DockLayoutPanel can not show center element using uibinder
hello all:
below is a super simple app, which demonstrate the use of uibinder, so
strange that after lanching the app, i can only see the top part of
docklayoutpanel, nothing shows in the below part!
is there anything wrong? please help me out, thanks very much.
public class KeyProviderExample implements EntryPoint
{
public void onModuleLoad()
{
RootPanel.get().add( new ExpensesShell() );
}
}
public class ExpensesShell extends Composite
{
interface ShellUiBinder extends UiBinderWidget, ExpensesShell
{
}
private static ShellUiBinder uiBinder =
GWT.create( ShellUiBinder.class );
public ExpensesShell()
{
initWidget( uiBinder.createAndBindUi( this ) );
}
}

Re: the button and its infoLabel problem...
thanks very much Danny.

I think that you need a deferred command to handle this. Limit your
clickhandler to set the infoLabel to Beginning and then launch a
deferred command who's execute method performs the search and then
updates the label.
In this way, the execution thread will finnish, causing the screen to
be updated with the beginning label and then only the defrred command
will be executed.

thank Andreas and Aditya for your explanation.
however the problem has nothing to do with RPC, the search operation
i mentioned above is simply a local operation such as sort a large
chunk of data which will take seconds to completed. meanwhile the
client is unresponsive until the click OnClick() is completed, you can
simply simulate this situation by doing a while loop.
is there other way i can see the beginning... ? or GWT has the
ability to make UI responsive when it doing a time-consuming operation
in client?
thanks.

HeyShelley,
a bit of further information is missing but may it be that you issue
an RPC between infoLabel.setText(Beginning); and
infoLabel.setText(Completed);?
If so you simply forgot the async nature of GWT RPC. Your code in
onClick(...) will not sort of stop or wait until the RPC finishes and
continue afterwards. That's why infoLabel.setText(Completed);
will be immediately executed after infoLabel.setText(Beginning);
and you're simply way to slow to see it.
What you could do instead is call infoLabel.setText(Completed);
in your onSuccess(...) in case I'm right with RPC or in the callback
of whatever request you do for your search operation.

hello all:
i came across a strange problem which seems quite simple:
i have a button and a label on a panel, the button has been
registered a listener:
Button searchButton = new Button( Search );
searchButton.addClickHandler( new ClickHandler()
{
@Override
public void onClick( ClickEvent event )
{
infoLabel.setText(Beginning);
//do a search operation here which will take more than
5 seconds...
infoLabel.setText(Completed...);
}
} );
that's all, but i never see the Beginning“ on the label, but only
see the completed..., seem the label will not refresh it's text
until onClick is finished? how can i achieved the function that
display beginning... first and Completed... when the operation
completed?
thanks in advance.

Re: GWT IE Bug affecting RichTextArea, TextBox, etc.
Problem: The problem is a result of a RichTextArea being embedded in a TabPanel. To Reproduce: In IE8, add a RichTextArea to a TabPanel. Navigate to the Tab containing a RichTextArea. Leave the Tab without Focusing on the RichTextArea. The entire app enters a state where TextBoxes, TextAreas, and RichTextAreas cannot get focus. Solution: Set Focus on the RichTextArea when the TabPanel is opened. If the RichTextArea is in the first tab, then a Timer that sets Focus after some short delay will generate the focus event. Focusing on the RichTextArea enables the application to remain in a working state. Thanks, Brett On Mon, May 17, 2010 at 10:14 PM, Brett S. brett.h.shel...@gmail.comwrote: Hello, I am at a loss that I can only reproduce with IE8 (both XP and Win7). I would greatly appreciate any assistance. I have a GWT 2.0 application that has several DialogBoxes containing text boxes, buttons, etc. Everything works fine in Firefox, Chrome, etc. In one DialogBox, I have a TabPanel with three Tabpanels. One of the tabs has a RichTextArea. The first time I edit text in the TextAreas, everything is fine. The second or third time, the text area locks up. The TextArea takes no focus and does not allow editing. Buttons still work. I can close my DialogBox and open a completely unrelated DialogBox with a simple TextBox. This TextBox suddenly does not work either. Once the application goes into the no focus, no edit state for Text Entry Widgets, there is no return. No Text Controls work. Buttons, Menus, popup windows work fine though. In Dev and Production mode, no errors or exceptions are being thrown. I read in some older postings (2008) that TabPanels have trouble containing TextAreas. So, I removed the TextAreas from the TabPanel. The problem was not fixed by not having TextAreas in Tab Panels. My hope is that someone out there has experienced this problem. Please let me know if any workarounds exist. Thank you!
