GWT Suggest Box

[rahul neekhra]

Hi,
 
I have a requirement where i dont have to show the Suggestion in a dropdown 
as we show it in Google search page,  but I need to display all the 
suggestions in a separate page. I get to know this is there in 2.4 version 
but what we call it, any URL which can help me in implementing it?
 
Thanks
 
Regards
Rahul

Re: Is there a way to create "cross-platform scripting" in GWT?

[Oliver Krylow]

Why does your code need to run on the JVM?

If I was in your position, I would look for a Gwt-only solution. It
definitely supports your use case,  look at JSNI and the ScriptInjector.

https://www.google.com/url?q=https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsJSNI&sa=U&ei=COLRUZbQA4mFtAbvioHQBg&ved=0CAgQFjAA&usg=AFQjCNGfT9UPdKfETb1mMCigT1bLnSruHg

https://www.google.com/url?q=http://www.gwtproject.org/javadoc/latest/com/google/gwt/core/client/ScriptInjector.html&sa=U&ei=2-LRUabPC8XRtAbZwID4Cg&ved=0CAcQFjAA&usg=AFQjCNFUtlqJqyMonzcQM6PMrxIoWl2SsQ

Nonetheless, overall I would advise to use such techniques as little as
possible. They make large and complex code bases unstable and hardly
testable. They are meant to provide an interface to existing javascript. If
your code base is not going to be large and complex, why are you using gwit
;-)

Re: RPC AsyncCallback freezes chrome

[markmccall]

We are seeing a very similar behavior in our application as well.  CPU hits 
13% and stays steady.  Opening the Chrome Dev Tools when this happens does 
not work.  Refreshing the page to reload the application does not work.  If 
I move to another browser tab and then come back the page will go blank.  
It is inconsistent and difficult to reproduce.  In fact I have not been 
able to reproduce when Chrome Dev Tools are open. Cannot reproduce in IE or 
Firefox.  Like I said, it's difficult to reproduce so I have not been able 
to create a simple version of the app to reproduce.   I have just started 
looking at this so I don't have any extra information to provide other than 
"+1".

Entering GWT Design mode gives "unable to instantiate class ToolkitProvider"

[Tim Clarke]

Noob alert - I'm just installing and working through the GWT tutorials but 
I've got stuck with this error at the point when I've opened the generated 
.java test file and I click on its "Design" tab:

Internal Error

encountered unexpected internal error.

This could be caused by a bug or by a misconfiguration issue, conflict, 
partial update, etc.

org.eclipse.core.runtime.CoreException: Plug-in "org.eclipse.wb.swing" was 
unable to instantiate class "org.eclipse.wb.internal.swing.ToolkitProvider".


Help please :/

Re: Adding close button to TabPanel(to its TabBar exactly)

[sandeep adari]

just try with tapPanel object say tabPanel.setClosable(true);
This statement should provide the close button as you are expecting.

How to avoid freezing with CellTable?

[sebastien . ribeil]

Hi everybody,
I'm creating a website with GWT. I want to add CellTable into my project. 
The problem is that I have a lot of data to put into the tables. So, my 
website freeze and show my table after 2-3 minutes. 

I find on internet that multi-threads are impossible with GWT. So, what is 
the solution? Even if the user have to wait 2-3 minutes, I want to avoid 
the fact that it's freezing.

Any Ideas?

Thank you.

My code, maybe I can optimize it simply?

public void refreshTable(final ArrayList arrListFilters, final 
ArrayList arrListAll, String url) {

// Get the CQ result
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);

try {
Request response = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
}

public void onResponseReceived(Request request, Response response) {
final json json = JsonUtils.unsafeEval(response.getText());

int i = 0;
int j = 0;
int tot;

// If there are too many results
if (json.getResultslength() > 1) {
tot = 1;
} else {
tot = json.getResultslength();
}

// Fill the list of rows
while (j < tot) {
i = 1;
List rowTemp = new ArrayList();
rowTemp.add(json.getDate(j));
// Get the data to get a price result for a specific
// customer query
arrListLnNb.add(json.getLineNb(j));
arrListId.add(json.getId(j));
arrListCqid.add(json.getCqid(j));
while (i < arrListFilters.size()) {
rowTemp.add(json.getResults(j, arrListAll.indexOf(arrListFilters.get(i;

i = i + 1;
}
rowTemp.add("");
rows.add(rowTemp);
j = j + 1;

}

// Provide rows to the table
table.setRowCount(rows.size(), true);
table.setRowData(0, rows);

final ListDataProvider> provider = new 
ListDataProvider>(rows);

provider.addDataDisplay(table);

// Handler to sort the columns
List> list1 = provider.getList();

ListHandler> columnSortHandler = new 
ListHandler>(list1);
i = 0;
while (i < table.getColumnCount()) {
final int columnIndex = i;
columnSortHandler.setComparator(table.getColumn(i), new 
Comparator>() {
public int compare(List o1, List o2) {

if (o1 == o2) {
return 0;
}

// Compare the name columns.
if (o1 != null) {
return (o2 != null) ? o1.get(columnIndex).compareTo(o2.get(columnIndex)) : 
1;
}
return -1;

}
});

i = i + 1;
}

table.addColumnSortHandler(columnSortHandler);

i = 0;
while (i < table.getColumnCount()) {
table.getColumnSortList().push(table.getColumn(i));
i = i + 1;
}
}

});
} catch (RequestException e) {
}
}

Re: How to disable text clear when i hit "Esc" in SuggestBox

[Jens]

You could also use a key handler:

@UiHandler("suggestBox")
void onKeyUp(KeyUpEvent event) {
  if(event.getNativeKeyCode() == KeyCodes.KEY_ESCAPE) {
event.preventDefault(); //IE clears text on ESC. We don't want that.
  }
}

If you want that behavior throughout your app (which would be a good idea 
because of UI consistency) you should extend SuggestBox, override 
onBrowserEvent (or use an internal key up handler) and then use your 
customized SuggestBox everywhere.

Hi David,
as you told i have used preventDefault and it working fine, can you plase 
let me know the below code is fine/ or is there any better way
 
 
*final* SuggestBox suggestBox = *new* SuggestBox(suggest) {

*public* *void* onBrowserEvent(Event event) {

*super*.onBrowserEvent(event);

*boolean* *esc* = *false*;

*switch* (event.getTypeInt()) {

*case* Event.*ONKEYDOWN*:

*if* (event.getKeyCode() == KeyCodes.*KEY_ESCAPE*) {

DOM.*eventPreventDefault*(event);

}

*break*;

}

}

};

Re: How to disable text clear when i hit "Esc" in SuggestBox

[David]

That is default behavior of a text input field (set back to what it was
before starting to edit).
I guess you could do a preventDefault on the ESC key event.

Re: How to disable text clear when i hit "Esc" in SuggestBox

[Dayananda B V]

Hi Jens,
 
thanks for replay, what i want is when i type a text suggestbox and when I 
hit escape key, whatever the text I entered is clearing. 
i don't want to clear the text.

Re: How to disable text clear when i hit "Esc" in SuggestBox

[Jens]

I am using GWT 2.5.1 and when I hit ESC in a SuggestBox nothing happens at 
all. Thats what I would expect as SuggestBox does not handle ESC explicitly 
(see SuggestBox.addEventsToTextBox()). You can also try it yourself 
using: 
http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwSuggestBox

I would guess its an issue in your app and not in GWT.
