In Vaadin 8 framework, using Vaadin Grid, how do I present a Boolean object in each row as a checkbox?
Display a Unicode character
An alternative to the other correct Answer is: plain text. Display one of the Unicode characters representing checkboxes on either state, checked or unchecked.
Write code that chooses one or the other for the Boolean value. Write the code as a column renderer, specifically a TextRenderer.
I think the easiest solution is to use the ComponentRenderer introduced with Vaadin 8.1 (currently beta, so you need to get it from snapshot repository). See Vaadin docs: https://vaadin.com/docs/-/part/framework/components/components-grid.html#components.grid.renderer.
Example with VaadinIcons
grid.addColumn(user -> user.isFreeUser() ? VaadinIcons.CHECK.getHtml() : null)
.setRenderer(new HtmlRenderer())
.setCaption("Free User");

Is it possible to set the dropdown display style in apps script?
After checking the documentation it looks like the API only allows you to choose between "Arrow" and "Plain Text".
The Apps Script documentation explains how to create data validation rules with a DataValidationBuilder. Most of the methods just set different DataValidationCriteria. Among those, the methods requireValueInList() and requireValueInRange() are the only ones that have a showDropdown parameter to set a dropdown, and the parameter's values can only be true or false. The default is true, which is equivalent to "Arrow" and false is equivalent to "Plain Text". As a boolean there's no third option for "Chip". Example:
// Set the data validation for cell A1 to require "Yes" or "No", with a dropdown menu.
var cell = SpreadsheetApp.getActive().getRange('A1');
var rule = SpreadsheetApp.newDataValidation().requireValueInList(['Yes', 'No'], true).build();
cell.setDataValidation(rule);
Looking at the Sheets REST API, which Apps Script is built on, the DataValidationRule works in a similar way, but this uses showCustomUi instead of showDropDown. Still, the limitation is the same to show only the basic arrow and plain text.
It just seems like a feature that hasn't been implemented yet. Maybe the "Chip" was added a while after the basic dropdown. You can try to request it in Google's issue tracker.
How can I change the language for Sorting on PF DataTable component with reflow = "true" (so responsive Datatable)?
The problem is that on mobile screen, we can sort data from auto-generated dropdown where we have our sort options, see picture bellow. How can I change the language for this dropdown?
I'm using PF 6.0.
The intended way to do this is to define the following properties in your resource files (see Messages.properties)
primefaces.datatable.SORT_LABEL = Sort
primefaces.datatable.SORT_ASC = Ascending
primefaces.datatable.SORT_DESC = Descending
You can see this when you look at the DatatableRender of primefaces.
Notice i18n is done in different ways in primefaces. Some components like calendar or schedule must be translated via javascript. See here
I never ran into this or used it, but I know the source is open. So I went to the javascript file for the datatable. There I searched for 'Ascending' and via this.ascMessage, I ended up on line 170 where 'datatable.sort.ASC' is used as a key.
This in turn points to line 619 in core.js
getAriaLabel: function(key) {
var ariaLocaleSettings = this.getLocaleSettings()['aria'];
return (ariaLocaleSettings&&ariaLocaleSettings[key]) ? ariaLocaleSettings[key] : PrimeFaces.locales['en_US']['aria'][key];
},
Where you can see the normal PrimeFaces locale functionality is used.
So using your own locale and overriding this part in it, like in the default locale
aria: {
'paginator.PAGE': 'Page {0}',
'calendar.BUTTON': 'Show Calendar',
'datatable.sort.ASC': 'activate to sort column ascending',
'datatable.sort.DESC': 'activate to sort column descending',
'columntoggler.CLOSE': 'Close'
}
Will solve your issue I would expect

I have textarea which is required field. I've found post suggesting that Dojo doesn't have validation for Textarea, but in Dojo 1.9, there's an argument 'required'.
I've done the following:
new Textarea({required:true, value:""}, query('[name=description]')[0])
but the effect isn't what I've expected. The texarea has red border always, even if the field wasn't focused (as opposite to, for example, ValidationTextBox). But when I call:
form.validate()
the validation is passed even if the texarea is empty.
Is it possible to get Textare behave the same as in ValidationTextBox, or as for now, the validation for that component is not yet ready and I'd have to write custom version (as in linked post) or wait for next Dojo?
I've done it using mixin of SimpleTextArea and ValidationTextArea:
define(["dojo/_base/declare", "dojo/_base/lang", "dijit/form/SimpleTextarea", "dijit/form/ValidationTextBox"],
function(declare, lang, SimpleTextarea, ValidationTextBox) {
return declare('dijit.form.ValidationTextArea', [SimpleTextarea, ValidationTextBox], {
constructor: function(params){
this.constraints = {};
this.baseClass += ' dijitValidationTextArea';
},
templateString: "<textarea ${!nameAttrSetting} data-dojo-attach-point='focusNode,containerNode,textbox' autocomplete='off'></textarea>"
})
})

The power of Dojo lies in extending it with ease. If you really need the required functionality, then implement it. If you design it well, there should be no problem if it actually gets implemented in a new release of Dojo.
If you really want to know if such a feature exists or is in development I suggest looking at http://bugs.dojotoolkit.org. Besides, you can always contribute to the code, that's what open source is meant for.
I would like to add to the answer of Donaudampfschifffreizeitfahrt
instead of "this.baseClass += ' dijitValidationTextArea';"
I would do
this.baseClass = this.baseClass.replace('dijitTextBox', 'dijitValidationTextArea');
because
• we do not need the TextBox class if we have got a textarea mixin
• ! the "rows" parameter is mixed in but not fired/styled if the TextBox class is present ...
I'm a QA, and I'm new to android automation as such, and I am having problem in automating the spinner / Dropdown related activities in my app. I am using Robotium 4.1 for my automation.
The Spinner in my app is implemented using actionbarsherlock. The Hierarchyviewer shows it as Popupwindow:SOME-RANDOM-ID. It looks like the implementation is internal to actionbarsherlock. After talking to the dev he tells me that it's a "non-visible" element. I don't understand what that means, because I can see the element.
Also, I can't find the methods mentioned in some of the other questions here.
I suppose the right way is to use solo.getViews(), and solo.getCurrentViews etc. but I don't know how to use the parameters in there, so whatever I tried didn't work.
Can someone guide me with a detailed example? (including how to give the parameters to getViews etc will be much appreciated.)
How to get number of items:
mSpinner.getAdapter().getCount();
How to click on specified item on spinner:
solo.pressSpinnerItem(indexOfSpinner, indexOfItem);
How to get current spinners:
ArrayList<Spinner> currentSpinners = solo.getCurrentViews(Spinner.class);
How to get spinner with specified index:
Spinner spinner = getView(Spinner.class, index);
