Grid

Description

If enabled, this event is reported when the user double-clicks a mouse button whilst over a cell in a Grid. The purpose of this event is to allow an application to enable some special action on double-click. This event may not be disabled.

The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 9 element vector as follows :

[1]	Object	ref or character vector
[2]	Event	'CellDblClick' or 163
[3]	Y	y-position of mouse (number)
[4]	X	x-position of mouse (number)
[5]	Button	button pressed (number) 1 = left button 2 = right button 4 = middle button
[6]	Shift State	sum of shift key codes (number) 1 = Shift key is down 2 = Ctrl key is down 4 = Alt key is down
[7]	Cell row	integer
[8]	Cell column	integer
[9]	Title index	integer

The y and x position of the mouse are reported relative to the top-left corner of the Grid.

The cell row and column are ⎕IO dependent

If the user clicks over a row title, the value reported for the column is ¯1, and the value reported for Title index is the index of that row title in RowTitles, or, if RowTitles is not defined, the row number. Column titles are handled in a similar fashion.
