List.rowCount
Availability
Flash Player 6 (6.0.79.0).
Edition
Flash MX 2004.
Usage
listInstance.rowCount
Description
Property; the number of rows that are at least partially visible in the list. This is useful if you’ve
scaled a list by pixel and need to count its rows. Conversely, setting the number of rows
guarantees that an exact number of rows is displayed, without a partial row at the bottom.
The code
my_list.rowCount = num is equivalent to the code
my_list.setSize(my_list.width, h) (where h is the height required to display num
items).
The default value is based on the height of the list as set during authoring, or as set by the
List.setSize() method (see UIObject.setSize()).
Example
The following example discovers the number of visible items in a list:
var rowCount = my_list.rowCount;
The following example makes the list display four items:
my_list.rowCount = 4;
The following example removes a partial row at the bottom of a list, if there is one:
my_list.rowCount = my_list.rowCount;
The following example sets a list to the smallest number of rows it can fully display:
my_list.rowCount = 1;
trace("my_list has " + my_list.rowCount + " rows");
