In my Vaadin application I need to present several tables. They are similar in structure but have different headers. In plain old HTML I would specify those headers in the thead section of table.
I did look for something similar in Vaadin Grid, but didn't find anything similar.
I certainly can separate tables with Label, but wonder if I did miss something and this feature does exist.
Please enlighten me.
Not sure I understand what you're looking to do, but the Vaadin Grid component does have a <thead> element (see screenshot) – but the API hides it behind its own abstractions. Instead of creating it directly, you specify a header for each column, which will then generate <th> elements inside the Grid's <thead>, e.g.
grid.addColumn(Person::getFirstName).setHeader("First name");

I'm using CKEditor5. I'm looking for a plugin to extend its functionalities to manage columns (not <table>, but div or whatever suitable element for layout purpose). I just can't find anything like that.
Any idea to achieve that? Should I implement my own plugin to do that?
Very new to bootstrap and it seems so cool, but as I look around at various templates, I feel I am missing the "template" nature of the code.
How does one build on the sample templates to have, for example, a master index page and reusable components (tabs, sidebars, menus, headers, footers) available to all "rendered" pages? It does not seem efficient to recode sidebar menus into every page but that's what the samples seem to show.
Perhaps there is a way to have a special div where the variable content can be loaded?
Or, perhaps there is a higher level framework I should be looking at and bootstrap is not the answer for what I need?
All the elements in the application which i am testing have dynanic ID's . The test always passes when i replay it without refreshing the page but as soon as i refresh the page, The Test Fails because Id's of all the elements changes randomly and selenium cannot match the recorded id's with the new ones .
I tried to use Xpath-position, It works for some objects but in case of Dropdown list and Buttons, it dosent work!
Can anyone please tell me how to find the Xpath (Meathods in JAVA or S*elence*) of an object OR How to create a new Locator Finder for Dropdown list and Buttons
I can show the properties (Inspected by Firebug) of the dropdown which is teasing me.
properties of Dropdown :
<div id="ext-gen1345" class="x-trigger-index-0 x-form-trigger x-form-arrow-trigger x-form-trigger-last x-unselectable" role="button" style="-moz-user-select: none;"></div>
properties of Dropdown*Choice*:
<ul>
<li class="x-boundlist-item" role="option">Rescue</li>
</ul>
Please search before posting, I have been answering this over and over.
ExtJS pages are hard to test, especially on finding elements.
Here are some of the tips I consider useful:
Don't ever use dynamically generated IDs. like (:id, 'ext-gen1345')
Don't ever use absolute/meaningless XPath, like //*[#class='someclass']/li/ul/li[2]/ul/li[2]/table/tbody/tr/td[2]/div
Take advantage of meaningful auto-generated partial ids and class names. (So you need show more HTML in your example, as I can make suggestions.)
For example, this ExtJS grid example: (:css, '.x-grid-view .x-grid-table') would be handy. If there are multiple of grids, try index them or locate the identifiable ancestor, like (:css, '#something-meaningful .x-grid-view .x-grid-table'). In your case, (:css, '#something-meaningful .x-form-arrow-trigger')
Take advantage of button's text.
For example, this ExtJS example: you can use XPath .//li[contains(#class, 'x-boundlist-item') and text()='Rescue']. However, this method is not suitable for CSS Selector or multi-language applications.
The best way to test is to create meaningful class names in the source code. If you don't have the access to the source code, please talk to your manager, using Selenium against ExtJS application should really be a developer's job. ExtJS provides cls and tdCls for custom class names, so you can add cls:'testing-btn-foo' in your source code, and Selenium can get it by (:css, '.x-panel .testing-btn-foo').

I would suggest you build a xpath from any of the parent of your DIV. you may get messed if there is no immediate parent node has such one.
example,
//*[#id='parentof div']/div
//*[#class='grand parent of div']/div/div
i did even something like this,
//*[#class='someclass']/li/ul/li[2]/ul/li[2]/table/tbody/tr/td[2]/div
But still, its not encouraged to do so.
I was experimenting with Dojo and Dijit in the past days and I find it quite interesting. I was however trying to find a reference or an API doc that helps me understand all the properties I can assign to widgets and containers.
For example a Tab with a Save Icon will be like this:
<div data-dojo-type="dijit.layout.ContentPane" title="Group Two" data-dojo-props="iconClass: 'dijitEditorIcon dijitEditorIconSave'">
Now, where can I find what to put in the "data-dojo-props" property? Where can I find for example all the list of icons?
My main question would be for example on how to create a vertical menubar, but beyond odd examples scattered here and there, the api reference is not much helpful...
Any help? Am I missing something here?
For this kind of situation, the trick is learning how to convert between the programmatic Javascript style and the declarative HTML style (and sometimes also between the old declarative style, without data).
For the new declarative style, basically the only "real" argument now is data-dojo-props and it consists of an object that will be passed to the widget constructor.
//programatic style
new dijit.myWidget({foo:'a', bar:'b'});
//declarative style
<div data-dojo-type="dijit.myWidget" data-dojo-props="foo:'a', bar:'b'"></div>
You can find what properties an widget accepts by checking the corresponding widget documentation and looking for either declarative or programmatic examples (now that we know how to convert between them). If that is not enough, you can also check the source code - it is usually very well commented and is where api.dojotoolkit.org gets its data from anyway.
In asp.net the DataGrid supports templates. You can provide your own template and have the grid fill the data in your template.
With Dojo Grid, it seems like I can't make my own template outside of the the rigid simplistic cell style grid that Dojo provides.
Does anyone know a way to use a custom template with Dojo Grid? Specifically, with Dojo you're forced to use a cell that corresponds to a data item. I'm looking to use a table as a template with any styling that I choose (rows,columns,rowspans,colspans, more than one data items in a single cell, etc).
Any clues please?
Thanks
Firstly, it sounds like everything you want is available by customizing the grid. You can do nesting of cells and even have things like Filtering Selects in rows. Unfortunately the docs on this are not awesome so it takes Googling and trial and error if you want very customized features.
Secondly, because of the OO nature of Dojo you can always use inheritance to create mixes of various widgets. Specifically the _templated class allows you to specify an HTML template for your widget, which themselves can included templated widgets.
If that sounds non-trivial, you're right, which is why I would suggest digging deeper into the Enhanced grid and probably open up the code before trying to write something yourself.
I can tell you that I struggled getting it working correctly, but I have hence been pleasantly surprised by features that I needed that I thought I would need to build myself but were built into the grid.
