 Thank you for your comments.

 So you would have one main activity for each major area with one view
 and could have multiple widgets that accomplish what your individual
 activities could?

 I had thought about this, but my concern is by doing so, we lose the
 navigation/history/bookmarking.

 in the case of West Region having West North, West Main and West
 South,
 lets say we place three widgets in the West Region, and treat the
 entire region as a single activity,

 when we click an item in one of the regions (West Main for example),
  selection of an item fires an event on eventBus,
 the widget in West South is listening for this event, and upon
 receiving,
 populates itself with contextual data related to item selected in West
 Main, however
 since we are not using activities and places, the history token doesnt
 get updated,
 and we lose the history which results in poor/broken navigation.

 more over, since we are not using Activities/Places for these sub-
 regions (west_north, west_main, west_south),
 we can not use placeController.go(new place), for communicating
 events, and have to resort to manually creating event handling
 (GwtEvent, etc)

navigation != business event.

If you want navigation, then use places, and in your activitymapper
for the west display region, then return a new activity (with the
same 3 widgets, just different data on them).
Or if you think it could be too resource-consuming (e.g. could lead to
many RPC requests just to show the very same information as before, in
the sub-regions that didn't change) then you could keep a reference on
the current activity (in the activitymapper) and update it with
the new place.

But for side regions, I wonder why you want it to be part of
navigation... when there's a main region, navigation generally is
tied to this region, and the rest is either contextual to the main
region (i.e. determined by the place) or tied by business events
exchanged between the components (or a mix of both).

 What about apps with multiple panels in the same window whose state
 should all be saved together in a single URL? GWT 2.1 does not attempt
 to provide a generic implementation of a composite Place; however,
 your app could create a CompositePlace, CompositeActivity, and
 CompositePlace.Tokenizer classes that delegate to the constituent
 members. In this case, only the composite objects would need to be
 registered with your app's ActivityMapper and PlaceHistoryMapper.

 do you have any idea on CompositePlace , its relation to Composite
 Activity, and how we can map a Composite Place to its corresponding
 Activities ?

Having briefly talked about it with Ray Ryan, the idea is to split the
history token in several parts that you then detokenize as if they
were inidividual places. The CompositePlace would then (to be generic,
adapt to your own needs) model an array of places.
I for one don't buy this idea; I haven't yet met an app where I'm not
doing something or looking at something, and that's the definition
of a place. I'm not looking at something on the left and doing
something totally unrelated on the right (that's what a 'composite
place' would model).

That being said, I'm not working at Google, and I'm not a UX expert;
so please consider that as my very own opinion. Yours might of course
be different.

(and activities and places don't aim at addressing every use case,
only the ones that make 90% or more of web apps)

 in one workspace, WEST_NORTH height could be 100px, while WEST_SOUTH

 with the approach suggested in the article posted above,
 one has to add additional West Regions, to accommodate for the use

Your regions are not required to have a fixed size, you're not
required to use layout panels either. How about using SimplePanel
widgets inside a FlowPanel, without specifying explicit sizes? That
would work too.

In your case though, I'd probably go with either:
 - Ashton's proposal
 - make each workspace it's own GWT app (if they're sufficiently
different to deserve it)

Or:
 - do not use activities (you can still use places if you like)
 - use activities but make your own activity manager (or whatever) to
break the limitations and og beyond what's possible with the stock
implementations; maybe try to use a main activitymanager to switch
between workspaces, and then a set of activitymanager/mapper/regions
within each workspace.

There are many possibilities, and there are no one-size-fits-all.

Re: Help me to get rid of these d... scrollbars!!! :-/

2010-11-30 Thread Jeff Schwartz

Using the developer tools that come with IE allows you to see what the
actual sizes are of each DOM element.

When I need to center an element I apply the following css to its containing
element:

margin-left:auto;
margin-right:auto;

The above will center its content without having to calculate margin sizes.

I center the right panel by setting its margins: I compute the

including margins) is as big as the whole browser window. Could this
be the reason, e. g. when there is a +/-1 inexactness?

Re: Opening a new Window with a Widget in GWT

2010-11-30 Thread Steve Moyer

I've been wondering the same thing ... though it certainly seems like
the accepted practice is to use the PopupPanel and DialogPanel.  In
fact, I can't remember seeing a GWT application that used more than
one browser instance or tab.  In theory, you can style the GWT panels
to look more like separate windows, but the way they're implemented,
you can't drag them off the main window (which can be confusing to a
user).

 Hi all,

 have this problem.

 Question: how to open a new window with a formpanel in side.

 Context: i have an app that lists lots of items, i want someone to
 edit an entry, i want a new window to open so they can edit properties
 then hit save. A standard thing you find in a lot of applications.

 Architecture: I have one client module called UI, it has a dozen
 classes that draw widgets and fill a main area when selected from a
 menu. I have a single html page called UI.html which has the tag in
 the head. Thats it.

 Options Ive Seen

    1.      Call Window.Open() but you need to define a html file. I
 dont have one. I can create an empty one but how do you inject a
 widget in to it ?

    2.      use jsni $wnd to create a new window and get a reference to
 it. But how do i inject a form panel into it ??

    3.      use a popuppanel/dialog panel. They look sucky - plus if
 opening a window through JS is quite simple i would expect it to be in
 gwt.

 Maybe im miss understanding how to use GWT i dont know.

 Any help would be appreciated even if its to correct my application/
 thinking of GWT

If HandlerManager works, you can keep it (as it's still used inside

SimpleEventBus and see what happens (FYI HandlerManager wraps a
SimpleEventBus and adds some behavior specific to handling DOM events,
and I think also some things for backwards compatibility)

Re: .cache.html file size got double after upgrading to GWT 2.1 from 1.7

There's probably something that's not getting pruned by the compiler

Re: GWT 2.1 Activities – nesting? YAGNI ? - an exa mple of where you NEED it !

