Re: Drag and Drop UI using GWT with Connectors

[Santosh]

Sorry for the late reply. Thanks for your inputs. Unfortunately, we do
not have the privilege to use HTML5 and CSS3. As we may also have to
support IE8...

@Rob: I have looked into few of those sites. Mostly it is about
integrating drawing tools into our application.  I am not sure, how we
can use it in our applilcation.
First, can we integrate them along with GWT. Second, programmatically
draw the diagrams, give a Drag and Drop feature for the diagram,
handle connectors..etc.
It would be really great if we have suggestion with this design.

Now, I have looked into lib-gwt-svg API. But, using which we can draw
diagrams. But still, not enough documentation on how to make use of
api. If anybody has any resources or links which they can share would
be great.

Drag and Drop UI using GWT with Connectors

[Santosh]

We have a requirement to create a diagram which shows a sequence of
process in circular manner with Connectors. UI should be flexible
enough so that user can drag and drop any process between any of the
other two process in the diagram. Automatically connectors should get
re-arranged with new sequence. All examples what I saw using GWT-DND
are drag and drop components, but no examples with Connector arrows
concepts. We have also heard about SVG and YUI. But I am not sure how
far we can use that within GWT. Do we have any suggestion on what to
choose and how we can design this?

Re: Adjusting height of GWT Panels based on content dynamically

[Santosh]

Thanks for your valuable inputs. As you have suggested, I will do some
reading on using css for fluid page design. Hope I will be more clear
afterwards. I will get back to you if any more clarifications needed.

Header Panel will help me to create a header, content and footer
area.  Anything more about that related to my issue?

Adjusting height of GWT Panels based on content dynamically

[Santosh]

We have many screens where different types of GWT panels are used. One
common problem across many screens is that, content size is derived at
runtime. So, if I define a height for a panel(Vertical/Horizontal/
DockPanel) and when any new components are getting added within panel
or content is more, panel height remains the same. So we are not able
to see the contents. UI look and feel becomes worst. How do we handle
the height problems? Do we have to manually code to adjust every panel/
widget height when something gets changed in screen. Is it not a very
bad way of coding?
Also, now we have datagrids at some places, if no of records are very
less, we see a huge space left out below datagrid, not sure how do we
handle these cases?

Somebody please suggest as it is quite urgent.

Session Management in GWT

[Santosh]

I have few basic questions on session management in GWTP.

1. Now, we create a new session when the user logs in to application.
Now, I can open a browser and type in the app url with a token
directly without logging in. It will render the UI page to user
without any checks. Now, we have session checks in server side. So if
the UI page make s a server call on rendering then only, I will get to
know session is not valid and i can redirect him to login page. But,
how do we handle the cases where UI page does not have any server side
logic and user directly paste the URL with that token.
Do I have to make a server call on every page request from GWTP
presenter just to check session is valid? or do we have any other
approaches to it?

2. I am not passing any explicit session id param from GWT Client to
server. Its only the JSessionId getting passed automatically from
browser to server. We just do request.getSession() in server and see
if it is null or not(Not logged in if null). So I hope we dont have
any security issues with this. Please confirm.

3. With GWT client running on android and server side logic exposed as
Restful Web services using Jersey, how do we maintain session because
Restful WS are stateless. Now how do we achieve user session in this
case?

GWT UI Layout

[Santosh]

We wanted to design a layout in GWT which has quite a lot of small
small sections on screen. Basically it has a left menu, header,
footer, main content area with lot of sub sections which can be closed
by user in case if he does not want to see them. Then remaining
content section should get adjusted automatically.  We are using GWT
Platform. I am in doubt, whether DockLayoutPanel suits for this or
not, because, it has to be must more flexible. Apart from that, I
didnt get any good layout examples. Can we achieve this using GWT
panels or we have to manually do it using div in module html file?

