Re: Hide Popup panel
You should rather encapsulate your context menu logic in a PopupMenu or
ContextMenu class. Something like this may help:
public class ContextMenu extends PopupPanel {
private final ClickListener closeListener = new ClickListener() {
public void onClick(final Widget sender) {
hide();
}
};
private final MouseListener rolloverListener
= new MouseListenerAdapter() {
public void onMouseEnter(final Widget sender) {
for(final Widget widget : items) {
if(widget == sender) {
widget.addStyleDependantName("Hover");
} else {
widget.removeStyleDependantName("Hover");
}
}
}
};
private final VerticalPanel items = new VerticalPanel();
public ContextMenu() {
super(true, false);
setWidget(items);
addStyleName("ContextMenu");
}
public SourcesClickEvents addItem(final String displayText) {
final Label label = new Label(displayText);
label.setStylePrimaryName("ContextMenu-Item");
label.addClickListener(closeListener);
label.addMouseListener(rolloverListener);
items.add(label);
return label;
}
public void show(final Widget parent, final int x, final int y) {
setPopupPositionAndShow(new PositionCallback() {
public void setPosition(
final int width, final int height) {
int px = parent.getAbsoluteLeft() + x;
int py = parent.getAbsoluteTop() + y;
if(px + width > Window.getClientWidth()) {
px = Window.getClientWidth() - width;
}
if(py + height > Window.getClientHeight()) {
py = Window.getClientHeight() - height;
}
ContextMenu.this.setPosition(px, py);
}
});
}
}
The above class adds Labels with a ClickListener to close the PopupPanel and a
MouseListener to handle rollover (Hover) styles. You can use
addItem("Delete This").addClickListener(new ClickListener() {
public void onClick(Widget sender) {
currentItem.delete();
}
});
to add your actual handling ClickListener to the Labels.
Hope that helps a bit.

Re: Observer pattern on this design, yes or no/how and why?
Hi. I tried your recommendations but there are some errors that I
encounter that I think is related to my project's structure
compatibility with your code. As I said above, my project has two
entrypoints. First entrypoint(com.try.client.Page1.java) contains a
vertical panel that contains three composites. Second entrypoint
(com.try.popup.client.PopUp.java) contains a vertical panel than
contains two composites. (Note: they(entrypoints) are from different
modules, same app.)
Now I need Page1.java's panel's contained composites to become
listeners of PopUp.java's horizontal panel's contained composites. For
example, I click something on PopUp.java, Page1.java would show a
reaction thru its composites that are listeners of PopUp.java's
composite # 2. However, as I followed your instruction, I got this
errror:
First, my CODE:
//On Page1.java's first composite: Page1Compo1.java, I included the
following
//declaration of composite # 2
xx;
//somewhere on the code
buttons.addChangeListener(this);//where "this" pertains to
Page1Compo1
THE ERROR:
No source code is available for type com.xxxzzz.client..java; did
you forget to inherit a required module?
note: .java above is composite # 2 of PopUp.java vertical panel.
It seems I cannot use .java on Page1Compo1.java.. What am I
missing?

That's a good guess, but you have to remember one thing: Javascript's
only number type is equivalent to Java's double. It's been a while
since I've looked at the RPC internals, so things may have changed,
but it has been true that a byte[] would be converted into the
equivalent of a double[], and then serialized.
I'm curious about what you're doing with a byte[] on the client, Axel.
Besides filing an issue to see if the GWT developers want to support
your use case, I'd suggest the following: try sending a double[]
instead of a byte[] by packing 6 bytes into each double. Code like
the following might work.
public static double[] bytesToDoubles(byte[] bytes) {
double[] ret = new double[(bytes.length + 5) / 6];
for (int i = 0, n = r.length; i < n; ++i) {
ret[i] = bytesToDouble(bytes, i * 6);
}
return ret;
}
private static double bytesToDouble(byte[] bytes, int offset) {
if (offset + 5 < bytes.length) {
double highTwo = 4294967296.0 * (bytes[0] << 8 + bytes[1]);
int lowFour = bytes[2] << 24 + bytes[3] << 16 + bytes[4] << 8 + bytes[5];
return highTwo + lowFour;
}
double highTwo = 4294967296.0 * (safeGet(bytes, 0) << 8 + safeGet(bytes, 1));
int lowFour = safeGet(bytes, 2) << 24 + safeGet(bytes, 3) << 16 +
safeGet(bytes, 4) << 8 + safeGet(bytes, 5);
return highTwo + lowFour;
}
private static byte safeGet(byte[] bytes, int index) {
return (index >= bytes.length ? 0 : bytes[index]);
}
I'm in a rush, so I'll leave the unpacking code as an "exercise for
the reader". Note also that, since Java's String is a counted data
type, it might be safe to pack bytes into a String without base64
encoding them first, which would save on bytes, too.

