How can I get the Expenses sample up and running?

2011-07-25 Thread Warren Tang
I have trouble to run the Expenses sample in GWT's samples folder. The 
sample appeared in Google I/O sessions a few times. 

I'm not familiar with App Engine, but this is what I've done:

   1. create an new Eclipse project and then overwrite the src and war with 
   those from the Expenses sample.
   2. add App Engine support and specified the application id/name I got by 
   creating a new application in appengine.google.com.
   3. compile LoadExpensesDB.gwt.xml (which I assume is used to fill 
   appengine with some sample data.).The permunations completed but at the 
   beginning of the log their are some errors:
   Compiling module com.google.gwt.sample.expenses.LoadExpensesDB
  Validating newly compiled units

Re: Battery Percentage

2011-07-25 Thread Ashwin Desikan
have two images one for battery red and battery green. you can define 
them as sprites in your CSS under different style names like batteryRed, 
BatteryGreen. Your logic can fire an event when the battery% has reached 
above or below 40% and accordingly change the image by applying the 
appropriate style (Red or green)

Re: Aw: Re: MVP best practices, how to expose a view to a presenter?

2011-07-25 Thread Thomas Broyer
You'd have to either juggle with binding annotations (and possibly private 
modules), or have the same dependencies in your provider as in your provided 
class (to be able to 'new' the class yourself in the provider) and keep them 
in sync.
IMO, unless you're in a hurry, if this is absolutely necessary (i.e. you 
cannot live with either a singleton or the default behavior) then you'd 
better contribute the support for custom scopes to GIN.

Declare an array of panels in UiBinder

2011-07-25 Thread Alexander Orlov
Currently I do

@UiField
VerticalPanel vp;

void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
}

...so, vp contains a variable number of fps at runtime. However I try
to use UiBinder wherever it's possible.

Is it possible to declare Widget Arrays resp. ArrayLists in UiBinder
that might have a different size at runtime and (if not) are there
plans to implement it?

Re: Changed handling of quotes in GWT localizable resources?

2011-07-25 Thread googelybear
Hi,

I am a bit puzzled about this, is no one else facing this issue? How
did you guys solve it?

According to the official Message Format javadoc from Oracle (http://
download.oracle.com/javase/6/docs/api/java/text/MessageFormat.html)
the old trick with doubling the quotes should still work (quote):
Within a String, '' represents a single quote. 

but when I write the following property in my properties file:
foo = you can''t do this

the output will be you can''t do this - with 2 single quotes still
present - instead of one according to the javadoc.

Is this a gwt bug?

thanks for any feedback,
Dennis

Re: Changed handling of quotes in GWT localizable resources?

2011-07-25 Thread googelybear
just found out that this only affects properties loaded via the
Constants interface. When using ui:msg in uibinder files the old
trick still works (I guess this goes via MessageFormat). But when
loading the property programmatically using Constants interface it
does NOT work (meinaing 2 '' in the source file will also be outputted
as 2 '').

Re: Declare an array of panels in UiBinder

2011-07-25 Thread Tomasz Gawel
Assuming you do not use FocusPanel in other cases in this Widget just
anototate addSlot with @UiFactory and return newly created slot from
it:

@UiFactory FocusPanel void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
return fp;
}


this will cause uibinder to call this method instead of FocusPanel's
constructor.

Re: Declare an array of panels in UiBinder

2011-07-25 Thread Tomasz Gawel
Sorry i haven't noticed vp is panel not list ;)
so in java you have sth like that:

ListFocusPanel slots;
@UiField FlowPanel slotTargetPanel;

@UiFactory FocusPanel void addSlot() {
   FocusPanel slot = new FocusPanel();
   slots.add(slot);
   return slot;
}

in ui.xml:

!-- your root ui element --
g:HTMLPanel
div
pSome sample html .../p

g:FlowPanel ui:field=slotTargetPanel
g:FocusPanel/
g:FocusPanel/
g:FocusPanel/
/g:FlowPanel
!-- slots will contain now 3 elements --

g:HTMLSome sample widget/g:HTML
/div
/g:HTMLPanel


in fact slotTargetPanel is not needed for that - you could stick
Focuspanels anywhere in your ui file - as you have an uifactory method
for creatign FlowPanels.

