Re: GWT webapp into an IFRAME

2011-02-02 Thread aditya sanas

hi,
yeah ofcourse it will work
i have implemented it in my projects but you might require to check browser
compatibility for frame size and some minor changes
but this works for sure.

 Hello

 I've done a GWT app which is running on it's own page; but I've a
 request to embed the page into a portal.
 As I need to get the job done ASAP; I'm thinking about embedding the
 GWT weapp into a iframe, as


 iframe src=app/myapp.html/iframe

 Would it work ?
 Can a GWT app detect when it's running on a top page or on a iframe ?


 Thanks

Re: Db Connectivity

2010-12-09 Thread aditya sanas

Hi,

The code you write in java gets converted into javascript this is what GWT
does so GWT works on client side
so there is some restriction on usage of classes and packages that u refer
in GWT code just like *java.sql. or java.io*
*these packages are not available on client side*
So to use these classes,GWT has provided server side where you can access
these classes so make ur connection on the server side do processing and
send result back to client.
Async calls would be helpful in this case.

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

2010-12-03 Thread aditya sanas

hi dominic,


I m receiving key press event in all the browser the thing that i have
noticed which doesn't work in GWT 2.1 is -

 *if(event.getCharCode()==KeyCodes.KEY_ENTER){ *

the o/p of event.getCharCode() in GWT 2.1 is nothing not even 0 so i cnt
compare it with KeyCodes.KEY_ENTER

i had tried one more new method that has been introduced in GWT 2.1 which
getUnicodeCode() which gives 0 whenever i presses ENTER but this is not the
right because i m getting 0 even when i m pressing any arrow key.

how to figure this out...?

Re: TabPanel tabs size are not same

the verticalpanel inside that each tab must have fixed width and height

Each of the getTabPageX() method return a VerticalPanel which in turn

Kindly advise how to make the tab size homogenous among all tabs

Re: communication between two frames

 thanks for ur reply and kind help.
i am still searching for the right solution.
I have implemented what u have specified in the la st thread as -
 $wnd.myBus.fire(myModule,initState)
 this works fine  when i m opening both  the modules in different (seperate)
windows of the same browser. but whenever i try this using inner frame it
doesn't work as it should be.

so for guiding purpose if you can  share a code snippet that might help me
for better understand.

And yes,we had thought of  code splitting but we couldn't implemented it.

 ah ok got your point, well, if you write:

 @com.verisona.bridge.client.CandidateMainView::alertWindow();

 for the GWT compiler is pretty same as a pure Java call - because that
 code is not actually native where as

 $wnd.alert(foo)

 is a real native code which is not handled by GWT compiler. the first
 line would not work cross anonymous modules (such as those which are
 not compiled within same compilation process) since the obfuscator
 will rename all the types/method names. when I've written native i
 really meant pure Java-Code which is not compiled by GWT compiler, but
 rather is supplied from a separate codeBase.js (javascript) file.
 because that code you always can use cross-modules like
 $wnd.myBus.fire(myModule,initState).

 The issue is that you have to compile all available modules in same
 compile process to get them working with each other via compile time
 binding (such as calling ModuleA.refresh() from ModuleB), after
 compilation (with obfuscation) there is no way to reach the code via
 API.

 Have you already tried code splitting feature to minimize the initial
 bootstrap? so that codebase from moduleX is loaded on demand?

with another RPC call.

The problem that I have is:

If I change the value of the field, and, without losing the focus, I

Re: how to transmit an image over rpc?

2010-09-08 Thread aditya sanas

Hello,
i think u got it right.
u can implement it in away as Thad has suggested.
u can even implement it for simple img src as it is also hitting an URL
so u can have a servlet and can give a src as download?imgID=demoImage
and on the server side in the servlet which is serving a request for
/download will send the content for that file.

this works as i have used same method in my projects.

Hi,

what I am trying to do is a photo album.

There is a directory structure on the server with an index.xml file in
each directory. On startup the index files are scanned and the
content directory is passed over rpc to the client. The client
displays nice menus and if the user selects an entry the images should
be shown.

If I pass URLs via rpc then the image directory must be world
readable.

Your advice with the servlet: Do you mean that the servlet should
return the image data itself and the setURL method of the Image class
knows that this is not a URL but the raw image data? Have I got you
right?

How would you realize what I want?

Thanks

You can't, at least not directly. GWT does only what HTML does, and
in HTML images are loaded via the SRC attribute in an IMG element.
You can write basic doGet/doPost servlet that returns and image and
put use its URL in com.google.gwt.user.client.ui.Image.setUrl() (which
sets the SRC attribute).

If you feel you must use an RPC call for the image, have the RPC call
return a java.lang.String of the image (GIF, JPEG, or PNG) in Base
64. In the onSuccess() method, use that result String as the argument
for setUrl().

Including conditional CSS files accordingly as follows:

*
*link type=text/css rel=stylesheet href=styles.css /*
*!--[if IE 6]link rel=stylesheet href=style.ie6.css type=text/css
/![endif]--*

you can style ur page accordingly in style.ie6.css which will be applied to
IE 6 only.
In case of Chrome try and debug project what exactly happening while loading
modules.
do you get any error messages while displaying page in chrome?

At very first step set the size of horizontal panel as
hrzPanel.setSize(350px,500px);
then set the size for scrollpanel in percentage or you can set it same as
above.
this will work for sure.
also if you want scrollbars bydefault then set the method for
scrPanel.setAlwaysShowScrollBars(true);

Re: click event in dialogbox

yeah it is possible.

you just need to create Anchor(String )  from GWT

and register a onclick event for this anchor as Anchor.addClickHandler();

using this you will be able to bind onclick with the link you desired.

