scroller | Accelerated panning and zooming for HTML and Canvas | Frontend Framework library

I have a Gtk.Treeview which shows rows with items. I want to select lines with button 1 (default behaviour), and, on clicking with button 3 (right), a context menu should appear. Here are the results I get:

1 - Using connect to connect to the button-press-event, works fine, but, as this handler is called before the default (treeview) handler, the line selection was not changed yet, and reading the selected row gives the previously selected line.

2 - Use connect-after to connect to the button-press-event. But now my handler is not called anymore... As if the internal handler exits with return True. Strangely, double-clicking does call to my handler.

How can I have button-3 change the selection first, then call my handler?

Here's a short version of the program, uncomment one of the marked lines to test 1 or 2.

BTW: I thought maybe set_activate_on_single_click might help - no luck.

The 2 buttons scroll the DIV left and right. However, I have such 5 such scrollers and the Javascript gets repetitive. How can we optimize this?

PS: Demo version shows only 2 scrollers.

HTML

I created 2 buttons that scroll the DIV left and right. However, it scrolls a fixed width. I want it to scroll each column of Bootstrap 5 on clicking Prev/Next.

or in simpler terms, I want it to scroll one column each to the left or right as per the click and not 100px each as it currently does. Please help.

I've made a Chat and the function that i'm trying to implement is that the chat should always scroll to the last message.

I have a weard problem with my (click) event, where second click is triggered in Angular code:

I'm learning Laravel framework and I wanted to add Select2 to my project with Laravel-mix. After many hours of trying to do that, I did it and everything seems to work fine, except one little, but very annoying issue.

When I click on my , the search input inside is not focused, so it looks like that: Okay, that not so bad, but when I click on the search input the black line flashes for less than 0,5sec: And after that this line looks like it should (pay attention that on the first image the line was missing): I'm not pretty sure, which lines of my code should I provide. I used npm i select2 command to install select2. Then I used composer require ttskch/select2-bootstrap4-theme command to install better look for bootstrap. webpack.mix.js mix.js('resources/js/app.js', 'public/js') .sass('resources/sass/datatables.scss', 'public/css') .sass('resources/sass/app.scss', 'public/css') .postCss('vendor/ttskch/select2-bootstrap4-theme/dist/select2-bootstrap4.min.css', 'public/css') .postCss('node_modules/select2/dist/css/select2.min.css', 'public/css') .sourceMaps(); bootstrap.js try { window.jQuery = window.$ = require('jquery'); window.Popper = require('popper.js').default; require('bootstrap'); require('select2'); require( 'jszip' ); require( 'pdfmake' ); require( 'datatables.net-bs4' )(); require( 'datatables.net-buttons-bs4' )(); require( 'datatables.net-buttons/js/buttons.html5.js' )(); require( 'datatables.net-buttons/js/buttons.print.js' )(); require( 'datatables.net-datetime' )(); require( 'datatables.net-fixedcolumns-bs4' )(); require( 'datatables.net-fixedheader-bs4' )(); require( 'datatables.net-keytable-bs4' )(); require( 'datatables.net-responsive-bs4' )(); require( 'datatables.net-rowgroup-bs4' )(); require( 'datatables.net-rowreorder-bs4' )(); require( 'datatables.net-scroller-bs4' )(); require( 'datatables.net-searchbuilder-bs4' )(); require( 'datatables.net-searchpanes-bs4' )(); require( 'datatables.net-select-bs4' )(); } catch (e) {} app.js jQuery(function () { $(".s2").select2({ theme: 'bootstrap4', focus: true }); }); app.blade.php ... Your choice Option 1 Option 2 ...

Please help me to understand my mistake and how to fix it. I have never used any framework before, so in my other projects I just added maybe about three lines of code and everything worked well, but here I feel totally lost.

I have been trying to create a program where QFrames are dynamically added to a QVboxLayout. As more and more frames are added to the layout, the frames not having enough space to occupy. I searched google for the problem, I found many stackoverflow answers, all of which use a QScrollArea. But when I added a QScrollArea with the QVBoxLayout in it, the scrollbars don't show up. Any help would be greatly appreciated. Here is the minimum reproducible example:

My code is working fine and displaying the tables with css well applied but when I am shrinking the window table is getting messed up with different columns taking up different space (I have attached in screenshot). Basically I want the first column which is without the checkbox to be intact(sticky) and rest columns to take equal space with a scroll enabled when I shrink the window . How do I fix that up, Can anyone please help?

Is there any way I keep the table container width as it is there in desktop view and just put a scroller in the mobile view with first column fixed and not shrink the tables?

like in this example https://codepen.io/paulobrien/pen/LBrMxa

I am creating a table in which I want users to have the ability to first filter the data with widgets to reduce the dataset, but still want users to be able to use the built-in DT filters to further reduce the data. However, when taking this approach I find that the built-in filters still contain values present in the original dataset which are not actually present in the data being passed along to be rendered.

For example in this case only 'setosa' and 'versicolor' are included in the table, but 'virginica' is still an option in the built-in filter.

Issue Example Image

Is there a way to make it so the built in filter only includes choices that are present in the input dataset?

Here is example code demonstrating the issue:
