Loading Plus-One-Button dynamically causes Popup to jump in height
Hi,
I'm trying to add a "Plus-One"-Button dynamically to some popups our webapp
is using. I'm using the following code:
HTML google = new HTML(" annotation=\"none\" href=\"http://somecutomurl.com\";>");
>
> Document doc = Document.get();
> ScriptElement script = doc.createScriptElement();
> script.setSrc("https://apis.google.com/js/plusone.js";);
> script.setType("text/javascript");
> script.setLang("javascript");
> doc.getBody().appendChild(script);
>
> DOM.setStyleAttribute(google.getElement(), "margin", "0 5px 0
> 0");
>
> bottomLine.setCellHorizontalAlignment(google,
> HasHorizontalAlignment.ALIGN_RIGHT);
> bottomLine.setCellVerticalAlignment(google,
> HasVerticalAlignment.ALIGN_MIDDLE);
> bottomLine.add(google);
>
Where bottomLine is a HorizontalPanel which is added to the Popup
afterwards. Adding it to the popup directly doesnt help.
The code itself works, the button is added, BUT the Popup enlarges its size
for a very short second when the button is added and gets back to normal
size afterwards. It kind of shrugs for a very short moment, which is very
annoying.
I tried setting a fixed height and max-height for the surrounding div. And
I tried to use the css "clip" attribute. Both not working. Also I tried
using "AddThis"-JS-Library to add the button, same effect.
Does anyone has any idea how I can make this work? I'm sure it can be done,
I saw apps doing exactly the same ...
Thanks!

Re: How to load an external JS-file without calling a function in there
Hi Guys,
thanks for the input!
Finally I figured it out using the phenomenal writeCapture-library
(see: https://github.com/iamnoah/writeCapture/wiki). I linked it from
my module.gwt.xml-file and wrote a simple native method:
public static native void domWrite(String div, String src) /*-{
$wnd.writeCapture.html(div, src, function() {
});
}-*/;
And it works perfectly well!
Regards, Tom

How to load an external JS-file without calling a function in there
Hi,
I'm trying to dynamically add advertisement to our page. Our
advertisement-partner provides us a script which we have to include
like this:
http://www.somesource.com/
output.js?id=123">
The output.js just contains one line of code like this:
document.write("some html");
I have no idea how I can add this JS to the page and make it
execute ... I tried just adding it as a HTML-Widget, which correctly
adds the code, but it isnt executed. Also the ScriptInjection doesnt
help, because I need the code somewhere in the and not in
.
I'm happy for any help!
Tom

Re: 2 Modules in 1 GWT-App, both starting the onModuleLoad?
So thanks to Colin this is solved. The problem was that I seperated my services into a package called "project.services". all modules are referencing this sources. but one of the services was referring to class of "client.child1". so when the xml contained it couldnt find the sources for that single class ...

Re: 2 Modules in 1 GWT-App, both starting the onModuleLoad?
Yeah that were just typos while "removing details" from my code ... BUT I got it working. Not completely satisfying though, but a first step :) I can compile and run both modules when I change the following in Child2.gwt.xml: the path: to: If I do that I can compile and run and it works fine, but I produce a lot more js-code than necessary. Maybe you have one last idea why it's not working? Thanks you so much for helping me!

Re: 2 Modules in 1 GWT-App, both starting the onModuleLoad?
I can acutally compile child1 without any problems. Its just child2 that messes up. And I really don't know why. I had this as an isolated project before and it worked fine. Then I moved it into the main- project and no I can't compile it no more. This is freakin me out. Seriously!

2 Modules in 1 GWT-App, both starting the onModuleLoad?
Hi, I have a GWT-Project currently containing modules (will be more in the future). To make it tidy I created a "containing" module called "Parent". "Parent" does not have any source, its just a containing module. This is the Parent.gwt.xml: The two modules with actual code are apparently Child1 and Child2. There .gwt.xml-Files are the following: Child1: Child2: The compilation works fine but I get 3 js-folders in my war-folder. I supposed that I just get one, as Im using a containing class. For both modules exist a .html-file referencing to the .js-file created for it. The problem is that when I open the Child2.html-file it tries to load the onModuleLoad()-method of Child1! which crashes the system, as there are divs missing. What am I doing wrong? Im stuck with this for a week now! Please help. Anything is appreciated! Tom -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Me again,
just tried to make the imExpensive-method less complex, but still no
success.
The Request is not cancelled ... What am I doing wrong?
Thanks

