Re: GWT + MySQL

[Vaibhav Shukla]

Hi Greg,
Finally I found someone who has been working on MySQL in GWT. I am working 
on a project that involves both. But I am kind of stuck with the similar 
issue. Can send a sample example to better understanding of GWT and MySQL. 
I am using GWT-RPC.

How to add/remove dynamic column to/from celltable.

[vaibhav bhalke]

Hi,

I am gwt celltable.

My columns are configurable through other module.
used AsyncDataProvider to update row data.


Is there any way in celltable to updateColumnData only? so that newly added
data get inserted into celltable or to remove column from celltable.

Assume, 10 column in table.
User can configure celltable column

- user want to remove 2 selected column then server call is made and
related recordList object along with columninfo (8 columns) is coming, but
in this case old 10 columns  with data and 8 column without data is
populated into celltable

Actual: 18 columns displaying in celltable, 10 column with data + 8 column
without data
Expected: 8 column with record

Sample code is as follows

 asyncDataProvider.updateRowData(startRowIndexOfPage, result);
   if ("CONFIGURE".equals(eventType)) {
cellTable.redraw();
createCellTableColumns(latestColumnList);
}
 cellTable.redraw();

result : record list with record information
latestColumnList : List : Updated number of column with column
information

I want to show only new data(column+record data) in celltable which comes
from server

If you want more info then replay me

How to do this?

GWT CellTable : How to override OnBrowseEvent for Custom EditTextCell?

[vaibhav bhalke]

   I am using GWT CellTable 2.1.

How to override OnBrowseEvent for Custom EditTextCell
(NumberCell,CustomStringCell etc..)?

In my CustomStringCell, I want to avoid space only at Initial position(1st
index) How to do?

I tried following way

@Override
public void onBrowserEvent(Context context, Element parent,
String value, NativeEvent event,
ValueUpdater valueUpdater) {
super.onBrowserEvent(context, parent, value, event, valueUpdater);
boolean isEditing = isEditing(context, parent, value);

if(isEditing){
if(event!=null){
info(" event.getKeyCode() = "+event.getKeyCode()+"
:: value ="+value);
if(event.getKeyCode()==32){
event.preventDefault();
return;
}
}
}
}

Current behavior using above code : User cant edit space at all *
--
*

*In Case of CustomStringCell:*

*Expected* : @User should not edit space at 1st index of textString. *
_myString* is not allowed in CustomStringCell.

@User should use space between string like *Record_ID* or *
Google_Search_Engine* (Consider _ as space)

*How can I achieve this in OnBrowseEvent of CustomStringCell?*

*

*

*In Case of CustomNumberCell :*

Suppose my data type is Decimal.

OnBrowseEvent of CustomNumberCell I allowed only keycode of numbers[0-9],
backspace and dot ('*.*')

I want to allow only one dot ('*.*') in decimal

*Not allowed :* *_234* , *.123* , *13.223.23* , *123...23.23*

*How can I achieve in OnBrowseEvent of CustomNumberCell?*

*How to get new value from cell after each keypress ?*

*Any help or guidance in this matter would be appreciated.*

GWT Celltable : How to avoid entering particular value in editTextCell- column- Celltable?

[vaibhav bhalke]

Hi,

I am using GWT2.3.

How to avoid entering particular value in editTextCell- column- Celltable?

Is there any event  in editTextCell?

Validation while entering values in cells of celltable
In case of
String :Dont enter spaces in cell
Integer : Dont use characters

+ avoiding spaces in cell i.e if cell is type of string then user can't use
spaces
although user presses "space bar"  button multiple times then that spaces
should not be enter in cell a
How to achieve this ?


final EditTextCell editTextCell = new EditTextCell();

final Column stringColumn = new Column(
editTextCell) {
@Override
public String getValue(RecordVO object) {

}

@Override
public void render(Context context, RecordVO
object,SafeHtmlBuilder sb) {
// Any code?

}

column.setFieldUpdater(new FieldUpdater() {
public void update(int index, RecordVO object, String value) {
   // This will return updated value
}

Any help or guidance in this matter would be appreciated.

V

GWT SimplePager LastButton issue

[vaibhav bhalke]

Hi,

I am facing problem with lastButton of SimplePager. I have 3 pages in
celltable, Page size=11 (1 empty record + 10 records(with value)), Total
record=26.

I used CustomerPager by extending SimplePager.

In 1st attempt 1+10 records display in celltable : Next & Last page button
is enabled (First & Prev button disabled) which is correct. But LastPage
button not working... :( Dont know whats the issue...

