Alignment in Horizontal Panel

[Dominic Warzok]

Hi 
I want to align some Buttons to the Left in my HorizontalPanel.

This is my examplecode.

 public void onModuleLoad() {
> 
> HorizontalPanel buttonsPanel = new HorizontalPanel();
> 
> Button test1 = new Button("Test1");
> Button Test2 = new Button("Test me ");
> 
> buttonsPanel.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_LEFT);
> buttonsPanel.setWidth("100%");
> buttonsPanel.add(test1);
> buttonsPanel.add(Test2);
> RootPanel.get("buttoncontainer").add(buttonsPanel);
> 
> }


But in this way there is a lot of space between these Buttons. But I want 
them to stick together. Any Suggestions ?

There are at least two (old) issues for it:

http://code.google.com/p/google-web-toolkit/issues/detail?id=2182

In the comments someone mentioned that he has created a library:

Maybe you should try it.

Use of multiple GWT modules in an application

[Denero]

Hi,
I have a GWT application which uses a JavaScript library published on a remote
server and that also was developed under GWT and the APIs exposed over JSNI. I
do not have access to the source ocde of that. That library uses cross-site
scripting and uses xsiframe linker option.

My application which include that in a script node and calls its APIs works fine
in the production mode. But now for some debugging purpose in my application
when I run it in the dev mode, all the API calls to the other GWT library fails
because it looks like it also trying to run in dev mode as I see that
*.devmode.js of that is getting loaded and thus that module is not loaded
successfully(I do not see any errors either).

How can I run my application in dev mode while still keeping the other library
in production mode(ie just like any other native code)? As said, the other
library itself is hosted on a different server and when running our application
in devmode we specify only our module names, so I would expect it to work
bydefault. Is there a compiler or dev mode option that I can use here?

I am using GWT 2.4.0.

Thanks in advance,
dw

Re: Use of multiple GWT modules in an application

[Thomas Broyer]

It's actually (and fortunately) easy: change gwt.codesvr in your URL with 
gwt.codesvr.moduleName, where "moduleName" is your module name (the one in 
your gwt.xml's rename-to="")
That way, the third-party module won't try to run in DevMode, only your 
module that matches "moduleName".

Re: Use of multiple GWT modules in an application

[Thad]

Thomas, indulge my curiosity. I've not the situation that Denero describes, 
but I tried this anyway.

1) When I do this, my app loads *much faster*. Why?
2) Also, I don't see my app's client tab open in the DevMode window. Again, 
why?

Thanks.

Hmm, does it really runs in DevMode then? (e.g., in Chrome is the toolbox 
appearing in the omnibar? or in any browser, is the devmode.js or 
hosted.html loaded? or a .cache.js/html?)

Re: Is GWT market is down?

[Joseph Lust]

I can say from recruitment experience that my office has actively been 
recruiting GWT developers and they are hard to find. Usually we end up 
hiring Java devs with a webapp background and having them learn GWT. I 
would not say there is any trouble finding GWT positions in our US market. 
However we're looking for on-site, not remote developers, so I cannot 
attest to the remote GWT dev market.


Sincerely,
Joseph

Re: Saving results from GWT-RPC call on client

[Joseph Lust]

It really depends how intelligent you want your store to be. For example, 
if a user is perusing a set of N objects, and you hit the server up for 3 
of these objects, you'd want to first check your LocalStorage cache for any 
of those 3 objects (say 2 hits), via a proxy cache, and relay on the RPC's 
for the (1 object) cache misses. This way, after playing around a little 
bit in your app, most requests will be local cache hits and you minimize 
request time and UI latency. Then you also need to limit what's in the 
cache, so you need a LIFO approach like LinkedHashMap. To do this however, 
there is no need to change your GWT-RPC code, but rather make requests to 
you client side caching layer, not directly to the RPC, and let that layer 
make the RPC requests.

That however is an intelligent caching strategy we used for 10K expensive 
objects. I suspect you want a passive GWT-RPC cache which would be most 
readily achieved by exploiting the browser cache with cache headers, but 
consider how you'll expire those objects (TTL?).

Joseph

Re: Are you happy with GWT?

[Joseph Lust]

I've got to add my two cents here since the "pretty" argument and "CSS 
designer" bit has irked me over the years.

There is a clear impedance mismatch between what a CSS/HTML designer can 
kick out from a graphical suite, and what is a truly robust, reusable 
component.

   1. You must protect the CSS namespaces. Just because Mockup A looks 
   good, does not mean it will work well together with Mockup B on Page C.
   2. The CSS in mockups can be quite fragile and verbose, not being well 
   suited to componentization (i.e. depending on x:nth-child(4), x:last-child) 
   when you now have N entries and M instance of the widget on the page.
   3. Various transitions and UI changes in the mockup should be triggered 
   by changing a single class, not manually applying myriad style changes like 
   "right:33px" and "opacity:0.34". Otherwise the devs need to rework the CSS 
   themselves.

