Hi to All!!!

So we have API:
-TextField;
-DateField
…atc

but what about
-IntegerField
-DecimalField (for locale)

I missed something…

Please advice what should I do to have an ability to input numbers in editor

does this help?

Definitely would be awesome to have this as vaadin core & ui polished to match vaadin’s other widgets. Spinners are common widgets.

I’m assuming you want to be able to enter numeric values and have them formatted correctly.

You can format values in a TextField by using a PropertyFormatter - this will ensure the text is converted to and from the Property in a given format - i.e. it parses the text the user entered, and converts into an object, and also formats an object into text for display.

You can easily implement a PropertyFormatter that delegates to a DecimalFormat to give locale-specific numeric formatting. It essentially operates as a converty proxy between the field and the underlying property.

PropertyFormatters will not prevent you from entering non-numeric characters in the browser (client), mind you. There are various add-ons in the directory that might be of use in this regard. I’ve not used any of them myself, yet

http://vaadin.com/directory#addon/dwtextfields (Has a decimal text field)
http://vaadin.com/directory#addon/autoreplacefield (Has integer field, and allows replacement of text on client side via regex)
http://vaadin.com/directory#addon/maskedtextfield (Enter according to a mask)

HTH,

Hi,

I’ve downloaded one of the add ons. As I see now, its quite easy to implement a digits only field. And I think, a good API fitting all needs in all situations would be hard to design. Still, a hint how to do it would be nice in die JavaDoc or in the Vaadin books. In business applications an Integer field where you can enter letters makes a terrible impression. So its quite an important thing to have a key filter.

Here is my investigation on available addons for numeric fields, that prevent the user to input others things than digits and accepting double values :


Dw textfield
 : Weird to use

Auto replace field
 : Simple and nice, only a slight problem of rendering and selection

Masked TextField
 : Handle only masks, I needed something to prevent the user to enter character others than digits.

Numeric field
 Compiled in Java 7…

Ikarus
 : Not a fan of the numeric field, weird stuff happens when entering numbers, and integration with maven is bad