Unexpected behavior:

@1 Last page button is working only when I visit to last page(3 page in my
case).

@2 Assume I am on 1st page n I moved to 2nd page(Total 3 pages in
celltable). that time all buttons are enabled which is correct. In this
case Last button is working but behave like Next Button

My GWT application integrated into one of our product so cant debug it from
client side.

May be index value is improper in setPage(int index) method from
AbstractPager

Code flow is as follows for Last button

*//From SimplePager

lastPage.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
  lastPage();
}
  });


   @Override
  public void lastPage() {
super.lastPage();
  }

 // From AbstractPager
  /**
   * Go to the last page.
   */
  protected void lastPage() {
setPage(getPageCount() - 1);
  }
 protected void setPage(int index) {
if (display != null && (!isRangeLimited ||
!display.isRowCountExact() || hasPage(index))) {
  // We don't use the local version of setPageStart because it would
  // constrain the index, but the user probably wants to use absolute page
  // indexes.
  int pageSize = getPageSize();
  display.setVisibleRange(pageSize * index, pageSize);
}
  }*

or may be some conditions false from above code(from setPage())

actual record = 26 and 3 Empty record (1st Empty record/page)

May b problem with dataSize :|

How I can check number of pages based on the data size? ?

How can I solve this problem?

GWT SimplePager : How to provide GoTo Functionality in pager?

[vaibhav bhalke]

Hi,

I am usign GWT2.3.
We developed CustomPager by overriding SimplePager.

We override createText() method such a way that we are showing string like
"Page 1 of 4" using following code

> public String createText() {
> if(searchRecordCount%pageSizeForText == 0){
> totalPages = searchRecordCount/pageSizeForText;
> }else{
> totalPages = (searchRecordCount/pageSizeForText) + 1;
> }
> NumberFormat formatter = NumberFormat.getFormat("#,###");
> return "Page "+formatter.format(this.getPage()+1) + " of " +
> formatter.format(totalPages);
>   }
>

[image: pager.PNG]

Now I want to use TextBox for CurrentPage so that user can enter page
Number in textBox. (Functionality GoTo entered pageNumber)

createText() returns string so I cant user textBox ;) + Can't provide css

How can I do this ? Is there any way to solve this problem? Workaround if
any or Sample code

Gwt celltable : Unexpected behavior : when record deleted from page then other record repeated in page.

[vaibhav bhalke]

Hi,
I am using celltable -- gwt2.3.
I found strange behavior in celltable.
My celltable's pagesize is 10. Total 13 records.
When Page contains 3 records
A 1 11
B 2 22
C 3 33

When I deleted any one record e.g. A record then that record is deleted
from page but other record repeated / sets in page.
i.e.
B 2 22
C 3 33
C 3 33
Page is trying to set 3 recods some how.
Expected 2 records in page after deleting 1 record

Whats wrong ? How to resolve this issue?

Re: Last Page too big in SimplePager

[vaibhav gwt]

Hi
I am using GWT2.3 Celltable

I'm using SimplePager and I want to show 11 items(users) per page.
1 empty records + 10 actual records = 11 records per page so
PageSize=11

 All my data is 36 items. I want to show text in Simple pager such way
that
Pager should display following values in my pager when PageSize=11 (I
am setting 1 empty record in grid)
i.e 1-10 of 36 11-20 of 36 21-30 of 36 31-36 of 36

Currently I am getting lots of issue like last  page showing
unexpected records. (expected 7 = 1 empty + 6 actual records)
pager showing unexpected startIndex ,lastIndex and
dataSize(totalRecordCount)

I am stuck in this pager  issue.

Any help or guidance in this matter would be appreciated


Does anyone know what's going wrong?

Re: how do i add a tooltip to a column header in a celltable ?

Hi,
Following e.g works only for Name of column header i.e. when we move
mouse on name of column header then only tool tip appear.

CellTable ct;
ct.addColumn(col, SafeHtmlUtils.fromSafeConstant("---header text---"));

We want too tip on entire column header not on name of column header.

GWT celltable How to create selectioncell in edittextcell ?

[vaibhav bhalke]

Hi,

I want to create editable cell with datatype boolean.

I don't want to use selectioncell for boolean data type

My testBooleanColumn column's cell contains string with value
true,false..

when I will click on cell present in testBooleanColumn then that cell
should be editable and In that editable cell  I want to show selection cell
with value(true,false).
when user changes value from selectioncell either true or false that value
set to editable cell in testBooleanColumn

How to do this? any hint ? or sample code for this use case ?

