Hi David,

Lots of big and good changes there.
I need to utilize a slider within a component. I believe the
AjaxExample
does not pass the current value of the slider back to the component,
which is what I need my component to do.
Is there an example which shows the AjaxSlider sending its value
back to the
component available for study? Otherwise, any hints as to how I can
send
the value back to the component for further processing?
The AjaxGridNavBar does this. Here is an example set of bindings:
BatchSlider: AjaxSlider {
orientation = "horizontal";
value = currentBatchIndex;
minimum = 1;
maximum = displayGroup.batchCount;
onChangeServer = updateGridContainer;
onSlide = "function(v) { $('currentBatch').innerHTML =
Math.round(v) }";
onChange = "function(v) { $('currentBatch').innerHTML =
Math.round(v) }";
id = "BatchSlider";
}
The relevant code from AjaxGridNavBar:
/**
*Intended to be bound to Ajaxslider for selection of batch to display.
*
*@paramnewValue
* new batch number from AjaxSlider
*/
public void setCurrentBatchIndex(Number newValue) {
// Right now the value returned is a BigDecimal. KVC changes this to
an
// int by narrowing, so that 4.9876402 becomes 4.
// If we round this instead, the slider movement is more inutuitive,
// especially with smaller batch sizes.
if (newValue instanceof BigDecimal) {
int roundedIndex = new Float(((BigDecimal) newValue).floatValue() +
0.5).intValue();
displayGroup().setCurrentBatchIndex(roundedIndex);
}
else {
displayGroup().setCurrentBatchIndex(newValue.intValue());
}
}
/**
*@return value for AjaxSlider
*/
public int currentBatchIndex() {
return displayGroup().currentBatchIndex();
}
Does that help?
