How to create deep copy of list on client side?
Hi, how can I (if possible) best create a deep copy of an ArrayList on the client side? I just need a list that when objects are changed does not reflect the changes to the source list. How could this be done clientside? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: TabLayoutPanel with scroll buttons
I updated the code of Eze for GWT 2.5.
Apparently, the lastScroll trick is no longer needed, and I override the
root insert / delete methods to reduce the number of overrides. There was
also a little bug, using scrollLeftButton.getWidth() in place of
scrollLeftButton.getHeight(), visible when the buttons are not square...
I renamed also some methods to my taste. :-)
There are still some things to improve, as I don't like the buttons to be
over the first tab, but I will look into it later.
Here is my variant:

Unable to log uncaught exceptions with RPC, SerializableThrowable not assignable to IsSerializable
So right, the basics, this is running on GWT2.5.0 / JDK1.6 and set up more
or less as the docs have it set up
*gwt.xml*
and I'm forcing the exception with the following code, just a simple
NullPointException
try {
Level n = null;
n.getName();
} catch (NullPointerException ex) {
//SerializableThrowable st = new SerialiableThrowable();
logger.log(Level.SEVERE, "Null Exception Hit", ex);
}
But for some reason this is thrown when the exception is thrown to the
server
[WARN] remoteLogging: An IncompatibleRemoteServiceException was thrown
while processing this call.
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException: Type
'com.google.gwt.core.client.impl.SerializableThrowable' was not assignable
to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a
custom field serializer. For security purposes, this type will not be
deserialized.
at com.google.gwt.user.server.rpc.RPC.decodeRequest(RPC.java:323)
at
com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:206)
According to the docs on remote server logging this should "just work" and
I don't see why this is getting thrown. It seems to me
SerializableThrowable should by definition be serializable. I know you
have to jump through some hoops to have your own classes be serializable,
but everything I've read says I should be able to toss exceptions back to
the server without issue. Any ideas? It looks like since 2.5.0
serializableThrowable has been moved to
com.google.gwt.core.shared.SerializableThrowable,
but I don't think that's doing it.

Re: Changes Opacity for vertical scrollbar inside 2.4 DataGrid?
DataGrid uses a CustomScrollPanel for its data table. Such panel uses transparent-style native scrollbars, but the resources used (NativeVerticalScrollbar.ResourcesTransparant) are hardcoded in the CustomScrollPanel constructor. I guess you can: - extend the DataGrid to obtain a reference of the inner CustomScrollPanel. See [1] on how to do that; - extend the default NativeVerticalScrollbar.ResourcesTransparant to provide your own style (or use the no-op NativeVerticalScrollbar.Resources to remove any opacity); - in the extended DataGrid constructor, after super(), use the CustomScrollPanel reference to set up a new scrollbar using the method setVerticalScrollbar(...) passing in a new NativeHorizontalScrollbar with your new resources. The same applies for the horizontal scrollbar. Or you can look at the DOM and figure out some hack to obtain the scrollbar container (as you tried).

Changes Opacity for vertical scrollbar inside 2.4 DataGrid?
Can someone please tell how to change the opacity for vertical scrollbar
inside 2.4 DataGrid?
Tried few things but nothing is working...
1)scrollPanel.getElement().getStyle().setOpacity(1);
2) DOM.setElementAttribute(scrollPanel.getElement(), "Opacity", ""+1);
3) scrollPanel.getElement().getStyle().setProperty("filter",
"alpha(opacity=100)");

Repainting a canvas - clear or create new object?
Hi, when a Canvas is often cleared and redrawn (for example during a drag and drop action): would it be better to call ctx.clearRect(0, 0, clientWidth(), clientHeight())? Or just create a new Canvas by Canvas.createIfSupported() and replace the currently drawn canvas by the new one?

Re: Complex JSON and overlay types
You need to decode Message.class.
So instead of:
/AutoBean bean = AutoBeanCodex.decode(factory, Person.class, json);
Do this: /
/ AutoBean bean = AutoBeanCodex.decode(factory,
Message.class,json );/
Take a look here: https://gist.github.com/dozed/912ebc73dbeb43f3a539

Does /this.records[0].names["John"]/ works? If so, there shouldn't
be any problem replacing the "John" with a method argument.

Re: how to deploy a demo program created by GWT glugin for eclipse?
You just copy your GWT project's war folder to $JETTY_HOME/webapps and rename it accordingly. Also rename the copied war folder to something that identify your webapp. For example, $JETTY_HOME/webapps/gwttest1/ myGWTHtmlfile.html Then start jetty and your app should be available at localhost:8080/ gwttest1/myGWTHtmlfile.html If you son't want to have the prefix "gwttest1" then just copy the GWT war folder to $JETTY_HOME/webapps and rename it to 'root', for example $JETTY_HOME/webapps/root/myGWTHtmlfile.html. In this case your app should be available at localhost:8080/myGWTHtmlfile.html For more information: http://wiki.eclipse.org/Jetty/Howto/Deploy_Web_Applications Good luck.

Re: Get mouse position in Canvas on keyPress?
Ok but for a GWT Canvas there is no canvas.getBoundingClientRect() or
similar.
So this would mean I have to constantly update the mouseXY variables within
@UiHandler("canvas")
void onMove(MouseMoveEvent evt) {
x = evt.getRelativeX()...
}
BUT wouldn't this add a big overhead in the long run if I constantly
rewrite the coordinates?
I could of course use some timer to update XY, but this would then again
result in inaccurate coordinates if the keypress comes in the wrong moment.

Re: Get mouse position in Canvas on keyPress?
Missed the part that you want the mouse position in a canvas. Take a look at http://www.html5canvastutorials.com/advanced/html5-canvas-mouse-coordinates/ You could easily transfer this to GWT and on a key event use the current mouse position you have saved in your app by tracking the mouse movement on the canvas element. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
