Light weight collections
Just curious what the status of the light weight collections is? Currently, when I use a single Anchor element the whole bloody Java collections framework needs to be loaded in my initial fragment so I try to do as much as possible without using the built in Widgets. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Integrating ContentFlow with GWT
I'm looking for a few pointers/tips on how to integrate the ContentFlow Javascript library into my GWT application. For reference and clarification ( I see there are a number of ContentFlow-like libs running around) here, the link to the specific js library I have in mind - http://www.jacksasylum.eu/ContentFlow/index.php. I have read the JSNI documents and understand the basic idea, but my lack of javascript specific knowledge is causing me grief. More specifically, here's what I would like to do: 1) Create a GWT ContentFlow widget that effectively proxies the ContentFlow Javascript object such that I can create 1 or more GWT ContentFlow instances like this: ContentFlow myContentFlow = new ContentFlow(); 2) The Javascript ContentFlow object can take one or more ContentFlowOptions that govern its behavior and funcitonality, thus I'd like to be able to set/get these options with typical getter/ setter methods on my GWT ContentFlow widget like this: ContentFlow myContentFlow = new ContentFlow(); ContentFlowOptions options = myContentFlow.getOptions(); // getter ... modify the options or create new ones myContentFlow.setOptions(options); // setter Note, ContentFlowOptions also appears to be a name/value pair abstraction found in the ContentFlow js library. 3) Create and add 1 or more ContentFlowItem, where an item is a simple abstraction taking an image url, label, and caption myContentFlow.add(new ContentFlowItem(images/image1.png, my- caption1, my-label1); myContentFlow.add(new ContentFlowItem(images/image2.png, my- caption2, my-label2); myContentFlow.add(new ContentFlowItem(images/image3.png, my- caption3, my-label3); ... 4) Register for selection events. When an ContentFlowItem is selected, have it callback to my GWT application with information regarding which item was selected. 5) Set the Style of my GWT ContentFlow abstractions for controlling the widgets look-n-feel. In a nutshell, I'd like to turn the ContentFlow js library of objects/ methods into a full-fledge general purpose GWT widget that can be used for a variety of purposes. Lastly, in the event that someone has already gone thru this work, I'd much appreciate getting access to the resulting work and if not, I'd be happy to share the results of the effort with the rest of the community once I've got a working example.

Re: update widget on panel
I just tried something with interesting results.
In the updateButton anonymous clickhandler class, I tried a
Window.alert attempting to output the index of the widget object w on
its containing panel. It came back -1, meaning w is not to be found.
Does this have something to do with how anonymous inner classes use
the external classes objects? Maybe a clone or something? If so, how
can i handle this?
thanks.

Thanks for all the responses guys. So far it hasn't been so difficult to change the hierarchy of the elements I need. I was mainly just curious as to why such a setup existed - quite an ingenious solution to your problem! Ajax crawling looks very cool indeed but I suspect my site will have too many generated permutations for it to be practical. I'm also running on App Engine and I have read that HttpUnit doesn't like that. I'll keep this thread posted as I take the experiment further in a couple of weeks.

[gwt-contrib] DockLayoutPanel addLayoutCompleteHandler

where any component inside a DockLayoutPanel that depends on the size

{
public void onLayout(Layer layer, double progress)

public void onAnimationComplete()

[gwt-contrib] Multiple inheritance in Widget hierarchy
Hi,
I am reposting this question here as the user list got no reply and I
guess it is more a dev question:
I am experimenting with compiling GWT code with a standard JDK so I
can use the same code to generate HTML on both the client and the
server. So far it seem to be working OK but will only be practical if
I can also get UIBinder and i18n working.
My goal is to create HTML pages that can be crawled and indexed and
also allow GWT code to add, load and modify the page. Others have
recommended building two parallel sites - an html one and a GT one
which seems a bit redundant.
My experiement has put a real w3c Node inside every GWT Node and
replace native methods with ones that manipulate the w3c node. Then
finally I take the full w3c node from any element and convert it into
html.
I found that the object hierarchy needed to be changed to be valid
Java. An example of the issue is with the Anchor widget:
public Anchor() {
setElement(Document.get().createAnchorElement());
setStyleName(gwt-Anchor);
}
com.google.gwt.dom.client.AnchorElement extends
com.google.gwt.dom.client.AnchorElement but setElement expects a
com.google.gwt.user.client.Element so AnchorElement must extend both
classes which is impossible.
I have modified AnchorElement and friends to extends
com.google.gwt.user.client.Element instead which seems to have
worked.
My question is: Is this impossible inheritance hierarchy intentional
to stop this kind of messing about?
Cheers,
John

