When I call the method llaveCom.getName() I always get a null, I don't know why

What my code is about: I'm currently working on a project to create an image browser for all the images I have in my PC. I have created a database of all the images, this app will give me the ability to search through the database to find, and view and cycle through the images.

What my problem is: I'm trying to read left and right arrow key presses and connect them to a function that will change the shown image to the previous or next image in sequence. But for some reason the first two left-arrow presses don't register and none of the right-arrow presses register. Also, no other key presses are registering. My guess is that this is happening because the arrow keys are cycling through the widgets on screen. Need ideas on how I can fix this.

I am asked to remove a country (China) from the dropdown menu of the plugin intl-tel-input

the code below displays the dropdown menu and it looks that it calls the utils.js file to retain the countries

I've constructed a data.frame using the inefficient code below. Can you improve it, noting that if you can think of a better starting point, please include that answer.

My code takes data from the first two data frames and combines them to give the third. The first data.frame is a grid of 1s and -1s representing low or high values. The second data.frame includes all the information for me to calculate the high or low values. Note that each column has similar calculations but the calculation may differ from column to column.

Using Perl v5.28, Tkx.pm v1.10 with ActiveState Tcl/TTk v8.6.9 ('aqua' style), on macOS v10.13.6. The demo below works as desired, enabling the calling of a given subroutine using either a GUI button push using the mouse, or using keyboard input with a 'normal' text character.

The one additional feature I would like to have is the visual feedback of the graphical button being pressed (flashing) when the keyboard alternative activation is used. I found what looks like a Tcl solution using the event generate command, and a reference on using the Perl Tkx::event_generate() virtual event method call. I even found the equivalent Perl Tkx::after(100) function call to create the suggested delay. But I can't wrap my head around how to put this all together to achieve the desired effect. Any help would be appreciated, with the understanding that, like some other TTk features, this might not work on the Mac.

I wanted to center all my contents but I do not know how since I am not god in css. I tried to search online and found display: flex; justify-content: center; align-items: center;, but when I tried them it works fine but what I wanted was to center the form under the h1 and when I click calculate button the answer will go right below the calculate button. But things do not go right. When I click on calculate button, the answers show up on the right side of the form which is not what I wanted and also I wanted to center the form under the h1.

This is all my codes:

So I want to make a scraper for an idea I have to the following link: https://pageviews.toolforge.org/?project=en.wikipedia.org&platform=all-access&agent=user&redirects=0&range=latest-20&pages=Huilliche_people, but the infos I want from the site are dinamically loaded, so I am using WebDriverWait, but it gives me Timeout Exception even though the element is there and the class is not duplicated.

I'm new to web scraping and HTML. I intend to web scrape the first paragraph from a randomly generated Wikipedia article (which contains an introduction to the article). For this, I have written the following code
