focus-cell

Arguments: grid-widget

Returns multiple values to indicate where the keyboard focus currently is within the grid-widget passed as the single argument. The values returned are

1. row-section
2. column-section
3. row
4. column
5. row-index
6. column-index

If the row-section that contains the grid's focus has no subsections, then the returned row and row-index will each be nil. Similarly, if the column-section that contains the grid's focus has no subsections, then the returned column and column-index will each be nil.

Otherwise, the row-section, column-section, row, and column will always be instances of the grid-row-section, grid-column-section, grid-row, and grid-column classes (respectively) or their subclasses, and the row-index and column-index will each always be a non-negative integer indicating which replication of the row or column has the grid's focus (this is always 0 for a non-replicated row or column).

The above values are returned even when the grid-widget itself does not have the keyboard focus, indicating to where the keyboard focus will return if and when it returns to the grid-widget. If the grid-widget has not yet had the keyboard focus, then the first replications of the first subsections of the first row-section and column-section will be returned.

To move the focus to a different grid-widget cell programmatically, call set-focus-cell.
