Flex Examples

In a previous example, “Setting the column width of a tile in a TileList control in Flex”, we saw how you could change the width of a tile in a Flex TileList control by setting the columnWidth property.

The following example shows how you can set the row height of a tile in a Flex TileList control by setting the rowHeight property in MXML and ActionScript.

Full code after the jump.

View source is enabled in the following example.

You can also set the rowHeight property using ActionScript, as seen in the following example:
