GWT 2.4.0 - SelectItem does not work when I use application via Android
Hi I have developed a web application in GWT 2.4.0 (SmartGWT 3.0p), but I found a problem when I try to access it via mobile (Android Samsung S2 tablet). Substantially every SelectItem does not work properly. When I open one of them to select a row, I tap on the record but it only remais highlighted and the SelectItem does not close (and the row is not selected). I have observed that if the SelectItem contains many records and the relative scroll bar becomes visible, everything works correctly. Some of you have found similar problems?

Re: Best way to share common css defs in a GWT application with multi-module
So if I define a color in common.css like this: @def black #000; I can reuse the black definition in Foo e Bar CssResources? On Monday, July 28, 2014 2:43:35 PM UTC+2, Davide Micheletti wrote: The easiest way to do this is to create a common module that the two modules inherit. You would put the CSS in the parent, and include it from both the child modules. Here is an example. Suppose you have two modules: com.company.apps.foo.Foo and com.company.apps.bar.Bar. These would have the following Java source tree: src/ com/ company/ apps/ foo/ Foo.gwt.xml client/Foo.java public/Foo.html bar/ Bar.gwt.xml client/Bar.java public/Bar.html You want to put company.css somewhere where it is available to both. To do this, you might create a new directory: like src/com/company/apps/public/ and then put your company.css file in there. You would then need to create a GWT module for Foo and Bar to inherit from. Your new tree would look like this: src/ com/ company/ apps/ public/company.css Common.gwt.xml foo/ Foo.gwt.xml client/Foo.java public/Foo.html bar/ Bar.gwt.xml client/Bar.java public/Bar.html Common.gwt.xml would look something like this: module inherits name=com.google.gwt.user.User/ public path=public/ /module Then you would add a line like this to Foo.gwt.xml and Bar.gwt.xml: inherits name=com.company.apps.Common/ This will cause Foo and Bar to inherit all the settings from Common. The particular setting you are interested in will be the 'public' directory from Common, which contains your shared CSS file. Give that a try, and see if it works for you!

GWT ScrollPanel not scrolling when hidden
I have a ScrollPanel and I want to reset his scrolling position when it is
hidden.
To do so I call the scrollTop method. As I can see it is not working only
when the ScrollPanel is hidden.
Here a sample code:
public void onModuleLoad() {
StringBuilder html = new StringBuilder();
for (int i = 0; i1000; i++) html.append(row +i+br);
HTMLPanel content = new HTMLPanel(html.toString());
final ScrollPanel scrollPanel = new ScrollPanel(content);
scrollPanel.setHeight(200px);
RootPanel.get().add(scrollPanel);
RootPanel.get().add(new Button(TEST, new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
scrollPanel.scrollToTop();
scrollPanel.setVisible(false);
scrollPanel.scrollToBottom();
scrollPanel.setVisible(true);
}
}));
}
After clicking the TEST button the ScrollPanel keep is top position.
Any idea how to scroll it when hidden?

Basically gwt-jet is a fast, flexible and easy way to wrap business objects (any pojo actually) that you want to show at the front-end. The jet classes automatically create the corresponding widget and autopopulate thru reflection the user modified values into the original object. Please, check gwt-jet site http://code.google.com/p/gwt-jet/ for simple and more complex examples. Maybe someone else will find it as useful as we did. Thanks for your time.

Hi,
I ran into a problem about clicking the reload button on a web
browser.
My app is a stateful GWT app. Users need to be authenticated for
login. After login they can surf on various pages. But users sometimes
were used to press the reload button on the browser to refresh the
page.
The reloading process just bring the screen back to a reboot state,
with all state info lost. That's not what we expect.
The quick solution is, catch the reload event before the browser
sends the reload request to the web server and prevent the browser
from sending it.
I have read the relevant posts in this group and found the useful
info that reload event is equivalent to the Window Closing event. So
in the following code snippet I can catch the event,
Window.addCloseHandler(new CloseHandlerWindow() {
public void onClose(CloseEventWindow event) {
//prevent browser sending the reload request to the
web browser
}
});
But I don't know how I can stop the browser from sending the
reload request to the web server.
Thanks for any help,

The solution now in place includes: Use Grid instead of FlexTable Build the Grid before adding to the scroll panel or other panel This was only an issue in IE Thanks, Ernie On Mar 5, 3:33 am, Lex alexey.tsiunc...@gmail.com wrote: Hello all, And we are generating the Table HTML on server side, and put it as innerHTML and have performance 1000 rows - 3-4 second in IE. The biggest problem is using components which should handle events and placed in such table, but it seems JSNI is a solution in this case. In our case Links already working. So it seems this is the optimal solution if you need high performance. On Mar 4, 7:36 pm, eadams harriersoftw...@comcast.net wrote: Thanks for the suggestions. Changing the code to add the FlexTable to the scroll panel after loading the data resulted in a good improvement. The 268 row parts list will now load in IE in just over 5 seconds. I tried the setVisible () suggestion as well, but that did not yield much change. The changes yielded an elapsed time of 0.3 seconds in Firefox.

This elapsed time is after thedatahas been received from the server (which is also very fast). All of the above is on a Windows Vista client using IE 7. Testing the same code on FireFox 3.0.6, the 268 rows display in under 1 second. Is this a known problem with IE and are there any work arounds? Unfortunately FireFox is not a solution for this issue as the company's only approved browser is IE. It's a rendering issue and not the only one. Try creating a Tree with 100.000 elements and have a look how much fun you have with InternetExplorer and Firefox (Safari is very fast here which makes me jealous). One thing I haven't tried but you might try out is adding the flex-table to the panel after adding all rows. This might speed up things because InternetExplorer seems to redraw the whole table when adding rows (this is not GWT- specific, I had the same effects with other web-frameworks in the Good Old Days(R) as well). Or - if that has no effect - you might play around with setVisible.

Re: FF vs IE, when dealing with Lists
+1 for the custom hp solution
for the best performance at all i suggest a flow panel with inside
a list of flowPanels anc custom css styles

Hi Nick,
Flex table is pretty slow if you want to display 50+ rows in it at a
time based on our experience. The slowness also varies for each
browser, only realistic way of getting around this problem is to
implement pagination, where you display only 20-30 rows on each page
and then provide links on the header to navigate through the pages.
This way i am able to manage a display of thousands of records in less
than 500 milliseconds across the browsers (FF and chrome faster then
IE).
The application has many views with this approach displaying simple
tabluar data and also hierarchical data structures.
For displaying hierarchical data structures i initially went with
Tree, but that was pretty slow for large no. of rows, so i simulated
tree inside FlexTable using Click listener on (+/-) images.
This works like a charm.
Regards,
Milind

Ok, Results
What I’m finding is that the Grid does beat the FlexTable, but not by
much with a small data set. Larger sets seem to widen the gap. My
guess for this is that since FlexTable has the ability to add rows
(Grid is sized from the start) that it works much like how other
resizable constructs work such as Java’s ArrayList. My reasoning for
this is that the first time the test is run the speed is very slow on
the FlexTable (especially in IE). Repeated test runs after the
initial are faster and I think this is because the table was being
sized the first time as rows were added, and didn’t need to be resized
during the following tests.
The other thing I’m finding is that performace varies based on
browser. I’m seeing FF run reasonably well. With IE the Grid runs
about the same as FF but the FlexTable runs considerably slower. I
also tested Opera and was stunned as it blew both others out of the
water.
My full write up is here with times and a test application you can run
in your browser.

Thanks for the response, I think you're correct. And it makes sense
that adding rows dynamically would account for the increase in time as
the row count is higher.
I'm going to run a few tests, and I'll post anything I find to this
post.

Hello Nick,
Exactly the same issue was in our app. We need to display big lists
(100 - 500) records, and FlexTable seems not solution for this.
The problem is that FlexTable always checks table bounds (row number,
column number) and when you put some value in FlexTable it performs
checking for bounds, moreover it not store the colnum and rownum in
some variables, but always calculate them dynamically. Moreover it
dynamocally adds new rows.
Thats why it becomes slower when number of rows increase.
We had decided to use Grid rather then FlexTable. We can specify Grid
bounds right after creation, and while we put data in cells in the
cycle its performance remains the same for different grid size (here
I
mean speed of adding row).
But it also has it's disadvantages. When we need to display another
data in the same Grid, and this data has different number of rows,
we should call Grod.resize(int, int). And for
big grids, this operation is very slow in IE (in our tests resizing
grid with 200 rows, 5 columns, takes ~13000 ms in IE).
So It seems paging here the only solution.

Ok, I did some more testing and I was wrong. It's not the
inserting
and removing from lists that are the bottleneck. I moved the time
and
log statements around and it had to do with adding to the FlexTable
itself.
I'm using code like:
int row = 1;
for (IteratorMyData iter = eventList.iterator(); iter.hasNext();
row+
+) {
long sysTime = System.currentTimeMillis();
int column = 0;
MyData event = (MyData)iter.next();
table.setText(row, column, event.getNameLast());
column++;
table.setText(row, column, event.getNameFirst());
column++;
table.setText(row, column, event.getJob());
column++;
GWT.log(update time 4:
+(System.currentTimeMillis()-sysTime)+ms
, null);
}
Now, you can see I'm logging the time after every row is inserted.

override RemoteServiceServlet.processCall to process custom annotations
Hi i'd like to do the override of RemoteServiceServlet.processCall to insert the code for processing my custom annotations on service invocations. I've noted how the default processCall make use of the RPC class: ... return RPC.invokeAndEncodeResponse(this, rpcRequest.getMethod(), rpcRequest.getParameters(), rpcRequest.getSerializationPolicy ()); ... and expecially the method invokeAndEncodeResponse that i found difficult to reuse due to the fact that it has two distinct responsabilities when maybe it would be better to have splitted this method in two... anyway the problem i have it's this: in my processCall i'd like to have access to catch the exceptions throwed by my service method but invokeAndEncodeResponse don't rethrow an exception occurred during the service invocation, and of course it can't because normally it must encode the exception in the returned payload. On the other sida i'd like very much to reuse the RPC class because it do a lot of interesting things that i don't want to lose, any opinions on this... federico --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: align widgets left and right
you can use 2 nested Horizontal panel and one Horizontal panel as
container
es:
--
| - |
| | | || |
| -- |
--
setting HorizontalAlignment to left on the first nested Hp and to
right on the second.
then you can add the first 2 of your 3 widget to nested 1 and the
thirth to nested 2.

What would be the recommended way to align widgets left and right

My specific case is I would like to align three widget putting glue
space between the second and the third (like \hbox to \hsize{foo\quad
bar\hfil baz} in TeX).
I was using the following code as a hack and thought it was working
until I realized the buttonB is squished into very narrow button under
firefox-3.06 (was working on firefox-2 and Safari).
final TextBox textBox = new TextBox();
final Button buttonA = new Button(...);
final Button buttonB = new Button(...);
final HorizontalPanel headerPanel = new HorizontalPanel();
headerPanel.setWidth(100%);
headerPanel.setSpacing(5);
headerPanel.add(textBox);
headerPanel.add(buttonA);
headerPanel.setCellWidth(buttonA, 100%);
headerPanel.add(buttonB);
What would be a more robust and cleaner way to achieve this?
Thank you.
