I have a project that works modeled after the Contacts example from
the Google I/O talks.
In trying to use a DockLayoutPanel I changed the xxxx.ui.xml file as
from using simple panels
shown below. Both versions of the ui.xml file have the same UiFields.
Using the code below the application works.
<ui:UiBinder
xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:DecoratorPanel>
<g:VerticalPanel>
<g:HorizontalPanel
addStyleNames="{style.contactsViewButtonHPanel}">
<g:Button ui:field="addButton">Add</
g:Button>
<g:Button ui:field="deleteButton">Delete</
g:Button>
</g:HorizontalPanel>
<g:HTML ui:field="contactsTable"></g:HTML>
</g:VerticalPanel>
</g:DecoratorPanel>
</ui:UiBinder>
Changing it to the following breaks it, but I have not changed the
related java file.
(Error or warning message from debugger shown at end of topic.)
<ui:UiBinder
xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:DockLayoutPanel unit='EM'>
<g:north >
<g:HorizontalPanel
addStyleNames="{style.contactsViewButtonHPanel}">
<g:Button ui:field="addButton">Add</
g:Button>
<g:Button ui:field="deleteButton">Delete</
g:Button>
</g:HorizontalPanel>
</g:north>
<g:center>
<g:HTML ui:field="contactsTable"></g:HTML>
</g:center>
</g:DockLayoutPanel>
</ui:UiBinder>
In the java file I did **NOT** make **ANY** changes because I think
the UiBinder handles it for me.
Here is the relevent code from the java impl file
public class DashboardViewImpl<T> extends Composite
implements DashboardView<T> {
@UiTemplate("DashboardView.ui.xml")
interface DashboardViewUiBinder extends UiBinder<Widget,
DashboardViewImpl> {}
private static DashboardViewUiBinder uiBinder =
GWT.create(DashboardViewUiBinder.class);
@UiField HTML contactsTable;
@UiField Button addButton;
@UiField Button deleteButton;
private Presenter<T> presenter;
...
public DashboardViewImpl() {
initWidget(uiBinder.createAndBindUi(this));
}
......
@UiHandler("addButton")
void onAddButtonClicked(ClickEvent event) {
....
}
@UiHandler("deleteButton")
void onDeleteButtonClicked(ClickEvent event) {
....
}
@UiHandler("contactsTable")
void onTableClicked(ClickEvent event) {
....
}
public Widget asWidget() {
return this;
}
}
===============================
When I run the application I get an error or warning messages that
probably relate to the problem,
but I don't understand them
- Rebinding com.google.gwt.core.client.impl.SchedulerImpl
- For the following type(s), generated source was never committed
(did you forget to call commit()?)
-
com.wbc.dashboardtwo.client.DashboardViewImpl_DashboardViewUIBinderImpl
I don't get that message with the first xxxx.ui.xml file, just the
second.
Any help is appreciated.
Thanks in advance...
Jim
