add-class-grid-row

Arguments: class-grid data-object &key index scroll-into-view focus-on-row

Adds a single object to the list of objects that a class-grid is displaying. An alternative is to replace the whole set of displayed objects by calling (setf value) on the grid, passing a list of all objects to display.

Internally this creates a class-grid-body-row and adds it to the body row-section of the grid-widget.

class-grid is the class-grid to which an object will be added.

data-object is the new object to display. It should be an instance of the edited-class of the class-grid.

index specifies the position of the new grid-row among the existing rows. It may be either an integer index, where zero means to add the row at the very top, or else nil to add the row at the very bottom. The default is nil.

If scroll-into-view is true, then the body row-section will be scrolled as needed to make the new row fully visible. If nil, then this is not done. The default is nil.

If focus-on-row is true, then the keyboard focus within the grid will be moved to a cell of the new row. If nil, then this is not done. The default is nil. A true value still does not move the keyboard focus to the class-grid itself, but when it is next moved there the focus will be in the new row. An application could call set-focus-component to move the focus to the class-grid to allow the user to immediately edit the new row.

Modifying the list of instances that a class-grid displays will call the grid's on-change function because the list of instances is stored as the value property of the widget.
