Getting Started

To use GWT DateBox in your GWT application, you first need to add the GWT DateBox library to your project's classpath. You can do this by adding the following line to your project's pom.xml file:

<dependency>
    <groupId>com.google.gwt.user</groupId>
    <artifactId>gwt-datetime</artifactId>
    <version>2.8.2</version>
</dependency>

Once you have added the library to your project, you can start using the DateBox widget in your application. Here's a simple example:

DateBox dateBox = new DateBox();
RootPanel.get().add(dateBox);

This will add a DateBox widget to your application, which will display a calendar for selecting dates when the user clicks on it.

Customization

GWT DateBox allows you to customize the widget to match the look and feel of your application. You can do this by using CSS styles to change the appearance of the widget. For example, you can change the background color of the widget like this:

.gwt-DateBox {
    background-color: #eee;
}

You can also customize the widget's date format and locale by setting the DateBoxFormat instance for the widget. For example, here's how you can set the widget to use the "dd MMM yyyy" date pattern and the French locale:

DateBox dateBox = new DateBox();
dateBox.setFormat(new DateBox.DefaultFormat(DateTimeFormat.getFormat("dd MMM yyyy"), DateTimeFormat.getFormat("dd MMM yyyy"), new DateTimeFormatInfoImpl_fr()));
RootPanel.get().add(dateBox);

Conclusion

GWT DateBox is a powerful and flexible widget for selecting and manipulating dates in GWT applications. With its support for customizable date formats and locales, keyboard navigation, and easy integration into GWT projects, it provides a fast and efficient way to work with dates in your applications.