Regarding menu navigation (page to page) in GWT

2011-07-25 Thread Nandha
Hi,
Requirement : More pages . navigation using menu

am using menu for navigating from a page to page..
In this I created a rootpanel with a content panel .
i added  two pages inside the content panel.. one with visible and
another with hidden..
On click of the menu both are interchanging by show() and hide()
functions...
but the sub components are not showing with the proper height and
width
Doubt is : Is the correct way for creating more pages with menu..

or is there any way for creating more pages in a single GWT project
..
Note : In my project there is only one html file and only one
entrypoint

Is there any other way...

Am feeling we can make more html files..
Can anyone help me for that and guide me a way to work with menu for
navigation

Re: How to package a gwt project into a jar so that it can be included into other projects

2011-07-25 Thread Nandha
Hi..

I ll explain upto my knolege

You can use the server side classes directly but not the client..
The server side classes you can find out from
projectname\war\web-inf\classes folder in your workplace of eclipse

Client side Code:
These code are complied as html and java scripts You cannot use it
externally ..
In this you should resuse the client side classes in the editor itself with
the source code by copying your old project package into the new project
packages

Re: Regarding menu navigation (page to page) in GWT

2011-07-25 Thread Justin T
Here's what I usually do to transition between pages in GWT. It may or may
not be what your looking for.

I first clear the Rootpanel, then add to the panel another class which acts
like another page.

Here's a example:

public class Example implements EntryPoint {
  public void onModuleLoad() {
  final Button nextButton = new Button(Go to another page);
  //Activates if the button is clicked.
nextButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
  RootPanel.get().clear();
  RootPanel.get().add((IsWidget) new Page());
}
});
  }
}

public class Page{
public Page(){
//Heres your new page. Anything you add to the RootPanel will show
up on the screen.
   //In your case you will probably want to re-add the menu here first.
 }

}

 On click of the menu both are interchanging by show() and hide()

 but the sub components are not showing with the proper height and
 width
 Doubt is : Is the correct way for creating more pages with menu..

 or is there any way for creating more pages in a single GWT project

 Note : In my project there is only one html file and only one

 Is there any other way...

 Am feeling we can make more html files..
 Can anyone help me for that and guide me a way to work with menu for

Re: Frustrated with GWT

2011-07-25 Thread JC
I spent one week trying to connect my GWT Client application to my
Servlet throug RPC and I got a similar problem.
I gave up testing from Eclipse/GWT plugin against my servlet handling
the JDBC connection. It looks like GWT is forcing you to use Jetty and
GWT database.

I solved the problem with the following solution:
I created a Java package (.jar) to handle all JDBC statements only.
The Servlet invokes the classes in that .jar files.
I deployed the Servlet and the package in Tomcat
I wrote a JSP to test the Servlet. It works great.
I generated a jar file with my GWT Client application which implements
RPC to call the Servlet.
I deployed the GWT Client application in Tomcat.
I tested the whole thing successfully.
You can spent about one hours splitting your application in three
pieces, but it'll work.
After that I'm very happy using GWT just for UI.

I hope this can help you.

Greetings,

JC

Multiple dialog boxes

Hi,
i have a problem with the dialog boxes from the gwt. It is no problem
to use one dialog box,
but i need multiple of them. If one dialog box pops up, the other one
gets locked and you can use the first dialog box until you close the
new one. Is there a way to solve this problem ? For example a
parameter which deactivate this locking feature ?

Cell Table Data Handling Performance

2011-07-25 Thread BST
Hi,

I have successfully managed to use a Cell table  an abstract pager to
fetch the new set of data from an RPC and display them on the cell
table. Many thanks to the developer discussions and Developer Guide.