Another option would be to look at a 3rd party framework. As Thomas pointed
out, the GWT team isn't trying to address every use case, and that's where
pulling in other frameworks can help. There's no shame in recognizing that
you have a complex use case and using any tools available to help. I haven't
tried them, but people often speak favorably about gwt-platform (
http://code.google.com/p/gwt-platform/).

Finally, I want to point out that you may not want to affect the history for
every interaction in sub-views. It's nice for bookmarking, but would make
use of the browser history buttons very frustrating. You may only want to
change the history token when the main subject of the activity (the thing
typically in the center display) changes. You could always provide a feature
to create a reliable link from the current view (like the Google maps Link
feature). That might have the same complexity in terms of implementing your
view state management, but it's still something to consider for usability.

2010-11-30 Thread Ashton Thomas

I think in the case of the composite activity / composite place, you
need to define how closely realted each workspace will be. will there
be any overlap between sub/areas of one workspace and a different
workspace?

You can be careful about how you craft your composite place and how
you tokenize it into sections. one section for each area that holds
the state. then each sub area widget/activty can cache it's current
state and do a really quick check to see if the new section of the
composite place for it's area is different from its current state.

It would probably take a good deal of organizing a pattern and
wrapping your objects in the right way

Re: GWT 2.1 Activities – nesting? YAGNI ? - an exa mple of where you NEED it !

2010-11-30 Thread massimo malvestio

In my opionion if you release a functionality and tell people it's better
if you use it, you have to be aware of impacts this new functionality can
have on existing code.
In my opinion use of DockLayout or TabLayout / Panes is not a rare use case,
think about a mail reader.
MVP approach is very good, and I think that GWT team did a great job about
it, but, given implementation does not consider complex web gui.
What I find inacceptable is documentation, the last paragraph, where GWT
team says:

What about apps with multiple panels in the same window whose state should
all be saved together in a single URL? GWT 2.1 does not attempt to provide a
generic implementation of a composite Place; however, your app could create
a CompositePlace, CompositeActivity, and CompositePlace.Tokenizer classes
that delegate to the constituent members. In this case, only the composite
objects would need to be registered with your app's ActivityMapper and
PlaceHistoryMapper.

In my opinion if you speak about CompositePlace you should describe what you
are talking about, too easy to say yes, you could create a
CompositeActivity, but do it by your own

Anyway, I repeat, GWTeam did a great work about MVP and it's very useful
having directly inside GWT an pattern implementation for organizing classes
about guis, but in my opionion there are a lot of complex gui that
difficultly can be migrated to this approach with actual solution

compiling a GWT app, everything from the public source will copied to
the app output folder (the subfolder in the war folder).
It might not be what you wanted though.

  Or maybe those resources shouldn't be put into that folder to begin
  with (it has always been the case that the module-name folder is
  GWT controlled and always cleared by the GWT compiler before it
  actually generates anything; it might have not always been the case
  for DevMode but I don't see an issue with DevMode doing the same thing
  as the compiler).

 This isn't a GWT compiler issue.  Nothing in this folder is generated
 by the compiler - all that goes to a subdirectory of target/module
 name.  Plus, this didn't happen with previous versions of GPE.  It
 started after upgrading to 1.4.0.

I just faced that very same issue, and a coworker too!
Eclipse 3.6 SR1
GPE 1.4.0
Maven projects using m2eclipse 0.10.2 with m2eclipse WTP integration.
Launching DevMode in -noserver, with src/main/webapp as the war
folder, it clears the whole src/main/webapp folder with the exception
of the WEB-INF/ folder, and it creates a subfolder where it puts the
*.nocache.js, hosted.html and clear.cache.gif.
The exact project layout is:
 - myapp-shared: declares our GWT-RPC interfaces, depends on:
- gwt-servlet(scope=provided) for the RemoteService interface
 - myapp-client: client-only code, depends on:
   - myapp-shared(scope=provided) for the GWT-RPC interfaces
   - myapp-shared:sources(scope=provided) so it has access to the Java
sources
   - gwt-user(scope=provided)
   This is a packagingwar/packaging project, the GWT app is
compiled through gwt-maven-plugin at the prepare-package stage (note
that because of the packaging and m2eclipse, it happens to be a WTP
project, but is not deployed by itself to any server; also, its src/
main/webapp is completely empty)
 - myapp-server: server-only code, implements the GWT-RPC as
RemoteServiceServlet-s, depends on:
   - myapp-shared, for the GWT-RPC interfaces
   - gwt-servlet
   - (several other maven modules)
   This is a packagingjar/packaging project
 - myapp: this is the webapp, with packagewar/packaging, depends
on
   - myapp-client(type=war), will be used automatically as an overlay
by maven-war-plugin
   - myapp-server
   - guice-servlet
   - (several other maven modules)
   This is the WTP app that's being deployed (to a Jetty 7.x instance,
using the Jetty WTP plugin)

I'm launching the myapp-client project as Web Application and
selects myapp/src/main/webapp as the war folder (note, myapp, not
myapp-client; so that the *.nocache.js is created there, I refresh the
folder and WTP automatically publishes the files to the server)

Result: the src/main/webapp/myapp is correctly created with the
*.nocache.js file, but the rest of src/main/webapp is cleared out,
with the exception of src/main/webapp/WEB-INF.
it even messes up with SVN, as an svn update (outside Eclipse, I'm
not using subclipse) doesn't recover the missing files!