Vaibhav

Re: GWT Celltable How to make Non-Editable cell in Editable column

[vaibhav gwt]

Thanks Ozgur.

public void render(com.google.gwt.cell.client.Cell.Context context,
String value, SafeHtmlBuilder sb) {

if(context.getColumn()==2 &&context.getIndex()==0 ){

sb.appendHtmlConstant(""); // This non-editable cell
// This will work in mozila firefox ?   
}else{
super.render(context, value, sb);
 }

}
It works fine as per my use case. :)

Now problem is when I am performing pagination then next N-1 page's
2nd_column of 1st cell is editable :|
How can I do it as non-editable on pagination ?

GWT : How to call SERVLET FROM GWT_SERVLET and How to return value from target servlet to source servlet?

I have 2 servlets.

One In GWT module i.e *BasicServiceImpl* extends RemoteServiceServlet
implements BasicMassUpdateService

and other servlet *TargetServlet* extends HttpServlet in TargetServlet in
diff module/package com.comp.server.servlets

I am using GWT-RPC in my gwt module. I want to write one method
getRecordList() in BasicServiceImpl which returns list of record on client
side.(right now I am sending dummy data in record list)

In other servlet i.e TargetServlet RecordList formed from database value.

Use case: When we call getRecordList() method using rpc then I want to call
SERVLET : TargetServlet to get recordlist, TargetServlet will return
recordlist to getRecordList of Gwt_servlet and finally getRecordList()
returns recordlist on client side

1: How to call other servlet(TargetServlet) from GWT_SERVLET i.e *
BasicServiceImpl*

2: How to send recordlist from TargetServlet to getRecordList() of
BasicServiceImpl(GWT SERVLET)

GWT-RPC Unable to access servlet in web application

[vaibhav bhalke]

Hi,

I integrated my gwt module in to existing web application and deployed on
jboss.

when I trying to hit gwt_servlet then I am getting error message on failure
method of asynccallback

i.e. *The requested resource
(/warFileName/GWTAPPS/myGwtModuleName/GWTServletName) is not available.*

*
*

My war contain is as follows

*GWTAPPS* :

*myGwtModuleName*(folder) : (folder contains -->)advanced,css,gwt,images
folder and some *.cache.png files myGwtModule.html, myGwtModule.css

*WEB-INF* -> *deploy* - *myGwtModuleName*

I copied compiled gwt_servlet file into
/warFileName/GWTAPPS/myGwtModuleName/ still getting same error i.e resource
not available.

Is it necessary to crate WEB-INF/classes(copied *.class file) folder into
myGwtModuleName ?. like warfilename\GWTAPPS\mygwtmodule\WEB-INF\classes

Also getting sometime exception in deployment
java.lang.NoClassDefFoundError: com/google/gwt/user/client/rpc/RemoteService

*gwt_servlet entry made in web.xml*

*This web.xml is not present in GWTmodule.*

*
*

< servlet> < servlet-name>GWTServletName< /servlet-name> <

< /servlet> < servlet-mapping >

< servlet-name>GWTServletName< /servlet-name>
< url-pattern>/GWTServletName< /url-pattern>
< /servlet-mapping>

 also used url pattern like myGwtModuleName/GWTServletName

*RemoteServiceRelativePath added in BasicUpdateService*

@RemoteServiceRelativePath("GWTServletName")

public interface BasicUpdateService extends RemoteService

*Created a remote service proxy to talk to the server-side GWTMassUpdate
service.*

private final BasicUpdateServiceAsync basicUpdateService = GWT
.create(BasicUpdateService.class);

*Server call*

basicMassUpdateService.makeServreCall("vaibhav", new AsyncCallback() {

@Override
public void onSuccess(String result) {
  Window.alert("Result = "+result);
}

@Override
public void onFailure(Throwable caught) {
 Window.alert("On Failure  :"+caught);
//  No resource available :-|

});

GWT CELLTABLE :How to avoid RPC call in AsycDataProvider when I click on prev button.

[vaibhav bhalke]

Hi,

GWT CELLTABLE :How to avoid RPC call in AsycDataProvider when I click on
prev button.

I am using AsyncDataProvider to fetch data from server to celltable page.

 Each time when i click next button i am getting next 100 records from the
server. And it is displaying the data fine. No issues with next button.

When i click prev button, i am assuming that cellTable had stored the
previously displayed data, and just want to display that existing data.

How to handle this case without making RPC ?

ListDataProvider storing previously displayed data(previously added data in
dataProviderList )

Same way How we can handle in AsyncDataProvider ?

