The context associated with the cell type. See the Remarks for more information.
Gets the editor's value.
Syntax
var instance = new GcSpread.Sheets.CustomCellType();
var value; // Type: object
value = instance.getEditorValue(editorContext, context);
function getEditorValue( 
   editorContext : object,
   context : object
) : object;

Parameters

editorContext
The DOM element that was created by the createEditorElement method.
context
The context associated with the cell type. See the Remarks for more information.

Return Value

Returns the editor's value.
Example
This example creates custom cells.
