processKeyDown Method

Javascript (Usage)
Javascript (Specification)

var instance = new GcSpread.Sheets.CustomCellType();
var value; // Type: boolean
value = instance.processKeyDown(event, context);

function processKeyDown( 
   event : KeyboardEvent,
   context : object
) : boolean;

Parameters

event: The KeyboardEvent.
context: The context associated with the cell type. See the Remarks for more information.

Return Value

true if processes successfully; otherwise, false.

This example uses the processKeyDown event. Click on cell (1,1) and use the up or down arrow key to change the value.

Javascript

sheet.rowFilter(new GcSpread.Sheets.HideRowFilter(new GcSpread.Sheets.Range(0,0,4,4)));
sheet.repaint();

You can override the isReservedKey method to customize the reserved key. In display mode, once isReservedKey returns True, the sheet will not handle the reserved key event. The event is handled by the processKeyDown and processKeyUp methods.

The context parameter can include the following items:

Item	Type	Description
context.sheet	GcSpread.Sheets.Sheet instance	Indicates the current sheet.
context.row	number	The row index.
context.col	number	The column index.
context.sheetArea	GcSpread.Sheets.SheetArea	The current sheet area.
