How to add ValueChangeHandler to Tree?
Hi,
as far as I can see a GWT Tree has no ValueChangeHandler by default (for
modifying elements in the tree).
Therefore I'm trying to extend the Tree and add a ValueChangeHandlermy myself.
But it never get's called:
class MyTree extends Tree implements ValueChangeHandlerString {
//never gets called
@Override
public void onValueChange(ValueChangeEventString event) {
System.out.println(value changed);
}
}
What's wrong here?
I'm changing the trees' content with:
@UiBinder
TextBox box;
@UiBinder
Button save;
@UiHandler(save) {
void onSave(ClickEvent evt) {
tree.getSelectedItem().setText(box.getText());
}
From debugging I can see that the value in the tree items is already
changed by this! But it is not reflected in the tree in GUI. So I probably
have to write something in the onChangeHandler to update the tree visually.
But as I said, onValueChange never gets called...

Re: Code Splitting Simple Example Still getting Thrown into Left Overs
Jens, thanks for the input.

Prior to A being downloaded, Activity B is started and downloads or loads faster than A So A will set the display panel AFTER Activity B - The default ActivityManager will give control to A and kill of B even though we probably want to give B the control and display since A took longer loading and setting the display... I am not sure if my logic fits reality, but I have extended Saeed's asyncMapper/Manager example to use the Place to determine what activity gets control (That last place fired gets control.

In MVP is there a difference between declaring the 'binding' interface in the presenter versus the view?
I saw a lot of sample code, most of them use the following way of creating
MVP:
public interface ContactsViewT {
public interface PresenterT {
void onAddButtonClicked();
void onDeleteButtonClicked();
void onItemClicked(T clickedItem);
void onItemSelected(T selectedItem);
}
void setPresenter(PresenterT presenter);
void setColumnDefinitions(ListColumnDefinitionT columnDefinitions);
void setRowData(ListT rowData);
Widget asWidget();
}
Then let the presenter implement ContactsView.PresenterContact. However
some do the following:
public class ContactsPresenter implements Presenter {
public interface Display {
HasClickHandlers getAddButton();
HasClickHandlers getDeleteButton();
HasClickHandlers getList();
void setData(ListString data);
int getClickedRow(ClickEvent event);
ListInteger getSelectedRows();
Widget asWidget();
}
//.
}
Then let the view implement the ContactsPresenter.Display.
Are there any good points for doing either methods, maybe one is better
suited for UiBinder?
2- Another question, is the view not suppose to directly communicate with
the model at all. For instance, if I've got a ListBox that should
be populated from an Enum class that sits in the model, should that be done
through the presenter?

Re: Some of my images arnt being turned into image strips :?
Still no luck.
If it helps diagnose I can supply sample images.

What baffles me is they are defined the same way as others that do

eg. I have a file like:

...
@Source(/MemorableDayIcons/MEDIUM/magrietbag0.png)
ImageResource MEDmagrietbag0();
@Source(/MemorableDayIcons/MEDIUM/magrietbag1.png)
ImageResource MEDmagrietbag1();
@Source(/MemorableDayIcons/MEDIUM/magrietbag2.png)
ImageResource MEDmagrietbag2();
...
Which makes a lovely image strip that animates really smoothly.
I have another group of sprites however:
public interface NoirInternalSprites extends ClientBundle {
@Source(com/darkflame/client/JargScene/firelopp/fireloop0050.png)
ImageResource fireloop0050();
@Source(com/darkflame/client/JargScene/firelopp/fireloop0051.png)
ImageResource fireloop0051();

ImageResource fireloop0052();
@Source(com/darkflame/client/JargScene/firelopp/fireloop0053.png)
ImageResource fireloop0053();
...
Which does not.
These pngs instead turn into dozens of separate files - not a image
strip at all.
So what gives :?
What determines when images are combined and when they are not ?
For reference, I use
set-property name=ClientBundle.enableInlining value=false /
in my gwt.xml to stop data urls being formed.
Thanks for any pointers,

Re: GWT - Crawlable (SEO)
I can only comment how I did it; Googles bot will read any url in the form: #!key1=value1key2=value2 As: ?_escaped_fragment_=key1=value1%26key2=value2 Thus I built a php version of my site that delivered the same content without the need for JavaScript. By using escape fragments the same request data is avaliable to the server as the client, so you should be able to pull up the same contents as the client. (for example, from a mysql database). So effectively the javascript and php versions of my site mirror eachother in terms of content, and the bot has access to the php one via the ?_escaped_fragment_ url standard.

In brief: the former makes it way easier to mock the view to unit-test your
presenter. And if you don't put getters in your view, the source of truth
will be your presenter, and your view will only be considered a… view, of
the same data.

