GWT Incubator ScrollTable row navigation/selection using keyboard
Hi All, I am trying to use GWT Incubator's (Paging)ScrollTable for a keyboard centric application. It is important to be able to navigate between rows in a Table via the Keyboard (up/down) buttons. I understand that the table can have a RowSelectionPolicy, but can the selection be done with a keyboard? An example of what I am looking for can be found at http://demo.vaadin.com/sampler#TableKeyboardNavigation Your help is much appreciated.

gwt-visualization Table vs gwt-incubator ScrollTable
Hi, I have seen examples of both and like both of them, at least for the basic purpose of displaying data in Table form and with paging. However, I am unable to pick one over the other for the following reasons: a) Both lack "Column Reordering using Drag and Drop" that I wish in my Table View. I realize that one can use gwtQuery or gwt-DND to achieve the same, but I am not sure with which one it would be easier. b) I would want to replace default column headers with some clickable buttons - to achieve : i) hide a given column ii) show small popup picking a filter on the column. Not sure with which one of the two, its feasible (or easier) to achieve. c) I am not sure whether gwt-incubator stuff will ever ( or when) will it get into main gwt-library d) It seems that gwt-visualization is JSNI wrapper over original google visualization JS library. Is it going to be a big factor in terms of performance? e) Any guidelines on why & when should one pick one over the other!

incubator SCrollTable scroll position.
Hello Folks,
I am using incubator gen2 ScrollTable. I have a use case, wherein i have to
detect that when the user has scrolled to the last row (or somewhere around
the last row), then load a fresh set of rows in the table, via a rpc call.
TO achieve this i have extented ScrollTable and implemented
HasScrollHandlers.
public class UbqScrollTable extends ScrollTable implements HasScrollHandlers
{
public UbqScrollTable(FixedWidthGrid dataTable,
FixedWidthFlexTable headerTable) {
super(dataTable, headerTable);
}
public HandlerRegistration addScrollHandler(ScrollHandler handler) {
return addDomHandler(handler, ScrollEvent.getType());
}
}
And later in some other view i am setting up this table, and the initial
data to go along with it.
When trying to get the scroll position, i do this. st is the scrolltable.
st.addScrollHandler(new ScrollHandler() {
public void onScroll(ScrollEvent event) {
int top=event.getRelativeElement().getScrollTop();
int
scrollHeight=event.getRelativeElement().getScrollHeight();
int left=event.getRelativeElement().getScrollLeft();
int width=event.getRelativeElement().getScrollWidth();
GWT.log("Scroll data: top: "+top+", scrollHeight:
"+scrollHeight+", y: "+event.getNativeEvent().getScreenY()+", x:
"+event.getNativeEvent().getScreenX()+", left: "+left+", wiodth: "+width+",
class: "+event.getSource().getClass().getName());
GWT.log("Top:
"+st.getDataTable().getElement().getScrollTop());
GWT.log("Height:
"+st.getDataTable().getElement().getScrollHeight());
//st.getElement().setScrollTop(50);
}
});
All the values top, height, left, width are all constant and not changing. I
know there is something wrong with my understanding. Please help.
How do i get the scroll position, or "Detect that the user is viewing the
last few rows of the scroll table" so load new rows from backend?
Please help.
Thanks,
Subhro.

Re: incubator ScrollTable
All right...
Is there a way to make the FixedWidthGrid (where is the content of the
table) take widths automatic to each column, just like the Grid and
FlexTable does?

I don't know if is the better solution, this maybe:
public void afterLoad () {
if ( tablaScroll.getDataTable().getColumnCount() == 1) {
// setColumnWitdh
} else {
// otra cosa.
}
}

incubator ScrollTable
Hi, I'm just starting using the gwt-incubator. I need to make a table, so I am using a FixedWidthFlexTable to the header and a FixedWidthGrid to the dataTable (content of the table). I have a procedure that mounts the dataTable The problem that I am having is: when my dataTable have more than one column, the dataTable is ok I am setting the width to 100%, so my table fits my div at all. But when my table have only one column, I don't know why the column width stays to short Of course, if I use the method setColumnWidth of the FixedWidthGrid works fine, but I use the same procedure to generate all tables of my application, so I can't do that!!! I don't know if I gave a good explanation about my problem. I am trying to use the Firebug to discover what i am doing wrong, but the HTML code generated is a little confused. Is ther anything in the FixedWidthGrid about the first column of the table, or is there a way to I set all widths of my table like automatic? I appreciate any help Thanks... -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT Incubator - ScrollTable with TextBox
I think you want getWidget(), not getText(). Cast the result to TextBox (or perhaps HasText if you want something more generic) and get the text from that.

