Can I copy an image to avoid re-requesting from url?
Hi, I have written a GWT client that among other things requests images that are generated server-side. To conserve bandwith and server CPU, I would like to cache the images in an url - image map. To do that properly, I would need to be able to copy an image as in final Image myImage = new Image(cache.get(url)); Is this possible? Regards, Anders S.

Making the back button go even further back in history?
Hi, I have this unusual problem. I have a form page that redirects to a results page that auto- redirects to my GWT application page. Now, if the user presses the browser Back button, he goes back to the auto-redirect page, which is not what he would expect - he wants to get to the form page, so TWO steps backwards. Is there any way to make that happen? Regards, Anders -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

The -draftCompile flag: Impact on compilation speed small, sometimes negative
Hi there, I made a few measurements on the -draftCompile flag. Remember that it was supposed to make compilation faster: With -draftCompile: Project 1: 57.614s Project 2: 49.975s Project 3: 38.656s Total: ~146 seconds Without it: Project 1: 51.889s Project 2: 59.473s Project 3: 41.833s Total: ~153 seconds I know these are only three data points, but there seems to be no clear advantage to using the flag in terms of compilation speed. Seven seconds saved out of 153 is hardly worth it. Worse: One project even got slower compiles from using the flag. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Geting a stack trace?
Hi,
I have implemented a trappable command, that will show a popup in
case of an uncaught exception during its execution. It seems that a
stack trace is not available using the normal Java methods - at least
not when run in a browser. Any suggestions?
Here's the code.

/**
* Execute this command, report any exception in a popup panel.

panel.

try {
cmd.executeWithCatch();
} catch (final Throwable t) {
final PopupPanel panel = new PopupPanel(true);
panel.setWidget(makeWidget(t));
panel.center();
}
}
/**
* Make a normal command trappable.
*
* @param cmd The command to make trappable.
* @return A trappable wrapper for cmd.
*/
public static Command makeTrappable(final Command cmd) {
return new TrappableCommand() {
@Override
protected void executeWithCatch() {
cmd.execute();
}};
}
private static Widget makeWidget(final Throwable t) {
final VerticalPanel host = new VerticalPanel();
host.add(LabelFactory.makeNewLabelBiggest(Exception
caught));
addThrowable(t, host);
return host;}
private static void addThrowable(final Throwable t, final
VerticalPanel host) {
host.add(new Label(Class: + t.getClass().getName()));
host.add(new Label(Message:));
addStringWithLinebreaks(host, t.getMessage());
host.add(new Label(Stacktrace:));
addWithLinebreaks(host, t.getStackTrace());
if (t.getCause() != null) {
host.add(LabelFactory.makeNewLabelBig(Caused by));
addThrowable(t.getCause(), host);
} else {
host.add(new Label(No cause));
}

Yup. Took me a while to figure out.
Now I usually use a common interface like this for all my widget-
making code:
interface WidgetProvider {
Widget createNewWidget();
}
This both ensures that I can introduce on-demand creation of objects
if I need it, and that I can create several instances configured in
identical ways by using this method, provided that it is implemented
in a sensible way.

Re: How to tell if an image is done loading (or failed) for sure, given LoadListener is broken on IE?
Anyway...
Using the tip from the issues list (set URL in deferred command) I can
get reliable execution of LoadListener on IE, as well as Safari and
FF.
Now I have a different problem.
In IE it seems that an image has dimensions 0 x 0 until visible, even
if it is loaded. Is there any way around that?
Here is my test program. On Safari and FF I get size 120,90 for the
image, even before it is made visible. In IE size is 0,0 until made
visible.
final RootPanel rootPanel = RootPanel.get(jobList);
final String url =
http://arstechnica.com/mt-static/plugins/ArsTheme/style/themes/
light/images/logo.png;
final Image image = new Image();
final Label l = new Label(Not loaded yet, size + image.getWidth
() + , + image.getHeight());
rootPanel.add(l);
image.setVisible(false);
LoadListener ll = new LoadListener() {
public void onError(Widget sender) {
l.setText(Failed);
}
public void onLoad(Widget sender) {
l.setText(Success, size + image.getWidth() + , +
image.getHeight());
rootPanel.add(new Button(Make visible, new
ClickListener() {
public void onClick(Widget sender) {
image.setVisible(true);
l.setText(Visible, size +
image.getWidth() + , +
image.getHeight());
}}));
}
};
image.addLoadListener(ll);
rootPanel.add(image);
DeferredCommand.addCommand(new Command(){
public void execute() {
image.setUrl(url);
}
});