Re: New layouts not playing nicely with Maps
I had this problem a few months ago
http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/c0dc9b54edd48531
and solved it with a callback which is more reliable than a timer
because it cancels any existing animation which might run past your
timeout.
root.animate(0, new AnimationCallback()
{
public void onLayout(Layer layer, double progress)
{
}
public void onAnimationComplete()
{
map.checkResizeAndCenter();
}
});

I am using UI binding to setup my app, so I needed a little extra
tweak to Eric's code.
If I placed the timer either before or after the createAndBindUi call
in my widget containing the map, I was still experiencing the map UI
rash Jeff and Andrew had.
However, since my app also uses event handling (via gwt-dispatch), I
was able to fire a custom RetrievedMap event at a place in the code
when I know the app has completely finished UI binding (ie, the user
clicks on a nav item to fetch map data, the app retrieves a success
from the server, the app then fires the RetrievedMap event ). My
docker widget containing the MapWidget listens for the RetrievedMap
event, and so I tucked in Eric's timer code to the method handling the
RetrievedMap event and it worked wonderfully.
Phew. What I am trying to say is: if you are using UI binding, a plain
Timer fix may not work because of arbitrary times that your UI may
complete binding. Best to fire an event when you know the UI is
completely loaded, and in handling the event run Eric's timer code.

Hi,
I have the exact same problem as Jeff. One difference between Jeff's
case and Eric's case is that in Jeff's case, the dimensions of the map
are not known; in Eric's case the map is 400px by 500px. It seems this
problem occurs when the dimensions of the map are not known at build-
time.
I want my map to occupy the bottom-right corner of my UI (like Google
Maps). When I use setSize(100%,100%), theMapWidgetis given the
correct size (the Google logo etc appear in the right place) but the
tiles don't cover the whole of the widget.
The trick I used to schedule checkResizeAndCenter() in a timer
callback solved that issue for me
When I provide an explicit
size, or resize the browser, the tiles are displayed correctly.
I don't really want to provide dimensions in pixels if I don't have
to. Is this the only way?
In the past I've always recommended dimensions in pixels for best
results. You could hack around this by hooking into the resize event
listener.
Thanks

Does anyone have the GWT Googlemapsworking inside the new Layout

My page is basically aDockLayoutPanelwhose main element is a
SplitLayoutPanel whose main element is aMapWidget. TheMapWidgetis
set to 100% size.
On startup, the map tiles are sized to a very small part of the area,
although the grey background does seem to cover the entire space:
http://www.infohazard.org/~jeff/mapnolayout.png
If I resize the browser window, the map quickly covers the whole area
and starts to work normally.
I've tried callingMapWidget.checkResize() and the LayoutPanel's
forceLayout() methods but neither have an effect. Any idea what I'm
doing wrong?
The code is super-simple:
Attaching an event handler to existing element
Hi,
I have a page that contains a header div containing some anchors
defined in the html page. My GWT code finds the header with
RootPanel.get(String) and adds it to a DockLayoutPanel. I have tried
to attach click handlers to the links in the header like this:
header = RootPanel.get(header);
NodeListcom.google.gwt.dom.client.Element aes =
header.getElement
().getElementsByTagName(a);
com.google.gwt.dom.client.Element item = aes.getItem(0);
Anchor anchor = Anchor.wrap(item);
anchor.addClickHandler(new ClickHandler()
{
public void onClick(ClickEvent event)
{
Window.alert(hi);
}
});
but get this exception

may not be added to the detach list
at com.google.gwt.user.client.ui.RootPanel.detachOnWindowClose

Can anyone suggest how I should be approaching this situation?

Hello all.

Is it possible to dynamically change the width of the westWidget
somewhere in the associated java code, or can it only by modified in
the *.ui.xml file.
The problem is, I would like to be able to hide/show the westWidget
and have the centerWidget fill the remaining space dynamically when
the app is running,
but changing the width of westWidget in the java code has no effect on
the width of the West Pane of the DockLayoutPanel that was hard-coded
in, there is a disconnect between them.
Any help would be greatly appreciated.