GWT Incubator - ScrollTable with TextBox
Hi all, I wanted to know if Scrolltable is a panel good enough to hold TextBox widgets. I have created a ScrollTable (using gwt-incubator_1-5_Dec_28) with TextBoxes in a particular column and labels in other columns. I can extract the label value using the function "scrollTable.getDataTable().getText(row,col)". But i am not able to get the value at the TextBox using this function. It always returns null. Am i missing something here? Is there any other way to get the value of the text in the textBox present at a particular cell? PS : I am not using the TextBox array logic to get the data at the textBox because there are certain problems when i delete the row in the scrollTable.

Re: Incubator ScrollTable how to remove icon right-top corner
My solution is this:
1. Create a new CSS class:
.not-displayed {
display: none !important;
}
2. In my PagingScrollTable subclass's ctor:
for ( int index = 0, numWidgets = getWidgetCount(); index <
numWidgets; index++ ) {
Widget widget = getWidget( index );
if ( widget instanceof Image ) {
// Well, we can't remove the widget...AbstractScrollTable
prevents that. So, add a style that
// will cause it to not be displayed...
widget.addStyleName( "not-displayed" );
break;
}
}
I know it's fragile, but having the button just confuses my users.
Please...make sure that when this widget graduates to core that:
1. This button's behavior is configurable
2. The button's presence is configurable
thanks,
jay

Re: Incubator ScrollTable how to remove icon right-top corner
Hi Mike, A possible solution would be to subclass the PagingOptionsImages image bundle interface and place your own images named the same as the PagingOptionsImages methods in your subclass package. This should replace the standard paging table images with your own (which I think in your case would be blank images). Alternatively, you could override the methods in the PagingOptionsImages in your subclass and @gwt.resource annotations pointing to images with names of your choice.

Incubator ScrollTable how to remove icon right-top corner
Hi, I'm not sure if this is the right place for incubator questions. I haven't been able to find the incubator group. I am using the scroll table from the incubator, it has a small icon (2 mini arrows pointing left and right). I would like to remove/hide this icon. Any ideas?

Re: incubator ScrollTable
Nic,
I had the same problem with the IndexOutOfBoundsException.
I fixed the demo code to get it working with the gen2 package:
public void onModuleLoad() {
int numStudents = 100;
...
FixedWidthGrid dataTable = createDataTable(numStudents, 10);
./.
/**
* Create the data table.
*
* @return a data table
*/
private FixedWidthGrid createDataTable(int rows, int cols) {
// Create a new table
FixedWidthGrid dataTable = new FixedWidthGrid(rows, cols);
// Set some options in the data table
dataTable.setSelectionPolicy
(SelectionGrid.SelectionPolicy.MULTI_ROW);
// Return the data table
return dataTable;
}
Best Regards,
Johan Vermeire

Incubator: ScrollTable, hide and sort column
Hello, I'm using Scrolltable from the incubator without problem, untill I tried to hide a column (not the last one but one at the beginning). When I tried to sort the visible columns, I found that by clicking on a header cell, it was sorting the previous column and not the good one. Is it a bug from the scrolltable ?

Re: incubator ScrollTable
Nick, The widgetideas classes are deprecated because they are being replaced by newer, improved versions in the gen2 package. The old classes are still around to help people who are transitioning to the gen2 versions. I'm not aware of a completely comprehensive guide to incubator widgets, but there is a lot of demo code that can be very helpful. The JavaDocs are also a good place to look for information on widget API. - Isaac On Fri, Feb 27, 2009 at 9:57 AM, Nick wrote: > > Well, I was able to get this working by swapping out the gen2 imports > with the widgetsideas package.

Re: incubator ScrollTable
Well, I was able to get this working by swapping out the gen2 imports with the widgetsideas package. I'm noticing that all the classes are deprecated though. Is there a reason for this and is there someplace that explains more details on using the incubator widgets?

Re: Incubator: ScrollTable
Hi Francesco,
I'm using the ScrollTable myself and I was able to make the columns to
be of fixed width simply by setting the minimum, preferred and maximum
widths of my column(s) to be of the same value. e.g if you're being
consistent with the example code provided:
private TableDefinition createTableDefinition()
{
// definition for a column
{
StudentColumnDefinition colDef =
StudentColumnDefinition("Col 1") {
}
}

Incubator: ScrollTable
Hello, I have been using the ScrollTable widget (com.google.gwt.gen2.table.client.ScrollTable) in the incubator and I find it very useful. I need to add a "Row Header" section which contains fixed columns that do not move when scrolling horizontally. I have studied the AbstractScrollTable (com.google.gwt.gen2.table.client.AbstractScrollTable) class code which implements most of the ScrollTable functionality and I think the "cleanest" and best way to add a Row Header would be to add a FixedWidthFlexTable that implements it, much in the same way the existing headerTable has been implemented. Has anyone done this before? Are there any best practices to change the current code in the incubator (AbstractScrollTable class code would need some substantial parts added to it)? An abovious solution would be create my own class that extends AbstractScrollTable, but this contains either private or protected instance variables (for example Element absoluteElement, the widget main DIV container), so I'd rather go for the cleanest approach possible...