  As a last resort, you can still use -noserver...

 As a last resort I can simply copy the resources back into the folder
 after GPE deletes them and before I load the app in my browser.  It
 just seems broken that GPE is deleting whatever it wants from the
 build output directory when starting Jetty.

Re: TabLayoutPanel does not listen to width

2010-11-30 Thread Matt H

Yes, the UI widgets are all terrible. Google Closure has much better
widgets.

On Nov 30, 10:10 am, Baloe nielsba...@gmail.com wrote:
 Hi all,

 I'm using a tabLayoutPanel with three tabs. However, the total width
 is now dynamicly created by the width of the content of the current
 tab. But, my first and second tabs are not that wide, so the third tab
 always hangs a bit outside of the tab. How can I set the width of the
 TabLayoutPanel?

 I tried several things, but I can't seem to set the width.
 tabLayoutPanel.setWidth(700px);
 tabLayoutPanel.setSize(700px, 500px);
 tabLayoutPanel.setPixelSize(700, 500);
 with and without tabLayoutPanel.onResize();

 uibinder file:
         g:FlowPanel
                 g:TabLayoutPanel ui:field=tabLayoutPanel
                         barHeight=50 height=600px
                 /g:TabLayoutPanel
                 g:Button ui:field=buttonAdd text={i18n.save} /
         /g:FlowPanel

 I'm adding the tabs in java code after binding.
         tabGeneral = new FlexTable();
         .
         tabLayoutPanel.add(tabGeneral, i18nGeneral.name());

 I really like GWT a lot, but I must say that the ui pieces are really
 quite bad. You can't use certain widgets because it's standard mode
 (or not) without warnings, setting sizes and other basic stuff doesn't
 always work, examples often work in java code but not in the uibinder,
 etc. It would be nice if the widgets themselves were better. It feels
 like temporary broken, or just beta sourcecode. If you can make such a
 good java2javascript compiler, why not create proper widgets as well?

 Thanks!

Re: Opening a new Window with a Widget in GWT

2010-11-30 Thread John Rellis

I tend to agree, the GWT support for windows is a little contrived.

We have used dialogs to achieve a window-esque approach.

We actually created a couple of applications using SmartGwt that required
heavy utilization of windows, such as popping up move-able charts and forms
to create users etc.

SmartGwt is only suited for large apps IMO though due to its enormous
footprint. It is also all JSNI... not sure how people feel about this.

Maybe check out some widget libraries like http://www.gwtwindowmanager.org/

http://www.gwtwindowmanager.org/Hope this helps!

On Tue, Nov 30, 2010 at 1:15 PM, Steve Moyer smoye...@gmail.com wrote:

I've been wondering the same thing ... though it certainly seems like
the accepted practice is to use the PopupPanel and DialogPanel. In
fact, I can't remember seeing a GWT application that used more than
one browser instance or tab. In theory, you can style the GWT panels
to look more like separate windows, but the way they're implemented,
you can't drag them off the main window (which can be confusing to a
user).

Hi all,

Before you start shooting me down i have checked for answers and i

simple, concise answer. So im asking again for all those that might
have this problem.

Question: how to open a new window with a formpanel in side.

Context: i have an app that lists lots of items, i want someone to
edit an entry, i want a new window to open so they can edit properties
then hit save. A standard thing you find in a lot of applications.

Architecture: I have one client module called UI, it has a dozen
classes that draw widgets and fill a main area when selected from a
menu. I have a single html page called UI.html which has the tag in
the head. Thats it.

Options Ive Seen

1. Call Window.Open() but you need to define a html file. I
dont have one. I can create an empty one but how do you inject a
widget in to it ?

2. use jsni $wnd to create a new window and get a reference to
it. But how do i inject a form panel into it ??

3. use a popuppanel/dialog panel. They look sucky - plus if
opening a window through JS is quite simple i would expect it to be in
gwt.

Maybe im miss understanding how to use GWT i dont know.

Any help would be appreciated even if its to correct my application/
thinking of GWT

Thanks

Is it possible to pass the value @def to the literal function in CssResource

2010-11-30 Thread Marcin Misiewicz

Hi

In my theme I want to use css3 gradients.
Since gradients are not the part of the standard yet I have to use
wrap them in the literal function like in the example (for webkit
browsers) below :
background: literal(-webkit-gradient(linear, left top, left bottom,
from(#FFF), to(#EDEDED)));

It works fine but I would like define in my CssResource variables
gradientColorStart, gradientColorEnd which can be used later in the
other styles definitions. Unfortunately code like below does not
work :

@def gradientColorStart #FFF;
@def gradientColorEnd #EDEDED;

.someClass {
background: literal(-webkit-gradient(linear, left top, left bottom,
from(gradientColorStart), to(gradientColorEnd)));
}

Is there any possibility to use @def inside literal function ?

Re: Large scale application development and MVP tutorial / no Places or Activities

There are two reasons for this, actually:

1. The MVP tutorials were written months before Activities and Places
became available in GWT 2.1.0.
2. The concepts are somewhat orthogonal, that is, Activity != Presenter.

I think some of the reason for the confusion around Activity vs.
Presenter has been that the community has different definitions of
what is a presenter. In the first version of the gwt-presenter
framework (and perhaps Ray Ryan's MVP talk at I/O '09--I'd have to go
back and listen to be sure), a presenter was associated with a place,
and this is the way many continue to think about presenters. Others
take the more narrow view that it's just the biz logic behind a view
or widget and is not tied to the concept of a place at all. In the
latter concept, an Activity might load a view which consists of
multiple sub-views or widgets, each backed by a presenter. Only the
Activity itself is mapped to a Place.

