Re: TabLayoutPanel doesn't show its content

Is there any working example that uses TabLayoutPanel?

Re: Page navigations in GWT
Yes, i used a similar approach. I have a main panel which is always present, and i add and remove composites on need. I too have a Search screen, on click on the search button, i remove the Search composite from the panel and add the search results composite. I have a seperate HashMap of composites, instead of creating the composites every time a button is clicked, i create it once on the first request and store it in the hashmap, and retrieve it from there. The login screen is a JSP page, after authentication, i load the main panel inthe onModuleLoad function. Hope this helps.

Check this video for doing best practices:http://www.youtube.com/watch?v=PDuhR18-EdM I would do the search page as stated above, create a searchEvent, a searchEventHandler, and either work with a eventbus or, if it's a simple app, just register the handler to the search result page, and fire the search event with the search button.

result )

results into array, this is in my com.xxx.login.server.PSQLConnection

I also have a class which is responisble for drawing the webpage etc
com.xxx.login.client.Report.
I have no idea at this point how to pass this array from the server to
the client.
Any ideas ?

Re: Aligning labels and fields
I am using a FlexTable and i have more than 10 fields. I too use the
setWidget to see each of my fields.
but i dont set the style for each single field seperately.
Since your input textboxes use the same style and all your labels uses
teh same style:
you can reduce the lines to set styles for these by having a seperate
css file:
say: MyStyle.css and you can include this CSS in your
Application.gwt.xml as
stylesheet src='MyStyle.css' /
and you can define the style as follows:
.gwt-Label {
//your style for labels
}
.gwt-TextBox {
//your style for textboxes.
}

Satya

I'm using Grid because I want the labels and fields to be aligned.
The code becomes ugly when there are 10 or more fields!
Can you share your experience in aligning the labels and fields (form) in
plain GWT?

GWT incubator problems in migration from 1.4 to 1.5
We are using GWT 1.4 and gwt-incubator_1-4_final.jar in our project. we want to migrate to GWT 1.5 , but we are facing problem in migration. i tried with, 1) GWT 1.5 , gwt-incubator_1-4_final.jar it is unable to generate the sript file. TreeLogger is abstract class in GWT 1.5 , but in 1.4 it is interface, so the gwt-incubator_1-4_final.jar is excepting that. 2) GWT 1.5 , gwt-incubator.jar(1.5) it is unable to compile. Some of the classes are removed from the latest incubator, but our application is using those classes. What are the step required or posible solutions to migrate from gwt 1.4, gwt-incubator_1-4_final.jar to gwt 1.5, gwt- incubator_1-4_final.jar(because we are not going use incubators from now onwards) . --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: set border colr onFocus
I have found that i can have a style defined in CSS Style sheet:
gwt-focus {
border: 1px solid #FF;
}
and have this applied to a widget on its focus
for example: myTextBox.addFoucsListener(new FocusListener){
public void onFocus(Widget arg0) {
// TODO Auto-generated method stub
arg0.addStyleName(gwt-focus);
}
public void onLostFocus(Widget arg0) {
// TODO Auto-generated method stub
arg0.removeStyleName(gwt-focus);
}
});
But it is bad that i have to add the listener for all the widgets that
needs this change. :(

Re: Exception handling in GWT Service
There is a SerializationException

Looked at the SerializableException in gwt... it is just an Exception

Thanks Ravi for clarifying.
BTW, in 1.5 gwt supports serialization of objects implementing
java.io.Serializable.
So just by extending Exception it would work.
Thanks again,
Jossey.

Quite the contrary, actually. I started off with a custom exception
which was merely a child class of Exception that I intended to use in
RPC calls (i.e. service methods throw it). This actually didn't work
in the ways expected, i.e. when the server threw the exception I was
unable to retrieve the exception message in the client, or find out
what the cause was. Which is when some digging around revealed that if
you want to send the exception over the wire, it has to be a GWT
SerializableException.
This is with 1.4.6x, of course this may have changed in 1.5.x, I am
not sure.

