cell-horizontal-padding

Arguments: grid-row grid-column

Returns a non-negative integer indicating the breadth (in pixels) of margins along the left and right 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-horizontal-padding method returns 4. 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-vertical-padding.