Re: GWT + MySQL

I've used MySQL in just about every GWT app I've written, so it's
quite possible to use it.  Including during development running Jetty.

1: All JDBC calls MUST come from the server.  The client code can NOT
see any jar files, ever.

2: You can NOT reference com.mysql.jdbc.Driver, or any other package
that comes from a jar file, in any class that will end up in the
client.  It doesn't matter if that code is only called from the
server.  Any class that imports anything from a jar file (or from any
of the classes that aren't on the client use whitelist) MUST be in the
server package.

My guess is that you have one or more classes in *.shared that are
importing com.mysql.jdbc.Driver.  Move those classes to *.server, or
move all the MySQL functionality out of them and into classes that are
in *.server.

Re: TabLayoutPanel does not listen to width

So, how do we use the Closure widgets w/ a GWT app.

Because if I wanted to be writing JavaScript, I wouldn't be using
GWT.  No?

  Hi all,

  I'm using a tabLayoutPanel with three tabs. However, the total width

  always hangs a bit outside of the tab. How can I set the width of the
  TabLayoutPanel?

  I tried several things, but I can't seem to set the width.
  tabLayoutPanel.setWidth(700px);
  tabLayoutPanel.setSize(700px, 500px);
  tabLayoutPanel.setPixelSize(700, 500);
  with and without tabLayoutPanel.onResize();

  uibinder file:
          g:FlowPanel
                  g:TabLayoutPanel ui:field=tabLayoutPanel
                          barHeight=50 height=600px
                  /g:TabLayoutPanel
                  g:Button ui:field=buttonAdd text={i18n.save} /

  I'm adding the tabs in java code after binding.
          tabGeneral = new FlexTable();
          .
          tabLayoutPanel.add(tabGeneral, i18nGeneral.name());

  I really like GWT a lot, but I must say that the ui pieces are really
  quite bad. You can't use certain widgets because it's standard mode
  (or not) without warnings, setting sizes and other basic stuff doesn't
  always work, examples often work in java code but not in the uibinder,
  etc. It would be nice if the widgets themselves were better. It feels
  like temporary broken, or just beta sourcecode. If you can make such a
  good java2javascript compiler, why not create proper widgets as well?

Re: GWTTestCase: Unable to access objects returned from a successful RPC call

Stupid question time: Does it work outside of GWTTestCase?

Also, have you tried wrapping option 1 with try ... catch (Throwable
oops) { oops.stringStackTrace (); }?

Greg

On Nov 29, 5:08 pm, jtran jtweez...@gmail.com wrote:
 I've got a project I'm working on where I make an RPC call to the
 server which calls a webservice on a different domain, gets some XML,
 parses it, and then returns to me a Java object.

 Now I'm trying to unit test this and I'm running into a problem where
 my Java object is not accessible after it's been returned by the
 server.  That is, in my onSuccess(MyJavaObject result) method in my
 GWTTestCase, I cannot say: result.getSomeData().  Doing this results
 in something kinda funny...the test just finishes.  It doesn't execute
 any lines of code after that line, and it does not cause the test to
 fail.

 Here's a snippet of my code:

 TestGetSomething.java:
 public void testGetSomeData() {
         MyServiceAsync svc = MyService.Util.getInstance();
         AsyncCallbackMyJavaObject  callback = new
 AsyncCallbackMyJavaObject () {
                 @Override
                 public void onFailure(Throwable caught) {
                         System.out.println(caught.getMessage());
                         finishTest();
                 }
                 @Override
                 public void onSuccess(MyJavaObject result) {
                         assertNotNull(result);
                         System.out.println(result.getSomeData());    // 
 option 1

 System.out.println(Foo);                           // option 2
                         finishTest();
                 }

         };
         svc.getSomeData(parameter, callback);

 }

 Now if I run this as it's written above, Foo does NOT get printed.
 However, if I run this without the line marked option 1, then Foo
 DOES get printed.

 Is this a limitation to the GWTTestCase, or something that I'm
 missing?  Also, something to note, if MyJavaObject happens to be of
 type String, I can say System.out.println(result); and it will print
 the string returned from the server call.

 Thanks,
 Jeff

FlowPanel vs. HorizontalPanel

I have created a FlowPanel that contains 4 ListBoxes and a button.  I
wanted to put some space between the items, so I added empty
HorizontalPanels (with padding: 3px;) as spacers in between each
item.  FlowPanel responded by placing each item (including each of the
HorizontalPanels), on its own line (IOW, it's now acting like a
VerticalPanel).

If I remove some of the spacers, then the items that don't have
spacers between them share a line with each other, and the ones with
spacers each go on a separate line.

Is this a bug?  Is this supposed to happen?  How do I fix it?

While I'm asking, if you resize the panel that a FlowPanel is in, does
it automatically reflow its items?

Thanks.

Re: Opening a new Window with a Widget in GWT

I'd create a separate HTML file that hosts the application module (or a
different module). You can inspect the URL and/or history token as
appropriate to decide what widget to view and any data you may need to
preload it with. The trick then is that I assume you'd want to communicate
events back to the originating window. I'm not sure how to accomplish that,
but I imagine that there's some way to do it.

I think you have to decide if you want the widget to be modal or not. If so,
you'd be better off using a dialog in the application window and there'd be
no need for typical window controls. On the other hand, if it's not modal, a
separate window (that the user can then switch between and close
individually) may be more appropriate.

I tend to agree, the GWT support for windows is a little contrived.

We have used dialogs to achieve a window-esque approach.

We actually created a couple of applications using SmartGwt that required
heavy utilization of windows, such as popping up move-able charts and forms
to create users etc.