DockLayoutPanel and YUI
Hi, I am using DockLayoutPanel and have found that it seems to be imcompatible with YUI Grids. Specifically, when I include this on my page: link rel=stylesheet type=text/css href=http://yui.yahooapis.com/ 2.8.0r4/build/grids/grids-min.css The page does not layout correctly in IE6. In Safari 4.0 it seems to work fine. The internal layers appear to be offset of the right or not visible at all. This is not a big issue for me as I don't need to use YUI grids now anyway... it was just a left over from using reset-fonts-grids of which I only want the reset and fonts part. Just thought I would mention it. Cheers John. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: DockLayoutPanel and YUI
... and while I am bashing IE6 - I found another issue: When DockLayoutPanel is set to use Unit.EM I found that a child in the east overlapped with the centre child by about 10 px. When I changed to Unit.PX it works OK. Again, in Safari Unit.EM worked fine. Bring on Chrome Frame!

That makes sense. RequiresResize was created for precisely this kind of
scenario, where a widget simply can't work properly without knowing when it

if you fail to call onResize(), but it serves as a hint to the developer
that this is required, and will cause panels that implement ProvidesResize
to automatically call onResize() for their children that require it.

The problem with the map not refreshing properly and having to call
checkResizeAndCenter() immediately after creating it has been around a
long time and there is a FAQ up for it. I hope this works. Having a
way to automatically compensate would take some pain out of creating
maps applications!

Having MapWidget implement RequiresResize would seem to be the right

Does this sound reasonable to you, Eric?

Yeah sorry I was not sure if this was more of a development topic or

I tried your suggestion of map.checkResizeAndCenter() and it works
perfectly. It also seems a better solution than my original
SimplePanel place holder.
It seems that the Google map object initializes its size as soon as it
is added to the document. Perhaps MapWidget could also implement
RequiresResize?
So now a working example is:
public void onModuleLoad()
{
DockLayoutPanel p = new DockLayoutPanel(Unit.PX);
p.addNorth(new HTML(north), 100);
p.addSouth(new HTML(south), 100);
p.addEast(new HTML(east), 100);
p.addWest(new HTML(west), 100);
MapWidget map = new MapWidget(LatLng.newInstance(-41.1,
174.8), 5);
p.add(map);
p.layout();
RootLayoutPanel rp = RootLayoutPanel.get();
rp.add(p);
rp.layout();
map.checkResizeAndCenter();
}

Extending DatePicker
Hi,
I have extended DatePicker so that a date range can be selected on one
widget. The current range is between the last two date selections and
when a date is highlighted all dates between the last selection and
the current highlighted date are emphasized.
It almost works. The problem I am having is that HighligtEvents are
sent twice for every date, mouse-over and mouse-out, EXCEPT when a
date from another month is chosen (i.e. a date in November when the
current month is October). In this case the HighlightEvent for the
mouse-out are missed and the also the event for the highlight of the
current date in the new month is missed.
What would help me is:
1 - if there were a way to know if the HighlightEvent was caused by
mouseover or mouseout (or separate events)
2 - when the month is changed (by clicking on a filler date) the
HighlightEvent should be fired for the new date that the mouse happens
to hover above.
For reference here is my code:
public class RangeDatePicker extends Composite
{
private static final String RANGE_STYLE = range;
private static final String POTENTIAL_STYLE = potential;
private static final long DAY = 1000 * 60 * 60 * 24;
private Date first;
private Date second;
public RangeDatePicker()
{
final DatePicker picker = new DatePicker();
picker.addHighlightHandler(new HighlightHandlerDate()
{
private Date last;
public void onHighlight(HighlightEventDate event)
{
GWT.log(Highlight + event.getHighlighted() +
+
picker.getHighlightedDate(), null);
if (second != null)
{
// normally the same date is fires
twice - for mouse-over and
mouse-out
RangeDate range = new
RangeDate(second, event.getHighlighted
());
if (last != null
last.equals(event.getHighlighted()))
{
// this is a mouse-out so
remove highlights
picker.removeStyleFromDates(POTENTIAL_STYLE, newDateRangeIterable
(range));
}
else
{
// this is a mouse-over so add
the highlights
picker.addStyleToDates(POTENTIAL_STYLE, newDateRangeIterable
(range));
}
last = event.getHighlighted();
}
}
});
picker.addValueChangeHandler(new ValueChangeHandlerDate()
{
public void onValueChange(ValueChangeEventDate event)
{
RangeDate range = getDateRange();
if (range != null)
{
picker.removeStyleFromDates(RANGE_STYLE, newDateRangeIterable
(range));
}
// this will change the date range
addSelectedDate(event.getValue());
range = getDateRange();
if (range != null)
{
picker.removeStyleFromDates(POTENTIAL_STYLE, newDateRangeIterable
(range));
picker.addStyleToDates(RANGE_STYLE,
newDateRangeIterable(range));
}
}
});
initWidget(picker);
}
protected IterableDate newDateRangeIterable(RangeDate range)
{
ArrayListDate iterable = new ArrayListDate();
for (Date d = range.getFrom(); !d.after(range.getTo()); d = new
Date
(d.getTime() + DAY))
{
iterable.add(d);
}
return iterable;
}
protected void addSelectedDate(Date value)
{
first = second;
second = value;
}
public RangeDate getDateRange()
{
if (first != null)
{
return new RangeDate(first, second);
}
else
{
return null;
}
}
}

