Can you be a bit more specific - what exactly are you trying to do?

setFocus will move the focus to whatever you choose.

Re: Something other than a Java object was returned from JSNI method

2011-12-31 Thread Ian Bambury

Hi Thomas, thanks for the welcome back!

It appears that there are two issues for me, not one
- the one you kindly gave me the link to (I had actually looked at it,
but didn't get any further than the first entry because the version was so
old)
- and the other is the random history onValueChange with a blank token
followed immediately by it firing with the current token (or what was
current before the blank one was fired). I really can't see where that one
is coming from. I only have one History.newItem call and that has
issueEvent set to false, and I have no timers anywhere (apart from a couple
of scheduleDeferred in order to redraw the screen or allow the
UncaughtExceptionHandler to become active. So what is firing it?

I think I'm going to have to switch to Firefox for development and for
general browsing as the lesser of a number of evils. I've used Chrome as my
main browser since it came out because it was simple and uncluttered and
refreshingly clean, but recent (and not so recent) changes mean it's not as
good as it used to be for me. Just one example, I used to have a list of
recently closed tabs right there on the new tab page, but now I have to use
the 'Recently Closed' menu to get to them. Whose bright idea was that, and
how did it get through any kind of sanity check? 'Look lads, I've got this
great idea, we'll improve the user experience by hiding the closed tabs and
making the user click more times than they used to have to.'

'Great idea, we'll put it in the next release!'

Sigh.

Anyway, Happy New Year to all who read this far :-)

Ian

Re: Cannot install Eclipse GWT (and other Google)-plug-ins

2011-12-30 Thread Ian Bambury

Eventually I got it working by installing the 'Indigo Eclipse IDE for Java
EE Developers' version. All of the other versions I tried gave me the
problem you have, and none of the 'solutions' I found on the web worked
(e.g. install something before something else, uninstall something and
reinstall)

Let us know if it works for you.

 Hi

 I run a VirtualBox on a 64 bit Windows 7, inside this I run a Ubuntu
 10.11 (32-bit).

 The first thing i did when installation completed i ran

 sudo apt-get install openjdk-6-jdk

 And installed this (I have also tried with openjdk-7-jdk).

 Then i installed eclipse (turned out to be the Indigo release) and
 installed also the eclipse-jdts (nothing happened since this module
 was already present and up to date).

 Then i tried installing GWT-plugin from
 http://dl.google.com/eclipse/plugin/3.7
 (and also from .../3.6). I tried installing with a multitude of
 combinations of Google-plug-ins included at the same time. For
 instance Google plugin for eclipse 3.7 and Google web toolkit SDK
 2.4.0 together.

 This gave the following repsonse:

 I then tried to install everything from disc - downloading evertything
 from a manualy downloaded zip-file. This gave the same error.

 Do you kind and cunning people have any suggestions?

Something other than a Java object was returned from JSNI method

2011-12-30 Thread Ian Bambury

I keep getting errors like this (assert errors), seemingly at random.

I haven't done a lot of testing, but it seems to be only in Chrome (latest
version) when running in OOPHM. There are different versions (e.g. go an
int when expecting void etc).

I don't *think* it's me because I can leave the app overnight and get
20-ish of them turn up when all it is doing is sitting there. The line that
throws the assertion error is always the same (or sometimes the assertion
above - here's the trace

There's a comment there
( com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:178))

// Just don't know what do to with this.

What appears to kick it off is an onValueChange event which just turns up
for no reason with a blank token (when there is one there in the address
bar)

I've done a bit of searching but can't find anything helpful or even anyone
else reporting the same problem (apart from back when Chrome was back in
the days of version 10 (I'm on v16.something).

Doesn't seem to happen live or in IE (haven't tried anything else).

Is this a known problem that I've failed to find references to, or does
GWT/Chrome just hate me?

There's nothing very special about my app, it's about three days old and
just logs people in or out and has history support and can page.

Any ideas?

Thanks

Ian

  event handlers are bound when the *widget* is *attached* (i.e. somehow
 its
  onAttach method is called). In short, never use getElement() unless you
 know
  what you're doing (particularly when dealing with DOM tree
 manupulations),
  always use widget methods addWidget() et al.