SmartGwt is only suited for large apps IMO though due to its enormous
footprint. It is also all JSNI... not sure how people feel about this.

Maybe check out some widget libraries like

2. use jsni $wnd to create a new window and get a reference to

Re: Large scale application development and MVP tutorial / no Places or Activities

2010-11-30 Thread Ray Ryan

I think the community has inferred a linkage between place and presenter
that I never meant to imply. The MVP pattern is a lot more generally useful
than the place notion — it's all about decoupling view and app logic, a
pretty universal concern. IMHO Place is mainly useful for apps that are
about navigating around an object graph, like AdWords and most most simple
CRUD apps, a much narrower set. A concrete example: Wave made great use of
MVP, but never used the place notion because it was too limiting for them.
For details see Dan Danilatos's presentation from I/O 2010, which I never
get tired of flogging:

http://www.google.com/events/io/2010/sessions/gwt-continuous-build-testing.html

The activity and place packages in GWT 2.1 are pretty minimal first stabs,
kind of rushed out the door. One focus of GWT 2.2 will be improving their
flexibility and reducing the boilerplate they require.

On Tue, Nov 30, 2010 at 8:40 AM, David Chandler drfibona...@google.comwrote:

1. The MVP tutorials were written months before Activities and Places

2. The concepts are somewhat orthogonal, that is, Activity != Presenter.

I think some of the reason for the confusion around Activity vs.
Presenter has been that the community has different definitions of
what is a presenter. In the first version of the gwt-presenter
framework (and perhaps Ray Ryan's MVP talk at I/O '09--I'd have to go
back and listen to be sure), a presenter was associated with a place,
and this is the way many continue to think about presenters. Others
take the more narrow view that it's just the biz logic behind a view
or widget and is not tied to the concept of a place at all. In the
latter concept, an Activity might load a view which consists of
multiple sub-views or widgets, each backed by a presenter. Only the
Activity itself is mapped to a Place.

HorizontalPanel and VerticalPanel are implemented as an HTML table. Tables
are block-level elements whereas your form elements are inline elements.
Inserting block-level elements (div, p, etc.) cause exactly what you're
seeing in terms of wrapping, so there isn't any bug there.

That said, you'd probably be better off using CSS to add margins to your
form elements. At any rate, inserting empty tables is a pretty heavy-weight
and unpredictable way of managing layout. Alternately, if you really want
those items to be in a row, just put them inside of a single
HorizontalPanel.


 While I'm asking, if you resize the panel that a FlowPanel is in, does
 it automatically reflow its items?


Yes, items will reflow to the extent possible within the constraints of
any explicit widths that may be set. Note that if you put things in a
HorizontalPanel as I suggested above, that will not reflow since it renders
as an HTML table.

Re: Large scale application development and MVP tutorial / no Places or Activities

The fact that the Activities and Places documentation is under the heading
MVP Framework in the GWT documentation and contains statements like An *
activity* in GWT 2.1 is analogous to a presenter in MVP terminology
(recently discussed in another thread:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/8cd8e6180fc957f8/03eace027a3bd9d4?lnk=gstq=analogous#03eace027a3bd9d4)
doesn't help clear up the confusion. I'd actually say that Thomas Broyer's
blog (http://tbroyer.posterous.com/) is required reading along with the MVP
Framework docs.

I tried GXT 2.2.1 which is for GWT 2.0 (not for GWT 2.1) but I also
tried compiling it with GWT 2.0, which also produce larger script.

Removing old maven repositories in GWT SVN

The GWT SVN repository
http://code.google.com/p/google-web-toolkit/source/browse/#svn/
contains Maven repositories from the 2.1.0 release cycle:

2.1.0.M1
2.1.0.M2
2.1.0.M3
2.1.0.RC1

In order to clean up the root of SVN, these will be deleted from SVN
during the 2.1.1 release cycle.

In addition, the 2.1.0 repo in SVN will be moved underneath a new
maven directory. There is no longer a need for it since 2.1.0 is in
Maven Central, but it can still serve as a backup.

Re: FlowPanel vs. HorizontalPanel

Ah, thanks.

I tried adding padding to my ListBoxes.  That caused the inside of the
box to grow, but did not put any space between the borders of the
adjacent boxes, which is the behavior I want.

I put them in a FlowPanel because I want them to flow, one two or
three items per line, depending on what fits.  Since they're above a
table that the user can grow or shrink, I don't want to manage this by
hand.

 HorizontalPanel and VerticalPanel are implemented as an HTML table. Tables

 Inserting block-level elements (div, p, etc.) cause exactly what you're
 seeing in terms of wrapping, so there isn't any bug there.

 That said, you'd probably be better off using CSS to add margins to your
 form elements. At any rate, inserting empty tables is a pretty heavy-weight
 and unpredictable way of managing layout. Alternately, if you really want
 those items to be in a row, just put them inside of a single
 HorizontalPanel.

  While I'm asking, if you resize the panel that a FlowPanel is in, does
  it automatically reflow its items?

 Yes, items will reflow to the extent possible within the constraints of
 any explicit widths that may be set. Note that if you put things in a
 HorizontalPanel as I suggested above, that will not reflow since it renders
 as an HTML table.

Re: FlowPanel vs. HorizontalPanel

First, let's separate two concepts. You suggested using a custom widget to
bundle two things together. While that may bundle them together from a
source code point of view, that custom widget it ultimately rendered as
HTML. Therefore, HTML ultimately defines the rules for how your content will
be rendered. When composing GWT widgets together to create specific layouts,
it's always good to understand at least superficially what the resulting
HTML will be (e.g., to know when to use InlineLabel instead of Label).

