Auto TextBox & TextArea Growth Demo and Source (inside)

2011-10-22 Thread Brandon Donnelson 
I've been working on a Growing TextBox and TextArea automatically expanding 
dynamically as you type into the input. I've got a little bit more tuning to 
do on the TextArea but its workable version. 

See the growth in action:
http://demogwttextexpand.appspot.com - Demo - Source link at the top.

Fore me the challenge is TextArea ComputedStyle cloning and calculation.

Re: DataGrid auto-set column width

2011-10-22 Thread jaga 
Okay - for the first solution I did as follows:
1) for each row of data
1.1) for each field
1.1.1) count the number of characters
1.1.2) keep a running maximum
2) finally you have an array of maximum sizes where each index
corresponds to a column, e.g. List maxes;
3) for each cell column
3.1) set the width to the maximum using the unit EM.
Note: this is likely to make the column a little bigger than required.
You can also try the Unit EX

Re: Multiple Entry Points & GWT Designer, how to choose..

2011-10-22 Thread John Gentilin 
Konstantin,

When you say this is in trunk, is it in the release version.. I've
search around
but haven't found any reference to gwtd.module.use. To get by I have
been
renaming the entry points I am not using to .txt, would be nice to
take advantage
of the gwtd.module.use feature if it exists today.. If it is in the
release product,
can you point me to docs on how to utilize it..

Thank you
John Gentilin

JSRange.insertNode

2011-10-22 Thread gangurg gangurg 
Folks ,

I am trying to solve this native Java Script issue on IE  but unable to .
Any thoughts on this .
what  am trying to achieve here is add a widget  into a text area .
 In Firefox this seems to work fine .
//Element = new VerticalPanel().getElement();
private native void addNode(JSRange range, Element element)
/*-{
range.insertNode(element);

}-*/;


in IE this does not work fine , i have to fall back on something like
range.pasteHTML(string) . This is good in certain cases , but lets say if i
use certain GWT widgets like Anchor, CheckBox  , the widget appears fine but
since this is a string i loose the events which are  attached to the widgets
like ClickHandler etc.  Any thoughts .

Re: future of gwt & who use gwt

2011-10-22 Thread krespo 
when I good understand, google wanted for some period support GWT, but they 
don't want to extend funciontality of GWT(maybe will recover existing bugs). 
They want to migrate existing GWT users into DART. 
But in this Dart way I see some disadvantages against GWT eg: 1. java lang 
on client and server , 2. same model class for client server side ... .I 
think that there  will be compatibility between java <-> dart and stay RPC 
mechanism.
What Do you think about my opinion ?

Long story short:
"What is the future of the JSCompiler and GWT?
JSCompiler and GWT were already on a merger path.  This effort gives us a
direction for that unification around the Dash language.  We will actively
support teams for a long time on the current generation of JSCompiler and
GWT and provide fantastic co-existence and migration tools to Dash."

Don't worry, it will be supported for long time beside the fact,
according to the linked email, it will be part of bigger something by
the time.

Re: How to test multiple interfaces of a widget in MVP ?

2011-10-22 Thread David 
I prefer MVP part 2 as well.  It lets me leverage @UiHandler in my uib
views thus further reducing boilerplate code in the presenter.I
found that GIN is essential to its success esp if you are considering
Junit testing without a web container.   Others essentials are Mockito
and Jukito

Here's an example of how I've followed mvp part 2:

SampleUIB .java...
public class SampleUIB  extends Composite implements SampleView

SampleView.java..
public interface SampleView{
   public interface Presenter {
void buttonPressed(String fieldValue);
   }
   void loadData);
}

SamplePresenter.java..
public class SamplePresenter  implements SampleView.Presenter {..
  @Inject private  SampleRpcAsync sampleService;
  @Inject private  private  Table3View view;

-david





The solution is to move to the "part 2" article and follow the advice
here:
> do not use HasXxxHandlers/HasValue/etc. interfaces but make up your own
> Presenter interface, single point of interaction from the view to the
> presenter (the view then pushes to the presenter, rather than the presenter
> pulling from the view).

[UIBinder] Row Click Handler on flexTable.

2011-10-22 Thread IDeshpande 
Hi All,

I am using UIBinder for my application in which I have added a
FlexTable to show my details. I want to add a clickHandler or a row
select functionality where on clicking the row of flexTable I give a
popup.

So, i wanted to know how to add a rowClick for the FlexTable? Could
anyone please give me a example for it??


Thanks in advance.

future of gwt & who use gwt

2011-10-22 Thread krespo 
Hallo, I have 2questions:
1. How is the future of gwt , after Dart release ? Will you continuously 
migrate users into Dart, or Dart hasnt impact on GWT platform ?
(GWT use RPC, but Dart not, it's not java)
2. where can I found some GWT real world applications (please URL) ?

Re: how to use an existing composite image in GWT

2011-10-22 Thread Thomas Broyer 
You can't.

You can use it as a DataResource and then either use it in a CssResource 
just like a "basic" CSS sprite (i.e. not a @sprite), grabbing the image URL 
(possibly an embedded data: URL) with @url; or with an Image widget using 
setUrlAndVisibleRect, or your can implement the ImageResource interface 
returning the appropriate values for the methods (i.e. implement 
ClientBundle yourself rather than relying on the generator). That last 
approach makes your code "forward compatible" with ClientBundle, so you can 
later switch to a "real" ClientBundle without changing your code (you can 
even use a  rule so you can GWT.create() your implementing 
class in your code, just like if it were using the generator); the only 
difference is that you cannot use your "fake" ImageResource within a 
CssResource (with @sprite).

If I were you though, I'd split the individual images and use "real" 
ClientBundle+ImageResource (and  @sprite in a CssResource if you need).

how to use an existing composite image in GWT

2011-10-22 Thread Yogesh 
Hi,

I already have a composite image with me. How can I use this composite
image along with ClientBundle / ImageBundle in GWT to show different
images extracted from this composite image?

Regards,
Yogesh