KeyPressEvent.getCharCode() method has a bug problem in GWT 2.1.0 :

we tried using event.getNativeEvent().getKeyCode() because of the
declared GWT bug at
http://code.google.com/p/google-web-toolkit/issues/detail?id=3753
so we access the native event to get the unprocessed code. Now the
problem:
this code works for FF3 but it doesn't work for Chrome! . in Chrome
event.getNativeEvent().getKeyCode()=10 KeyCodes.KEY_ENTER=13 . in
FF3 the two values are equal (13).

It appears that a fix for KeyPressHandler was completed and reviewed
for this issue on 3/10/2010 (http://code.google.com/p/google-web-
toolkit/source/detail?r=7692), so I was wondering when we could expect
it to be released. The fix appears fairly complex, with different
browser-specific implementations, so implementing a reliable
workaround would appear to be difficult.

Does anyone tried a woraround for this problem? or maybe a GWT
developer could help up get around this issue.

thanks.

Re: Wave

2011-01-09 Thread Ian Bambury

Polite is good, obviously. Asking for help is also, of course, OK. That's
what the forum is about. The problem (I think) Andreas has is people making
wildly general requests (how do I make something like Wave, tell me the
answer) rather than trying to do it for themselves, hitting a block of some
kind, and then asking for specific help with regard to how to approach a
particular coding or design problem within GWT.

Anyone who has been here for a while recognises thinly veiled 'tell me the
answer to my homework' posts - not that I'm saying the OP was doing that,
but it *was* a _very_ general question rather than 'I get this error when I
do something, what do I do to fix it?'

You don't get much more generalised that 'Tell me how to recreate Wave'.
Asked by someone who doesn't seem to realise that the 'i' in GUI actually
stands for 'interface'.

This is a community and i believe the main goal is to share knowledge.
There are a lot people here in the group that spend their time studying
GWT(Thomas Broyer and so on... ) and give those informations for free.
What would it be if they just say Sorry i cant help, go and study the
source code, the solution is there.
If you hav the infos and dont want to give them away that s your choice
and
i m ok with that. But it s alright to ask questions dough
Regards,
Alain

I agree with you Alain. I believe we should try to be a bit more
polite when answering people's questions or trying to encourage
beginners to trace code a little bit before asking questions. Not
everyone is at the same level.

Well, you can do the computational stuff on the server, but there is little
point if all the data is available (or can be made available) on the client.

I think I would go for the term 'obese client' :-)

 Does GWT incorporate a Fat or Thin Client-Server Architecture? Or does

 My view is that it is a form of hybrid as it pushes all of the client

 server.

Re: To GWT or Not to GWT

2010-12-16 Thread Ian Bambury

Hi bkardell,

I think the simple answer is that in extreme cases such as the one you cite,
GWT is not a good fit.

The easiest response is to ask you to give it a bit of time and wait until
you understand what GWT is before you ask these questions :-)

But quickly:

* GWT came into being in order to make JavaScript easier to write by
allowing you to write in Java instead and therefore be able to use all the
tools that are available to Java developers.

* Obviously this means come sort of conversion from the Java-syntax plain
text into a JavaScript script

* In doing so, the Google chaps went a bit beresk in trying to optimise the
code produced. And well done them, they have done a fantastic job at it.

* One of the aims was to produce a monolith that could be uploaded (at a
time-price) initially, but thereafter would be, like a desktop app, already
on the client's machine and only gets re-uploaded if it changes (i.e. an
update)

* Due to the take-up of GWT and the scale of projects people tried to
produce (e.g. a corporate web site in one .js file) code splitting was added
so that not all the code (pages, whatever) was uploaded unless needed.

Basically, though, GWT is aimed at creating a one-page (as in HTML) web
site, not at producing little live-alone gadgets to stick into an existing
page.

I don't think there will, in the near future, be any way to allow tens of
GWT gadgets to access core GWT functionality via a DLL-like common library.
For one thing, my tiny 25kb (currently) gadget, on first use, if it were the
first gadget to be used (and maybe the only one, too) would have to download
a library with code for every single thing that GWT can do, including all
deprecated, outdated and weird widgets. The overhead is pointless.

On the other hand, ten 30k (before compression) widgets is nothing these
days with internet speeds being what they are (and what they will be soon).