Frankly "mockups" can be misleading and make a product look functionally 
complete, even though as coded they cannot be robustly implemented. Such 
things however are not a flaw in GWT, but a need to design for reuse 
and extensiblilty at the mockup stage. So be sure to set some requirements 
for your designers to be GWT friendly and the code should be easy to 
implement.


Sincerely,
Joseph

INHERITANCE FROM JAR FILE , DOESN'T WORK

[Fabio]

Hello

I have an Eclipse GWT CHART project working fine as long as I let my 
library project linked in this GWT project.
But when I compile my library into a jar file, unlink my library 
project from the classpath of GWT project, and add the jar into 
war/web-inf/lib and classpath it

I get the following exception:

[ERROR] [gwt_mwp_sample] - Line 82: No source code is available for type 
sim.fab.gwt.client.util.GTable; did you forget to inherit a required module?

if I rollback everything. WORKS again

why does it happen ?

Yet I put the  into the GWT 
project xml

is it a BUG ?

Thanks in advance

Fabio

GWT Chart which displays bars on x axis at irregular intervals

[Louise Mortimer]

I need to create various charts (using GWT) which will display values along 
the x axis at irregular intervals. 
All examples I have come across (and 
testing I 
have done) display the values along the x axis at regular intervals. 
However for my purposes I need to display a set of values (Y axis) taken at 
specific times/java.util.Date (X axis). 
The range of the x axis can be varied from 1 month to n months *and the 
labels must show the Months*. The values however must be displayed at the 
appropriate place on the x axis (see screen shots). 

Does anyone have any idea how to achieve this using the GWT charts?

Re: problems creating a new Windowbuilder->GWT User Interface

[Robert Blair]

I saw these errors when trying to install the GPE in eclipse 4.2.  I was 
following instructions that indicated you should obtin the plugin in 
eclipse from dl.google.com/eclipse/plugin/3.7

I am no authority, but by guessing that the "3.7" referred to the version 
of eclipse and trying eclipse/plugin/4.2 instead all of these errors 
disappeared.  Good luck!

Re: Use of multiple GWT modules in an application

[Denero]

Sorry, send it too fast.. The application works fine but I realize now that my
gwt module is now not running in devmode. It is not stopping at breakpoints.
Also, I do not see the message "[INFO] [clientsample] - Module clientsample has
been loaded" in the Development mode tab. Just remove .moduleName from the url,
it shows that.

Here is the URL that I tried:
http://127.0.0.1:8882/Sample.html?gwt.codesvr.clientsample=127.0.0.1:9997
where "clientsample" is the rename-to in my gwt.xml file.
Does it look right?

BTW I see that with just
http://127.0.0.1:8882/Sample.html?gwt.codesvr=127.0.0.1:9997,I get the error
message in the development tab for the other GWT module whihc is named "client":
[ERROR] [client] - Unable to find 'client.gwt.xml' on your classpath; could be a
typo, or maybe you forgot to include a classpath entry for source?

Thanks,
dw

What does it mean when gwt-unitCache-... is out of sync exactly??

[Rob]

Hello All,
Can any one tell me in the Eclipse EE environment anyway what does the 
error:
Resource is out of sync with the file system: 
'/MyProject/gwt-unitCache/gwt-unitCache-013A483B3FA8'.
mean exactly?  Does it mean its time for a GWT Compile and isn't it true 
that GWT Compile really only converts portions of Java to Javascript  files 
e.g .js files ??
What do these Cache's get used for and does it effect brower memory usage?
 
Also while I am on that topic How can I measure the browser memory usage 
versus say Virtual Machine vm usage???

Re: gzip compression not working for webkit( Both safari and chrome)

[Youssef Riahi]

Hi, 
Please see underlined info below from  http://www.grc.com/sn/sn-371.txt

Thanks.


*So that's at the connection level as opposed to what you'd call the 
"application level."  The application level, the server, the browser can say, 
independent of the connection, I'm able to decompress using Deflate and Gzip, 
for example.  And then the server says, oh, good.  We're going to save 
bandwidth by compressing those things before we send them to you since you've 
said you know how to decompress them.  So that's at the application level, or 
at the HTTP protocol level.  It's also possible to do compression at a lower 
level, down at the SSL link level, essentially.
So only Chrome and Firefox ever did that.  They no longer do that as a 
consequence of what these guys found.  Also, SPDY used to do that, and SPDY no 
longer does that.  Basically, compression has been, at this level, was 
immediately backed off of.  Now, it's not news that compression can leak 
information, that is, sort of generically.  It's been well understood for many, 
many years that compression and privacy were at odds with each other for 
exactly the reasons I explained last week, which is because the amount of 
compression you get is a direct function of what you're compressing, if the bad 
guys have any control over what is being compressed, that allows them to probe 
for what they don't know, what they don't have control over, which they're 
trying to determine.*

Ah, I see.  It's not in DevMode and though it is running some stuff (from a 
earlier build?) it's incomplete. Thanks.

