It's very hard to find questions about GWTP (GWT Platform).
Ok, Here is my Story. I am using GWTP & eclipse to create the
Presenter-View structure automatically.
Example, I created a TestPresenter in eclipse, & it created 3 files:
TestPresenter.java, TestView.java, TestView.xml
In TestView.xml, i have:
<g:RadioButton ui:field="firstRadioButton" value="false" text="1st" />
<g:RadioButton ui:field="secondRadioButton" value="false" text="2nd" />
<g:RadioButton ui:field="bothRadioButton" value="true" text="Both" />
Now I want to set the GroupName automatically for each TestView, so in
TestView.java
public class TestView extends ViewImpl implements
TestPresenter.MyView {
private final Widget widget;
@UiField RadioButton firstRadioButton;
@UiField RadioButton secondRadioButton;
@UiField RadioButton bothRadioButton;
private String groupName;
@UiFactory
RadioButton makeRadioButton() {
return new RadioButton(groupName);
}
public interface Binder extends UiBinder<Widget, TestView> {
}
@Inject
public TestView(final Binder binder) {
widget = binder.createAndBindUi(this);
}
@Override
public Widget asWidget() {
return widget;
}
public RadioButton getFirstRadioButton() {
return firstRadioButton;
}
public RadioButton getSecondRadioButton() {
return secondRadioButton;
}
public RadioButton getBothRadioButton() {
return bothRadioButton;
}
}
In TestPresenter.java,
public class TestPresenter extends
PresenterWidget<TestPresenter.MyView> {
public interface MyView extends View {
public RadioButton getFirstRadioButton();
public RadioButton getSecondRadioButton();
public RadioButton getBothRadioButton();
}
}
Ok, finally I want to use many TestPresenter (by using setInLot) in
MainPresenter.java
So, in MainPresenter.java, I have:
public static final Object SLOT1=new Object();
public static final Object SLOT2=new Object();
public static final Object SLOT3=new Object();
public static final Object SLOT4=new Object();
//...... more lot
@Inject TestPresenter testPresenter1;
@Inject TestPresenter testPresenter2;
@Inject TestPresenter testPresenter3;
@Inject TestPresenter testPresenter4;
//.. more test presenter
in MainView.java, i have setInSlot
@UiField HTMLPanel mainHtmlPanel;
@Override
public void setInSlot(Object slot, Widget content){
if(slot==TestPresenter.SLOT1){
mainHtmlPanel.clear();
if(content!=null){
mainHtmlPanel.add(content);
}
}
else if(slot==TestPresenter.SLOT2){
mainHtmlPanel.clear();
if(content!=null){
mainHtmlPanel.add(content);
}
}
//... more else if here
}
Now, if i just do like that then I can not pass the groupName separately
for each TestPresenter & that is not good. So I want to pass the groupName
string for each TestPresenter so that each will have their own groupName.
SOmething like this
@Inject TestPresenter testPresenter1 ("group1");
@Inject TestPresenter testPresenter2 ("group2");
@Inject TestPresenter testPresenter3 ("group3");
@Inject TestPresenter testPresenter4 ("group4");
...
but I don't know how to it properly, so please tell me how to it properly
in GWTP?
