panel layout as I find it very user friendly for navigating the type of data we work with.

            The image at the bottom further explains.

            How to place independent groups of radio buttons on same row and place well panels around the groups in order to delineate them?
            Asked 2022-Jan-15 at 18:36

            I'm trying to place 2 independent groupings of radio buttons on the same row, aligned, and separate those 2 groups with well panels (or boxes), for a start, in order to better delineate them for the user and make it clear that they are not linked.

            Below is a MWE of my attempt to place the radio button groups on the same row. I tried fluidRow() with columns inside, but no luck yet. The buttons don't work since this is stripped-down MWE. I left some skeletal things in like conditional panels, main panel, tab, etc., just in case those formats have an impact on what I'm attempting to do.

            The first image below shows what appears when running the MWE, and the second image shows what I'm trying to do.

            Please note that the real data table this is far extends 40 columns to the right, so I'm not worried about the fit of the radio buttons on one row (no need to wrap).

            The issue is that

            Column widths are based on the Bootstrap 12-wide grid system, so should add up to 12 within a fluidRow() container.

            See Application Layout Guide.

            As you have given each column the maximum width of 12 they will be placed in separate rows. To solve this issue reduce the column widths to 6.

            Javascript: Put time picker into input field

            I am tring to integrate a time picker into my webpage. I'm using Bulma Calender for this.

            However, results are only displayed and stored in the input field, when the "Validate" button in the time picker is pressed. For my purpose, I also want to put the selected information into the input field, when the "Validate" button is not pressed (e.g. just click anywhere else on the webpage after choosing a time).

            In bulma calendar there is a hide event, which I am able to trigger and to put the results into console: console.log(datepicker.data.value());

            However, I am not able to put the selected time into the input field.

            Interfaces can have multiple implementations. They just form the general contract implementations need to follow.

            The cache implementation here i.e. takes a DistanceFunction as input and guarantees that distance values between A and B (or B and A) are only calculated once and thereafter served from the internal cache map. The generic type of that cache function just guarantees that you can literally pass any type to it. I.e. you could have an implementation that takes in its simplest form just two integers and calculates the difference of these like this:
