Re: how to show horizontal scrollbar in scrollpanel automatically?
No, the scrollpanel overflow property is already auto, but the horizontal
scrollbar cannot be shown in ie8 or FF13
I set the css using
scrollPanel.getElement().setAttribute(style,
width:210px;height:247px;border:1px solid #B5BBC8; overflow:auto;);
In FireFox, I use firebug and see
element.style{
border: 1px solid #B5BBC8;
height: 247px;
overflow: auto;
width: 210px;
}

This is not a standard behavior. You must have a CSS style applied to your
scroll panel or its content which resets overflow property. It should be
overflow:auto.

Re: ListDataProvider and VM use up memory
Sorry, what is server-side caches and second level cache? On Fri, Nov 9, 2012 at 12:50 AM, Ümit Seren uemit.se...@gmail.com wrote: Exactly for that reason there are server-side caches. Just set up a second level cache (ehcache, etc) and that should solve your scaling issue. If you use Spring as a backend technology it's a couple of configuration lines to add second level cache for Apart from caching there is the question if it really makes sense to transmit 10.000 records to the client. Mostly your users will just search in this huge list. The advantage of transmitting everything at once is that you can search exclusively on the client and you won't need any request to the server. However serializiation and de-serialization of 10.000 records will take some time and it will also increase memory consumption on your browser. You can also go a hybrid approach. Transfer around 2.000 rows using a AsyncDataProvider and once your search criteria is that specific that you have all the records at the client side you can do client side filtering (but programming-wise that's a little bit more involved) On Wednesday, November 7, 2012 10:00:59 AM UTC+1, tong123123 wrote: for using LIstDataProvider, if the search result contains many records and many users use similar criteria to search simultaneously, it will use up the memory of the server JVM easily, is this correct? So for searching record with large result, we should use celltable with pager and data provided by AsyncDataProvider so can break down the search result in server into smaller size, is this correct? For example, if the search criteria return 10,000 record at once time using ListDataProvider and if 500 ppls search using same criteria simultaneously, the server JVM memory will use up. So if using AsyncDataProvider, each time the search result is smaller (from onRangeChange) and so the chance of used up the memory in the server JVM is decrease, is this correct? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: how to export a ArrayListString in gwt to external file?
I do not underatand how to implement step 2 and 3, so I try to use GWT-RPC
to call servlet to export the data, to simplify the case, I just try to
hardcode the output text first, with the following code in the
RemoteServiceServlet
public void exportHistory(ArrayListString sqlHistory){
this.sqlHistory = sqlHistory;
try {
HttpServletResponse res = this.getThreadLocalResponse();
res.setContentType(text/plain);
res.setHeader(Content-disposition, attachment;

ServletOutputStream out = res.getOutputStream();
out.println(test1);
out.println(test2);
out.flush();

I have not tested this, but the following should do the trick for you.
1) Write a method to convert your sqlHistory to a string with the desired
line returns (if you want each list entry on a separate row).
2) Convert it to a DataUrl for a text file with MIME text/plain
3) Open a new window with the URL from (2) to trigger a file download.

Re: How to make CellTable Header always on top
I really get confused. in my result page, the hierarchy of widget is DialogBox encloses TabLayoutPanel encloses FlexTable, the FlexTable has three rows. in the first row, after I add a SimpleLayoutPanel with setSize(100%, 360px); and then encloses the DataGrid inside SimpeLayoutPanel, the DataGrid can shown now. But the problem is...SimpleLayoutPanel is also implements RequiresResizehttp://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/RequiresResize.html, so why can I just use 100% but not an exact px unit? The TabLayoutPanel has an explicit size in unit of px, then the FlexTable has setWidth(100%), is this the cause so I can use just % in the enclosing SimpeLayoutPanel? Also, I see DialogBox has not implements RequiresResizehttp://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/RequiresResize.htmland ProvideResizes, so if the outer browser windows shrink, the DialogBox will not resize accordingly, this is expected, right?

Re: How to make a hourglass pointer?

showHourGlass.addClickHandler(new ClickHandler(){
@Override

//showDefaultCursor();
RootPanel.get().setStyleName(defaultCursor);

};
// delay running for 1 seconds
t.schedule(1000);
}
});
}
}
and the css is as follow:
.waitCursor{
cursor:wait;
}
.defaultCursor{
cursor:default;
}
and found some problem,
1) after click the button and move the mouse cursor away from the button
and then stay (not move), the cursor will change to wait but will not
change back to default, I need to move the cursor to make it return to
default state.
2) even I keep moving the mouse cursor, I found the time to return to
default cursor is longer than 1 sec even I set
t.schedule(1000);
3) If the mouse cursor not leave the button, the cursor is still in hand
shape and the user can continue click the button many times.

Re: how to go to a widget at the top of the page
For more information, I am using GWT 2.4. the errMsgPanel.getElement().scrollIntoView() is called inside a button clickHandler.

Re: about css style in gwt
Sorry, I still have something not clear.
if the css selector is
.gwt-MenuBar .gwt-MenuItem
then under normal html, how to use it?
class=gwt-MenuItem
class=gwt-MenuBar .gwt-MenuItem
seems both does not work.
I try to create a label, and if I write the css as
.gwt-Label .innerTitle
then I found no method to use it, but if I just write
.innerTitle
then in gwt, I can simply use
addStyleName(innerTitle);

ton123123,
The intent is to prevent CSS namespace pollution. It is common
practice to use a makeshift namespace for your CSS selectors so as not
to break existing CSS selectors. Say for example you had a rule for
.closeButton . If anyone else used that selector in their module,
you might be overriding and breaking their CSS. So, you use a
makeshift namespace. Let's say everything in your module is inside a
container, then you could make that selector
.myModuleContainer .closeButton and now it will only apply to your
module and not break any others.
This is why .gwt-MenuBar .gwt-MenuItem is used. There could be .gwt-
MenuItem items that appear in places other than the menubar, so use
this more specific selector to only apply to the menu items of
interest.
A better step is to use the CSSResource feature of GWT, and then
you'll never need to worry about these collisions as each selector can
have a unique name, and your CSS will parse faster.

Hope that helps.
Sincerely,
Joseph

/* properties applying to the menu bar's menu items */
}
.gwt-MenuBar .gwt-MenuItem-selected {

I cannout underatand, why the css rule is
.gwt-MenuBar .gwt-MenuItem
but not
.gwt-MenuItem
?
I am not good in css, is
.gwt-MenuBar .gwt-MenuItem
is equal to just one css class? not any special meaning for the prefix
.gwt-MenuBar, that is
we can rename it as
.gwt-MenuBargwt-MenuItem will not any different?

Re: ImageResources cannot show image as expected
I try to run a gwt compile but still have no any clue. anyway, for the worst case, I can still use Image ha_logo_files = new Image(imagepath); without using ImageResources On Thu, Mar 8, 2012 at 12:12 PM, JoseM jose.a.marti...@gmail.com wrote: Maybe the ehealthlogo.png is missing from the proper folder or it is misspelled. Look at the logs in the GWT Jetty window it might say something (make sure to set the Level to Debug). Or you can also run a gwt compile that usually gives warning and errors when there is something wrong. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