Help me make my own Jar file with an interface, that can be shared between the client and a Java-based server

Hi, I have searched the archives and the web, and all I could find was 1) Drag/drop projects that were only related to widgets. 2) Some discussions, all at least a year old, concluding that it was either hard and non-standards compliant, or impossible. Any progress? Regards Anders --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How do I make a pretty, easy to use button without making custom images for each one?
Hi, I would like to make a button that looks like this: (|| text ||) ...where ( is a rounded left-end of the button, ) is a rounded right- end of the button, || is a background and text can be specified e.g. at creation. Thus, all buttons of this type would share the same style, but not the same text on the face of it. Examples: (|| OK ||) (|| My very long button text ||) How would I go about this, without having to generate each individual button as an image in my drawing program?

Re: So I want to put some shared classes in a Jar file...
Hi,
Creating a module jar file is quite simple, you just need the following
things:
Thank you for your help, but I was looking for something a little more
step-by-step.
I have since figured out how to do it. Here is my tutorial that I
wrote for internal use in my company.
Making a GWT module, the GWT flavor of a Jar file
The following tutorial assumes that you are using Eclipse.
Step 1: Generate the host project for the module
The first step is to generate a project that can host the code. As
part of the process, we will also generate an Ant build file that can
make the Jar file that contains the module.
You must have GWT installed in order for this to work at all.
First you must create the project:
The command shown below creates an Eclipse project and an Ant
buildfile that contains the project angeSharedGwtComponents. The
files are written to the directory ./SharedComponents. You can name
the project pretty much whatever you like, within reason (try to stick
to US ASCII letters, no spaces or odd chars - remember file system
semantics differ).
projectCreator -ant angeSharedGwtComponents -eclipse
angeSharedGwtComponents -out SharedComponents
Step 2: Create a host application for your code
You have a project. Now you need to generate a default application
that you can add your code to.
The command below creates an application package structure that has
its root in the dk.ange.client package. The main Java class is named
dk.ange.client.SharedComponents. The application is stores in the
directory SharedComponents.
NB: Note that the last node in the package structure MUST be called
'client'. The applicationCreator program enforces this, and will give
you a warning, so there is no risk that you do it wrong.
applicationCreator -eclipse angeSharedGwtComponents
dk.ange.client.SharedComponents -out SharedComponents
Step 3: Clean up the entry point class
The main class generated by the applicationCreator command contains a
lot of demonstration code. You should slim it down to just this:
package dk.ange.client;
import com.google.gwt.core.client.EntryPoint;
/**
* Entry point classes define codeonModuleLoad()/code.
*/
public class SharedComponents implements EntryPoint {
/**
* This is the entry point method.
*/
public void onModuleLoad() {
// Any common init code goes here
}
}
Step 4: Add your code to the project
This is reatively simple, except for the fact that there are some
restrictions on package naming. All packages MUST be rooted in the
package that contains the entry point/main class for the project.
Hence, if your main class is named dk.ange.client.SharedComponents,
all code must reside in packages whose name starts with
dk.ange.client, e.g. dk.ange.client.ui.buttons.
Step 5: Build a Jar file with Ant
Once you code is added, tested and compiled, you can use the Ant build
file generated earlier to package the module in a Jar.
In this example the project is called angeSharedGwtComponents, and it
is stored in the directory ./SharedComponents
cd SharedComponents
ant -f angeSharedGwtComponents.ant.xml package
Step 6: Add the Jar file to the GWT project you want to use it in
Copy the file to your project using Eclipse. A simple copy/paste works
fine, at least on the Mac.
Add it to the build path by right clicking the project, and then
selecting Properties - Java Build Path - Add JARs...
Step 7: (final step) Add the module to the GWT XML file for the target
project
Open the gwt.xml file for the project you just added the Jar file to.
If the entry point/main class is named
dk.ange.myproject.client.MainModule, the gwt.xml file is named
MainModule.gwt.xml, and resides in the dk.ange.myproject package.
Add an import reference to the Jar file, e.g.
inherits name='dk.ange.SharedComponents'/

I guess I will go with the straight image solution for now. It's feasible, as all the users will use uniform configurations (browser, screen size, resolution), so it's probably not worth the hassle to do a more generic solution.