I don't think any purist would tell you your view shouldn't *know* about
the model. What you should not do is a) pull data from the view, b) update
the model from the view, or c) listen to model changes in the view;
everything should go through the presenter: it holds data *to* the view,
the view asks the presenter to modify the model, and the presenter possibly
observes model changes and reflects them in the view.

Wrt UX, I would consider automatically reloading the app a bad practice. It could be done in browsers that let you detect when the app is in the background, but you'd still have to be sure that I don't have any unsaved data and for best UX restore the exact same screen: same scrolling position, same open/closed items, same focused widget and element in list, etc. In the end, just let the user reload, it way much easier and he knows there'll be side effects. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

It looks like Groups doesn't use type name elision? I see some FQCNs like java.util.List, but not as many FQCNs as in our non-type-name-elided messages. Makes me wonder if Google shares serialization policy files cross builds? This seemed kinda tricky to setup in an intelligent way (would want to ignore CI/non-production serilalization files, wouldn't want to keep them forever, etc.), so currently I don't share policy files across builds. Which means I can't use type name elision (well, without more forced refreshes, vs. when-they-feel-like-it refreshes). - Stephen -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Code Splitting Simple Example Still getting Thrown into Left Overs
If you don't mind me asking,
- Do you link Activities directly to specific places: ActivityP extends
Place ?
- Somewhat related, do you set an actual place (constructor/setter) or
just a particular param (DTO/other object/variable)?
Yes I do. Its like
interface CustomActivity extends ActivityP extends Place {
void setPlace(P place);
}
Along with an abstract CustomActivityBase class that implements this
interface and adds some protected isActive logic: the activity is
considered inactive if cancel/stop is called so that any RPC call and its
onSuccess() code will be disabled in the activities start() method (user
navigates away before RPC returns):
onSuccess(..) {
if(isActive()) {
...//proceed
}
}
- Do you have a lot of ActivityWithPlaceProxy boiler plate?
Its more or less the usual if-construct to instantiate the correct activity
for a given place in the ActivityMapper. There is a bit additional code
because of the complete mappers I code split (see below).
- Do you show any loading on the ActivityWithPlaceProxy.start() prior to
the actual start of the desired activity?
Not yet. Depending on how you want to notify your users you could:
1.) Implement a custom AcceptsOneWidget/SimplePanel/SimpleLayoutPanel that
shows a loading text/icon in the display area when no child widget is set
(on construction and on setWidget(null)).
2.) Fire a custom event on the event bus and let a global notification
mechanism listen for it.
- I Assume by proxy complete mappers you mean: build a proxy mapper
delivered via AsyncProvider which will pull all activities in that mapper
at once??
Its a normal ActivityMapper having Gin ProviderConcreteActivity as fields
and the usual dispatch code in getActivity(Place). You then have a slightly
different implementation of your AsyncActivityWithPlaceProxy that does not
use an AsyncProviderCustomActivity but an AsyncProviderActivityMapper
and loads the mapper in the proxy's start() method. When the mapper is
loaded you get the correct Activity from the mapper using the place that
has been set to the proxy through the ActivityMapper that is assigned to
the ActivityManager and finally start the activity.
Obviously the ActivityMapper assigned to the ActivityManager has to catch
all possible places for that async mapper hidden in the activity proxy:
getActivity(Place place) {
if(place instanceof ConcretePlace1 || place instanceof ConcretePlace2 ||
...) {
AsyncActivityWithPlaceAndMapperProxy activity = //...
activity.setPlace(place) // the internal mapper will dispatch the
place to the correct activity.
}
}
You could mitigate that by introducing a common super class (or marker
interface) for places that are handled by the same async ActivityMapper.
- It would appear there is a situation when using activities provided via
RunAsync that the default ActivityMapper behavior is not desired:
--- In non-RunAsync, if a new Activity starts AND sets the display
widget/panel prior to the activity which preceded it (user navigates before
current activity can set display), clear/kill current activity and proceed
with next
However, this is not the same when RunAsync is involved as Activity
A can be called and downloaded. Prior to A being downloaded, Activity
B is started and downloads or loads faster than A
So A will set the display panel AFTER Activity B - The default
ActivityManager will give control to A and kill of B even though we
probably want to give B the control and display since A took longer
loading and setting the display...
I am not sure if my logic fits reality, but I have extended Saeed's
asyncMapper/Manager example to use the Place to determine what activity
gets control
(That last place fired gets control. So if an activity loads but is
linked - pass the Place as params through the async calls - to a different
place, kill it)
The activity that is active is your AsyncActivityProxy. The start() method
(maybe) does an async RPC call like most ordinary Activities probably also
do to load some data. So your AsyncActivityProxy should also have the same
isActive logic like an ordinary activity. So in onSuccess() of
GWT.runAsync() you do:
if(isActive()) { //false if cancel/stop has been called on the proxy while
activity is downloaded
activity.setPlace(place);
activity.start(panel, eventbus);
}
Only the activity that is currently active in the ActivityManager will win
because the previous one will not proceed if the download completes to late
(isActive() is false). Am I missing something?
Speaking in menu items I use the async ActivityMapper to generate a single
split point that contains all the sub menu items of a single main menu
item. As soon as an Activity for a given sub menu item gets too large I
remove it from the async ActivityMapper and code split it separately.
Feel free to ask more :-)