 This code is from my class that extends Grid:

 public GridMouseHandler gridMouseHandler = new GridMouseHandler(this);

 Later on in the workings of one of the functions I add my mouse
 handlers. For grids or flex tables they must currently be implemented
 as dom handlers:
addDomHandler(gridMouseHandler,
 MouseDownEvent.getType());
addDomHandler(gridMouseHandler, MouseUpEvent.getType());
addDomHandler(gridMouseHandler, MouseMoveEvent.getType());

 My function that finds which cell the mouse event happened on:
public int[] getCellForEvent(MouseEvent? event) {
final Element td =
 getEventTargetCell(Event.as(event.getNativeEvent()));
if (td == null) {
return null;
}
final Element tr = DOM.getParent(td);
final Element table = DOM.getParent(tr);
int returnEventPosition[] = new int[2];
returnEventPosition[rowPos] = DOM.getChildIndex(table, tr);
returnEventPosition[colPos] = DOM.getChildIndex(tr, td);
eventPosition[rowPos] = returnEventPosition[rowPos];
eventPosition[colPos] = returnEventPosition[colPos];
return returnEventPosition;
}

 My GridMouseHandler class is just: public class GridMouseHandler
 implements MouseDownHandler, MouseUpHandler, MouseMoveHandler { and
 then implements the required methods such as onMouseUp, or
 onMouseMove, and when the mouse moves you can have them call a
 specific function. One of the functions you will want to call is your
 own function for finding which cell the event happened on, and then
 acting accordingly.

 Using this same method you can do similar things for any of the mouse
 handlers with Grid.

Re: GWT serialization

2010-08-17 Thread aditya sanas

The basic requirement for you is to deal with XML file

So we have jxl.jar which provides APIs to interact with tags and elements in
xml so

using these API's that are generally known as XML parsers that is SAX or DOC
parsers.

so use by using these parsers you will be able to deal with XML files.

It wont be that difficult for you once you learn how to use these parsers.

You will need external jar file jxl.jar

Hi,

check for click handlers that you are registering for that particular link
Ideally it should work fine...
meanwhile if you are losing that event handler after first click then and
then only this problem could be faced.
I never faced such kind of situation with the links
I used Anchor from GWT...

Re: showing all the elements from SuggestOracle in suggestionBox

2010-08-12 Thread aditya sanas

Hello,

yes you are right we dont have direct access to SuggestBox Popups.

I have already extended SuggestOracle and have overridden method

requestSuggestion(request,callback);

code for the following as follows :

public class StartsWithSuggestOracle extends SuggestOracle
{
   //...  some other code...

*@Override*
*public void requestSuggestions(Request request, Callback callback) *
*{ *
*final List suggestions =
computeItemsFor(request.getQuery().toLowerCase(),request.getLimit()); *
*Response response = new Response(suggestions); *
*callback.onSuggestionsReady(request, response); *
*} *

}


and the underlined method computeItemsFor(); returns me the suggestions
based upon request so as per my

logic if request contains no character that is an empty string  i have
returned all suggestions from oracle object.

so here i m able to get this response correctly but i m nt getting wht
should be done next with this response.

from where i should give a call to this method and how that list get
populated.

I have followed that link suggested by you but that was the same mechanism
that used there.

so i m lil confuse why its not showing the response.

 Hi Aditya,

 The problem is that you don't have direct access to the SuggestBox
 popup.

 If you want to see all the possible solutions you should extend the
 SuggestOracle and implement your own requestSuggestions method (see
 this link for some nice examples: http://development.lombardi.com/?p=39)

 In this way yo can simply return all your list, even ignoring the
 limit.

 Regards,
 Carlos.

Re: Incubator - GWTCanvas problems with image loading

2010-08-10 Thread aditya sanas

Look at this error message

Aug 9, 2010 10:17:54 PM
com.google.appengine.tools.development.LocalResourceFileServlet doGet
WARNING: No file found for: /mywebapp/GoogleCode.png

It is showing that server is trying that GoogleCode.png under
/mywebapp/GoogleCode.png
Where it is not finding
So try and figure out where exactly it is searching for that image and you
have to debug it by yourself as this is an issue
of putting files in right place and referring those by right urls.

Hi Aditya,
Well I have two apps, once is an App Engine variant, and they are a
little different in their response, although neither will display the
image.

My App Engine version (when running in hosted mode) displays in red
on the console that two files can't be found:

Aug 9, 2010 10:13:51 PM
com.google.appengine.tools.development.LocalResourceFileServlet doGet
WARNING: No file found for: /favicon.ico

Aug 9, 2010 10:17:54 PM
com.google.appengine.tools.development.LocalResourceFileServlet doGet
WARNING: No file found for: /mywebapp/GoogleCode.png

The hosted mode of the non-App Engine version types out some kind of
information that looks like header info or request info, but no paths
or filenames.

In the browser, the image just doesn't show up, ( unless I use a full
URL, that is. )

I'm using Eclipse on Windows.

I have added a GWTCanvas to the demo app and am trying to load an

omething like this:

http://code.google.com/p/google-web-toolkit-incubator/wiki/ImageLoader

My problem is that the image only loads and displays if I have a
complete URL like

// String[] imageUrls = new String[] {
http://www.knivesplus.com/
media/SC-104OT.jpg}; /* This works fine */
String[] imageUrls = new String[]
{images/GoogleCode.png}; /*
This does not work. */

However, I have created an 'images' folder in my war folder in
Eclipse, and the following image in the HTML displays just fine:
img src=images/GoogleCode.pngimg

I don't understand why the app has no problem reading the image from
the relative path when displaying the HTML, but cannot find the image
using the ImageLoader class.

What can I do so that I can add images to my eclipse project which I
can then use with GWTCanvas?