Now, to answer your question... if you have a bunch of inline elements, you
can keep them together by wrapping them in a span styled with
white-space:nowrap;.

If your form elements aren't dynamic and you're using UiBinder, this is
pretty easy to do by wrapping everything in an HTMLPanel (which will
effectively behave like a FlowPanel, except that you can also mix in HTML
with your widgets). If you're doing this all from java, you can still do it,
but you have to use HTMLPanel.add() or HTMLPanel.addAndReplaceElement()
yourself. As far as I know, GWT doesn't provide any container widgets that
render as span elements; all Panel widgets render as divs.

If that doesn't work for you, you can look into using block elements and
float:left;, but that comes with its own complications (and you also don't
get nice text alignment across blocks.

Re: TabLayoutPanel does not listen to width

2010-11-30 Thread Alejandro D. Garin

Hi,

I have made very good layouts using the gwt layout system. I would recommend
to have a look at :

http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html

Regarding to your UiBinder example, don't put the TabLayoutPanel inside a
FlowPanel.

On Tue, Nov 30, 2010 at 7:10 AM, Baloe nielsba...@gmail.com wrote:

Hi all,

I'm using a tabLayoutPanel with three tabs. However, the total width
is now dynamicly created by the width of the content of the current
tab. But, my first and second tabs are not that wide, so the third tab
always hangs a bit outside of the tab. How can I set the width of the
TabLayoutPanel?

I tried several things, but I can't seem to set the width.
tabLayoutPanel.setWidth(700px);
tabLayoutPanel.setSize(700px, 500px);
tabLayoutPanel.setPixelSize(700, 500);
with and without tabLayoutPanel.onResize();

uibinder file:
g:FlowPanel
g:TabLayoutPanel ui:field=tabLayoutPanel
barHeight=50 height=600px
/g:TabLayoutPanel
g:Button ui:field=buttonAdd text={i18n.save} /
/g:FlowPanel

I'm adding the tabs in java code after binding.
tabGeneral = new FlexTable();
.
tabLayoutPanel.add(tabGeneral, i18nGeneral.name());

I really like GWT a lot, but I must say that the ui pieces are really
quite bad. You can't use certain widgets because it's standard mode
(or not) without warnings, setting sizes and other basic stuff doesn't
always work, examples often work in java code but not in the uibinder,
etc. It would be nice if the widgets themselves were better. It feels
like temporary broken, or just beta sourcecode. If you can make such a
good java2javascript compiler, why not create proper widgets as well?

Thanks!

Re: Client File IO

Are you sure the images will overload the server?  Why?

Here's a thought: create an image cache.  You can do it on either the
client or the server.  The client will forget the images if you
click away from it, and the images will only be viewable inside your
client app, but other than that it should work.

If you simply want a proxy server to get around your country's
censorship, go here: http://proxies.xhaus.com/ or here: 
http://www.squid-cache.org/

Good luck

Make TreeItem unselectable

2010-11-30 Thread nathan

Is there a way to make a certain TreeItem unselectable?

For example, given this Tree:

Category 1
- Subcategory A
  - Item
  - Item
- Subcategory B
  - Item
  - Item

How would I make it so that when one of the Subcategory TreeItem is
selected, nothing happens?

I came up with a hacky way that intercepts the SelectionHandler and
checks the selected TreeItem against a list of Subcategory items, if
it's on the list, it doesn't fire any selection events.

Is there an easier way to do this?

Spot on, Brian.

The kinds of changes to Activities and Places we're contemplating for
future versions of GWT are primarily along the lines of using
annotations and generators to automate the creation of PlaceTokenizers
and ActivityMappers, for example. We're not talking about wholesale
replacement, as we strive for API backward compatibility with each
release.

Also, we're thankful for a thriving community of 3rd party frameworks
around GWT and you're always welcome to look outside the box it that
suits your needs better.

MVP without UiBinder

2010-11-30 Thread cri

I'm in the process of trying to learn GWT 2.1 MVP. At this point we
don't have very good knowledge of UiBinder and we're not sure that we
want to learn and use it. I'm having trouble understanding the sample
Hello/Goodbye application (at the GWT docs site) since it relies on
UiBinder. More specifically, I don't know what alternate methods I
need to use that will take the place of UiBinder functionality. Would
someone that understands this stuff summarize what alternative classes/
methods/patterns need to be utilized that would take the place of
UiBinder functionality used in the Hello/Goodbye sample application?
(or in some other way clue me in?). Thanks!

Get a PDF from the Server

2010-11-30 Thread Sean

Hi, I apologize in advance, I am extremely new to HttpServelet and
RequestBuilders, so if this is a dumb question, I apologize. I
typically just work with RPC's, but I don't think this will work in
this case.

I have the user select a bunch of options from the website, then I hit
publish, and it sends the data to the server (using serializable
objects, not Strings) and on the server a PDF is generated, and I want
to return the PDF. I can send the objects, make the PDF, but I can't
return it using RPC's.

After googling a bunch, it seems I should be using a RequestBuilder
with an HttpServlet on the Server side. However, it seems you really
can't send much data with the request, just a single string. Am I
supposed to encode all the data into one string and then decode it on
the other side? That seems like a huge hassle, one I will have to re-
do for every Servlet, compared to RPC's.

For example, I am sending a bunch of SoftballGame objects. Each with
their home team, away Team, time and which team is selected to win. I
don't want to have to encode the team names, as well as the time and
selection into a string, and then do that for all the games.

What's the proper way to attack this?

