my_btn.tabIndex:Number
Property; lets you customize the tab ordering of objects in a SWF file. You can set the tabIndex property on a button, movie clip, or text field instance; it is undefined by default.
If any currently displayed object in the SWF file contains a tabIndex property, automatic tab ordering is disabled, and the tab ordering is calculated from the tabIndex properties of objects in the SWF file. The custom tab ordering only includes objects that have tabIndex properties.
The tabIndex property may be a non-negative integer. The objects are ordered according to their tabIndex properties, in ascending order. An object with a tabIndex value of 1 precedes an object with a tabIndex value of 2. If two objects have the same tabIndex value, the one that precedes the other in the tab ordering is undefined.
The custom tab ordering defined by the tabIndex property is flat. This means that no attention is paid to the hierarchical relationships of objects in the SWF file. All objects in the SWF file with tabIndex properties are placed in the tab order, and the tab order is determined by the order of the tabIndex values. If two objects have the same tabIndex value, the one that goes first is undefined. You shouldn't use the same tabIndex value for multiple objects.
The following ActionScript is used to set the tabEnabled property for one of four buttons to false. However, all four buttons (one_btn, two_btn, three_btn, and four_btn) are placed in a custom tab order using tabIndex. Although tabIndex is set for three_btn, three_btn is not included in a custom or automatic tab order because tabEnabled is set to false for that instance. To set the tab ordering for the four buttons, add the following ActionScript to Frame 1 of the Timeline:
three_btn.tabEnabled = false; two_btn.tabIndex = 1; four_btn.tabIndex = 2; three_btn.tabIndex = 3; one_btn.tabIndex = 4;
Make sure that you disable keyboard shortcuts when you test the SWF file by selecting Control > Disable Keyboard Shortcuts in the test environment.
