Re: custom event + event bubbling

[ashwin.desi...@gmail.com]

for listening on events on your widget you can define UiHandler or Attach /
Add handlers

for example, if you have a button defined in your UIBinder

Hello

now if you want to listen on click event of this button, you can do either
of these two operations

@UiHandler("button1")
public void OnButton1Click(ClickEvent event) {
 ///do what ever you want on button click
}

when you are not using a UiBinder you can define

button1.addClickHandler(new ClickHandler() {
 @Override
public void onClick(ClickEvent arg0) {
//do your opertaions
}
})


hope this is clear.

Thanks
Ashwin

Re: No source code is available for type com.google.gwt.user.server.rpc.RemoteServiceServlet; did you forget to inherit a required module?

[ashwin.desi...@gmail.com]

Nicolas,

The first this I can think of is in your module definition you have not
included the path



Your UserServiceImpl is defined in your server package but you don't have
that included in the module.

Try adding that.

Re: RequestFactory object lifecycle & change propagation

[ashwin.desi...@gmail.com]

J,

did you look at EntityProxyChange.registerForProxyType ? You can use this
and register for any changes to your entities with the eventBus. The Handler
method is called on change of entities (especially version changes).

example:

EntityProxyChange.registerForProxyType(eventBus, UserContactsProxy.class,
new EntityProxyChange.Handler() {

@Override
public void onProxyChange(
EntityProxyChange arg0) {

  proxyId =
arg0.getProxyId()
 //data has changed, so fetch the contact again
fetchUserContact(prxoyId);
}
});

Regards
Ashwin

RequestContext & GAE EntityGroups?

[ashwin.desi...@gmail.com]

Hello,

I am building a project where I have a datamodel as shown below.


A {

@Transient

B b;


@Transient

C c;


}

//there are few more params, just showing the basic structure
B {

String title;
Set child;

}

C {

//set of keys is stored
Set d;
Set count;

}

D {

String name;
String country;

}

As I am using Spring-Roo for generating my entites it automatically only
store only keys/ primary id's of the referencing entities.

All entities are rendered using custom widgets. I am using Editor frramework
to edit the entities.

On my parent View (which displays Entity A), I have a save button, on click
I persists all the children (B, C) and the parent  Currently I make
individual calls to persist each entity set in the datastore.

I have two challenges

1. Can I combine the request to persist all of these entities into a single
call using entitygroups? Can this be achieved using RequestContext &
RequestFactory framework. Any advice/ suggestions would be much appreciated

2. If I go with my current approach of saving all entities separately, even
though it works well, the implementation becomes messy when I have to
re-edit the Objects. for example, I had to display details of Object A in my
home page, so I fetched A from datastore, while doing so I used the with
clause as below

requestContext.findAllA().with("b")

now if I pass this retrieved proxy to the editor framework, it not only sets
the object A to edit mode, it also sets the Object B to edit. Without entity
groups, I cannot persist any changes to B along with A. The only way for me
to save B (using my current approach to save entities separately) is to use
AutoBeanUtils and freeze the entity B, dis-associate the requestContext
reference and re-edit it using a different requestContext.

This approach works, but i feel its messy and there should be a better and
cleaner approach to achieve data persistance.


Appreciate all your advice/ suggestions.

Thanks
Ashwin

Re: RequestFactory and populate form field with dynamic data

[ashwin.desi...@gmail.com]

you should be able to dynamically populate a drop list using requestFactory.
Once you fetch the data from the server, you can update your list.

The only instance where you would have to build a custom widget is when you
want to dynamically populate a SelectionCell with your dynamic data. For
that you can refer to the following link

http://stackoverflow.com/questions/4565790/how-to-dynamically-update-the-choices-in-a-selectioncell-using-gwt

Re: Making a button fire inside a custom AbstractCell

[ashwin.desi...@gmail.com]

 you have not specified the events you want your cell to consume. You will
have to add a constructor and specify the events you want  to consume

AbstractButtonCell() {
super(new String[] { "click", "keydown" });
//do rest of the init;
}

Re: RequestFactory object lifecycle & change propagation

[ashwin.desi...@gmail.com]

since you want to update your in-memory list you can look at custom events
and pass the updated object by throwing an event whenever your contact was
modified. Your contact list can listen for this custom event and update the
existing object with new data.

with regards to EntityProxyId, you have to main a map of your proxies and
their proxyId's. this way you whenever a proxy has changed, you can pick the
corresponding proxy from the map and update it by fetching new data from the
server.