But I do have a few concerns, as I plan to use it for large data sets,
maybe like 10k objects. The Developer Guide does mention Cell table
can handle large data sets, but I wanna know how large is large, any
approximate number of objects in a list? Also a few other questions
below,


Will my browser performance become sluggish if I load too many objects
simultaneously ? For E.g lets say I store a list of Contact objects,
with a pic of the contact and other textual information such as name,
address and mail. The image might be a blob or a Base64 string.

Is there a performance lag while using the pager on a really large
data set?

If you are not sure, maybe you can tell me this, how the object
handling in a list w.r.t Cell Table is done , and do the objects exist
once objects are converted to html in the Cell Table on the client
Side?

Regards,
BST

SimpleEventBus : why such a non-predictive behavior implementation ?

2011-07-25 Thread david.herv...@gmail.com
Hi,

I'm facing a problem when using the simple implementation of the
EventBus.

// register widget B to be notified when WidgetA trigger an event
register handler of WidgetB on WidgetA.EventType

// dispatch (firingDepth is incremented)
WidgetA.fireEvent

// my widget is really called !!! that's good news
WidgetB.onWidgetAEvent

// on the WidgetA.EventType reception is decided to create a widget C
create widgetC

// this widget register himself to be notified on widgetB events -
here the widget is registered in the deferredDeltas map (enqueueing)
register handler of widgetC on WidgetB.EventType

// widget B fired an event which is never trapped by the widget C
because the handler of Widget C is in the deferredDeltas AND
firingDepth is not 0
WidgetB.fireEvent

I'm doubtful because I was expected Widget C to receive event from
Widget B. A work around is to encapsulate the WidgetB.fireEvent into a
DeferredCommand but it's not really a solution.

An other solution is to reconsider the usage of firingDepth, I don't
really know why it is used (actually I know, but avoid concurrency
modification that way leads to the upper that strange behavior).
In simple implementation (thread safe) will be to get rid of the usage
of this firingDepth/deferredDeltas and that getHandlerList return a
copy of the handlers to go through and that's it:
We insert directly the handler when they request for registration and
we fire on the current map of handlers

Below is a possible implementation of what I think is a better
implementation (behaviorally speaking) :

Re: GWT MAVEN PLUGIN Loading Images

In a Maven project, images and other Web artifacts (html, css) belong
under src/main/webapp. If you're using GWT's image bundling (see
ClientBundle in docs), the images will go in src/main/resources
instead.

Please post any follow-up questions specific to gwt-maven-plugin to

RequestFactory create proxy object serverside

RequestFactory that this object has not been persisted jet and force it to 
send the whole object, not just the diff? Just as if it had been created 
using requestContext.create(FooProxy.class) .

SharePoint Permissions Issue - Users moved from Domain A to Domain B

2011-07-25 Thread Srilakshmi Chilukuri
We have an Windows Server 2003 AD DS forest, under which we have two
domains trusted
Domain A and Domain B

We are moving users from Domain A to Domain B

We have  MOSS 2007 intranet and internet SharePoint site which have
several site collections with sites ranging from 10-500 in each site
collection.
Till now the users were given permissions using DomainA\userid to all
these sites.

After the users are moved to the new domain, I have to give
permissions to the individual users once again by adding them to the
sites using  the DomainB\userid account.
We have 5000+ users what is the best way to replace or change the
users permissions to use the  DomainB\Userid accounts.

Are there any tools available for doing this?

Re: Cell Table Data Handling Performance

2011-07-25 Thread John LaBanca
On Mon, Jul 25, 2011 at 6:49 AM, BST babusri...@gmail.com wrote:

 Hi,

 I have successfully managed to use a Cell table  an abstract pager to
 fetch the new set of data from an RPC and display them on the cell
 table. Many thanks to the developer discussions and Developer Guide.