GWT CELLTABLE : How to add empty row in celltable with different celltype

[vaibhav bhalke]

Hi,

How to add empty row in celltable with different celltype ?

4 columns present in my celltable i.e
DatePickerCell,EditTextCell,NumberCell,SelectionCell

I can able to set record values in cell with different celltype.

I want to add empty row with different cell type in celltable also want few
of them editable and rest are non-editable.

I want to do MassUpdate in Celltable.So I required 1st row as empty because
whenever I will change value in particular cell which editable then all
values in that column should be updated immediately

Suppose I edited value in edittextcell of 1st empty row then all values in
same column should be edited immediately.

Any help or guidance in this matter would be appreciated

GWT : Best practice to send huge amount of data from server to client

[vaibhav bhalke]

Hi folks,

Which are the Best practices to send huge amount of data from  server to
client in GWT?

Right now we are facing performance issue in GWT code.

Our server side is sending huge xml (Size in MB/GB) to client side, our
client side parses that xml and using parsed data, beans are formed for
populating data in Celltable grid.
We are filling 1k + / 10k+ records in CellTable grid.

Is there any effective way/ Best practices followed while dealing with such
a huge data?

Re: GWT CELLTABLE:How to get Updated DataProviderList after changes in any cell value ?

[vaibhav gwt]

Thanks for your reply.

I set fieldUpdaters for each of cell so any changed in cell reflected
to dataProviderList :)

**.getDataProvider().getList() returns updated List

Re: GWT CELLTABLE How to restore old value in cell if validation fails

[vaibhav gwt]

Hi Loan,

Thanks for your solution. It works but  Performance is too bad.
i.e clearing incorrect values for the whole row (say 5) takes too much
time(clearViewData+ redraw table)

Reverting N records will take too much time :(

Is there any fast way to update old row/object in celltable ?




 // when setting up table columns add the edit cells to this list
 List editCells = new ArrayList();
 

 // clear incorrect values for the whole row
 for (EditTextCell editCell : editCells)
 {
  editCell.clearViewData(KEY_PROVIDER.getKey(object));

 }
cellTable.redraw();

Re: GWT CELLTABLE How to restore old value in cell if validation fails

[vaibhav gwt]

Thanks Loan :)
I can restore old value in specific cell if validation fails.

Is it possible that all column values from particular row restore to
old value ?
|| ID || Dept || Code || RNO || RCode
|| .||ZCode ||
|| 1  ||  CS   || 001  ||  3  ||  030
|| .||Q1||
|| 2 ||  DS   || 001  ||  5  ||   040

Suppose In above editable grid I changed 1st record i.e

|| .||Q1||
changed to
|| 1  ||  BP   || 010  ||  3  ||  003
||.||Q1||

Is there any way to restore old object(row) values instead to clearing
cell view data for each column and redraw editable grid.

In Short revert record to old value which is selected by our checkbox
(All or selected chkbox only i.e selectionModel.isSelected(object) )

My Grid contain (2-N) column so I am asking this question ?

GWT CELLTABLE How to restore old value in EditableTextCell?

[vaibhav bhalke]

Hi,

I want to used editableNumbercell like intger,decimal etc.. But there
is no such gwt widget present so I am using editable text cell and
using validation for numbers when user update value in cell.

Problem is that if validation fail then editabletext cell value
restored to old value.

intgerColumn.setFieldUpdater(new FieldUpdater() {
public void update(int index, RecordInfo object, String value) {
// Called when the user changes the value.
if(value.matches("(-)?(\\d){1,8}")){
object.setColumnInRecordEdited(true);
object.setValue(value);
RecordData.get().refreshDisplays();
}else{
Window.alert("Specify valid integer value for parameter");
// How to reset old value here? currently updated
value immediately set to cell

}

}
});

Any help or guidance in this matter would be appreciated.

GWT Sprite adds height attribute in the style class

[Vaibhav]

Hi,

  I have implemented ClientBundle in my application and so far it
is working fine until I came across this issue. I have a css class
which has a background image so I defined it as a sprite in my css. I
am using this css class on Button and it looks okay. But I lost
vertical text alignment inside Button. I did little research and I
found height attribute is added by GWT compiler for the height of the
image and that has disturbed vertical alignment of the text inside
button. When I removed height in firebug it looks all right. Is there
any way to workaround this issue?

Please note this happens in Firefox only. IE7 is fine. Help is
appriciated.