Thanks
Ashwin

Re: Questions about complex UI events in MVP mode

[ashwin.desi...@gmail.com]

Victor,

based on what I read, your flowpanel is part of a view which is mapped to a
presenter. You are dynamically adding buttons to the flowpanel. You can
setup click handlers for each of your buttons. if the button is present and
clicked, its handler would be invoked. Inside the handler call the presenter
of the view to perform what ever operation you want to

for example :

interface view {


void setDelegate(Delegate delegate);

interface Delegate {
void save();
}

}


public class MyView extends Composite implements view {

Delegate delegate;


public void setDelegate(Delegate delegate) {
   this.delegate = delegate;

}

public OnLoad() {

FlowPanel panel = new FlowPanel();

Button btn = new Button("Click Me");

panle.add(btn);

btn.addClickHandler( new ClickHandler() {

public void onClick(ClickEvent event) {

delegate.save();
}

});

}

}


Thanks
Ashwin

Re: ListBox with multiple selection

[ashwin.desi...@gmail.com]

Associate a MultiSelectionModel with your list box. On the selection change
event, you can do the following

selectionModel.getSelectedSet();

this would fetch you all selected items.

Re: tab layout suggestions needed

look at the source code, the initialize method shows how to add new tabs.
You can add a button in one of these tab panels and on click of it create
new tabs.

Re: Configuring Places to work with Tabs

[ashwin.desi...@gmail.com]

Mark,

I think you should be able to achieve it using places. Try to have an
additional property in your place, lets say location which would tell you
which tab the user clicked. Now pass this value to the activity/ Delegate
which drives your view.  Based on the location render the contents.

Regards
Ashwin

Re: Configuring Places to work with Tabs

[ashwin.desi...@gmail.com]

render to the content inside your tab panel. ie. each tab panel has a header
(for rendering the tabs) and a content area. your view should expose the
content area as a widget. Your activity should render to this widget

use an absolute panel and render the image inside it. use absolute position
to render your images at the prescribed positions.

Re: Place an Image into the center of DockLayoutPanel ??

Very good.

if you are doing more than one image then placing them relative to each
other would be difficult using a HTMLPanel and table combination. In those
instances you can use an absolute panel

Re: ClientBundle don't load the ImageResource

[ashwin.desi...@gmail.com]

include the statement INSTANCE..ensureInjected(); that should fix your
problem.

For your reference read the following
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#ImageResource
Overview

   1. Write a CSS file, with or without GWT-specific extensions
   2. If GWT-specific extensions are used, define a custom subtype of
   CssResource
   3. Declare a method that returns
CssResource
or
   a subtype in an
ClientBundle
   4. When the bundle type is generated with GWT.create() a Java expression
   that evaluates to the contents of the stylesheets will be created
  - Except in the simplest case where the Java expression is a string
  literal, it is generally not the case that a CSS file could be generated
  into the module output
   5. At runtime, call CssResource.ensureInjected() to inject the contents
   of the stylesheet
  - This method is safe to call multiple times, as subsequent
  invocations will be a no-op
  - The recommended pattern is to call ensureInjected() in the static
  initializer of your various widget type

Re: Place an Image into the center of DockLayoutPanel ??

[ashwin.desi...@gmail.com]

all layout panels have to be placed under other layout panels otherwize they
won't render properly as the resizing would not work automatically. You can
alternatively use a ResizeLayoutPanel which is an extension of a
SimplePanel. Use it instead of the simple panel.

Re: TabLayoutPanel expand to fit content?

