ICellRenderer  - AS3 Flash

Gets or sets an Object that represents the data that is associated with a component. When this value is set, the component data is stored and the containing component is invalidated. The invalidated component is then automatically redrawn.

The data property represents an object containing the item in the DataProvider that the cell represents. Typically, the data property contains standard properties, depending on the component type. In CellRenderer in a List or ComboBox component the data contains a label, icon, and data properties; a TileList: a label and a source property; a DataGrid cell contains values for each column. The data property can also contain user-specified data relevant to the specific cell. Users can extend a CellRenderer for a component to utilize different properties of the data in the rendering of the cell.

Additionally, the labelField, labelFunction, iconField, iconFunction, sourceField, and sourceFunction elements can be used to specify which properties are used to draw the label, icon, and source respectively.

Gets or sets the list properties that are applied to the cell--for example, the index and selected values. These list properties are automatically updated after the cell is invalidated.

Gets or sets a Boolean value that indicates whether the current cell is selected. A value of true indicates that the current cell is selected; a value of false indicates that it is not.

Sets the x coordinate of the cell renderer

Sets the y coordinate of the cell renderer

Sets the current cell to a specific mouse state. This method is necessary for the DataGrid to set the mouse state on an entire row when the user interacts with a single cell.

Parameters

Sets the size of the data according to the pixel values specified by the width and height parameters.

Parameters

To run the example, follow these steps:

1. Add the List and Button components to the library.
2. Save this code as ICellRendererExample.as in the same directory as your FLA file.
3. Set the Document class in the FLA file to ICellRendererExample.
