CellDblClick Event 163
Applies To: 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.
