QUESTION
We're in the process of upgrading our web application from ExtJS 6.0.2 Classic to 7.1.0. We would also like to switch over to the Modern framework in the process. However, there is some code that is using the BoxReorderer class, which is not available in the Modern framework. It is being used as a plugin on a grid to allow the columns to be reordered. Is there an equivalent class or way to allow the user to reorder the columns by dragging the header sections in the Modern framework, and if so, what is it?

QUESTION
I have a grid column containing combobox as its editor and am using celleditor
plugin in which I want to write some validation logic. When I try to select something from the combobox cell, it is expected to lose its focus after the value is changed and then it should go to the validateedit
listener. I know there is a blur()
method on combobox which will resolve this issue. But as per document, it is a private method so am avoiding that. I wanted to know if there is another way to lose the focus on change or picker collapse or any config which will perform validation on change of field.
Below is the code and fiddle.

I using extjs version 7.4.
The icon is clearly visible in the example of Sencha. https://examples.sencha.com/extjs/7.4.0/examples/kitchensink/#menu-buttons
However, icon isn't displayed in my actual code screenshot
Is there a problem with my source? Or is it a Sencha bug?

...ANSWER
Answered 2021-Jun-02 at 18:39I guess you missed to define the classes like here:
As an alternative you can try to set the icon like that:
- iconCls:'x-fa fa-home'
Which prefix you will need depends on your FontAwesome version.
Following this approach you might need additional classes to scale the icon. But i am not sure.
QUESTION
How to customize CSS in order to force dataview (Ext.view.View - classic toolkit) item to be equaly distributed in vertical direction. I have dataview that I would like to present in two columns, but items are not of the same height. I would like to distribute them evenly in vertical direction. Since a picture is worth a thousand words, here is the picture of what i get and what I would like to achieve:
So, dataview aligns items vertically, but I would like that item 3 starts just below the item 1. Basically, I would like that items are poopulated orderly one below the other. I would also like to avoid having two dataviews (one for the left part and the other for right part).
Here is what I got so far:

QUESTION
Any one has a idea on how to invoke a javascript function from puppeteer which is not inline but in an external .js file. If its inline within the html->head->script tag it works but not if the script tag points to an external .js file
Sample HTML File
...ANSWER
Answered 2021-May-18 at 20:15First of all, [name="link"]
should be [name="arivalink"]
to match your DOM. I assume that's a typo.
As another aside, I recommend using the Promise.all
navigation pattern instead of waitForTimeout
which can cause race conditions (although this doesn't appear to be related to the problem in this case).
As for the main issue, the external file is working just fine, so that's a red herring. You can prove that by calling page.evaluate(() => fileFunction())
right after navigating to sample.html
.
The real problem is that when you navigate with window.location.replace('https://www.geeksforgeeks.org');
, Chromium isn't pushing that action onto the history stack. It's replacing the current URL, so page.goBack()
goes back to the original about:blank
rather than sample.html
as you expect. about:blank
doesn't have fileFunction
in it, so Puppeteer throws.
Now, when you click [name="link"]
with Puppeteer, that does push the history stack, so goBack
works just fine.
You can reproduce this behavior by loading sample.html
in a browser and navigating it by hand without Puppeteer.
Long story short, if you're calling a function in browser context using evaluate
that runs window.location.replace
, you can't rely on page.goBack
. You'll need to use page.goto
to get back to sample.html
.
There's an interesting nuance: if you use page.click
to invoke JS that runs location.replace("...")
, Puppeteer will push the history stack and page.goBack
will behave as expected. If you invoke the same JS logic with page.evaluate(() => location.replace("..."));
, Puppeteer won't push the current URL to the history stack and page.goBack
won't work as you expect. The evaluate
behavior better aligns with "manual" browsing (i.e. as a human with a mouse and keyboard on a GUI).
Here's code to demonstrate all of this. Everything goes in the same directory and node index.js
runs Puppeteer (I used Puppeteer 9.0.0).
QUESTION
In ExtJS by default, when one creates a view and an associated controller and then define an event like this myevent: 'onEvent'
the onEvent
in the controller is executed with the this
being the viewController.
Is it possible to have the this
be the view?
ANSWER
Answered 2021-May-12 at 15:08The way you're wanting it is not possible out of the box. However, you can set the listener's scope after your view is rendered. Fiddle for reference.

QUESTION
I use ExtJs 6.6.0 Classic. The grid component supports multi-column sorting (I use remoteSort: true, remoteFilter: true). Whenever the user clicks on a column header, that column becomes the first column in the order by list. But I cannot find how an end user is supposed to clear the sorting for a column. The context menu available through the column header doesn't have a "Clear Sort" option.
See also this kitchensink example.
I feel like I am missing something. There is a sortClearText config for the column inherited from the header, but I could not find a place where it's used (I thought that perhaps there is some config I can use to add the Clear Sort menu item to the column context menu).
I could add a button to execute the action of clearing the sorting of the store, as a last resort, but I don't like it.
Is there a simple way to add a Clear Sort option for a grid column through the Extjs components configuration?
Thank you