Request.cancel doesn't work for me!
Hi,
I'm working on an GWT-App displaying a map with different layers.
Some of those layers are drawn just on request and just for the part
of the map which is currently displayed.
The Problem occurs if a user moves and zooms the map pretty fast, so
that a lot of pictures have to be drawn. This results in quite a time
of waiting when he finally stops. What I tried was to cancel the
request using Request.cancel (the Async Method returns Request instead
of void), but all the pictures are drawn anyway.
How does the Request.cancel-method work? Is it just blocking the
Callback? Or does it actually cancel the running code on server-side?
Maybe the problem is, that the specific method contains mainly one
complex method-call? The specific method-scheme looks like:
public Boolean update() {
int a = 2;
int b = 3;
int x = imExpensive(a,b); // method which needs like 95% of
calculating time
if (x>0) return true;
return false;
}
I suppose that the Request.cancel-method does not cancel a running
method, and stops the method right after imExpensive(). Is that right?
In that case the problem could be solved by making the method
imExpensive less complex, which would be a pretty doable task ...
Thanks a lot!
Tom

Session Managment for more than one GWT-Project
Hi there, I'm writing an GWT-App containing several sub-projects. To keep the App lightweight and easy I created different projects for each subproject linking to each other. I deployed the projects on my Tomcat and it works fine, BUT: As every subprojects has its own server-classes and therefore creates its own session, i cannot recognize an user who logged in on a different page. so my question is: is there any way to tell the apps to share the session managment? or do i have to restructure my whole project again? thanks a lot! tom -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How to merge 2 projects into 1?
Hi all, I created two projects with GWT and Eclipse-Plugin. Because both projects have a completly different client-side code, but also completly the same server-side code, I want to combine them to avoid having the same code twice. What I did was to link the project without the server-side code to the one with the server side code. Eclipse isnt showing any error. But when I compile the project now, GWT says: "No source-code available" for both the XXXService.java und XXXServiceAsync.java. Adding com.XXX.client to the projects XXX.gwt.xml doenst help ... Can anyone tell me how to solve this issue? Thanks a lot! Tom -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Sending mails from GWT-App
Ok i got that.
Now my App tells me that the API package 'mail' or call 'Send()' was
not found. ...
Did I just forget to inherit something, or is it not possible to use
mail command with GWT?
Thanks!

Sending mails from GWT-App
Hi,
I'm trying to send an email from my GWT-App. I found the following
code using google:
protected void sendMessage(String smtpHost, String fromAddress, String
fromName, String to, String subject, String text) {
// Get system properties Properties
props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", smtpHost);
// Get session
Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(fromAddress, fromName));
// Set the to address
message.addRecipient(Message.RecipientType.TO, new
InternetAddress(to));
// Set the subject
message.setSubject(subject);
// Set the content
message.setContent(text, "text/html");
// Send message
Transport.send(message);
}
But I'm getting a "java.lang.AssertionError: null".
I was wondering why I do not have to enter a password for the smtp-
server, and what to enter at String smtpHost, as I have to enter my
Smtp-Host at props.put() again ...
Thanks!
Tom

Re: How to use one service from several GWT-Apps
sorry i meant service. i try to explain the problem more precisely: i got a map. users can, for example, use the app to calculate a route- advise. if the user did so he may want to print the route. but the map is nearly fullscreen, so if he justs prints it like that it looks pretty bad. so what i do is to open a new browser window with a smaller map. and now in this new window the route must be newly calculated, because you cant give a java object to the new window, right? what i want now is that the print page uses the routing servlet of the main app. what i dont want is that the print page needs all the same server code again. but i dont get it working. because if i merge the projects the web.xmls clash. thanks a lot! tom On 23 Jun., 21:47, Blessed Geek wrote: > "service"? > > Printing thro web service that all/any window could call with a single > url?

