GWT UIBINDER TUTORIAL PDF

We will create a UiBinder screen composed of a java file Main. You can generate these files either by copying the following snippets, or by using the Eclipse GWT plugin. Note: Visit the original polymer elements documentation to learn and demo each component. Tip : to facilitate the usage of webcomponents gwt-polymer-elements maintains a couple of static constants: Element. TAG and Element. SRC , to avoid memorizing tag names and import paths respectively.

FinsShell is a custom widget which extends Composite and is the container for other parts of the layout. Dimensions of menu and content panel becomes fixed in size if they placed directly in DockLayoutPanel. To make them adjustable, menu is added to the west and contents to the center of a SplitLayoutPanel which is added to the center of the DockLayoutPanel.

With this design, we have fixed top and bottom sections and flexible middle section. FinsShell and various content pages which goes into content area are placed in a separate package and for this create a new package in.

Add FinsShell. We have placed Logo and Status label in a LayoutPanel as we want them at certain positions within their docks. LayoutPanel allows its children to be positioned using arbitrary constraints, almost like AbsolutePanel. As far as possible, it is good to avoid fixed or absolute constraints to position the widgets as such constraints are specified in percentage which ensures that widgets are adjusted when browser is resized.

SplitLayoutPanel is added to the center of dock. HTML widgets are added to west and center of this split panel as placeholders, for MenuBar and ContentPanel, which are replaced by actual widgets later. We are using fins-Logo-Label style to decorate the logo text. Create a new folder in in. It has to be a folder as it is not possible to create a package named public. Add Fins.

To add css to module use stylesheet element in fins. Layout Panels were introduced in GWT 2. All of these belongs to Layout Panels group. For now, you may ignore these subtle differences.

In FinsShell constructor we have called initWidget method of Composite. This method sets the widget to be wrapped by the Composite. Let us explain this with following code snippet. In the above example, the Composite WrapperWidget wraps the Label. With this, we can place WrapperWidget in any panel or even wrap it by other composites. Let us extend the example bit further. Widgets may be added to VerticalPanel either before or after calling initWidget, but initWidget has to be called before calling any other method of the Composite or using it with other composite or panels.

Coming back to our code, can you guess which widget is getting wrapped by FinsShell. UiBinder involves two files, template file and its owner class. Template file is a xml file with extension ui.

UiBinder generates objects declared in the template file and binds them to fields in owner class. In the owner class, following code initializes the UiBinder. UiBinder instances are factories that generate a UI structure and binds it to an owning Java class. When Binder.

Binder injects the widgets to UiFields defined in owner class FinsShell. GWT ; import com. UiBinder ; import com. UiField ; import com. Label ; import com. ResizeComposite ; import com. FinsShell ; import com.

Building the UI

However, I was having a hard time getting my head wrapped around it given that the GWT site has very little documentation and only a few examples. I've combed through the message boards, the docs and the sample Mail application that comes with the SDK and after finally groking the new functionality, I put together a little Hello World app, the kind that would have helped me out originally. If you are not, take a look at the GWT site for more info. Choose the client package for the project and then name it MyBinderWidget. Leave all of the other defaults. When you click Finish the plugin will create a new UiBinder template and owner class.

GWT UiBinder I18n – Tutorial – The easy way!

At heart, a GWT application is a web page. Besides being a more natural and concise way to build your UI than doing it through code, UiBinder can also make your app more efficient. UiBinder naturally takes advantage of this, and the result is that the most pleasant way to build your app is also the best way to build it. But as you learn what UiBinder is, you should also understand what it is not. It is not a renderer, or at any rate that is not its focus.