[ashwin.desi...@gmail.com]

you are having this problem because your page is not able to resize
properly. What sort of widget is your  is that a Simple Panel?

 you can place your Tab Layout Panel directly inside the RootLayout Panel.
since you want to have two Tab Panels, place them inside a simple panel
would not work properly. Instead use ResizeLayoutPanel (this is an extension
of SimplePanel) which can automatically resize.

Re: ClientBundle don't load the ImageResource

[ashwin.desi...@gmail.com]

sorry,

hit send too early... here is the example

public interface DesktopResources extends ClientBundle {
 @NotStrict
@Source("desktop.css")
CommonResources commonResources();
 @Source("./images/app_logo.png")
ImageResource appLogo();
}

public interface CommonResources extends CssResource {
/**
 * Width of the Main Page
 */
int pagewidth();
 /**
 * application logo
 */
String appLogo();
}

desktop.css
/* css file definition */


@def pageWidth 1000px;

@sprite .appLogo {
gwt-image: 'appLogo';
float: left;
}

/* end css file def */

you need to define a main Style class which you can use to refer all your
resources

public class Style {
private static DesktopResources resources;
 static {
resources = GWT.create(DesktopResources.class);
resources.commonResources().ensureInjected();
}
 public static CommonResources common() {
return resources.commonResources();
}
 public static DesktopResources resources() {
return resources;
}
}


now in each of your UiBinder define the following line. This would allow you
to refer the styles defined in your css files. Its a good practice to
centrally define all the styles in a CSS files as this would help in easily
managing your changing styles for the page








Thanks
Ashwin

Re: Configuring Places to work with Tabs

[ashwin.desi...@gmail.com]

i would recommend the following approach,

in your AppEntry/ main class define the HistoryMapper something  similar to
the following

//default place
final Place defaultPlace = new Home(userName);

// Start PlaceHistoryHandler with our PlaceHistoryMapper
AppPlaceHistoryMapper historyMapper=
GWT.create(AppPlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new
PlaceHistoryHandler(historyMapper);
historyHandler.register(placeController, eventBus, defaultPlace);

// Goes to the place represented on URL else default place
historyHandler.handleCurrentHistory();



here i am considering the following as my distinct places Home, Accounts,
Search

My AppPlaceHistoryMapper is defined as below

@WithTokenizers(value = { Home.Tokenizer.class , Accounts.Tokenizer.class,
Search.Tokenizer.class})
public interface AppPlaceHistoryMapper extends PlaceHistoryMapper {

}


lets just look at my home place

public class Home extends Place {
 private String helloName;

public Home(String token) {
super();
if (null != token)
this.helloName = token;
else
this.helloName = "GUEST"; //guest user
}

public String getHelloName() {
return helloName;
}
 public static class Tokenizer implements PlaceTokenizer {

@Override
public Home getPlace(String token) {
return new Home(token);
}

@Override
public String getToken(Home helloPlace) {
return helloPlace.getHelloName();
}
 }
}


lets assume my view has a tablayoutpanel and each of my first tab is the
home place and second tab is the accounts place

on click of the tab, make your view forward the request to the delegate. The
delegate would determine which tab was selected, now if its a tab the
delegate does not handle or determines its a place change event then it
throws a placeControllder.goTo(new Accounts()); //issue a place change event


You have to define an ActivityMapper for your application

public final class AppMasterActivities implements ActivityMapper {

private ApplicationRequestFactory requests;
private PlaceController placeController;
 @Inject
public AppMasterActivities(ApplicationRequestFactory requests,
PlaceController placeController) {
this.requests = requests;
this.placeController = placeController;
}

   @Override
public Activity getActivity(Place place) {
if (place instanceof Home) {
  //call home activity or which ever activity would
render your home tab
 return new HomeActivity(requests, placeController);
}

else if(place instanceof Accounts) {

  //call accounts activity
   return new AccountsActivity(requests,
placeController)
}
  }


Now , you place is mapped to activities and history through the above
definitions.

