Arguments: grid-row grid-column
Returns a non-negative integer indicating the breadth (in pixels) of
margins along the top and bottom sides of a grid cell (specified by
the grid-row and grid-column
arguments) in a grid-widget
to reserve between the
cell's border and whatever is drawn in the cell. The built-in draw-cell methods call
this function to determine where to draw text in the cell; these
built-in draw-cell methods include the ones
for the special widget mixin columns such as editable-text-column-mixin
, as well
as the default draw-cell method that simply draws
a string from the object that is returned by read-cell-value and data-read-converter.
The default cell-vertical-padding method returns 2. An application may supply methods to change the padding for built-in cell types, and also for custom cell types if the associated custom draw-cell methods call this generic function and use the returned values (which is not required).
See also cell-horizontal-padding.