So yep, if you have a hundred medium to large sized gadgets that get updated
on a daily basis, GWT is probably not for you unless you write some kind of
gadget-framework in GWT and use some kind of meta-code to control it.

You are very good at coming up with corner cases of a theoretical nature.
May I humbly suggest that you tell us what you are actually trying to do so
that the people in this community can address a concrete problem you have
rather than 'yes but what if...' scenarios.

Specific is good :-)

 Hi Ian,

 as longer I think about your advice, the more I like it. You could do
 interesting things within the resize code, e. g. hide some widgets if

 However, before I give it a new try, I need some additional
 information:

 - If I calculate everything on my own: Which LayoutPanel should I use
 for the parent area (e. g. AbsolutePanel?)?


You don't need a parent panel as such, just position it absolutely after
adding it to the RootPanel.


 - For doing the layout for child objects, I need to determine their
 sizes
  E. g. to center a TextBox, I need its width in pixels. How do I get
 this?


getWidth() ?

but you just need to use 'margin:0 auto'



 - What if I do not know the pixel sizes of child objects?
  E. g. my chess board is a Grid. I don't know its pixel size. How do
 I do this?


How come you don't know its size? Didn't you set it? 16 x each square plus
borders, or just get the width.

Re: 1 layout - 3 browsers - 3 results?

2010-06-08 Thread Ian Bambury

I'm sure someone will correct me if I'm wrong, but layout panels are more
for using the whole of an area of the screen - header, footer, menu on the
left, all the rest used for page display, that kind of thing rather than
allowing you to float things at various places on the screen.

For that, it seems to work OK in my limited experience.

You can use 'margin:0 auto;' to centre the inner panel horizontally, listen
for resize events, and just set 'top' to half of what is left of the height
after you take away the height of the inner panel.

If you don't want to do that (and don't care what happens if the window is
smaller than the inner panel) then you can use 'top:50%;margin:top:-300px;'
(changing '-300px' to half the height of inner panel + border). It's an old
hack, but it still works.

Re: 1 layout - 3 browsers - 3 results?

2010-06-08 Thread Ian Bambury

Yep, a typo

It sets the top to half way down the screen (top:50%) then moves it back up
with the negative margin by half the height of the panel. The effect being
that it is centred vertically.

I think you might need to use 'position:absolute' and set left and
margin-left the same way. It's a long time since I've used it.

Re: 1 layout - 3 browsers - 3 results?

2010-06-08 Thread Ian Bambury


 But what about the differences in the browsers? I thought that GWT
 manages them?


If you add your own CSS, it doesn't go around trying to correct it. It's
just what you do in GWT (using the widgets as they are meant to be used - or
rather, as Google use them and not just how you want to use them, not that
you always get told what that is) and then it's pretty much OK.

So this (http://roughian.com/magnus/) looks wrong in Linux/FF? Shame. It
works in Windows IE/Chrome/FF/Safari/Opera - I don't have the ability right
now to test anything else.

BTW, didn't get the screenshot.

Re: Extending a Widget subclass or Composite?

2010-06-08 Thread Ian Bambury

No.

Ask yourself if you want to expose all the top-level widget's methods. If
you don't, then use a composite. For example, if you are making a labelled
textbox by adding a label and a text box to a VerticalPanel, do you really
want the user able to add more things to the VP, to be able to clear the
widgets out of it etc? If you are making a NumbersOnlyTextBox out of a
textbox, you probably *do* want to expose all the normal methods.

Re: Menubar - retrieving the selected menu item within the Command object?

2010-05-30 Thread Ian Bambury

The way kozura suggested means that you create a new instance with all the
code for every possibility every time (as well as adding extra code for the
switch).

What have you got against creating a command with just the code that that
menu item needs? How does that 'blow up the code in an unnecessary way'?

Kozura's way is like going into a restaurant and, whatever you order, they
prepare and bring you everything that there is on the menu but you are only
allowed to eat what you ordered. All the rest is thrown away (but takes up
space all the time you are there).

HTMLPanel getElementById() - Bug or docs error?