 But I do have a few concerns, as I plan to use it for large data sets,
 maybe like 10k objects. The Developer Guide does mention Cell table
 can handle large data sets, but I wanna know how large is large, any
 approximate number of objects in a list? Also a few other questions
 below,

The maximum page size is heavily dependent on the app and the data being
displayed, but some teams have gotten into the 250-500 rows per page.
 Assuming your backend can provide the data quickly, the limiting
performance factor of CellTable is rendering, and rendering a 500 row table
isn't instantaneous.



 Will my browser performance become sluggish if I load too many objects
 simultaneously ? For E.g lets say I store a list of Contact objects,
 with a pic of the contact and other textual information such as name,
 address and mail. The image might be a blob or a Base64 string.

All modern browsers should be able to handle an array of a few thousand
Contact objects without a problem, but if you are searching through the
array, that might be slow.  You also have to consider bandwidth constraints.
 Can you load the Contacts on demand and push the processing to the server?


 Is there a performance lag while using the pager on a really large
 data set?

There is no performance lag in CellTable itself.  If your backend can
provide data within a range, paging is a better experience than loading
10,000 objects upfront.


 If you are not sure, maybe you can tell me this, how the object
 handling in a list w.r.t Cell Table is done , and do the objects exist
 once objects are converted to html in the Cell Table on the client
 Side?

CellTable caches the row values within the current page so it can pass the
row values to Cells, and so it can re-render rows when needed.  When you
switch pages, the row values of the previous page are dumped.



 Regards,
 BST

recommend smartgwt.  Something that is going to get a lot of traffic and

Re: Cell Table Data Handling Performance

2011-07-25 Thread BST

Many Thanks for the input. 

The scenario is that I am not displaying more than 100 rows per page. And 
the pager works through 3 pages. 

Yes the Data load is on Demand, as when the user presses the next button for 
the 4th page I am getting another 300 rows thru an RPC. It is a plain view 
only table. So only after the user has paged thru the 3 pages I go for the 
next batch of 300.

 Also No changes or search within the table, it is view only. The table is a 
result of a server call for search. So I guess so far no worries :-)


CellTable caches the row values within the current page so it can pass the 
 row values to Cells, and so it can re-render rows when needed.  When you 
 switch pages, the row values of the previous page are dumped.


My understanding: So when I am viewing the 11 th page with 100 rows and go 
to the 12th page  (using an implementation AbstractPager), the rows on the 
11th Page is dumped and no longer in the browser. So only 100 rows are 
managed by the browser even though 1100 rows of data is available with the 
DataProvider List. Have I got it right?

Let's say the User has paged thru about 12 pages, so there is a list of 1200 
in the dataProvider list already of which 100 are being shown in a page. So 
when the user goes back and forth within the range of 12 pages(1200 rows) 
sorting or changing the display per page  to be 50 or 25 (on the client 
side),will the cell table efficiently manage? 

I guess after your reply I will be more confident in delivering the solution 
:-)

Yes, it only caches the data on the current page.  When you go back and
forth between pages (even pages that you've already visited), CellTable will
send a new request to the data store for the rows in range.

This allows you to control the overall caching policy in your data provider.
 You can choose to cache all rows that you receive from the server in your
data provider, or you could, for example, just cache a window for plus or
minus 5 pages.

Re: GWT + Javascript Libraries

2011-07-25 Thread KD
It totally makes sense to use other libraries (with JSNI approach) to
do something that GWT does not offer out of the box (yet i.e.)
The problem is making a wrapper that is agnostic to the JS library
version and making sure you are not writing your own (pure or not)
javascript that is not cross-browser OK.

 mix GWT with other Javascript libraries (eg.http://makeawesomeweb.com/?cat=13)

 I wonder if there are any groups or other resources for developers that want
 to develop in both GWT and JS.  While I love GWT, I really want to take
 advantage of some of the amazing JS libraries that are out there.  I know
 there are various ways to integrate and expose API points (GWT - JS, or
 visaversa), but I am yet to see any great resources from people doing this
 in practice (I have read the GWT doc pages, and seen some GWT libraries that
 make exposing GWT API to native JS easier).

