Re: attach listeners/handlers to widget, then do some DOM-stuff - listeners gone?
paste some code to enable more valid answer ;) ... but probably the matter is the fragment below then i attach the whole thing to a div. everything works except the handlers - they simply are never called. if you create a panel (and some widget in its hierarchy) an then attach the panel's element to do DOM with use of plain DOM methods the domHandlers will never be inited (or sinked in gwt-dialekt ;)) - look at onAttach and addDomHandler methods source of widget for more :). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: future of gwt who use gwt
hi thomas, thanks for link to infoq article about dart - so... it seems my guess is possibly right :) - but it's long long way ahead. as to mentioned issue with hashmap - i find it feature rather than problem. and that case is even not java-javascript but ie specific implementation issue. and as to gwt - since this is gwt group - i liked very much the idea of cross-compilation and possibility of maintaining big client side application in java. although it was gwt where i came across it the first time. but than i was not sure about it should try to mimic common java libraries. maybe sticking only to java raw language but with browser specific libriries would be a better solution? libraries that vastly utilize something like JavaScriptObject class in current implementation? maybe the wrong business policy was to target with gwt at existing java developers rather than motivate existing javascript developers to learn java :)? but no tool is perfect - especially from its begining - and imporovements are natural (notice java collections). gwt is still young, and java at its age was imho less convincing technology. if it is not due any legal/licensing strategy than i would stick to java in gwt... if i were gooogle ;). as to mysql - nice to see it on app engine - but this fact does not undermine the possibility of willingness to became independent from oracle owned technology. since mysql community server is open source and GPL licensed, google is no way dependent on oracle in that case. situation with java is quite different, and as i remember some time ago microsoft tried to make its own java, what has been effectively stopped by sun's sue and trial, utlimately resulting in birth of c# :). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: jquery?
hi, main gwt strong point is maintainability, team work support, and refactoring support which comes from java and java tools (and are not specific to gwt) and are not available in javascript and not possible be available in javascript. javascript is extremely flexible and powerful scripting language - but it is scripting language and becomes a nightmare to maintain large scale application or written by team especially by team with big rotation. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: future of gwt who use gwt
I still don't understand the need for dart. if it would be cross-compiled so where is the advantage over gwt? in gwt we have the language that we allready know and tools that were worked out over years. if it will be incorporated into browser as virtual machine than just why not to incorporate the jvm? licensing issues? and another thing - javascript is extremely powerful scripting language. (as far as it is used for scripting - max 300 lines of code it's flexibility is a real power. when comes to maintaining bigger apps this flexibility occurs to be serious flaw, but it the place where gwt enters the play. as i look closer at DART i start to suspect that probably it is not to replace javascript but to replace java (and so avoid dependence to oracle) but do they think they can provide something better than java which gained its maturity over years? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JSNI - interactive chart
it seems that it is not possible to write iframe's content directly in
html.
you can add it programatically which seems even more convenient (but i
wanted to avoid it do to some inconsistency between browser as to when
cotnentDocument of an iframe becames available to code - there can
happen some delay in some browser and onload event is called event if
this iframe does not load any remote content.)
so with this precaution here's the code:
static class YourChart extends Widget {
private static final String API_URL = http://ajax.googleapis.com/
ajax/static/modules/gviz/1.0/chart.js;
private HandlerRegistration handlerRegistration;
public YourChart(JSONObject userConf) {
this(userConf.toString());
}
public YourChart(final String userConf) {
final IFrameElement elem =
Document.get().createIFrameElement();
setElement(elem);
if(elem.getContentDocument() == null ||
elem.getContentDocument().getBody() == null){
handlerRegistration = addDomHandler(new LoadHandler(){
@Override
public void onLoad(LoadEvent event) {
initFrame(elem, userConf);
}
}, LoadEvent.getType());
}
else {
initFrame(elem, userConf);
}
}
private void initFrame(IFrameElement elem, String userConf) {
if(handlerRegistration != null){
handlerRegistration.removeHandler();
handlerRegistration = null;
}
Document cDoc = elem.getContentDocument();
BodyElement body = cDoc.getBody();
ScriptElement script = cDoc.createScriptElement(API_URL);
script.setInnerText(userConf);