When you move between tabs history mapping would automatically happen and
the corresponding activities would be invoked and pages fetched.

Ashwin

Re: TabLayoutPanel expand to fit content?

[ashwin.desi...@gmail.com]

the problem is not with your TabLayout panel. what you have there would work
fine. The issue is with the Grid.

Its best to use LayoutPanels inside other layoutpanels. In your case if all
that you are doing is rendering two TabLayoutPanels, you don't have to
necessarily use a grid.

i would instead try the following options

Option 1:

use a SplitLayoutPanel and add it to the RootLayoutPanel. render both your
tablayoutpanels to this panel.

Option 2:

Use a HTMLPanel instead of the grid, with two ResizeLayoutPanels. Render a
TabLayoutPanel to each of these resize Panels.

Re: CSS right and bottom margins Not showing

[ashwin.desi...@gmail.com]

reduce the width of the topPanel. try to inspect the resizelayoutpanel, it
would be going out of the frame. If you set overflow : auto, you may mostly
see a scroll bar. if you reduce the width to below 100% your right margin's
 should get set.

Re: TabLayoutPanel expand to fit content?

[ashwin.desi...@gmail.com]

are you setting 100% as the height for both the resize layout panels? if yes
how will the page render as your total height is 100% and you are assigning
to the 1st resisze panel, the second panel would not be able to calculate
its layout details.


try setting the height to 50% and see the out come.

Re: TabLayoutPanel expand to fit content?

[ashwin.desi...@gmail.com]

oh, if you want to render your panels on click of a button, then you don't
necessarily need two ResizeLayoutPanels, just render the contents of the
appropriate tabLayoutPanel

alternatively, you can set the visibility of the panels to true/ false on
click. this would also force the height adjustment. But I would recommend
the first approach

Thanks

Re: Changing the Place History without really going to a place

[ashwin.desi...@gmail.com]

best would be to do a place change, call the same activity, but re-use the
view (you can mark it singleton). this would make the code clean.

Re: how to make DataGrid column heading looks like swing table heading

Daya,

you can customize the style of the DataGrid by overriding the CSS

Re: Resubmitting RequestFactory request when server side logic requires it

[ashwin.desi...@gmail.com]

Ryan,

You can create your own custom annotation (for example : LoggedIn). Apply
this on all methods you want to authenticate the user/ session to be
validated.

Define your own ApplicationRequestFactoryServlet and
ApplicationServiceLayerDecorators. Override the invoke method under
ServiceLayerDecorator and validate for the presence of @LoggedIn
annotation. If present, check if the user session is valid.

regards
Ashwin

Re: Should I use HTML5 canvas just to create my own slideshow reader ?

[ashwin.desi...@gmail.com]

there are multiple options available apart from HTML5 canvas.

1. RapahelGWT (this is an extension of Raphael JS for GWT), using this
images would be rendered as SVG. And raphael works with lower versions of
ie as well http://code.google.com/p/raphaelgwt/
2. you can also look at a SlidingPanel (example of this is provided in
expense tutorial), and customize it to load your images.
3. vectomatic (gwt project available), an svg & html5 canvas plugin for
GWT.  http://code.google.com/p/vectomatic/

svg is supposed to be more suited for static images and interactivity.
HTML5 canvas when there is lots of animation/ computations involved.

the following video link provides a good introduction to html5 and
showcases differences between svg and canvas

Re: Facing issue while designing UI in GWT

[ashwin.desi...@gmail.com]

simply put GWT is a client side library. you develop using java/ phyton or
Go instead of javascript.

Its is similar to packaging a jsp/ html page inside a web app and would run
under any j2ee container.

yes you can combine, servlets and jsp in GWT app.

Re: PopupPanel size problem

[ashwin.desi...@gmail.com]

are you setting the size of the docklayout panel or making it use all the
available size of your popuppanel? Yes you can use window %.

I would suggest you set min width and height for your popup panel and make
the docklayout panel cover the width and height of your popup.  Setting min
width and height would ensure that even on small screens your widget would
render tidily.

