Hi All,
I am trying to capture the tab selection event for a TabLayoutPanel
in my app which is based on MVP Pattern.
I have the following view,uiBInder & presenter. How ever when i
clicked on the Tab the event handler code is not getting processed !!
TabLayoutTestView.java
[VIEW]
public class TabLayoutTestView implements Display,
HasSelectionHandlers<Integer>
private static TabLayoutTestViewUiBinder uiBinder =
GWT.create(TabLayoutTestViewUiBinder.class);
@UiTemplate("TabLayoutTestView.ui.xml")
interface TabLayoutTestViewUiBinderextends
UiBinder<Widget,TabLayoutTestView> {}
@UiField TabLayoutPanel tabPanel;
TabLayoutTestView(){
initWidget(uiBinder.createAndBindUi(this));
}
public HasSelectionHandlers<Integer> getTabSelected() {
return this;
}
public HandlerRegistration
addSelectionHandler(SelectionHandler<Integer> handler) {
return addHandler(handler,SelectionEvent.getType());
}
[/VIEW]
TabLayoutTestView.ui.xml
[uiBInder]
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent";>
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<ui:style>
</ui:style>
<g:FlowPanel ui:field="tabContainer" height="100%">
<g:TabLayoutPanel barUnit="PX" barHeight="22"
ui:field="tabPanel"
height="100%">
<g:tab>
<g:header>Tab1</g:header>
<g:Label>Tab1 Contents</g:Label>
</g:tab>
<g:tab>
<g:header>Tab2</g:header>
<g:Label>Tab2 Contents</g:Label>
</g:tab>
<g:tab>
<g:header>Tab3</g:header>
<g:Label>Tab3 Contents</g:Label>
</g:tab>
<g:tab>
<g:header>Tab4</g:header>
<g:Label>Tab4 Contents</g:Label>
</g:tab>
</g:TabLayoutPanel>
</g:FlowPanel>
</ui:UiBinder>
[/uiBinder]
TabLayoutTestPresenter.java
[Presenter]
public class TabLayoutTestPresenter {
public interface Display extends View
{
HasSelectionHandlers<Integer> getTabSelected();
}
public TabLayoutTestPresenter (GreetingServiceAsync rpcService,
HandlerManager eventBus,Display display){
this.display = display;
this.rpcService = rpcService;
this.eventBus = eventBus;
}
public void bind() {
GWT.log(".bind() : TabLayoutTestPresenter ");
display.getTabSelected().addSelectionHandler(new
SelectionHandler<Integer>(){
public void onSelection(SelectionEvent<Integer>
event) {
GWT.log("Tab Selected
=["+event.getSelectedItem()+"]");
}
});
}
}
[/Presenter]
Thanks
