Overlay Instantiation from within JavaScript
I have a simple JavaScript overlay class.

PopupPanel Align Right
Is it possible to align a PopupPanel with the right side of the window or the right side of a panel? I know that it could be done by getting the size of the window and setting the position of the PopupPanel based on that. However, if window is re-sized, the popup won't move with the re-size. This would be a simple "align: right" style attribute in CSS, but it gets ignored every time that I try to use it with a PopupPanel.

Set Position Relative to Right Side of a Panel
I would like to position a Popup or a Label, or even just an Image relative the right side of each of the panel in a HorizontalSplitPanel. Something like what I have drawn below where '*' is the Popup, Label, or Image. I can't get the position of the object so that it will stay with the right side. I know it can't be that difficult, but I'm at a bit of a loss. - | * | * | | | | | | | | | | | | | - --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: RPC error with Map
Sounds like famous last words to me. :) things are working for me, despite the warning. I have the following suppress line in my gwt.xml file. Out of curiosity more than anything, I would like to understand why this error occurs. I've read issue 2862 (http://code.google.com/p/ google-web-toolkit/issues/detail?id=2862), but I don't quite follow. How come all of the other maps go through fine. String by themselves go through. Collections of Strings go through. Why doesn't a Map with Strings as the values go through? I don't even have to put anything into the map.

Re: Gwt + Openlayers + Beyond (but no so far)
Try one of these modules:

http://www.peterfranza.com/projects/gwt-openlayers-bindings/
Let us know which you find best (Neither seem to have great
documentation).

Re: GWT and openlayers : ERROR
A more detailed answer is here:
https://sourceforge.net/tracker/index.php?func=detail&aid=2035864&group_id=205333&atid=993218
To make to fix yourself, you'll need to get the source for GWT-
OpenLayers. How to do that is described here:
http://sourceforge.net/cvs/?group_id=205333
If you're using Eclipse, you can do an "Import" and select the "CVS-
>Projects from CVS" option. Enter the information found in the link
above. Then, all you have to do is add the protected constructor to
the JSObject class as described in the first link above, and create a
new jar.
I've send a request for a new release to be created. I'm not sure
when that will happen though.
Hope that is a little more clear?

Re: GWT and openlayers : ERROR
I had the same problem. I think it was introduced with GWT 1.5. I
had to download the OpenLayers source and add an empty protected
constructor to the JSObject class:
protected JSObject() {}
Everything seems to work fine after that.

Re: Getting User Input from Input Field
I tried "elem.getAttribute("value")". It unfortunately, didn't change
the behavior.
As for using a text box, this example is a dumbed down version of what
I'm doing. The real application is integrating GWT as part of other
(non-GWT) JavaScripts. The other JavaScripts are inserting data into
an input field. I would like to read those values from the GWT part
of the application. If there is a better way, I'm open to
suggestions. I merely added the HTML element to better simulate the
situation I'm in. I guess the sample code isn't a good example. I
don't have a direct access to the Element object. I would have to get
element by ID (the commented out lines in my example).
I guess, the real question is how do I get non-GWT javascripts to talk
to GWT?
I'm also curious to why it works in IE and hosted mode but not other
browsers. I thought GWT was (thankfully) suppose to take care of
browser differences.
Thanks

Re: Getting User Input from Input Field
Thanks. getElementProperty is what I needed.
The input was created this way to better show the situation. The GWT
components are part of a web page that has other (non-GWT) JavaScripts
running in it. The other JavaScripts are writting to an input field.
The user can also enter data in these fields. I was trying to get the
GWT scripts to read this data.
Thanks again.

Getting User Input from Input Field
I'm trying to get the text entered by a user in an "input" field. It
works in IE and in Hosted Mode, but not in Firefox or Chrome. I'm
using DOM.getElementAttribute to read the text. When it doesn't work,
all I get is an empty string. I've made simple test case by modifying
the template code generated by the applicationCreator. Below are the
code snippets. Any ideas on how to get this to work?
.
.
.
final HTML inputHTML = new HTML("");
vPanel.add(inputHTML);
.
.
.
button.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
String val = "NULL";
try
{
//com.google.gwt.user.client.Element elem =
DOM.getElementById("input1");
com.google.gwt.user.client.Element elem =
DOM.getChild(inputHTML.getElement(), 0);
if (elem != null)
val = DOM.getElementAttribute(elem, "value");
}
catch (Exception ex)
{
val = "ERROR: " + ex.getMessage();
}
vPanel.add(new HTML("VALUE: " + val));
}
});
