选择gwt celltable行

Question

I have a cell Table in GWT with columns , there are 3 rows in each column, I want the first row to get selected by default when the application starts

some thing like this

                 mycelltable.setselectedrow(index);

is it possible ?

Thanks

her is the code

                      display.getShortListedCVsBasedOnJob().getResumeDescriptionColumn().setFieldUpdater(

            new FieldUpdater<CandidateSummary, String>() {
                public void update(int index, CandidateSummary object,
                        String value) {

                    fetchResume(cvSelected, shortListedFlag);
                }
            });

This fetchResume() method calls but only when i select cell of this column , I want to call this fetchResume() method as my application starts, ie i want to make the 1st cell of the column to be selected byDefault.

Answer 1

Selection is handled by a SelectionModel , based on objects (not indices); so you have to select the first object from your data in the SelectionModel used by the CellTable (have a look at the Using a key provider to track objects as they change sample code in the Celltable javadoc for an example (last sample before nested classes summary ).

Answer 2

This could work?

setSelected(Element elem, boolean selected) 

see GWT Documentation

CellTable Google Web Toolkit

Hmm I dont see what´s the Celltable is there. I would set the initial Value like this:

int INITAL_SET_ROW = 0;
TableRowElement initalSetElement = yourCellTable.getRowElement(INITAL_SET_ROW);
yourCellTable.setSelected(initialSetElement, true);

You can try to implement it in you´re main Method. Haven´t tested it tho, hope it helps.

Simply;

List<RowType> source = new LinkedList<RowType>(); 
//put some data to this list
//populate the table
table.setRowCount(source.size(), true);
table.setRowData(0, source);
//for example, you can select the first row
RowType firstRow = source.get(0);
selectionModel.setSelected(firstRow, true);
