我正在使用GWT MVP和UiBinder創建一個帶有DockLayoutPanel的應用程序。我希望南北碼頭是靜態的,包含按鈕和鏈接。我希望在東碼頭的中心和兩個不同的區域有動態的視野。由於這些動態區域應該彼此獨立,因此我爲每個動態顯示區域設置了不同的ActivityMapper和ActivityManager;中心,東邊和東邊。如何:UiBinder + GWT MVP +多個獨立顯示區域
如何在應用程序加載時獨立初始化這3個不同的顯示區域?如何在一個顯示區域中從一個活動切換到另一個活動而不影響其他區域?
當我使用PlaceController的goTo從一個區域切換到另一個區域時,其他區域的Activity停止。
五月天,請幫助,五月天!
以下是我的一些代碼:
AppViewImpl.ui.xml
<g:DockLayoutPanel styleName="{style.dockPanel}" unit="PX" width="975px" height="100%">
<!-- DOCK PANEL EAST -->
<g:east size="220">
<g:LayoutPanel styleName="{style.eastPanel}">
<g:layer left="0px" width="220px" top="0px" height="105px">
<g:SimpleLayoutPanel ui:field="topRightPanel"/>
</g:layer>
<g:layer left="0px" width="220px" top="110px" height="340px">
<g:InlineLabel styleName="{style.label}" text="ANOTHER DISPLAY AREA"/>
</g:layer>
</g:LayoutPanel>
</g:east>
<!-- DOCK PANEL NORTH -->
<g:north size="110">
<g:LayoutPanel styleName="{style.northPanel}">
<g:layer left="0px" width="755px" top="0px" height="105px">
<g:InlineLabel styleName="{style.label}" text="NORTH PANEL"/>
</g:layer>
</g:LayoutPanel>
</g:north>
<!-- DOCK PANEL SOUTH -->
<g:south size="20">
<g:LayoutPanel styleName="{style.southPanel}">
<g:layer left="0px" width="755px" top="0px" height="20px">
<g:InlineLabel styleName="{style.label}" text="SOUTH PANEL"/>
</g:layer>
</g:LayoutPanel>
</g:south>
<!-- DOCK PANEL CENTER -->
<g:center>
<g:SimpleLayoutPanel ui:field="mainPanel" />
</g:center>
</g:DockLayoutPanel>
MyModule.java
公共類MyModule的實現入口點{
private Place defaultPlace = new DefaultPlace("");
public void onModuleLoad() {
// Create ClientFactory using deferred binding so we can replace with
// different impls in gwt.xml
ClientFactory clientFactory = GWT.create(ClientFactory.class);
EventBus eventBus = clientFactory.getEventBus();
PlaceController placeController = clientFactory.getPlaceController();
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper topRightActivityMapper = new TopRightActivityMapper(clientFactory);
ActivityManager topRightActivityManager = new ActivityManager(topRightActivityMapper, eventBus);
topRightActivityManager.setDisplay(clientFactory.getAppView().getTopRightPanel());
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper mainActivityMapper = new AppActivityMapper(clientFactory);
ActivityManager mainActivityManager = new ActivityManager(mainActivityMapper, eventBus);
mainActivityManager.setDisplay(clientFactory.getAppView().getMainPanel());
// Start PlaceHistoryHandler with our PlaceHistoryMapper
AppPlaceHistoryMapper historyMapper = GWT .create(AppPlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new PlaceHistoryHandler(historyMapper);
historyHandler.register(placeController, eventBus, defaultPlace);
RootLayoutPanel.get().add(clientFactory.getAppView());
// Goes to place represented on URL or default place
historyHandler.handleCurrentHistory();
new AppController(clientFactory);
}
}
AppController.java
public class AppController implements AppView.Presenter {
private ClientFactory clientFactory;
AppController(ClientFactory clientFactory){
this.clientFactory = clientFactory;
goTo(new TopRightAPlace(""));
}
@Override
public void goTo(Place place) {
clientFactory.getPlaceController().goTo(place);
}
}
TopRightAViewImpl.java
public class TopRightAViewImpl extends Composite implements TopRightAView {
interface Binder extends UiBinder<Widget, TopRightAViewImpl> {
}
private static final Binder binder = GWT.create(Binder.class);
private Presenter listener;
@UiField
Button button;
public TopRightAViewImpl() {
initWidget(binder.createAndBindUi(this));
}
@Override
public void setName(String name) {
button.setHTML(name);
}
@Override
public void setPresenter(Presenter listener) {
this.listener = listener;
}
@UiHandler("button")
void onButtonClick(ClickEvent event) {
listener.goTo(some other place);
}
}
這正是我最終做的。謝謝! – Pete
