Re: "gwt-servlet.jar" being deleted at each Eclipse startup after upgrading to gwt 2.0
I found the culprit. The eclipse plugin preferences file explicity names gwt-servlet.jar as a file that it must copy to the web-inf/lib directory. So I assume that SVN (and for me it is Perforce) see that action as an attempted delete as well. I resolved this myself by removing that file from web-inf/lib and just letting the plugin have its way. I tried deleting the offending line from the preferences file, but the plugin insisted on replacing that line on startup. Odd, if an application *insists* on a very specific setting regardless of user intentions or my own preferences, why put the setting in an external preferences file to begin with?

I haven't studied either the Contacts sample or Hupa project, but here's what my PlaceManager is doing: - an HistoryMapper is injected in the ctor and maps history tokens to Place objects, and Place objects to history tokens (I have a bunch of utility classes to compose an HistoryMapper composed of other HistoryMapper instances: using the chain of responsibility pattern, based on prefix matching, etc.) - PlaceManager fires a PlaceChangeEvent whenever a History ValueChangeEvent is fired (i.e. back/forward browser buttons management); it has an explicit navigateTo(Place) method that to set the current Place, fire a PlaceChangeEvent and update the current history token using History.newItem(mapper.stringify(place), false) (see below for details); that way, PlaceManager is the *only* object that ever works with the History class. - presenters *explicitly* register PlaceChangeEvent on the PlaceManager - navigation is "vetoable" (*even* browser-generated navigation, *and* Window.onClosing) to allow for "you haven't saved your changes, do you really want to leave this screen?" scenario; this is done with a vetoable PlaceChangingEvent being dispatched before the PlaceChangeEvent take place (this is why I have an explicit navigateTo method, instead of firing events directly on the EventBus) - Place is just an interface, with no method; you create classes implementing it (such as ContactsListPlace and ContactsDetailsPlace, I even have enums that implement the interface) and generally use "instanceof" in your PlaceChangingHandler and PlaceChangeHandler impls. You can have a ContactsPlace as the base class for ContactsListPlace and ContactsDetailsPlace to setup the "screen" for the "contacts module" (this correspond to a "tab" in our app), whichever exact "screen" from this module is "invoked" (this is very useful for the "main presenter" to highlight/select the appropriate tab, for instance; then the tab widget uses the more "precise" ContactsListPlace and ContactsDetailsPlace to choose which presenter/widget to use) Everything is explicit, and the mapping of history tokens to Place objects is completely disconnected from the presenters (they only deal with Place objects); and using the utility classes, this mapping is modular and easier to maintain (for instance, we have one HistoryMapper per "module" --which can be composed of other mappers already-- and compose them using prefix matching in a global mapper to be passed to the PlaceManager. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Get the real path of application
You will get the real path from "HttpServletRequest". Use

Re: Customizing RichTextArea with insertHtml in GWT 2.0
Hi Tevis, If u want customize your text area you should use RichTextArea and a toolbar for changing the font,color , creating a link etc. This tool bar is freely available in http://gwt.google.com/samples/Showcase/Showcase.html#CwRichText. Note that the code is available in gwt samples.

Re: Customizing RichTextArea with insertHtml in GWT 2.0
Hey thanks,
I've seen that post which was what turned me on to RichTextToolbar
when i started to research this a couple of days ago. It looks great
and will definitely be the inspiration for how i create mine. The
problem is i want to do custom functionality that the raw Formatter
object doesn't supply. (custom youtube and embeding and a few more
things) which i can do just perfectly with insertHTML. The problem
is, i want to grab the text that the user has highlighted so that i
can use it when i insert the custom html but the API doesnt seem to
expose it. The custom RichTextToolbar implementation just calls
methods on RichTextArea and never actual seem to touch the selected
text directly. It just calls things like
RichTextArea.Formatter.createLink... which hands wrapping the selected
text internally.
I just wrote a hack work around for the time being so that i can
progress to other work but i'm still convinced that a getSelectedText
method exists somewhere. If it doesnt, it certainly should.
Here's the workaround that i just came up with:
private String crazyGetSelectedText(RichTextArea
rta) {
final String MARKER = "http://trevsmarker.com";;
rta.getFormatter().createLink(MARKER);
String withMarker = rta.getHTML();
int markerIndex = withMarker.indexOf(MARKER);
int beginIndex = withMarker.indexOf('>',
markerIndex)+1;
int endIndex = withMarker.indexOf('<',
beginIndex);
String selected =
withMarker.substring(beginIndex, endIndex);
rta.getFormatter().removeLink();
return selected;
}
That seems to get the job done but how horribly inefficient is that
solution?