Mobile Development and Deployment using GWT, mGWT and phonegap

[Santosh]

I am really confused with lot of links mgwt, phonegap, cordova, gwt-
phonegap..etc.
can somebody really help me in understanding few of my basic questions
about all these?

a. Phonegap and Cordova are one and the same - They will help us to
build a mobile deployable component  using generated JS files. Am I
correct?
b. Steps provided in cordova site to create a Android project and
deploy needs generated html, JS and CSS content of our project. So we
need to build these build before we come here from our project. Rt?
c. Now if I have a simple GWT project, can I build GWT client and
deploy the generated web app content(.nocache.js and module html
files) directly using step b(Cordova approach) without any changes. I
understand that this itself is called a Phonegap project which we do
using this link "http://docs.phonegap.com/en/1.7.0/guide_getting-
started_android_index.md.html#Getting%20Started%20with%20Android"

d. Now if I have used mGWT widgets in my GWT application, what is that
extra needed before i start using Cordova steps- mGWT compiled code
can't be used directly in Cordova Phonegap project?
What is gwt-Phonegap? Why do we need this now? Please suggest me. Can
somebody really explain what exactly is happening using gwt-Phonegap
in some simple words.

Please help!!!

JSON Parsing in GWT Client

[Santosh]

We have use GWT Platform with GWTP client and rest web services within
GUICE container. Rest service invocation from GWT client is done using
JSONPRequestbuilder.

I want to know which is the best JSON response string parsing
technique for GWT? - JSON to Java serialization/deserialization

After lot of search on google, I found out that we have these many
options.

a. GWT built in JSONParser parseStrict method which is called secured
and best way to go. But this may not be suitable for complex JSON
response string. Becuase you need to write lot of code to parse each
item in JSON response and convert to a Java object.
b. GWT AutobeanFactory approach - I dont know how best to use this? We
are using GWT 2.4, you do not have any complete example of using this
approach at all. Everywhere, people say its an approach but no where
we have detailed description on this. Few samples on google were from
gwt older versions which were changed a lot in GWT 2.4.  Please
somebody share a good example with GWT 2.4 and Autobean factory
approach for JSON ser/deser...
c. JavaScript overlay types: People say it is not the secured way to
go. So I am bit hesitate whether we should use this or not.

Moreover, we are migrating from GWT to SmartGWT very soon. I hope, the
rest call services with these should continue to work even in SmartGWT
without any changes. (Because SmartGWT also comes with a predefined
format JSON rest support which we may not use as we already have built
these services in general).

Kindly advice asap.

Thanks

Re: Displaying a PDF in a GWT application using a servlet (or not)

[Santosh kumar]

Why do you want to store invoice info in the blob store ? Invoice data is
not meant to be fixed,
I mean client might update it at any time, again its over head you to go
and update it in the blod store.

Try this
http://pdfjet.com/
I suggest you to develop your own servlet, let this servlet do use of the
pdfjet api to generate invoice on fly itself, no worry of storing it.
Let the client do whatever he wants with that pdf file.

Hope it helps you.

Handle OnClick of GWT SuggestBox ?

[Santosh kumar]

Hi,

*onClick of the SuggestBox* i want to display some of the default
suggestions. Some how i am managing to get response from the server.

@Override
public void onClick(ClickEvent event) {
   -
   -
   -
   -
 // here some how i am managing to get the default suggestions from
the server.
   -
   -
   -
   -
// but my problem is how do i say *callback.onSuggestionsReady(req,
resp);* because callback is not available here ?

// *So, my work around was:* i just created a *new Callback*, and
after getting the response from the server i am calling
//  callback.onSuggestionsReady(req, resp);

Callback callback = new Callback() {

@Override
public void onSuggestionsReady(Request request,
com.google.gwt.user.client.ui.SuggestOracle.Response response) {
// *my question is, how do i Override* *onSuggestionsReady*
*and display the suggestions ??* *because control is coming here.*
}
};
}

is this is the right way ? or please can any one suggest me the right way ?

Thanks in advance :)

Re: Отг: Handling next and prev buttons of SimplePager ??

[Santosh kumar]

Hi Miroslav,

I have two questions:


   1. If i am keeping track of cursors, and what if i click *last page arrow
   button*, then how do i get the last 20(assume) values ??
   2. if i click *prev arrow button* then how do i display the last
   page(here i am understanding that pager holds the previous data so no need
   of call to the server).