2010-05-05 Thread Ian Bambury

Hi,

In the docs for HTMLPanel getElementById() it says:

Finds an element within this panel by its id.

whereas in practice, the following

HTMLPanel panel = new HTMLPanel(div/div);
Window.alert(panel.getElementById(id)==null ? Not
found:Found);

will alert 'Found' if there is an element with that ID somewhere else in the
document. All getElementById() does is to temporarily attach the panel to
the DOM (if it isn't already attached) and then do

DOM.getElementById(id)

Not what is says on the box.

Re: Dynamic layout using the DockLayoutPanel

2010-04-16 Thread Ian Bambury

You are trying to mix two incompatible concepts:

A DockLayoutPanel added to the RootLayoutPanel will use all available screen
space. No more. No less. Always. It isn't meant to scroll. It's meant to be
the size of the screen.

If you want stuff to scroll in the window, don't use LayoutPanels.

If you want something to scroll within, say, a DockLayoutPanel. add a
scrollpanel to one of the DockLayoutPanel's cells.

Hi all,

For some reasons, the images always have a few pixels between each
other ( apart from IE7 ), and I can't understand why.
To put them on top of each other I use a Vertical Panel.
I also gave each image its own panel, first Horizontal then Vertical,
and set the background to red and yellow to see what is happening

- I cropped the images so I can be sure it's not a transparent
section of the images between them.
- I set the padding of each panel to padding = 0 and margin = 0 to
make sure it wasn't that
- I resized the images so they were rectangular at first then made
them square
- I set the height of the panels, first the main vertical panel, then
the ones inside
- I altered the width of the panels, and the horizontal padding and
margin. The horizontal settings work as expected, it's just the
vertical ones that just don't want to know
- I changed the images, resized them, changed the format from png to
jpg to gif
- I created a stylesheet class with all the paddings and margins = 0,
then applied it to the images, inner panels and outer one.

I can always see the padding between the two images. And yes, it's
annoying :)

Any ideas maybe?

above the URL). Then you'll have to install a plug-in.

 When I create a GWT project in eclipse with gwt2.0.2 and google app

 access the app from (that's fine), but I get NO gwt hosted mode
 console popping up... what am I doing wrong?

 More info:

 Was using GWT 1.6 before this without the eclipse plugin and
 everything was working fine.

 I thought maybe I was doing something wrong, but after looking for
 info as to how it should work, I'm definitely doing the same as the
 following source:
 http://www.ibm.com/developerworks/java/library/j-gaej1/

 Incidentally I thought it might be the fact that Google App engine
 stuff is now there, but if I create a project but I deselect the
 using Google app engine SDK, It still gives me the same problem.

 I have other projects created with GWT 1.6 available in eclipse and
 they work correctly with the new library.
 If I try and create a new -Run Configuration- as a -Java Application-
 instead of the new -Web application- and I copy all the settings from
 the previous projects, I can run that configuration, I get the hosted
 mode, but it gives me the error:

Re: value change listener not firing

2010-04-07 Thread Ian Bambury


 this does not get fired if i simply tab out from the text box. It fires in
 the case when i put some char and delete it and then tab out. is it a bug?


No. If the value has changes then, when it loses focus, the ValueChange
event will fire. If it hasn't changed, then it hasn't changed and so it
won't.

Try the Blur event which fires as the user leaves, whatever.

Adding styles in the ui.xml file using

   - elem.getStyle().setBackgroundColor(blue);

doesn't work if you are using runAsync or LazyPanel

The GWT tools (except for the plugin) are very flexible. So I
recreated my project in eclipse as a java project rather than a GWT
project and then created a java launch to run the application in dev
mode (mainclass =com.google.gwt.dev.DevMode) and another launch to run
the gwt compiler (mainclass=com.google.gwt.dev.Compiler). The GWT docs
detail all of the required parameters, or run them with no params and
they'll output some helptext. Since making these changes I've had no

Re: Change output folder.

2010-04-05 Thread Ian Bambury

What I did is:

- Once in the project:

- Copy all the standard CSS to the /war/ directory - everything at one
level
- Access it via a link in the HTML file (i.e. don't do it in the module
(*.gwt.xml) file
- Change the CSS to get rid of the paths

You now have everything for your project in the /war/ directory that will be
uploaded (apart from the compiled files). This then is how you run it in
development mode

When you want to upload

- take a copy of the /war/ file, then in the copy...
- Move all the generated files to the top level (you can then delete the
subfolder for the generated files in the /war/ directory)
- Change the line in the HTML file from the format

src=output_directory/output_directory.nocache.js
to
src=output_directory.nocache.js

this is what you deploy to the production server. I can send you a working
project if you can't get it going.