Re: MVP without UiBinder

I made the switch 3 months after gwt 2.0 release and now, I can't live

2.1.1 AutoBeans + Spring 3 REST implementation

So I've been pounding my head against the wall trying to figure out
what will be a good way to integrate GWT 2.1.1 AutoBeans with Spring
3's REST implementation using RequestBuilder.

There is a lot of really good stuff in the new REST implementation
with Spring 3 but i'm having real trouble getting
RequestBuilder.getText() to return anything other than  when going
through Spring. Was wondering if anyone has had any experience getting
a spring Rest implementation up and running with RequestBuilder.

My googlefoo is failing me on finding an example that works how I
would prefer, which would look something like


RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL);

builder.sendRequest(something,
rb.setCallback(new RequestCallback() {

  @Override
  public void onResponseReceived(Request request, Response
response) {

String text = response.getText();
//Do cool stuff with AutoBean


  }

  @Override
  public void onError(Request request, Throwable exception) {

label.setText(Error:  + 
exception.getMessage());
  }

I can get straight up servlets to return text to my response, but
going through Spring I just get an empty String.

Any help would be greatly appreciated, or maybe I'm doing this
completely wrong and someone can point me in the right direction.

Re: MVP without UiBinder

UiBinder is at least 2-3x faster to develop with once you get the hang
of it (it really isn't hard). Take the time to learn it, your code
will be infinitely more readable, maintainable and manageable.

Re: Get a PDF from the Server

2010-11-30 Thread Chad

Sean,

The way I do it (and this may not be the best way) is to use RPC to
send the user requests to the server. Then, I store the request data
in a table on the server, generating a unique id for that data. The
unique id is returned to the user via the RPC callback. Then, a new
window is opened with the url set to the servlet address and the
unique id as the token in the url. In the servlet, I use that token to
look up the request data, build the PDF, delete the request data, and
return the PDF. This method allows me to send as much data as I want
via RPC and then I only need to send a single parameter with the url
to the servlet.

That's correct.

If you search the list, this has been discussed many times. You'll
probably want to post the raw data to the server, then enable a get the
results button after generating the PDF. But, I don't know the user
requirements.

I've also done the following: establish an invisible frame with a NULL
URL then on a certain state change in the main UI: 1) change that
frame's url to the generated PDF, and 2) make the frame visible.

 After googling a bunch, it seems I should be using a RequestBuilder
 with an HttpServlet on the Server side. However, it seems you really
 can't send much data with the request, just a single string. Am I

That's one solution. The other is to establish a server session,
incrementally accumulate each team's info, then publish it on demand.

 What's the proper way to attack this?

There is no proper way. You just have to be aware that you can't
retrieve a PDF file like you would any other RPC response. If
implementing solutions to that limitation is what you mean by proper
(as opposed to accumulating the team data), then the proper way is to
use a GET to a URL that returns data encoded as an application/pdf
mime type. I prefer a GET to a POST, as my users might want to bookmark
the URL, and I  will not send data that cannot be encoded in the URL.

Re: MVP without UiBinder

2010-11-30 Thread cri

Thanks for the advice and we probably will seriously consider using
UiBinder. However, that said, my problem at the moment is
understanding GWT 2.1 MVP. I'd really like to understand what it takes
to build a minimal application. Since the MVP docs are a little
sparse, the UiBinder stuff is getting in the way of understanding the
MVP. I do at this point understand well the material in the Large
scale application development and MVP tutorials. However, GWT MVP
appears to be very different, at least in regard to the specific
classes used. Again, if anyone can summarize the necessary
alternatives to the UiBinder content in MVP it would be a huge help.
Meanwhile I'll do my best to slog through it. Thanks

Re: MVP without UiBinder

2010-11-30 Thread Stephen Haberman


 gain, if anyone can summarize the necessary alternatives to the
 UiBinder content in MVP it would be a huge help.

You do everything the same, your presenter doesn't change, your
view/display interface doesn't change, you just create and wire your
widgets together manually in your view implementation. E.g.:

class MyView implements MyDisplay {
  private FlowPanel p = new FlowPanel();
  private TextBox a = new TextBox();
  private Textbox b = new TextBox();

  public MyView() {
// do manual layout here
p.add(a);
p.add(b);
  }

  public IsWidget asWidget() { return p; }

  public HasText a() { return a; }

  public HasText b() { return b; }
}

Your presenter then gets the MyDisplay implementation however
it would otherwise with a uibinder impl, pokes at it with the
a() and b() display interface methods, and is none the wiser
that you did/did not use uibinder in the view.

css rendering difference on windows vs linux

We are developing application using GWT2.1 and application will be
deployed on Weblogic 10.3 server.
One of our screen uses DiscloserPanel. Content section has one
Horizontal panel which in turn has 3 flow panels that has borders.
When i run application in dev mode i see expected results. Then i gwt
compiled application and deployed war file to my local Weblogic
instance on windows, I get same results (as expected). But when i
deploy same war file to Linux weblogic server, I see some differences
in rendering (css differences). Flow panel borders should be collapsed
but ther has some spacing etc.. In all instances I am accessing
application from same browser.

What could there be css/rendering differences when same war file is
deployed on 2 diff OS .?
Any help would be greatly appriciated.

Re: MVP without UiBinder

2010-11-30 Thread JosephLi

Hi Jeff,

Is there some special tools u are using to build utilize the UiBinder
way to easily build gui?
I tried it, but I also tried Google's latest offering on the Window's
Builder, which in gives me the impression that it is way more
efficient to build gui with. The tools directly support event click
code navigation right under eclipse, supports css styling directly
with code completion,it event supports reparsing the source to
regenerate the dev view in the tool in case the tool crashed and so
far it worked pretty good.