Re: Global Event Bus ?
If you want to pass objects between to separately compiled gwt modules via javascript it can only be object that extend JavaScriptObject or primitives. but these can also be your custom overlay objects defined on both sides. for example when module A knows about com.google.gwt.core.client.JsDate and module B knows it either they can pass this object over javascript and overlay it properly as JsDate extends JavaScriptObject, but it is not valid as to plain java objects as they are (or most possibly are) differently compiled on both sides. If you need to share a plain java objects you can make a JavaScript wrapper over it and pass the wrapper js object to another module which can treat it as overlay object - but as you see it is rather a emergency hack than the solution to be use extensively :). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Full page in GWT or just parts?
@Uemit you can write one module to be used in all pages and use code splitting feature to download only what is needed by the particular page. i do that this way. another habit i worked out over years using gwt is to use onModuleLoad method only to register js callbacks. how does the module behave on particular page is then scripted in javascript. however i had to slightly enhance bootstraping script :). generally my pattern is to write whole client logic with gwt (using code splitting and merging modules as much as possible) an then slighlty script it on page to customize its behaviour. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Custom UIBinder Widget, problem expecting only widgets
hi, as far as gwt 2.1. HTMLPanel was treated somohow special by uibinder. (i'm not sure if it hasn't changed in newer versions) normally a widget in ui binder could contain text or html when implemented hasText and hasHTML interfaces. then the content of the node in ui.xml was parsed as text or html. however it was not allowed to contain subwidgets. on the other hand side if a widget implemented hasWidgets interface (so it was a panel :)) it contents in ui.xml has been parsed as widgets to be added to that panel. but HTMLPanel had its own dedicated parser in uibinder: com.google.gwt.uibinder.elementparsers.HTMLPanelParser, which was aware of how to parse both widgets-markup and plain-html. but widgets which inherited from HTMLParser has not been handled by that parser. but coming back to your particular example :) - if yuo only need a html markup (not widgets) inside your widget, do not inherit from HTMLPanel but use HTML widget instead, or Composite and implement hasHTML. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

If you work with spring you probably have a spring controller that extends RemoteServiceServlet implementation.

Re: Using Spring servlets in GWT web apps
as to gwt-rpc simply make your RemoteServiceServlet implementation also implement Spring's Controller interface. The rest goes straightforward. Simply call doPost in your handleRequest implementation and return null (no ModelAndView needed as doPost from RemoteServiceServlet writes all needed directly into response). for example see: http://code.google.com/p/google-web-toolkit-incubator/wiki/IntegratingWithSpring (however the explanation (in comment) why to return null from handleRequest seems to be incorrect for me) as to other than rpc i simply used to paste module script tag into the view (jsp or velocity) :). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

public static interface UI {
Label getLabel();
TextBox getTextField();
Button getSaveButton();
}

@UiTemplate(your.package.SomeWidget.ui.xml)

Re: JQuery like animation
1. But Animation class in gwt seems to be quite handy. All you need is
bunch of custom interpolation functions. But these are easy to be
taken from MooTools (i did take se below :)) - (easing functions in
jquery behave slightly different so simple rewriting it in java drops
off).

find missing in gwt is support for dom-programming and lack of built-
in selector engine. But I agree with Guy that jquery-like syntax is
not necessarily an advantage :)

Re: use ui:text from
not exactly,
ui:name and ui:description
are for messages that uibinder generates from templates (e.g.: the
default set messages - the other you should provide anyway as files).
the proper how-to is in the link to docs you gave above.
ui:text is used when you have messages in resources that you expose to
uibinder template. (which is for example what i prefer to do)
than you us eit like this:
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
ui:with field='msg'
type='com.tomaszgawel.client.YourWidget.Messages'/
g:HTMLPanel
span
ui:text from={msg.hello}/
/spans
g:InlineLabel text={msg.world} /
/g:HTMLPanel
/ui:UiBinder
in java you have sth like that:
public class YourWidget extends Composite {
//messages interface does not need to extend any of
com.google.gwt.i18n.client.* iterfaces but it probably will ;)
interface Messages extends ConstantsWithLookup {
String world();
String hello();
}
@UiField Messages msg; //messages must be ui:field - if you allready
have an instance of messages use @UiField(provided = true)
that's all :)

Re: use ui:text from
but to the original question ;)
you don,t need ui:text markup at all :).
ui:text element has been introduced because you could not use
{messages.messageKey} in plain text not as attribute. as title is an
attribute it is not needed in that case.
just write:
span title={msg.yourTitleMessage}ui:text from={msg.someText} /

Re: Create Canvas widget from CanvasElement
i suppose it's a bug . in majority of widgets constructor with Element
argument is protected.
even a comment in source code of canvas it should be protected not
private:
/**
* Protected constructor. Use {@link #createIfSupported()} to create
a Canvas.
*/
private Canvas(CanvasElement element) {
setElement(element);
}
i think you should raise the issue in gwt-contributors group.

