Select the Free Transform tool and resize the component to fit your application. Select Frame 1 of the Timeline and, in the Actions panel, enter the following: my_list. dataProvider = myDP; If you have defined a data provider named myDP, the list fills with data.

Select Control > Test Movie to use the list to stop and play the my_mc movie clip instance. Using the List component 765 To create a List component instance using ActionScript: 1. Drag the List component from the Components panel to the library. This adds the component to the library, but doesn't make it visible in the application. Select the first frame in the main Timeline, open the Actions panel, and enter the following code: this. createClassObject(mx. controls. List, "my_list", 1); my_list. addItem({label:"One", data:dt1}); my_list. addItem({label:"Two", data:dt2}); 2. This script uses the method UIObject. createClassObject() to create the List instance. 3. Select Control > Test Movie. Customizing the List component You can transform a List component horizontally and vertically while authoring and at runtime. While authoring, select the component on the Stage and use the Free Transform tool or any of the Modify > Transform commands. When a list is resized, the rows of the list shrink horizontally, clipping any text within them. For more information about scroll bars, see "ScrollPane component" on page 1093. Using styles with the List component You can set style properties to change the appearance of a List component. 766 List component A List component uses the following styles: Style themeColor Theme Description Halo The base color scheme of a component. Possible values are "haloGreen", "haloBlue", and "haloOrange". The value can be an array of two or more colors, for example, 0xFF00FF, 0xCC6699, and 0x996699. Unlike single-value color styles, alternatingRowColors does not accept color names; the values must be numeric color codes. By default, this style is not set and backgroundColor is used in its place for all rows. The default color is white and is defined on the class style declaration. The background color when the component's enabled property is set to "false". The List component uses a RectBorder instance as its border and responds to the styles defined on that class. A Boolean value that indicates whether the font specified in fontFamily is an embedded font. This style must be set to true if fontFamily refers to an embedded font. If this style is set to true and fontFamily does not refer to an embedded font, no text is displayed.