However when I go the UiBinder way, I got no code completion support,
no event click navigation from the ui.xml file, no wyswug viewer
without deploying the code to see what it looks like. And worst of
all, the assosociated java editor in eclipse all highlighting the
uibinder fields are not found in the ui.xml file. All these makes the
whole thing feel disconnected and not so well tooled compared to the
GWT Windows Builder. So I am wonder if I am missing something when u
say it helps u being productive?


Thanks
Joseph

Re: Get a PDF from the Server

2010-11-30 Thread Sean

Thank you both, I realized that I could do less parameters passed and
just fetch the data from the DB again. I'm very close, but I'm running
into an odd problem. In the Request Builder I pass two arguments like:
 RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,/
servlets/celticlock/print?user=DrunkMcweekNum=12);

When I get to the HttpServelet I am able to do:
String user = p_request.getParameter(user);
int weekNum = Integer.valueOf(p_request.getParameter(weekNum));

However, the doGet method seems to be called twice and the second time
the request is missing those values. Have you guys run into that
problem?

 That's correct.

 If you search the list, this has been discussed many times. You'll
 probably want to post the raw data to the server, then enable a get the
 results button after generating the PDF. But, I don't know the user
 requirements.

 I've also done the following: establish an invisible frame with a NULL
 URL then on a certain state change in the main UI: 1) change that
 frame's url to the generated PDF, and 2) make the frame visible.

  After googling a bunch, it seems I should be using a RequestBuilder

  can't send much data with the request, just a single string. Am I
  supposed to encode all the data into one string and then decode it on
  the other side? That seems like a huge hassle, one I will have to re-
  do for every Servlet, compared to RPC's.

  For example, I am sending a bunch of SoftballGame objects. Each with
  their home team, away Team, time and which team is selected to win. I
  don't want to have to encode the team names, as well as the time and
  selection into a string, and then do that for all the games.

 That's one solution. The other is to establish a server session,
 incrementally accumulate each team's info, then publish it on demand.

  What's the proper way to attack this?

 There is no proper way. You just have to be aware that you can't
 retrieve a PDF file like you would any other RPC response. If
 implementing solutions to that limitation is what you mean by proper
 (as opposed to accumulating the team data), then the proper way is to
 use a GET to a URL that returns data encoded as an application/pdf
 mime type. I prefer a GET to a POST, as my users might want to bookmark
 the URL, and I  will not send data that cannot be encoded in the URL.

No, but I don't do server-side Java. FWIW, this sounds like pilot error. A
few judiciously placed break-points or logging statements will prove me
wrong.

Re: MVP without UiBinder

2010-11-30 Thread Christian Goudreau

no code completion support

If you're using Google plugin ecplise, you have it.

no event click navigation from the ui.xml file

don't know what you mean.

no wyswug viewer

Have you tried GWT designer ?

assosociated java editor in eclipse all highlighting

Shouldn't happen using GPE.

Using UIBinder to write what Stephen wrote:
g:FlowPanel
g:TextBox ui:Field=a /
g:TextBox ui:Field=b /
/g:FlowPanel

The the java file:

@UiField
TextBox a;
@UiField
TextBox b;

@Inject
public AdminGeneralView(final Binder uiBinder) {
initWidget(uiBinder.createAndBindUi(this));
}

Well to me, it feels right. It feels web. Have you ever took a look into
MXML ? XAML ? Well, declarative Ui style is the modern way to write Ui and
with Gwt Designer getting better and better every day, there's no reason to
back off from learning how to use UiBinder.

Cheers,

Hi Jeff,

Is there some special tools u are using to build utilize the UiBinder
way to easily build gui?
I tried it, but I also tried Google's latest offering on the Window's
Builder, which in gives me the impression that it is way more
efficient to build gui with. The tools directly support event click
code navigation right under eclipse, supports css styling directly
with code completion,it event supports reparsing the source to
regenerate the dev view in the tool in case the tool crashed and so
far it worked pretty good.

However when I go the UiBinder way, I got no code completion support,
no event click navigation from the ui.xml file, no wyswug viewer
without deploying the code to see what it looks like. And worst of
all, the assosociated java editor in eclipse all highlighting the
uibinder fields are not found in the ui.xml file. All these makes the
whole thing feel disconnected and not so well tooled compared to the
GWT Windows Builder. So I am wonder if I am missing something when u
say it helps u being productive?

Thanks
Joseph

I made the switch 3 months after gwt 2.0 release and now, I can't live

Re: CellTable with only div's?

2010-11-30 Thread John LaBanca

You could extend CellTable and override the protected renderRowValues()
method to render the Cells using divs.  You can also override CellList, but
CellTable already has the API to add Columns, if you want to use them.
Alternatively, you could override AbstractHasData and just use
CellList/CellTable as examples.

How to prevent CSRF/XSRF when using RequestFactory

2010-11-30 Thread Daniel Cowx

Hi guys,

I've been using GWT-RPC up until this point, but would like to make
the switch to RequestFactory shortly. I'm a bit confused as to how to
prevent CSRF/XSRF with RequestFactory though.

As per 
http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ,
up to this point I've been sending the session ID within the *payload*
of each RPC. Works great. Should I be doing something similar with
RequestFactory? Any and all suggestions greatly welcome!

Thanks,
Daniel

Re: GWT Designer UiBinder can not accept Arabic text.

1) Make sure that you are using the latest GWT Designer 8.1 build

http://code.google.com/webtoolkit/tools/download-gwtdesigner-beta.html

2) Check the ui.xml properties in Eclipse and make sure that the file
is set to use the UTF-8 charset.
