Pagination control with Tableviewer [message #79211]

Hi folks,

I am looking to create a componenet using tableviewer which will have
pagination controls and also buttons to export the data displayed in the
table as a csv/excel/html file.

I am using the SWT.Virtual style for creating the viewer and hence the
data is loaded on need per basis. However, how do I provide pagination
control?

I tried tableviewer.getTable().setTopIndex(0) and on clicking NEXT I set
it to tableviewer.getTable().setTopIndex(10). But the data does not
refresh in the table.

What am I missing? Any Ideas ...

Thanks,

Arpit

Somehow I endup getting run time error as follows:

Could not evaluate javascript response:

'undefined' is null or not an object

org.eclipse.swt.EventUtil.suspendEventHandling();var req =
org.eclipse.swt.Request.getInstance();req.setRequestCounter(

What I am doing is as follows:

btNext.addSelectionListener(new SelectionAdapter(){
@Override
public void widgetSelected(SelectionEvent e) {
System.out.println("TopIndex:" + enclosureViewer.getTable().getTopIndex());
enclosureViewer.getTable().setTopIndex(index + incr);
System.out.println("TopIndex after next:" +
enclosureViewer.getTable().getTopIndex());
enclosureViewer.refresh();
}
});

Is this a bug ?

Hi Arpit,

I tried to reproduce what you described, but all worked as expected.
Could you provide some standalone code that reproduces the problem?

Cheers,
Rüdiger

Thanks Rudiger for getting back on this. I implemented it in a new
project and it works fine for me now :)

I am still very new to RAP and so take time to figure things out.