Re: Limits to byte[] size in RPC?
My initial guess is that the array serialization during RPC is packing each byte into its own element in a JSON array. So your 400kB byte array turns into a 409,600 element integer array, which is probably using at least 16 bytes per entry, resulting in a fairly large (several megabyte) footprint in Firefox. Doesn't explain why FF grabs several GB for this, but I think you are using a lot more memory than you expect.

Hide Popup panel
Hi, I've used a pop-up panel to display context menu for tree. I've created a custom menu-item by extending Label and added clicklistener for it. I want to hide the pop-up panel once the item being selected. since the click listener is a separate class I'm not able to get the pop-up panel's reference and hide it. I've the class name. is it possible to get the element by specifying the Id and hide it? I'm not sure how to hide. Please help me in solving it. I'm using GWT 1.4.62 Thanks in Advance !!

Re: PermGen space running out.
This is a fairly common complaint for Tomcat instances, especially older versions, where lots of new classes are being introduced at run time. Basically, something in Tomcat doesn't let go of old class definitions. These old class definitions clog up the PermGen space after multiple webapp deployments (or hosted mode refreshes). I don't know of anything that GWT can or could have done about this, other then perhaps creating fewer classes. Switching to -noserver and using another app server could help. Or if -noserver gives you heartburn, you might be able to hack in a newer version of Tomcat into regular hosted mode. Lastly, I've heard that Jetty is being introduced as a hosted mode option in trunk. I am not aware of any Jetty PermGen complaints. - Isaac On Sat, Nov 15, 2008 at 7:11 PM, Ian Bambury <[EMAIL PROTECTED]> wrote: > This is something I first asked about in version 1.1 in 2006. > If you use RequestBuilder (HTTPRequest back in 1,1) then after a while and a > number of F5s to refresh the hosted mode, Java bombs out with a PermGen > space error. > It doesn't do any good to to increase the Xmx - all that happens is that it > takes longer to fail and longer to recover when you kill it. > I'f fairly sure its a GWT problem because I'm on a different computer, a > different OS, a different version of Eclipse and a different version of > Java, and it still happens. > Has anything happened in the past 2 years? > Ian > > http://examples.roughian.com > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Separate client & server help
You will have at leasr to provide your own serialization policies provider, the default one has some check to the same webapp origin.

Limits to byte[] size in RPC?
Hi, I've been trying to handle binary data with one or more MB in size, passing it through RPC. In Firefox (tested with 3.0.4) I can reproduce what to me seems like a memory leak. No matter how I assemble the byte [] contents: as soon as the size approaches or exceeds ~500kB, Firefox allocates >1GB of memory, bringing my 2GB client machine to swap so heavily I have to kill FF. I tested with different byte[] sizes. 400kB seems to be ok, regardless the contents. 500kB rarely works and 600kB I never managed to get through. Assembling the byte[] before actually calling the RPC works fine. It is the RPC call itself where memory consumption in FF goes up so drastically. My workaround for now is to Base64-encode the byte[] into a String and send that along, decoding it on the server again. This lets me suspect that something may be wrong with the byte[] serialization code. In the hosted Java environment this problem does not occur at all, and I can flawlessly send byte[]s with several MB in size no problem.

Border between VerticalPanel-Panels
hi! what i am searchin for is to add a border between two panels. Just like the upper part is the headliner and beneeth the main part. like: HELLO WORLD - widget widget widget widget widget widget widget widget . .. . So i put into the vertical panel a content panel. The content panel holds all the widgets. His CSS Style is this one: border-top-width: 2px; border-bottom-width: 0px; border-left-width: 0px; border-right-width: 0px; And yeah, i get what i want in GWT hosted mode. But when compiled and seen in firefox/ie it looks ugly. It has a border all around. Only the top border is thicker, the others are all 1px. Why? And do any of you have a better solution on this topic? :) Thanks for readin!