Re: After using Context menu, how to trigger the browsers default one? (on, say, an image)
unregistering the ContextMenuHandler does not work?
I assume you have sth like this:
class YourWidget extends Composite implements ContextMenuHandler {
HandlerRegistration registration;
public YourWidget(){
final HTML html =
new HTML(divRight-click here please
;)/div);
Button setCustomMenuButton = new Button(Set Custom Menu);
Button setNativeMenuButton = new Button(Set Native Menu);
setCustomMenuButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
registration = addDomHandler(YourWidget.this,
ContextMenuEvent.getType());
}
});
setNativeMenuButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
registration.removeHandler();
}
});
FlowPanel mainPanel = new FlowPanel();
initWidget(mainPanel);
mainPanel.add(html);
mainPanel.add(setCustomMenuButton);
mainPanel.add(setNativeMenuButton);
}
@Override
public void onContextMenu(ContextMenuEvent event) {
final int x = event.getNativeEvent().getClientX() +
Window.getScrollLeft();
final int y = event.getNativeEvent().getClientY() +
Window.getScrollTop();
final PopupPanel popup = new PopupPanel(true, true);
popup.add(new HTML(my context menu));
popup.setPopupPositionAndShow(new PositionCallback() {
@Override
public void setPosition(int offsetWidth,
int offsetHeight) {
popup.setPopupPosition(x, y);
}
});
}
}

Re: Declare an array of panels in UiBinder
Assuming you do not use FocusPanel in other cases in this Widget just
anototate addSlot with @UiFactory and return newly created slot from
it:
@UiFactory FocusPanel void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
return fp;
}
this will cause uibinder to call this method instead of FocusPanel's
constructor.

Re: Declare an array of panels in UiBinder
Sorry i haven't noticed vp is panel not list ;)
so in java you have sth like that:
ListFocusPanel slots;
@UiField FlowPanel slotTargetPanel;
@UiFactory FocusPanel void addSlot() {
FocusPanel slot = new FocusPanel();
slots.add(slot);
return slot;
}
in ui.xml:
!-- your root ui element --
g:HTMLPanel
div
pSome sample html .../p
g:FlowPanel ui:field=slotTargetPanel
g:FocusPanel/
g:FocusPanel/
g:FocusPanel/
/g:FlowPanel
!-- slots will contain now 3 elements --
g:HTMLSome sample widget/g:HTML
/div
/g:HTMLPanel
in fact slotTargetPanel is not needed for that - you could stick
Focuspanels anywhere in your ui file - as you have an uifactory method
for creatign FlowPanels.

Re: Declare an array of panels in UiBinder
Yes, you're right. It's a mistake.

Re: GWT frameworks?
still nobody mentioned gwt-query - which btw is truely a framework. while i dont like it's jquery-like naming convention - i stay impressed with the code itself, especially selector engine ;). as to gxt and smart gwt - it was not sth i was looking for so i abandoned using it. gwt itself is a framework - and while i am not fully convinced to it's swing-like widget/panel architecture (and gxt or smart gwt made it even worse), i got used to it. what i found really missing in gwt was selector engine. moreover, it's fast growing framework, and thus leaving less area for frameworks. pure javascript frameworks in much level originated from a necessity to cover browser differences, and its it's not the case with gwt. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Declare an array of panels in UiBinder
Alex, But if your widgets are to be inserted at runtime what you expect to define in uibinder template? a list or an array? it's not the right place because these are visiual templates, and a visual container for widgets is just a panel (or a div if u use htmlpanel as root container), Have i missed the point? but i don't understand the issue -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Sub-classing UiBinder based Widgets
@Alex, When you extend Composite not Widget/UiObject, you init it with initWidget() not setElement - you cannot provide UI implementations that takes use of existing DOM Nodes in html page. without this exception thera no other differences. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