 Why don't I jump to pure JS?  I really like the ability to develop my core
 logic code in Java.  

 Any pointers to resources on people combining JS + GWT would be very much
 appreciated as are experiences and opinions (you're mad, I do it all the

Google beta plugin 2.4

2011-07-25 Thread bbgott
The website for the Google beta plugin lists an install repository for
Eclipse 3.7 (Indigo).  When I attempt to install the plugin from that
repository, I get an error message indicating that the repository does
not exist.  Will the Beta plugin for Eclipse 3.6 work, or should I
wait for the repository to be fixed?

URGENT: navigation bar menu

2011-07-25 Thread Marko
Hey guys.

I need one menu where user doesnt need to click to see the menu items.
I didnt find anything for it, so I tried with MenuButtons and insert a
Menu with items in it, and then add two events: MouseMove and
MouseOut.

But it doesnt work well and I think its because of the animation
coding for Menu, like: menu.animateShow(AnimationEffect.FADE);

Can anybody help me please!

thnx,
Marko

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

2011-07-25 Thread Eric Ridge
So I just found the page on developer.apple.com that definitively says
the WebKit plugin API is no longer supported as of 10.7 (which I
assume also means Safari 5.1, regardless of OS version):

http://developer.apple.com/library/mac/#documentation/InternetWeb/Conceptual/WebKit_PluginProgTopic/WebKitPluginTopics.html

It says:

Note: As of Mac OS X v10.7, the legacy WebKit plug-in architecture is
no longer supported. Going forward, you must convert WebKit plug-ins
to Netscape-style plug-ins or Safari Extensions.

So now that I know what's going on for sure (and have documentation
reference), I'm going to attempt to convert the plugin.  Wish me luck.

 I don't think that's the case per se.  The Plugin API still exists
 within the WebKit.framework.  I saw some rumblings on the 'net about
 the API being deprecated, but couldn't find anything definitive on
 Apple's developer website.

 I'm no Cocoa expert, so there's probably a thousand reasons why I
 failed, but I couldn't even get the WebKitPluginStarter example from
 developer.apple.com to work.  Looks like it was created long ago, so
 maybe it's bit-rotted.  Safari did load it (unlike the GWT plugin),
 but it didn't actually work.

 I really wish somebody from the GWT development team would see this
 thread (and issue #6601
 http://code.google.com/p/google-web-toolkit/issues/detail?id=6601) and
 reply.

 Lion  Safari 5.1 are definitely brand new, but I find it hard to
 believe that nobody on the GWT team was involved with the developer
 previews of Lion.

After using Context menu, how to trigger the browsers default one? (on, say, an image)

2011-07-25 Thread darkflame
I was using this bit of code I found to detect a right click action on
a widget;


@Override
 public void onContextMenu(ContextMenuEvent event) {
 event.stopPropagation(); //This will stop the event from being
propagated to parent elements.
 event.preventDefault(); // because cancelBubble(Boolean) is
deprecated
 Window.alert(“replace this line with your popup function “);
 }

The widget implementing ContextMenuHandler.
This works, only I'd like to only trigger it sometimes, and at others
leave the browsers normal context menu to appear.
I thought this would be as easy as putting the whole thing in a IF
statement;

@Override
public void onContextMenu(ContextMenuEvent event) {

Log.info(context menu event triggered);

//override the menu only in edit mode
if (panelstreamer.EDITMODE){
 event.stopPropagation(); //This will stop the event from being
propagated to parent elements.
 event.preventDefault(); // because cancelBubble(Boolean) is
deprecated
 Window.alert(replace this line with your popup function );

} else {
Log.info(_context menu event triggered but no 
edit mode);
}
}

But this doesnt actualy seem to work - the second Log file displays,
but the normal right click context menu still doesnt pop up.