There's an old thread entitled SEO issues with GWT webapps - how have
people address this issue?

If you scroll down to an entry by me on 07/07/07 I explain what I did back
then for the Roughian Examples site. That was a long time ago, and I think
there are better ways to approach it, but the site is still quite well
placed. It depends on what you are trying to do what I would recommend now.

Have to disagree with you, Sri.

It is simple to create SEO-friendly content-driven web sites with GWT used
just for navigation and history. There is no need for a recompile if content
changes. I'm working on one like that right now.

If you design it properly, then you don't even need to recompile to add
pages to your GWT-driven menu system and without too much trouble, you can
even have an SE-friendly site with the information held in a database.

Entire website in GWT, yes/no ?

I would say no.

There are two types of websites -

- *Content driven* - which share information. Think blogs, corporate
websites, forums etc. SEO is usually important. And content is almost
always
delivered over http.
- *Interaction driven* - in which the user and site interact closely,
typically involving ajax. Think web apps like gmail, google docs,
facebook.
Here, the content is usually specific to a user, and is typically
delivered
after login. So, you'd want https, and wouldn't care much about SEO.

You can build both kinds of websites with GWT, but it really is suited
for the interactive web-apps. For content-driven websites, GWT is an
overkill. You have to do a lot of extra work to make it SEO friendly.
Modifying content will require a re-build, which gets bugging after a point.
There are ways to get around these limitations, but its just not worth it.

I would recommend you split your website into two parts along the above
lines. For the website portion, use whatever technology you are familiar
with, make it SEO friendly, and deliver it over http. For the interactive
portion, use GWT. That way, you get best of both worlds.

Deleting gwt-servlet.jar

2010-04-03 Thread Ian Bambury

If you delete the gwt-servlet.jar from the WEB-INF/lib directory because you
don't use it, you'll get a warning.

Is there any way (other than ignoring the warning) to stop this behaviour?
The reason I'd like to do this is that I want to zip up a project and
distribute it, but I could do without the 1.5 megs in an otherwise 4k zip
file but I want the project to be clean of errors.

Re: Deleting gwt-servlet.jar

2010-04-03 Thread Ian Bambury

Thanks for thinking about it.

I could resort to putting a dummy, empty jar of the same name in there, but
it would confuse people (me, probably) it it were ever needed later on.

I don't understand why GWT does this. Miguel Méndez said in May last year

We'll relax the WAR (war/WEB-INF/**) constraints in a future release. The
objective for this cycle was to get people up and running quickly and not to
focus on applications which don't have the WAR structure

That was when 1.6 came out and nothing has happened yet...

Re: Annoying Css Loading behavior

2010-04-02 Thread Ian Bambury

Move your CSS file from the /public/ directory to the /war/ directory. You
need to reference it in the module file if you are also using a GWT style.

It's a bug in that it appears that /public/ get copied to the output
directory after they have been picked up by the app hence the 2 reloads
before you see it.

Re: Change output folder.

2010-04-02 Thread Ian Bambury

I haven't tried this but...

What I'd try is:

- Copy all the standard CSS to the /war/ directory - everything at one
level
- Access it via a link in the HTML file.
- Change the CSS to get rid of the paths

When you want to upload

- take a copy of the /war/ file
- Move all the generated files to the top level
- Change the line in the HTML file from the format

src=output_directory/output_directory.nocache.js
to
src=output_directory.nocache.js

Everything is in one directory now and I think that will work. Let me know

Re: Menu Item and MVP

2010-03-31 Thread Ian Bambury

I've been looking into this for a chapter in the new edition of GWT In
Action, here's where I'm at.

The Google I/O approach to MVP has never sat well with me because, apart
from the fact that the interface can get out of hand, it just seems wrong
that the interface specifies that the view must, say, have something
clickable and not leave the implementation to the view.

So what I'm playing about with right now is (for the example you gave).