There are times that GWT reminds me of Clarke's 3rd Law. I love working

Re: What does it mean when gwt-unitCache-... is out of sync exactly??

[Jens]

It caches compilation artifacts (GWT compile and DevMode) so that iterative 
development is faster. 

When Eclipse says that this resource is out of sync with your file system 
it pretty much means that Eclipse has detected changes to these files since 
the last time Eclipse has read-in these files. You can right click the 
folder and select "refresh" from the menu so that Eclipse will re-read the 
files. You normally have to do this when you want to delete the unit cache 
folder within Eclipse to force a full recompile. 

The cache does not affect browser memory usage at all, its just there to 
speed up compilation/DevMode by reusing cached artifacts. To measure 
browser memory usage you have to use tools provided for your OS and/or 
browser. In Google Chrome for example, you can type in "about:memory" to 
see some basic memory stats per browser tab.

Re: what is the function of gwt-unitcache directory (not under target directory)?

I just took a look and it does not look like there is much on this subject. 
It does appear to effect memory in a browser and I recently deleted the out 
of sync entries in eclipse within the gwt-cache folders as specified in the 
eclipse error.log

As to the function I can not say but suffice it to say deleting the out of 
sync entries actually seems to have helped fix an out of  memory error I 
have been getting recently!

the rendered DOM in the IFRAME and add click listeners to some of the 
elements in it.

This works fine sometimes, but, depending on the browser, the DOM in the 
IFRAME appears "ready/finished" at different times.  It would be nice to 
know when the rendering is complete and the DOM ready to have event 
listeners added, but I can't seem to find any aspect of the RichTextArea 
that allows that.  I can override onLoad(), I can add 
InitializationListeners, etc. and I've tried all of that, but it doesn't 
always work.  It seems to be dependent on how long the given browser takes 
to get the DOM ready, but there is no hook to know precisely when that is.

Has anyone been able to figure out how to do this?  It seems like a natural 
feature everyone would want, but I can't find it.

RichTextArea.setHTML() - sometimes parts of HTML are escaped, sometimes not... ??

[TimOnGmail]

Another question - when I call setHTML() on a RichTextArea, with a value 
like this:

HELLO THERE

... most of the time the  is escaped, so the underlying HTML is:

HELLO THERE


SOMETIMES, however, it is rendered exactly as-is, not escaped.  It seems to 
be timing-dependent, because if I put a delay between the attachment of the 
RichTextArea and the call to setHTML(), it rendereds properly, without any 
escaping.

Has anyone seen this?  Any other time-dependent twitchiness like this in 
RichTextArea?

Re: INHERITANCE FROM JAR FILE , DOESN'T WORK

[Abraham Lin]

Does your JAR file contain the source code for your library? The GWT 
compiler needs to have access to the source files, not just the compiled 
class files.

Re: Are you happy with GWT?

[Rob]

Well I have had a differnt story. Given that the books available including 
E-books are scarce and the Javascript generated at times can be agonizingly 
slow when doing calculations and say puting up complex  charts and grids 
with or without a backend RPC servlet. All in  all its ok for what it does 
but there are many gotchas I have seen
For one early on I noted IE 9 did not handle absolute coordinates and well 
and a relative panel approach appears to work  well for positioning widgets.
Also the supply of widgets is a bit scarce as well and Sencha can be 
difficult to use especially given that their samples come with far too much 
overhead and example code. When I want to use a widget sample I want it to 
be plug and chug if you know what I mean. What they prepare is very rigid 
structures.
Also the rpc service calls can be very sluggish? Does anyone know of a a 
way to compress the textual data to/from the servlet??
I should mention that objects exhibit very slow response presumably from 
bulky exchanges of large objects or complex and large objects especially 
ArrayLists

Re: Knowing when DOM is fully rendered after RichTextArea.setHTML() is called?

[Andrei]

Use Scheduler's shceduleDeferred() method. It specifically waits for the 
browser to complete rendering (or whatever else it was doing), and then 
dispatches a new instruction - like to parse the rendered DOM. 

Why do you need to add listeners within the RichTextArea? A better approach 
may be to add a single click handler to the RichTextArea widget itself, and 
check the source of click within this handler.

Re: Knowing when DOM is fully rendered after RichTextArea.setHTML() is called?

[TimOnGmail]

Thanks for the suggestion, Andrei - I'll give that a try!

I'm adding listeners to it because our project requires that users clicking 
on a certain section of text creates a popup for editing that section's 
properties.  We are delimiting these nominal sections like this:

CLICK ON ME

Clicking anywhere on the span or within it brings up the popup.  The popup 
has to know all the metadata, and the value of all the children of the 
.
We don't gate what can be placed within the span - it can be any amount of 
arbitrary HTML.  This means that where they click could be N layers deep 
within a not-necessarily-well-formed HTML structure, so bubbling back up 
the DOM tree to the span we're looking for could be tough, if all we had 
was a screen position on the RichTextEditor.  It might be less hairy than I 
think it is, but I think it would be pretty hairy to do right.