Do I have to specificly tell the browser too?
(even though the stopPropation and preventDefault arnt being
triggered).


Thanks for any help,
Thomas

Re: Making the Slider Bar included in the Google Web Toolkit Incubator Vertical

This would be very nice, but I think impossible with the current

You could try this one;

Good luck, Eric :-) It likely requires non-trivial changes (which is

Re: RequestFactory create proxy object serverside

2011-07-25 Thread Ryan McFall
I don't think this will work, nor do I think it should.  As far as I
understand it, when you send a proxy reference via a Request, the RF
framework attempts to find the server-side entity the proxy is
referencing (using the ID), and then calls the associated method in
your service implementation passing the server-side entity to the
requested method.  Since your object does not exist on the server if
looked up by ID, the call should fail.

If you want this to work, you need to actually persist the object in
createByBarId.

Why do you want to do this?  I've wanted to do it in order to get
default values set on the client-side proxy, but not have the object
persisted.  Unfortunately that's not possible.

 I think I understand the reason for this error. But is there any way to tell

 Safari changes going forward. The FF change is especially onerous as
 it now requires engineering effort every 6 weeks to stay up to date.

Re: GWT Developer Plugin on Safari 5.1 (OS X Lion 10.7) doesn't load

The former.

I was looking around in the repository, but didn't see it (them). But I
have to admit I didn't spend more than 5 minutes searching.

Anyway, the maintenance of the FF plugins has exigent nature that isn't
shared by most of the GWT baseline. Can the relaxed nature of most
Open Source development work with such a time-constraint? That's why I'm
suggesting a discussion about this topic.

spurious blur event after update to 2.3

2011-07-25 Thread bhomass
I used the CellEditor.startEdit() feature on a tab header. after
upgrade to GWT 2.3, I am getting unexplained blur events which
continuous stops editing. for example, right after I start edit mode
(by double clicking the header), there is a blur event. I used the
code to ignore that. then after every key stroke, another blur event,
there are others whose origin is not at all clear.

Any one knows what could be causing this and how to prevent it?

Re: GWT frameworks?

2011-07-25 Thread Tomasz Gawel
still nobody mentioned gwt-query - which btw is truely a framework.
while i dont like it's jquery-like naming convention - i stay
impressed with the code itself, especially selector engine ;).
as to gxt and smart gwt - it was not sth i was looking for so i
abandoned using it.

gwt itself is a framework - and while i am not fully convinced to it's
swing-like widget/panel architecture (and gxt or smart gwt made it
even worse), i got used to it.
what i found really missing in gwt was selector engine. moreover, it's
fast growing framework, and thus leaving less area for frameworks.

pure javascript frameworks in much level originated from a necessity
to cover browser differences, and its it's not the case with gwt.

 The speed of compilation and the starting in the dev server is indeed a
 little slow, but then again if you look at what it is doing...

 Take Java code and transform that into javascript and html, then rinse and
 repeat 6 times for all supported browsers and versions. Then repeat that n
 times once for each language specified. In the end that means that where you
 compile your java project once you compile your gwt bit at least six times
 yet it only takes 3 times as long...
 One thing I did to speed things up is remove all languages other then
 default this saves a lot of compilation steps and reduces the time it takes
 to compile significantly. After all once you have confirmed that a string is
 translated there is little point in doing that again for every debug round.

 Another easy thing to do is reduce the compilation amount, do you really
 need to recompile every single time? Most of the changes in your code can be
 tested without having to recompile just redeploy the solution and all client
 side code will/should (it does sometimes fail) run in the new updated
 version.
 Also pretty much all professional outfits use a nightly build to put the
 whole lot together, build and deploy it all beyond that most of the time
 developers work on their own portion of the code which they can compile and
 test without always needing to compile the full project.

