SmartGWT - Update ListGridRecord dynamically
- by Haylwood
I am using SmartGWT and I have a ListGrid populated with an array of ListGridRecords using the setData() call. I am trying to update a progress property of a single record (on a timer for testing) and have it update in the browser. I have tried various combinations of draw(), redraw(), markForRedraw() etc. to no avail.
I also tried overriding the updateRecordComponent() method in my table class, but it only gets called when the records are first created (after createRecordComponent()).
I should note that I do NOT want to accomplish this by binding to a DataSource. I just want to be able to update the attribute on the client-side.
ArrayList<SegmentSortRecord> mRecords;
mRecords.add(new SegmentSortRecord("03312010_M001_S004"));
mRecords.add(new SegmentSortRecord("03312010_M001_S005"));
mRecords.add(new SegmentSortRecord("03312010_M001_S006"));
mRecords.add(new SegmentSortRecord("03312010_M001_S007"));
SegmentSortRecord[] records = new SegmentSortRecord[mRecords.size()];
mRecords.toArray(records);
mSortProgressTable.setData(records);
.
.
.
mTestTimer = new Timer()
{
public void run()
{
mTestPercent += 5;
if (mTestPercent <= 100)
{
mSortProgressTable.getRecord(2).setAttribute(Constants.PROGRESS_COL_NAME, mTestPercent);
//mSortProgressTable.markForRedraw();
//mSortProgressTable.redraw();
}
else
{
mTestPercent = 0;
}
}
};
...
@Override
protected Canvas createRecordComponent(final ListGridRecord aRecord, Integer aColumn)
{
String fieldName = getFieldName(aColumn);
// Want to override the behavior for rendering the "progress" field
if (fieldName.equals(Constants.PROGRESS_COL_NAME))
{
Progressbar bar = new Progressbar();
bar.setBreadth(10);
bar.setLength(100);
// The JavaScript record object contains attributes that we can
// access via 'getAttribute' functions.
bar.setPercentDone(aRecord.getAttributeAsInt(Constants.PROGRESS_COL_NAME));
return bar;
}
Thanks in advance for any help.
