8 – How can I limit the access to the scrolling text format in a paragraph?

I am trying to limit access to users to change the value of the drop down list in text format, but I can't seem to find the correct drop down list to change. Here is what I have so far, but it seems to disable access to the field itself and not the drop-down list in text format.

function hook_field_widget_WIDGET_TYPE_form_alter(&$element, &$form_state, $context) {
  if ($element('#paragraph_type') == 'my_paragraph_bundle') {
    $element('subform')('field_text_long')('widget')(0)('#format')('#access') = FALSE;
  }
}

scrolling – is there any research on where on the physical screen people prefer to read content

Andy, that would depend on the screen content and all the other user interface elements that grab attention, the page layout and the type of application that this page is about. is part.

But in general, people tend to read in the middle of their page rather than at the top or bottom and they tend to scroll blocks of 1 to 7 lines in very textual pages, like L & # 39; illustrates the study carried out by Microsoft: https: // www .microsoft.com / fr-fr / research / wp-content / uploads / 2016/07 / PETMEI2015scrolling_petmei_15_final.pdf

He does have a small sample, but it's hard to find reliable research on this subject.


If your question concerns less reading / scrolling behavior and more whether your users will notice / find your content. You can use tools like VisualEyes to generate a heat map based on the AI ​​of your design

reactjs – What can cause the unrendered image to flicker when scrolling in React?

Flickering only occurs once after each page loads. After that, I can scroll up or down without flickering.

Looking at the development tools, I see that the thumbnails are re-downloaded twice, which probably causes flickering, but if I add console.log("render") to the rendering method, I see that it is only called once.

What am I missing?

scrolling – Display a large graph inside a map in a dashboard

I'm going to design a dashboard, I know how to show the information but my client told me that a cohort chart would contain a lot of information. I'm wondering if it's okay to add an arrow to the chart that contains the graph to expand the graph on another page and add a link to it to return to the dashboard or what is the best way to do it (when we need to show more information for each card). Thank you!

scrolling – good place to add a recommendation section

We design an information section where the user can view all critical status products or campaigns.
we provide a "recommended section" at the bottom of the vertical scroll page.
I have a confusion that the user may not know if there is a useful section that will guide them to solve the problem caused.

Is there another solution for the placement of the "recommended" section.

My UX structure / hierarchy for this page is

Problem Statement> Details of Responsible Error> More in-depth details if any> Recommendation to resolve the problems.

ocaml – Scrolling of the text (marquee) in the terminal

I wrote an OCaml program that displays a scrolling marquee in the terminal:

Ocaml scrolling marquee

Coded:

(* Displays moving text in the terminal.
 * Uses VT100 escape sequences.
 * Usage:
 *     ocaml 
 * *)
#load "unix.cma"

let rec loop max_col curr_col =
    print_string "x1B(2J";  (* Clear screen. *)
    print_string ("x1B(1;" ^ (string_of_int curr_col) ^ "H");
    print_string "Hello world!";
    flush stdout;
    Unix.sleepf 0.2;
    if curr_col >= max_col then  (* Start from the beginning. *)
        loop max_col 0
    else
        loop max_col (curr_col + 1)

let () =
    (* Raise Sys.Break on Ctrl-C (SIGINT). *)
    Sys.catch_break true;
    print_string "x1B(?25l";  (* Hide cursor. *)
    try
        loop 20 0
    with
        Sys.Break -> print_string "x1B(?25h";  (* Show cursor. *)

The code seems to be working fine, as you can see in the GIF above. I need advice:

  • Did I write the program well? I am targeting terminal emulators that support VT100 escape sequences, and I want to make sure that this is portable on terminal emulators.