There would be a couple of interfaces HasClose and HasSave which would be
along the lines of

public interface HasSave
{
void save();
}

There would be a couple of corresponding CloseHandler and SaveHandler
classes e.g.

class SaveHandler implements ClickHandler
{
private HasSave presenter;

public SaveHandler(HasSave presenter)
{
this.presenter = presenter;
}
@Override
public void onClick(ClickEvent event)
{
presenter.save();
}
}

The presenter looks like this
class Presenter implements HasSave, HasClose
{
View view;

public Presenter(View view)
{
   this.view = view;
}
@Override
public void save()
{
view.setText(Save);
}

@Override
public void close()
{
view.setText(Close);
}
}

and the view like this

class View extends FlowPanel implements HasText
{
Label label = new Label();
public View()
{
Presenter presenter = new Presenter(this);
add(new Button(Open, new SaveHandler(presenter)));
add(new Button(Close, new CloseHandler(presenter)));
add(label);
}
@Override
public String getText()
{
return label.getText();
}
@Override
public void setText(String text)
{
label.setText(text);
}
}

in the AppController or onModuleLoad method, you'd just have the line

RootPanel.get().add(new View());

Does that make sense? Feel free to ask but I'm still not too far forward
with this approach yet.

For a tiny project, it's a bit of work (unless you have already written the
interfaces and handler classes for some other project) but it does keep
everything well organised in larger projects.

 I've heard of your approach before, but I'm not clear on the

 or are you passing instances of event handlers? The difference seems

 Let me know what you think. I would assume the first way is what your
 referring to in your comment above, which implies that it is a View

  I've recently migrated from views with many HasXxxHandlers getters to
  views with a setListener method that the presenter injects into its

  It makes unit tests waaay easier to write (you don't have to mock each

Re: Decorator panel outlook problem

2010-03-30 Thread Ian Bambury

It's because the deck part of the tabpanel expands its contents to full
width. Always been annoying, that one.

The decorated panel then stretches and the cells work out their own widths.
This means that the edge cells (decorated bits) stretch to greater than they
should be and you see all the image that you should only see a small part
of.

Two fixes spring to mind:

1) set the width of the decorated panel's content to 1000px minus the two
edge widths - difficult if you use percentages or

2) put the decorated panel in another panel (simplepanel, flowpanel) and put
that in the tabpanel deck

Re: Safari Windows takes 100% on example page

2010-03-29 Thread Ian Bambury

Yep, does the same for me on 4 - I was on 3.x before because I get fed up
with Apple trying to take over my PC every time you load anything - iTunes,
Apple Update and so on - Netscape used to do that and look what happened to
them.

Anyway, I installed 4.something and it does the same for me.

Hi Ian, thanx for your answer.

I'm running Safari for Windows v4.0.5 on Windows XP SP3 (I have the same pb
at home on Vista).

The page loads fine, but the wheel on the right of the address bar keeps
running and CPU goes up to 100%.

Some javascript seems to be looping indefinitely, I can pause it in the
WebInspector.

 a linker, I would think.

 So, is there a reason why you wouldn't want to do it?

Re: Why History.newItem() always calls the onModuleLoad?

2009-12-29 Thread Ian Bambury

a) I could be confusing this with something else (it was a long time ago)
but AFAIK this is due to IE7 replacing mere bookmarks in the HTML with
complete URLs as a security measure (can't remember what this was supposed
to fix but it made sense at the time). Therefore there's very little anyone
can do about it.

b) You can just use a hyperlink (which is preferred way of navigating within
your app and which fires off a history change for you). Anchors are really
for going to another HTML page, not to another state internally (bookmark).

Horses for courses.

 This is bug 1730 reported more than 2 years ago on version 1.4
 (below). Version 1.7 still has it. I feel disappointed that something
 so basic hasn't been resolved. One can not use anchors and class
 History together, unless they don't care about IE users, which still
 the majority.

Re: Can't load the same module twice???

2009-12-29 Thread Ian Bambury

Why would you want to run it twice? What effect are you trying to produce?