MyRPCException {
SomeReturnedObject ret = null;
try {
// Do stuff to populate ret. This stuff could
potentially fail.
} catch (SomeNonGWTSerializableServerSideException e) {
throw new MyRPCException(This is an error message that
may be appropriate to show in the UI: + e.getMessage());
}
return ret;
}
5. In your AsyncCallback in the client:
public void onSuccess(Object result) {
SomeReturnedObject foo = (SomeReturnedObject) result;
// Happiness and tranquility reign supreme
};
public void onFailure(Throwable exception) {
try {
throw exception;
} catch (MyRPCException e) {
// Show the error message to the user,
// or handle however you want to.
}
};
This should work, there may be some overkill in this though. All this
is GWT 1.4.6x, I'm not sure if any of this has changed in 1.5.x.

public void onClick(Widget sender) {
if (textBoxUsername.getText().length() == 0 ||
textBoxPassword.getText().length() == 0) {
Window.alert(Username or password is
empty.);
}
else
{
//once the user name and the password
is right
//it comes here
}
}
});
signInButton.setText(Sign In);
}
}
actually, for validating it from the database i need to transfer the
username and password textbox value to another java class for database
connectivity..so, can anyone help me in transferring the data from
Login class and ValidateLogin class(its listed below)
public class ValidateLogin {
Backend bk = new Backend();
DataSet ds = null;
public static void main(String[] args)
{
Login log = new Login();
String query=select * from users where
username='+log.textBoxUsername.getText()+';
query+= and password='+log.textBoxPassword.getText()
+';
ds=bk.executeQuery(query);
if(ds.rowCount()!=0)
//correct login
else
//incorrect login
}
}
Thanks in advance,
-Sharma.

Re: Wait creating an object tilll RPC result comes
I use an gwt-ext messagebox (progress box) that get displayed until i
finish my RPC service call.
For example:
MessageBox.show( new MessageBoxConfig() {
{
setTitle( Creation the rule );
setMsg( Please wait... );
setProgressText( Creating... );
setWidth( 300 );
setWait( true );
setWaitConfig( new WaitConfig() {
{
setInterval( 200 );
}
} );
// setAnimEl(next.getId());
}
} );
timer = new Timer() {
public void run()
{
MessageBox.hide();
System.out.println( Done, Created rules! );
}
};
In my onSuccess of my RPC Call, i cancel the time and hide the
messageBox:
public void onSuccess( Object result )
{
timer.cancel();
MessageBox.hide();
//perform other actions
}
Hope this helps.
Thanks

Re: How to use RichTextToolbar ?
You can look at the KitchenSink demo, to follow to include RichTextToolbar. Here is what i did: 1. Included RichTextToolbar java, and the RichTextToolbar $Strings.properties in my client package. 2. Created an icons folder under client, and copied all images required by RichTextToolbar 3. Modified the RichTextToolbar to include the current location of the images/gifs. I hope this helps, Thanks Satya On Nov 25, 1:52 am, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hello everybody: In my item , i must use the discreteness.Who can give me a example?

Re: Exception handling in GWT Service
Thank you very much,
I guess i can return the String IllegalDateRangeException when
throwing that exception from my Service and check for that in my
onFailure class.
public void onFailure( Throwable caught )
{
if ( caught.getMessage().contains
( IllegalDateRangeException ) )
//handle my class.
}
Thnak you,
Satya

Also
when i call the actual method, does the exception get caught in the
failure method or in my catch method?
For example:
AsyncCallback callBack = new AsyncCallback() {
public void onFailure( Throwable caught )
{
//Is the exception caught here?
here !
}
public void onSuccess( Object result )
{
}
try
{
createNewRuleService.createRule( screenType,
eventRuleForm, callBack );
}
catch ( IllegalDateRangeException e )
{
or the exception is caught here?
}
You should notice the differences between RemoteInterface and its
Asyn counter part:
* return type: the asyn interface method doesn't have return value
=== it will be pass as parameter asynchronously in onSuccess
callback.
* exception: are not part of the async method === it will be pass
as parameter asynchronously in onFailure callback.
Thank you very much for your help. I appreciate it.

my method signature looks like:

Hi,

Yes as long as your exeption is declared in the Service Signature (to
be declared as GWT serialisable).
I created an userdefined exception:
--
public class IllegalDateRangeException extends SerializationException
implements IsSerializable
{
private String errorMessage = null;
public IllegalDateRangeException ( String error )
{
errorMessage = error;
}
public String toString()
{
return Exception occurred: + errorMessage;
}
public String getErrorMessage()
{
return errorMessage;
}
public void setErrorMessage( String errorMessage )
{
this.errorMessage = errorMessage;
}
}
and my RPC method throws this exception:
public String create(Rule rule) throws IllegalDateRangeException;
and i want to catch this exception in the client side and perform
actions.
But i get the following error from GWT:
[ERROR] Type
'com.cerner.cwx.ruleswizard.client.IllegalDateRangeException' was not
serializable and has no concrete serializable subtypes
Any suggestions?
Any help on this is greatly appreciated.
Thank you
Satya
