Re: Last Page too big in SimplePager
Hi,
to avoid this issue, you have to override the
setPageStart(int index) method in the AbstractPager class.
with the following code:
/**
* Set the page start index.
*
* @param index the index
* @see #getPageStart()
*/
protected void setPageStart(int index) {
if (display != null) {
display.setVisibleRange(index,
display.getVisibleRange().getLength());
}
}
This code will set the startindex of the page as expected. But be
careful the size of the CellTable will be reduce, because you have
less rows!

I noticed that if you call setRangeLimited(false), you get the behavior
that
you expect, but the forward buttons do not get grayed out.
If you look at setPageStart(int) is uses isRangeLimited and display's
isRowCountExact() values to determine whether or not pageSize records
should
be shown. If both are true you will get yourpageof pageSize. It seems to
me that if isRangeLimited, meaning whether or not thepagerange should be
limited to the actual data, is true you would want to only see the 5
remaining records instead of a fullpageof pageSize records.
So what I did was copy AbstractPager into my project and change
isRangeLimited to !isRangeLimited in setPageStart(int). See code below:
protected void setPageStart(int index) {
if (display != null) {
Range range = display.getVisibleRange();
int pageSize = range.getLength();
if (!isRangeLimited display.isRowCountExact()) {
index = Math.min(index, display.getRowCount() - pageSize);
}
index = Math.max(0, index);
if (index != range.getStart()) {
display.setVisibleRange(index, pageSize);
}
}
}
You could also extend SimplePager and accomplish the same thing...
Can someone from the GWT team comment on this?
Thanks,
Pat

Last Page too big in SimplePager
I use the SimplePager to page my CellTable. I have setup an
AsyncDataProvider for the data but know beforehand how many rows there
will be
All the pages display fine, but the last. It is as big as the other.
If I have a PageSize of 10 with 15 elements, the last page shows
elements 6 through 15. I'd prefer to have only 11 through 15 shown.
The solution I came up with, is to add the following lines of code to
onRangeChanged in my AsyncDataProvider:
int start = range.getStart();
int maxRows = form.getFormDataCount().get(formDataState);
if(start + range.getLength() == maxRows) {
start = maxRows - (range.getLength() - (start %
range.getLength()));
display.setVisibleRange(start, maxRows - start);
}
And I call my data provider with the new start and size parameters
this does the trick but I'm sure there is a better solution