 Then there is one other thing which I know won't sound nice but it is
 true. A gut feeling of 1 minute or even several minutes usually turns out to
 be way less then that. Just like with performance testing you cannot trust
 your feelings you have to measure things before you can say for sure. For
 instance it has been found that one can make an application a lot faster by
 showing the user a progress bar and status messages about what the program
 is doing. The program is no faster but the user has the feeling stuff is
 happening thus they feel that things are going faster even though there is
 no factual difference in the execution speed.
 So never trust a feeling, at least not when it comes to the measuring of
 idle time waiting for a computer, as it is very often quite far of from
 reality.

 Regards,

 Rob

Re: How can I get the Expenses sample up and running?

Hi David,

I'm really thankful for your patience for answering this starter's 
question. 

I imported the project into eclipse from according to the readme file. Maven 
had an issue finding the gwt-servlet2.2.jar. I fixed it by changing the GWT 
version to 2.3.0 in pom.xml, and adding GWT SDK and Appengine SDK to the 
classpath. The project was then built successfully. But when I run it in the 
dev mode, the following error appears in eclipse's console view:

I've no idea what it means. 

Besides, it should need my appengine credentials in order to fill data into 
appengine, right? How can I configure it?

Re: Eclipse Analyzing Sources Slow

2011-07-25 Thread gutto
Over the weekend my build times have reduced! Perhaps we were having
some network issues which were exacerbating the problem. However, it's
still slow. I have tracked the cause down to repeated requests for the
DTD document http://dl.google.com/gwt/DTD/xhtml.ent that is referenced
by each UI Binder templates. I have 80 XML template files and the DTD
doc is request 178 times during a clean build. The workaround I have
found is to download and store this document locally and add it to the
Eclipse XML Catalog. Doing this reduces my build time from approx. two
minutes to under 15 seconds.

Wouldn't it be sufficient to fetch such things once per build?

Would be interesting to know if the previous GPE and Helios request
this DTD so many times. (I used Wireshark to watch what was going on.)

2011-07-25 Thread John LaBanca
The primary reason is that we didn't want to impose the restriction that all
table based implementations of HasDataPresenter contain a header and a
footer consisting of a single header/footer per column.  You can imagine a
variation of CellTable that does not include headers, or one that supports
multi-line headers.  To be honest though, we (I) may have walked into a
over-design hole.  Technically the header/footer is part of the view, but it
probably would have been fine to just include it in the Column.

We had to home-bake a CellTable equivalent that has a header with multiple
rows and cells that span multiple columns

Just my 2c.

 The primary reason is that we didn't want to impose the restriction that
 all table based implementations of HasDataPresenter contain a header and a
 footer consisting of a single header/footer per column.  You can imagine a
 variation of CellTable that does not include headers, or one that supports
 multi-line headers.  To be honest though, we (I) may have walked into a
 over-design hole.  Technically the header/footer is part of the view, but it
 probably would have been fine to just include it in the Column.

 I had about an hour-hour and a half to play with this over the weekend and
 I have to say it looks great. I have to ask though, is there a reason why
 ColumnT,? doesn't contain the header and footer cell? It would sure make
 it easier for things like reordering columns, hiding columns. Also it seems
 like the header/footer are a kind of metadata for the column itself.
 Admittedly, there is nothing stopping me from doing this on my own, but it
 seems to me like the header and footer belong to the column itself. What
 edge case haven't I considered?

[gwt-contrib] Adding API method Column#setDefaultSortOrder(boolean isAscending) to control whether the column ... (issue1498806)

2011-07-25 Thread jlabanca

Reviewers: pengzhuang_google.com,

Description:
Adding API method Column#setDefaultSortOrder(boolean isAscending) to
control whether the column should be sorted in ascending or descending
order the first time it is clicked.  Currently, the first time a column
is clicked, it is sorted in ascending order.

Thanks, this is nice. Would you mind expanding the patch to make some
existing event types use it? How about the set in
com.google.gwt.event.logical.shared?