Ian

http://examples.roughian.com

2009/12/30 lineman78 linema...@gmail.com

 Can someone please tell me if it is possible to load the same module
 twice.  If so, how?  I have tried including the script tag twice,
 which used to work in older versions of gwt, but no longer works.  I
 was thinking that once it is loaded you could call the onModuleLoad
 function manually, but cannot find how that would work.  Another thing
 I noticed is that if you do include the script tag twice, it writes
 the code to the dom twice, but it is only executed once.  If it is by
 design that you can only run a module once by including the script
 tag, maybe this ought to be prevented.  I also tried using the cross
 site linker, which is what i believe i used before to get this to
 work.

 module
define-linker name=xs
 class=com.google.gwt.core.linker.XSLinker/
 
add-linker name=xs/

Re: Possible bug or maybe I don't understand. Window.alert() and onResponseReceived

2009-12-28 Thread Ian Bambury

You have a method with the Window.alert(anything) in it.

Where do you call that from?

Is that called from the onSuccess method? Or from the sendRequest method?

Need to see the relevant code, really, but I suspect you call it after the
sendRequest and not via the onSuccess().

Re: Page back color

2009-12-28 Thread Ian Bambury

No, you just need to add your CSS file as an entry in the gwt.xml file but
after the inherits name='com.google.gwt.user.theme.standard.Standard' /
line.

That way it gets added after, and it will override the 'standard' file.

Ian

2009/12/27 ALEXEI BARBONI alexeitel...@gmail.com

All right Ian

I just comented the line inherits
name='com.google.gwt.user.theme.standard.Standard' / in my gwt.xml and the
properties of my body in my CSS file are working

But I lost missed all the formats of the page, that, I guess, are in the
inherits name='com.google.gwt.user.theme.standard.Standard' /

I will have to set it all in my CSS file now...

Am I right?

Thanks a lot

2009/12/22 Ian Bambury ianbamb...@gmail.com

Thing is, if you set the style name to MyStyleName then there is no
corresponding .MyStyleName in the GWT styles to override it.

There is a body{} in there though and if you are including your style
sheet from the html file (say with a link) then it will get overridden by
the GWT style sheet which is included (later) from the gwt.xml file.

For example, the standard GWT css file has

background: #ffc;

for the body.

Two things:
1) Are you including your css from the html file?

2) Does your gwt.xml file include a GWT style sheet e.g.inherits
name='com.google.gwt.user.theme.standard.Standard'/ ?

Hi Ian

My CSS file works fine. I mean, every widget that i put setStyleName
takes all properties that are in my CSS file.

I need to know where do I set the properties for the hole page.

Uselly I put inside body { } in my CSS file. But in my GWT project it
does not work...

2009/12/22 Ian Bambury ianbamb...@gmail.com

Do you have some kind of GWT style overriding it?

Have a look in your project gwt.xml file. If you are adding css in the
html host page, the it will be overridden by that.

Ian

And now I see that nothing that is inside my body css (like margin,
font, etc) works...

Where do I set properties for my hole page

thanks

Hi guys, I am trying to change the back color of my page, but I can't
do that..

I tried by CSS

body {
background-color: #f1f2f3;
}

and setting the bgcolor property of the body tag in my HTML file:

body bgcolor=#f1f2f3

/body

It's not working.

Any help?

Thanks again

Re: Can't figure out how to edit a Grid's border

2009-12-28 Thread Ian Bambury

You probably need to set border-collapse:collapse in a css file (or
borderCollapse if doing it in the Java)

Ian

http://examples.roughian.com

2009/12/29 spierce7 spier...@gmail.com

Alright, so I'm not sure how to properly figure out how to do this.
I've been trying to figure out how to do it for a few hours now
without much luck. I've tried playing with some CSS settings, and then
using the grid.setBorderWidth() method, but nothing seems to work.

The space in-between the cells that I'm working with (the best way I
can describe it is the grid of the grid). I'm not 100% which I want,
but I need a way to make that space go completely away, or make it
another color. I can't figure out how to edit that space. I can make
the space bigger with the setBorderWidth() method, but I can't make it
go away. Any help is appreciated. Thanks!

Re: Possible bug or maybe I don't understand. Window.alert() and onResponseReceived

 I have a problem.

 I have a variable on my class:
 public ArrayListHashMapString,String statuses = new
 ArrayListHashMapString,String();
 and I have a method, which populates this variable from JSON.

 So, after populating I try to use it, but it is empty. But, If I use
 Window.alert(something) before, I'll receive in this variable what I
 want.