How to use one service from several GWT-Apps
Hi, I'm currently trying to add some printing functions to a map-software. If the user hits the print-button a new browser-window, which's dimensions fit to a normal sheet of paper, is opened. As the user usually wants to print stuff like a route or so the new window needs to use the same services the main-app does. What I already tried: First I did the printing stuff on its own and tried to merge the projects (map and print). There where some problems because of the web.xml. Then I added another print.html to the map-root-dir and tried to merge the source directly in one project. In this scenario the onModuleLoad()-method of the print.html wasnt fired. Is there a way to let the print-app use its parents-apps services? I'd really like to avoid to have the code twice on my server ... thanks for any advise! tom -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: IE7 does not complete loading pictures
Im just doing the solo entertainer ;)
I got it almost working. I changed the mapPart.setUrl(path) to
DOM.setElementAttribute(mapPart.getElement(), "src", path);, which
leads to a correctly displayed map.
BUT still both IE7 and 8 doenst finish loading. The status bar still
says, 18 elements need to be loaded, and the icon in the tabbar keeps
to be the loading circle all the time.
so if maybe anyone could help me out?
cheers

Re: IE7 does not complete loading pictures
And there actually is a workaround.
If I do add something like "x=12345" to the image-path, it does work.
so i suppose that its some ie7 cache issue, but i really got no idea
what to do about it.
I really do not want to disable caching using the method above!
thanks again!

Re: IE7 does not complete loading pictures
Ah I forgot to mention, that the images which didnt load in the first
place, still dont load if I, for instance, zoom back to those tiles
again. Its like a white whole in the middle of the map then.
thanks!

IE7 does not complete loading pictures
Hello,
I am currently developing a map-service application.
Therefore I have a grid containing the tiles of my map.
I wrote an algorithm which dynamically fills this grid with the number
of needed tiles.
Strange thing is, that the IE7 does not complete the initial loading
of the images, the status bar says that it has to load 18 more
elements, but it never completes this task.
But if I do some action with the map then, like zooming or scrolling,
so that the displayed tiles change, the same algorithm works perfectly
well.
Anyway IE7 and IE8 never fire the image.onload Event.
Here is some code:
public void displayVisibleTiles(VisibleTiles tile, int zoom, int
zoomvalue) {
int countX = (- visibleTiles.getBottomLeftTile()[0] +
visibleTiles.getTopRightTile()[0]+1);
int countY = (visibleTiles.getBottomLeftTile()[1] -
visibleTiles.getTopRightTile()[1]+1);
picGrid.resize(countY, countX);
currentCountX = countX;
currentCountY = countY;
int xCounter = 0;
int yCounter = 0;
int yEnd = (visibleTiles.getTopRightTile()[1]) + countY;
int yStart = (visibleTiles.getTopRightTile()[1]);
for (int y = yStart; y < yEnd; y++)
{
xCounter = 0;
for (int x = (visibleTiles.getBottomLeftTile()[0]); x <
(visibleTiles.getBottomLeftTile()[0]) + countX; x++)
{
Image mapPart = new Image();
if ((y < 0) || (y >= tiles.getImageCount(zoom))
||
(x < 0) || (x >=
tiles.getImageCount(zoom))) {
mapPart = new Image();
mapPart.addLoadHandler(new
LoadHandler(){
@Override
public void onLoad(LoadEvent
event) {
System.out.println("Pic
Loaded!");
}});
mapPart.setUrl("pics/blank.jpg");
}
else {
mapPart = new Image();
mapPart.addLoadHandler(new
LoadHandler(){
@Override
public void
onLoad(LoadEvent event) {
System.out.println("Pic Loaded!");
}});
mapPart.setUrl(folder + zoom +
"/im" + x + "_" +
y + ".jpg");
}
}
picGrid.setWidget(yCounter, xCounter, mapPart,
y, x);
xCounter++;
}
yCounter++;
}
}
Thanks in advance for any advice!

Can't open my GWT-page
Hi, I created a little GWT-Page. But after I upgraded my GWT to 2.X I can't open the page anymore. The browser always says: "Please (re) compile the project, or use hosted mode" (actually it doesn't say that litterally, but you know what I mean :) ). I recompiled the project several times and no compiling erros occur. I'm running WinXP SP3 with GET-Eclipse Plugin. Thanks for any advice! noise -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
