DatePickjer dialogbox widget that displays a small Gregorian calendar dates to select a date by the user.

Any date can be choosen the start date and the month grid. Today's date is the default selection and also the default displayed month.

Cyril Balit compares the grids in the three various technologies: Flex, GWT and ExtJS. He writes:

«The title is a little a canvasser but the purpose of this post is rather to get acquainted with 3 manners to make RIA and to compare them through a central component of an application: the grid.
I was thus used to recreate a simple screen containing a label, a button and a grid. »

Julien Viet wrote an article in whi he shows how to build in place editor with GWT. He writes:

«The in place editor is one of the simplest yet powerful feature brought by Ajax.

I wrote two such editors last year, one using javascript and one leveraging Prototype as an exercise. Recently I started to study GWT more in depth and I found fun to write a GWT version of the in place editor.

I used the TextBox and Label widgets that will be used to display and edit the label.

The DeckPanel panel is used to alternate the display between the text box and the label widgets.

The interaction is performed using listeners. The ClickListener on the label copies the label value to the text box and switch the deck panel to show the text box. The KeyboadListener allows on the enter keystroke to copy the edited value to the label and switch back the deck panel to show the label.»