Re: GWT state management across multiple page/modules.
Hi, I believe what you are after is Code Splitting http://code.google.com/p/google-web-toolkit/wiki/CodeSplitting This is in trunk now and will be included in the upcoming 2.0 release. I am using it in trunk now and it seems very stable. If you're not willing to move to trunk or wait for the 2.0 release you could try using the window name hack where you can store large amounts of data between pages serialized in the window name. John On Oct 2, 11:51 pm, AndrewG andrew.g...@rcrt.co.uk wrote: I tried posing this before - no luck - so I am trying again. I am looking at modifying a (largely) JSF-based web application to use GWT. I have done some preliminary experiments which have been quite successful so far - in providing a richer UI and better user experience. The main issue that I see at the moment is that the current application has approx 100 pages of one sort of another (many are light-weight - but not always simple - 'popup' editor forms for back- end data). The structure of the UI - redesigned for GWT - would be a bit different - making use of being able to dynamically switch page content - rather than using a reasonably big web page hierarchy. Given the number of features to migrate - the final structure and migration path are a bit of a concern. Common sense suggests that it may not be a good idea to try to produce a gwt 'monster app' module containing the whole UI - but instead make it more modular. Current thinking is that the new design should consist of a number of different pages - each containing the equivalent functionality of perhaps 5-10 of the original web pages. A horizontal main menu at the top would allow switching between these pages - each of which would correspond to a different set of app functionality - built into a gwt module. Each gwt 'mini app' module would run on its own web page - so none of these would be too large - and they could be developed one at a time - and integrated into the existing app - replacing the corresponding set of old jsf-based web pages. I have tested this for two of these 'mini-apps' modules - and it works quite nicely. The obvious problem going forward is how to track/manage state in each of these modules when users navigate between them. For example, the 'current' page might contain a series of trees/tables etc - and the user navigates away from the web page hosting that app/ module - and then back again - it will not be in the state that he left it (but in its fresh state). There are obviously a number of different ways to tackle this (from client side cookies to server side backing beans, etc) - but is there a 'proper' way to do it within the context of gwt - ie one that the gwt framework is designed to support easily ? - I suspect that there ought to be - but I have only just started with gwt - so not sure myself. Any informed opinions would be appreciated. thx Andrew --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Hosted Mode very slow on Mac
Hi, I am using gwt trunk with Eclipse on a os x leopard and find that the hosted mode is almost too slow to use. For example, clicking on a StackLayoutPanel header to change panels causes both Firefox and Safari to freeze and the CPU pegs close to 100% for about 10 seconds. Is this unusual or related to the hosted mode UI freezing up due to the -XStartOnFirstThread bug? I haven't profiled it yet to see where the issue is but the fact that it occurs on the stack panel switch shows it is not related to RPC.

[gwt-contrib] Re: DockLayoutPanel and Maps
I have found the issue and am not sure how to fix it using the current
API. After setting 100% height and width on both the DockLayoutPanel
and RootLayoutPanel the map still reported a span of 0 and did not
render correctly. In Safari's Inspector I could see that the only
element without 100% height and width was the generated layout
parent element but after changing this in using the inspector it
worked.
So I think I need to be able to access the Layout.parentElem to modify
its style.