Re: Отг: Handling next and prev buttons of SimplePager ??

[Santosh kumar]

Hi All,,

Because of some reason, Discussion subject changed to "*Отг:* Handling next
and prev buttons of SimplePager ??" for a reply.
And here in gmail i got that reply as a new thread. So only i am replying
from that new thread...

*But my thread was:*
Hi,

I am using GWT 2.3 cellTable to display the data using SimplePager.

And i am following the example *AsyncDataProvider* as it is...

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


AsyncDataProvider provider = new AsyncDataProvider() {
  @Override
  protected void onRangeChanged(HasData display) {

// Here i am doing rpc call to get the data *using cursors*... and
its working fine.

updateRowData(start, data);
  }
};

But each time when i click *next button* i am getting next 20 values from
the data store using cursor. And it is displaying the data fine. No issues
with next button.

But when i click *prev button*, i am assuming that cellTable had stored the
previously displayed data, and just want to display that existing data, and
handle this case without making RPC ?? but here when i click on prev button,
progress bar is being displayed... what is that wrong here ??

(*DOUBT*: *on click of prev button*: what is the need of call to the server
to get the duplicate data again ??)

is their any other way to handle this case ?? Please any suggestions ??


Thanks in advance

updateRowData(start, data);
  }
};

But each time when i click *next button* i am getting next 20 values from
the data store using cursor. And it is displaying the data fine. No issues
with next button.

But when i click *prev button*, i am assuming that cellTable had stored the
previously displayed data, and just want to display that existing data, and
handle this case without making RPC ?? but here when i click on prev button,
progress bar is being displayed... what is that wrong here ??

(*DOUBT*: *on click of prev button*: what is the need of call to the server
to get the duplicate data again ??)

is their any other way to handle this case ?? Please any suggestions ??

Re: How to get list of objects from JSON ??

[Santosh kumar]

Hi ,

Moitra and Thomas

Thanks for your reply.. !!

Anyways i got a solution..

*use this code in the servlet* ---
- get the list of products (productList) and use it in the servlet:
- This is JSON format to form a array of objects

// Open the  tag
writer.append("<script type=\"text/javascript\">");
writer.append("var product=");
writer.append("{productList: '[");

Iterator<Product> iter = productList.iterator();
while (iter.hasNext()) {
Product product= iter.next();
writer.append("{productName: \"" + Product .getProductName() +
"\", id: " + Product .getId() +
", productDetails: \"" + Product .getProductDetails() +
   .
   .
  "\"}");
if (iter.hasNext()) {
writer.append(",");
}
}

// End the <script> tag
writer.append("]'}; ");


*use this code in the GWT onModule *---
- call the above servlet on onModule

Dictionary product= Dictionary.getDictionary("product");
String productListStr = product.get("productList").toString();
JSONArray productJSONArray = JSONParser.parse(productListStr
).isArray();
List ProductList = new ArrayList();
for (int i = 0; i < productJSONArray .size(); i++) {
JSONObject productJSONObject = (JSONObject)productJSONArray
.get(i);
Product product= new Product();

JSONString productNameJSONString = productJSONObject
.get("productName").isString();
product.setProductName(productNameJSONString .stringValue());

product.setId(Long.valueOf(productJSONObject
.get("id").toString()));

.
.

ProductList .add(product);
}

finally we will get a list of objects. i.e, ProductList .

Guys its really cool concept .. !! enjoy it !! :-)

Re: showing all the elements from SuggestOracle in suggestionBox

[Santosh kumar]

Hi *ciosbel*,

Thank you for your reply ..!!

As u said, i am using setDefaultSuggestionsFromText method, its working
fine.. !!! i thought solution would be very difficult...
Its coool !! thank you once again !!!

setDefaultSuggestionsFromText(Collection suggestionList)
using this method, if their is no match found for the key pressed, Here i am
displaying nothing. But after onChange its displaying the
DefaultSuggestList.

But my thinking is immediate onPress of the key i have to display the popup
DefaultSuggestList if their is no match found for the key pressed.


Please let me know if you know the solution ..!!