Re: How do I make sure Widgets receive mouse events if placed in front of a Canvas or Vaadin DrawingArea?

[ashwin.desi...@gmail.com]

i have a similar implementation for my project. I have a panel to which I
add a canvas (first) and dynamically I add multiple widgets.

I actually don't use z-index ( so i am wrong with my previous comment). All
that I do is I add the canvas before any of my other widgets. I have
enabled domEvents on my widget and capture mouse/ key-board events.

seems to work just fine. Use DevTool (like in chrome) to check how the
widgets are getting rendered. I use absolute positioning on my widgets.

Re: Drag and Drop UI using GWT with Connectors

[ashwin.desi...@gmail.com]

Santosh,

If you have the privilege (depending on your app) to use html5 and css3 as
the min browser requirement, then I would suggest draw the process as as
div and style them as circle using border-radius CSS style.

to draw the connectors, use HTML5 canvas. GWT supports canvas on browsers
which are html5, chrome, opera, firefox (3.6 and above) and IE (9 and
above). This is the technique yahoo also uses with its pipes project

You can implement drag and drop using techniques provided for any gwt
widget.

I have implemented connectors in my project. All you have to do is place
your widgets using absolute positioning on a panel (call it the editor),
draw the connector to a canvas between the widgets and add the canvas to
the editor. You will have to update the position of the widgets &
respective canvas when you drag any of your process widgets.


Regards
Ashwin

Re: Pb with activity and events (using gin)

[ashwin.desi...@gmail.com]

check if the instance of EventBus is the same. I know you have declared it
as eagerSingleton in your GIN configuration. But do a quick log to see if
the instances are the same.

I remember encountering a similar issue wherein I used to have a new
instance of the EventBus getting injected even though I had a similar
configuration as yours. In order to fix the problem I had to do the
following

1. define a provider

public static class EventBusProvider implements Provider {
 private static EventBus bus = null;

/* (non-Javadoc)
 * @see com.google.inject.Provider#get()
 */
@Override
public EventBus get() {
 if(null == bus)
bus = new SimpleEventBus();
 return bus;
}
 }

2. bind

bind(EventBus.class).toProvider(EventBusProvider.class).in(Singleton.class);

Re: How to add absolute panel to celltable column

[ashwin.desi...@gmail.com]

Doc,

You cannot add Widgets directly to a CellTable. You will have to write a
custom implementation by extending one of the AbstractCell Types.

Is there a reason why you need to place a Panel inside a CellTable? If you
are using a table to place widgets either use Grid or FlexGrid. CellTable
is for a different purpose.

Re: datagrid body is disappeared!! height is zero!!

[ashwin.desi...@gmail.com]

do you place your grid directly on the layoutPanel or is it inside other
panels like HTMLPanel etc?

I have had similar issues with loosing the size of the panel, In my case
since I was using absolute positioning, I forced position of my grid on
code to over come the issue.
myGrid.getElement().getStyle().setPosition(Position.ABSOLUTE);

Ashwin

Re: datagrid body is disappeared!! height is zero!!

[ashwin.desi...@gmail.com]

datagrid inside a flex table would not invoke the resize of the grid. Add a
resizelayoutPanel inside your dockLayout, override the resize method and
set the height of the grid.

Re: Canvas dynamical size?

[ashwin.desi...@gmail.com]

drop your canvas inside a ResizeLayoutPanel. This way onResize event you
can adjust the width and height of the canvas.

Re: How to remove drawn elements on the canvas?

[ashwin.desi...@gmail.com]

easiest way to clear a canvas is to use the context clearRect function and
pass the canvas co-ordinate space width & height. This would clear the
entire canvas. And you can redraw the shapes you want to remain on screen.

You can also clear portion of a screen, using the above function by passing
the position and size of the ellipse you draw but if there are multiple
shapes in that position then they would also get erased, you will have to
manage redrawing them.

check out the canvas sample in gwt-examples, it gives a very good demo of
how to use front and back canvas for complex rendering. Using this
technique gives you smooth graphics and also better performance.