I defined my css class as below

@sprite .MarkitButton {
gwt-image : "MarkitButtonBG_sm";
color: white;
font-family: Arial, sans-serif;
font-size: 11px;
font-weight: bold;
cursor: pointer !important;
cursor: hand !important;
margin: 1px;
padding: 0px 4px;
text-decoration: none;
border: 0px;
overflow: visible;
};

and after compilation it becomes like below.

.G1wmgmpeN {
-moz-background-clip:border;
-moz-background-inline-policy:continuous;
-moz-background-origin:padding;
background:transparent url(data:image/
png;base64,iVBORw0KGgoNSUhEUgERCAYcw8YSJklEQVR42mMIqlz6n8Epc85/
BsXYnv8MAqFkEi1AwrcaSHgW/wcAqEchmT6lbh0ASUVORK5CYII=) repeat-x
scroll 0 0;
border:0 none;
color:white;
cursor:pointer !important;
font-family:Arial,sans-serif;
font-size:11px;
font-weight:bold;
height:17px;
margin:1px;
overflow:hidden;
padding:0 4px;
text-decoration:none;
}

Thanks in Advance

Re: MouseOverHandler not called for text of Checkbox

[vaibhav saxena]

Hi,
Why do you not create a composite which will act as the wrapper for the
check box and add the mouse handler to the composite. This will solve your
problem and you can use that composite anywhere where you need check box in
your app.

How to sing events on the mark up element

[vaibhav]

Hi,
I want to access the text box written in HTML from GWT on the basis of
element ID. I am able to get this elemt in GWT and also show that. Even I am
able to change the text of the text box but I am not able to add the events
to the element. How to add the event. I have written some bit of code but
not able to sink the event.

I have extended the text box to add the element

-

Public class MarkupTextBox extends TextBox{

 Public MarkupTextBox(String markupTextboxID) {
  
  This(DOM.getElementById(markupTextboxID));
 }

 Protected MarkupTextBox(Element element) {
  
  Super(element);
 }
}
-


And then adding listener to it

-
--
Final MarkupTextBox box = new MarkupTextBox("poctext");
Box.setText("Hi how are you");
Box.addClickListener(new ClickListener(){
Public void onClick(Widget sender) {
}});
Box.addChangeListener(new ChangeListener(){
Public void onChange(Widget sender) {
Box.setText("Hi how are you");
}});
-

May be I making some mistake. Please suggest me without the suggestion of
using the 
Third party lib like GWTTiger.

Warm Regards,
Vaibhav Saxena

Re: hi

[vaibhav]

 
Hi,
I think there is one more option for that as provided by GWT itself

Window.Location.getParameter("ProjID");
Hope this should work in you case. Window is the class provided by the GWT.
Location is the internal class of the Window which provides the methods to
play with the current window location.

Try this and also do answer me the in case of the success as I have not
tried this as well but logically it should work

You will have to assign the values to a var variable and then retrive
it from the gwt function using the native jsni within a function.
for instance using query in the html page declare and assign the value
to a variable:
For html page: http://localhost:/./myApp.html?ProjID=12345
 
var projectID = query['ProjID'];
 
And retrieve it in the gwt code by a function:
 
native String getProjectID() /*-{
if($wnd.projectID) {
  return $wnd.projectID;
}
}-*/
 
 
Hope this helps
Vishesh.

[vaibhav]

 

Hi,

How can I add another project source file into my GWT project. Actually I

Re: rpc with external servlet

[vaibhav saxena]

Hi Jason Essington

You are right that rpc will connect to server from which the host page is
generating but in my project approach is little bit different. Let me
understand you whole context.

My project was in dojo toolkit some months before. My whole team was working
on that in which we have the server side codes and in web content the js
files of dojo toolkit. Now my whole team decided to shift to GWT for some
incompatability issues in dojo. We are working on the rest architecture to
be compatable for other applications who understand the atom.

In GWT we tried with json and atom data and began to use the GWT-EXT as our
widgets library. We did the whole setup for the gwt client and as the data
was coming on the basis of rest architecture we didnt include the server in
it. Rather the server was in some workspace and GWT client was in some
workspace.

We used to test our gwt code using the external server code by just placing
the compiled files over there. The host page generating from the same server
and the the compiled js files is also on the same server but our client
developement workspace is different.

Now we need the rpc for some user preference. We need to use the same server
code may be with some changes on the servlet for rpc. Still the host page
will be generate from the same server side and the compiled js will be
placed over there too. The servlet will be in web inf directory.

i am confused in the client server directory structure of gwt. May be it is
enought to understand my problem. please help me out.

Thanks

Regards
Vaibhav Saxena