So I want to put some shared classes in a Jar file...
Hi, I have a project projectone that looks roughly like this: com.company.gwt.projectone It contains some classes that I would like to re-use in another project/module projecttwo. I assume that the best way to do that, would be to extract those classes, and put them in a Jar file. The classes are currently here: com.company.gwt.projectone.client.reuseableclasses How do I proceed? I'm using Eclipse, but am no stranger to the command line in general. However, I have never had to make a Jar file before, even in generic Java. Do I e.g. need to create a new GWT project from scratch, and move the classes there? They reference GWT specific classes... How do I make a Jar file, that is structured correctly? Anders --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

You can add a dummy Label object into right most side, and setCellWidth of
label widget to 100%.
A good suggestion, but it doesn't fix the real problem.
The table is a ScrollTable with the following style in the CSS
.gwt-ScrollTable {
border-color: #aaa;
border-style: solid;
border-width: 1px 0px 1px 1px;
}
etc
That's the default style for the ScrollTable.
The solid border style apparently means that internally in the cell
the solid border is inherited into my widget - a HorizontalPanel that
I add the images to. Hence, the images are separated by a bit of white
space and a solid, vertical line.

GETting a request to another server from hosted mode while debugging (whitelist?)
Hi,
I am debugging a piece of code that GETting a request to a server that
isn't localhost. The code looks like this:
public void recieveRequest(final ServerResponseRecipient
callbackOnCompletion) {
this.callback = callbackOnCompletion;
final RequestBuilder rb = new RequestBuilder(
RequestBuilder.GET,
URL.encode(
http://my.server:9080/myShopInstall/DownloadReport.do?
content=dq_candidate_matchesformat=excel_csv
));
rb.setHeader(Content-Type, application/x-www-form-
urlencoded);
rb.setRequestData();
rb.setCallback(this);
try {
rb.send();
} catch (final RequestException e) {
throw new RuntimeException(e);
}
}
Is the ANY way that I can make hosted mode on my development machine
allow this request despite the single-origin policy? If not, I have to
live with at much slowed down build/test cycle...
Sincerely,
Anders

Re: Can I remove (+) and (-) knees from GWT Tree?
...and the answer is:
Make a TreeImages descendant that uses transparent images for the
knees.
interface NoKneesTreeImages extends TreeImages {
@Resource(dk/ange/gwt/dataqualitybrowser/public/images/
transparent-16x16.gif)
public AbstractImagePrototype treeClosed();
@Resource(dk/ange/gwt/dataqualitybrowser/public/images/
transparent-16x16.gif)
public AbstractImagePrototype treeOpen();
}
Use it when constructing the Tree.
private final TreeImages images = (TreeImages)GWT.create
(NoKneesTreeImages.class);
private final Tree actionsTree = new Tree(images);
You will need a small, transparent gif or png image.
Please remember to modify the paths to the images to reflect you own
package structure.

Can I remove (+) and (-) knees from GWT Tree?
Hi, Subject really says it all. I would like to use GWT Tree on a panel as a pop-up menu with grouped menu items, but the expand/collapse knee is a bit of an eyesore for that purpose...

ScrollTable and DockPanel: ScrollTable expands CENTER panel to hide SOUTH
Hi all, I am trying to do something relatively simple: I want to create a simple, three-pane email-like item browser interface. For that I'm using a DockPanel to host the components, namely queries, result list and single item viewer. The queries go in the WEST panel, the result list goes in the CENTRE panel, and the single item viewer goes in the SOUTH panel. When I use a simple Grid wrapped in a ScrollPanel for test, this works as expected. The result list fills up about half of the height of the screen and grows a scrollbar. However, when I replace the Grid/ ScrollPanel combination with a ScrollTable from the Incubator projects, the ScrollTable fills up the entire height of the screen, rather than confining itself to about half the screen like the Grid/ ScrollPanel did. Any ideas? Sincerely, Anders S. Johansen, ange.dk --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
