system.dataset.deleteRow

Description

Takes a dataset and returns a new dataset with a row removed. Datasets are immutable, so it is important to realize that this function does not actually remove the row from the argument dataset. You'll need to do something with the new dataset that this function creates to achieve something useful.

Syntax

system.dataset.deleteRow(dataset, rowIndex)

Parameters

Dataset dataset - The starting dataset. Please be aware that this dataset will not actually be modified (datasets are immutable), but rather will be the starting point for creating a new dataset.

int rowIndex - The index (starting at 0) of the row to delete. Will throw an IndexError if less than zero or greater than len(dataset)-1.

Returns

Dataset - A new dataset with the specified row removed.

Scope

All

Examples

This example would remove the selected row from a List component, by re-assigning the List's data property to the new dataset returned by the deleteRow function.

myList = event.source.parent.getComponent("List")
row = myList.selectedIndex
if row != -1: # make sure there is something selected
   myList.data = system.dataset.deleteRow(myList.data, row)