You received this
opera deserialization problem
Hi,
I've got an interesting problem I can reproduce only in opera browser
(12.12). Chrome, Firefox, IE looks ok.
On rpc call (pretty much any RPC call with custom classes or collections) I
see the following exception on client side:
https://lh4.googleusercontent.com/-EdzZSzDwYfs/UOwOwXXCYGI/Amw/ehJv4lcO0xo/s1600/rpc-error.jpg
I'm running gwt 2.5 and smartgwt 3.1 (don't think smartgwt is anyhow
involved though). Behaviour was exactly the same on gwt 2.4.
Simplified class looks like this - sorry for bad formatting:
public class UserSessionInfo implements IsSerializable {
private String userName;
private PlannerRole role = PlannerRole.ADMINISTRATOR;
public PlannerRole getRole() {
return role;
}
public void setRole(PlannerRole role) {
this.role = role;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public boolean hasAdminRole(){
return false;
}
Where PlannerRole is enum:
public enum PlannerRole implements IsSerializable {
ADMINISTRATOR,
OPERATOR,
USER;
}

Re: XMLHttpRequest getResponse instead of getResponseText to get arraybuffer data

Hi, I tried to use your solution. Looking at Google I/O on youtube (
http://www.youtube.com/watch?v=NNmoEOpGJdk) I saw this but I wasn't able
to do it.
I tried creating this:
public class BinaryXMLHttpRequest extends XMLHttpRequest
{
public native JavaScriptObject getResponse()
/*-
{
return this.response;
}
-*/;
//Set to arraybuffer or blob for binary response
public native void setResponseType(String value)
/*-
{
this.responseType = value;
}
-*/;
}
then I used this class this way:
BinaryXMLHttpRequest binxhr =
(BinaryXMLHttpRequest)BinaryXMLHttpRequest.create();
binxhr.open(GET, myservlet_url);
binxhr.setResponseType(arraybuffer);
binxhr.setOnReadyStateChange(new ReadyStateChangeHandler()
{
@Override
public void onReadyStateChange(XMLHttpRequest xhr)
{
BinaryXMLHttpRequest binxhr = (BinaryXMLHttpRequest)xhr;
if( binxhr.getReadyState() == XMLHttpRequest.DONE )
{
binxhr.clearOnReadyStateChange();
binxhr.getResponse(); = what can I do with this?
}
}
});
If you look, at the end I have a binxhr.getResponse(); But this function
returna a JavaScriptObject type. What can I do now with this? This is not a
byte[] or whatever, so, I don't know in GWT how to manipulate it. Do you
have an idea?
It will be an ArrayBuffer, so you'd have to build a JSO overlay type
representing ArrayBuffer and cast() the JSO to your ArrayBuffer.
But honestly, it'd be easier to compile GWT from trunk and use the API
that's already in there. When 2.5 will be out the doors, simply replace
your home-built pre-2.5 GWT with the official 2.5.

Re: adding scroll panel to popup panel
It's fairly simple. Do as expected. Put a ScrollPanel inside a popup.
Set the width and height of the ScrollPanel to that of the Popup width and
height. Put something (another panel) in the ScrollPanel and set its width
and height independently.
Here is an example with an HTMLPanel inside ScrollPanel. Done with
uibinder.

public class Tpopscroll implements EntryPoint
{
interface Binder extends UiBinderWidget, Tpopscroll
{
}
private static final Binder binder = GWT.create( Binder.class );

/**
* This is the entry point method.
*/
public void onModuleLoad()
{
binder.createAndBindUi( this );
RootLayoutPanel.get().add( mainPanel );
}
@UiHandler(button)
void onButtonClick( ClickEvent event )
{
ThePopup popup = new ThePopup();
popup.show();
}
}

@UiField HTMLPanel htmlPanel;
interface Binder extends UiBinderWidget, ThePopup

public ThePopup()
{

HTML html = new HTML();
html.setHTML( s );
htmlPanel.add( html );