Hi,

with 100% height and width.
public class DockLayoutPanelExample implements EntryPoint {

p.addSouth(new HTML(south), 2);
p.addEast(new HTML(east), 2);
p.addWest(new HTML(west), 2);
p.add(map);
// Note the explicit call to layout(). This is required for the
layout to
// take effect.
p.layout();
// Attach the LayoutPanel to the RootLayoutPanel. The latter will
listen for
// resize events on the window to ensure that its children are
informed of
// possible size changes.
RootLayoutPanel rp = RootLayoutPanel.get();
rp.add(p);
// The RootLayoutPanel also requires that its layout() method be
explicitly
// called for the initial layout to take effect.
rp.layout();
}
}
I believe the map needs to be able to figure out its exact height and
width in pixels.
Can anyone suggest an approach to get around this problem?

[gwt-contrib] Re: DockLayoutPanel and Maps
Actually I think that was a red herring - setting the parentElem style just forced a re-render and changing the map size had the same effect. I think the problem is due to the map trying to initialize itself before layout() is called. If I add a holder panel like this: SimplePanel holder = new SimplePanel(); p.add(holder); and then add the map after layout() like: p.layout(); MapWidget map = new MapWidget(LatLng.newInstance(50, 50), 8); map.setWidth(100%); map.setHeight(100%); holder.add(map); it works. I have one question about threading in the browser - I have used YUI LayoutManager which is very similar to DockLayoutPanel. http://developer.yahoo.com/yui/examples/layout/nested_layout.html If you want to nest layouts or use a map inside a layout you need to register a listener for an onrender event. When I asked why, Dave Glass said that although the JS is single threaded, the DOM elements will not be created by serially so you must wait until the event fires before you can safely layout nested items that depend on the parent layout. Could this be a problem here also? Thanks, John On Sep 28, 7:06 pm, jd jdpatter...@gmail.com wrote: I have found the issue and am not sure how to fix it using the current API.

[gwt-contrib] Re: Async interface black magic
I can see that allowing the above would still not solve the async,
single threaded nature of ajax calls.
But there must be some way to reuse the Service interface on the
client.
Perhaps compiling a call to a Service interface could be implemented
in JavaScript like this:
Java:
StockPrice[] prices = stockPriceSvc.getPrices();
Window.alert(first bit done);
try {
MyResult result = anotherService.doSomehingWithPrices(prices);
Window.alert(all done + result);
}
catch (RemoteException re) {
Window.alert(Oops + re.getMessage());
}
JavaScript:
function firstBit() {
callAsync(stockPrice, secondBit);
}
function secondBit(var prices) {
alert(first bit done);
try {
callAsync(anotherService, thirdBit);
}
catch (e) {
alert(Opps + e.description);
}
}
function thirdBit(var result) {
alert(all done + result);
}
This would give the appearance of multi-threaded code.
I am interested to hear why this would never work in practice ;)
Cheers,

[gwt-contrib] Async interface black magic
Hi,
I am just getting started on GWT and one of the things that strikes me
is the amount of error prone black magic involved in creating an Async
interface. Sure tools can help you keep it in sync with your Service
interface but something seems wrong with it.
This may be naive but I was wondering if something like the new
GWT.runAsync might be useful here? You could completely remove the
need for the Async interface with code like this:
GWT.runAsync(new Runnable()
{
public void run()
{
try
{
StockPrice[] prices = stockPriceSvc.getPrices
(stocks.toArray(new String[0]));
usePrices(prices);
}
catch (RemoteException re)
{
Window.alert(oops);
}
});
The stockPriceSvc would implement StockPriceService rather than
StockPriceServiceAsync. You also would not need the onFailure and
onSuccess
I imagine I am overlooking something!

RPC Serialization Issue - Enumerated Types (GWT 1.5.3)
I recently added an attribute to a class (model) that gets serialized as part of an RPC call. The attribute I added (with setters and getters) is a java.util.List containing my enum type. The List gets put into a Map similar to myMap.put(SomeKey, ListMyEnumType); When I make the RPC call I get serialization errors. I've scoured the net looking for solutions but haven't found any ones that directly address this issue. I think the issue is that the List is nested inside a Map and GWT (at least the 1.5.x branch) doesn't support this correctly. Other than moving to the 1.6.x branch of GWT, which I cannot do right now, does anybody know what is going on and if this is a known issue off of the 1.5.x branch of GWT?