addDomHandler method is protected, how to add DomHandler without overriding widget ?
My objective is allow moving, rotating and resizing any GWT widget with fingers... I have successfully created and instanciated a new DOMImplIphone to manage touch and gesture events. I have overrided a widget (button or panel) to add dedicated add<>Handler method. Those methods are calling the addDomHandler method. I can now successfully move, resize and rotate this specific overrided widget ! Now, i would like to have a "generic widget wrapper" that allow resizing the wrapped widget. Idea was to create a WidgetWrapper(Widget widget) and add in this wrapped all the methods to set handlers. My pb is that the addDomHandler is protected... so i can not wrap my widget !! Any solution to avoid overriding all the widgets that i want to move/ resize ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: "gwt-servlet.jar" being deleted at each Eclipse startup after upgrading to gwt 2.0
Amazingly, you're right. The solution is to ignore the message, *don't* revert your files back, and restart Eclipse again. The plugin deletes the files the first time, then recreates them the second... and since the new files are identical to the old, svn is happy.

Re: gwt 2.0 jdo / jpa enhanced classes in App engine / Data Nucleus used for GWT-RPC calls to client side
Skip JDO/JPA and use something like http://code.google.com/p/objectify-appengine/ which uses *real* POJOs for your domain objects. They will transfer through GWT-RPC just fine.

Re: SuggestBox with server side update and UrlFetch Service
Okay, I figured it out myself, again it had to do with sloppy coding.
When getting the JSONArray I was assuming the the second element in
name would be the "Result" I want to
retrieve. This was the case running in development but not the case
when I deployed it. So instead I will just retrieve by "Result".

Easiest method to add a class to the bottom of a TagPanel?
I wish to dynamically change a class in the bottom part of a Tag panel. (the bit that normally has "gwt-TabPanelBottom"). Any ideas? I tried navigating the dom but got rather confused. Basically I want to change the background behind it, without altering the background of a header. And I want to do it ver a class so the images can be specified outside the code. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: addDomHandler method is protected, how to add DomHandler without overriding widget ?
Thank you for your answer but it is not exactly what i woulk like...
The events should be the new events i have created and registered with
my DomImpl. (TouchStartEvent, TouchEndEvent)..and not HasMoveEvent,
HasResizeEvents...
What i would like to do:
It seems that i really need to do the widget.addDomHandler call...
public class TouchWidgetWrapper extends SimplePanel (or Composite) {
protected Widget widget;
public TouchWidgetWrapper(Widget widget) {
add(widget);
this.widget = widget;
this.setStyleName("noSelect");
}
public HandlerRegistration addTouchStartHandler(TouchStartHandler
handler) {
return widget.addDomHandler(handler, TouchStartEvent.getType
()); //not possible addDomHandler is protected)...
}
public HandlerRegistration addTouchMoveHandler(TouchMoveHandler
handler) {
return widget.addDomHandler(handler, TouchMoveEvent.getType());
}
public HandlerRegistration addTouchEndHandler(TouchEndHandler
handler) {
return widget.addDomHandler(handler, TouchEndEvent.getType());
}
public HandlerRegistration addTouchCancelHandler(TouchCancelHandler
handler) {
return widget.addDomHandler(handler, TouchCancelEvent.getType());
}
public HandlerRegistration addGestureStartHandler(GestureStartHandler
handler) {
return widget.addDomHandler(handler, GestureStartEvent.getType
());
}
public HandlerRegistration addGestureEndHandler(GestureEndHandler
handler) {
return addDomHandler(handler, GestureEndEvent.getType());
}
public HandlerRegistration addGestureChangeHandler
(GestureChangeHandler handler) {
return widget.addDomHandler(handler, GestureChangeEvent.getType
());
}
}
//TouchStartEvent:
public class TouchStartEvent extends DomEvent {
private static final Type TYPE = new
Type("touchstart", new TouchStartEvent());
public static Type getType() {
return TYPE;
}
protected TouchStartEvent() {
}
@Override
public final Type getAssociatedType() {
return TYPE;
}
@Override
protected void dispatch(TouchStartHandler handler) {
handler.onTouchStart(this);
}
}
//TouchStartHandler:
public interface TouchStartHandler extends EventHandler {
void onTouchStart(TouchStartEvent event);
}
HasTouchStartHandlers:
public interface HasTouchStartHandlers extends HasHandlers {
public HandlerRegistration addTouchStartHandler(TouchStartHandler
handler);
}