 For example, this part of code write to GWT.log:

 int statusesSize = statuses.size();
 GWT.log(statusesSize:  + statusesSize, null);
 Window.alert( + statusesSize);
 int statusesSize2 = statuses.size();
 GWT.log(statusesSize2:  + statusesSize2, null);

 12:58:25.541 [INFO] [mythirdgwt2] statusesSize: 0
 12:58:49.864 [INFO] [mythirdgwt2] statusesSize2: 4

 Why it happens? How can I fix it?

Re: GWT 2.0 Panels

2009-12-24 Thread Ian Bambury

Actually, they do try to help, anything with a dash/hyphen in it they flag
up (e.g. 'border-left'). float/cssFloat is it something that catches a lot
of people out (myself included, which is why it sticks in my mind). It isn't
really practicable to include a check for everything.

Everything you do in Java code needs camelCase/DOM-style (e.g. 'borderLeft')

Condiments of the season to you, too :-)

Ian

OK, thanks very much, that helps. I wish that the GWT pages would
 reference the correct css details (an example would do wonders if
 anyone from google listening).

Re: begin with GWT

2009-12-19 Thread Ian Bambury

A GWT application is a web application. So that's easy :-)

Any time you open a new tab in a browser, or a tab in another browser, you
get a new copy of the application. This new copy has no connection with any
other copy that is running (unless you design it, say, to use cookies for
some reason to hold state for the next time the user goes to your site).
Nothing you do in one window will affect what happens in another tab or
browser.

The server just provides services ad hoc to anything that asks for them, you
don't keep state on the server so you don't need sessions, for example. The
server doesn't know or care where the requests for services come from, it
just supplies the data.

If you had a shopping cart, you can keep all the selected items on the
client. If the user wants to delete an item, you do it on the client and
don't bother the server. If the user wants to look at the details of another
product, you get the information from the server. If they decide to buy, you
don't go back to the server, you just add it to the list kept in the client.

If the user has two copies of the site open, adding an item in one tab
doesn't affect the contents of the cart in the other tab. If the user closes
one tab, everything in that cart is lost. Everything in the other cart is
still there. You can alter this behaviour but you would have to actively
code for it.

Hope that makes sense.

i began with gwt and i had a difficulty to understand this expression:
In GWT, all state is purely client-side. A GWT application could be
opened multiple times in multiple browsers, and each window would
essentially have its own instantiation of the application. Hence each
window could be in any state the user wishes, and there is no state
conflict. More, the server need not even be aware of the number of
client windows that are open; each window communicates with largely
stateless server services, and the server is not tasked with tracking
more state due to more interactions with a single client.
what does mean : A GWT application could be opened multiple times in
multiple browsers, and each window would essentially have its own
instantiation of the application
and what is the difference in this point between a GWT application and
a web application

Trevis,

Just to confirm what you are experiencing, the IE Developer Plugin will
only install/work on 32 bit Windows systems. We'll let everyone know when we
have a version that will run on 64 bit systems. Thanks...

I decided to create a new, more descriptive conversation. It seems as
though the IE development plugin does not install properly in 64 bit
vista. Is this issue being addressed? Does. Anyone have a better work
around than remoting into a 32 bit system?

Re: IE Development plugin not working in 64-bit vista.

2009-12-15 Thread Ian Bambury

Have done.

regsvr32.exe oophm.dll did nothing except produce a 'not found' message.

However, searching for the dll and running

regsvr32.exe C:\Users\Ian\AppData\Local\Google\Google Web Toolkit\Developer
Plugin\IE\oophm.dll

seems to have fixed it.

With that setup, I'm not surprised it didn't work before :-)

There are several threads going on in regards to this, which is
exasperating the issue even more. I've created a central issue to track
further information and resolution.

Re: Timer in GWT?

2009-12-14 Thread Ian Bambury

Use the GWT timer


Ian

2009/12/14 Dennis Madsen den...@demaweb.dk

 I'm trying to have a Java Timer in my EntryPoint:

Timer timer = new Timer();
timer.schedule(
new TimerTask() {
public void run() {
//some code
}
}
, 5000);

 But when trying to compile this I got:
 No source code is available for type java.util.Timer; did you forget
 to inherit a required module?
 No source code is available for type java.util.TimerTask; did you
 forget to inherit a required module?

 What to do?
