oh its oracle 10g! how to disable the stacked canvas using a button! what code?
The set_canvas_property built-in does not offer a mean to hide the canvas, but I think you could achieve that by using the HIDE_VIEW Built-in.
PROCEDURE HIDE_VIEW(view_id ViewPort);
PROCEDURE HIDE_VIEW(view_name VARCHAR2);
Here is an exampe from the documentation:
<pre>/*** Built-in: HIDE_VIEW
** Example: Programmatically dismiss a stacked view from the
** operator’s sight.
You could also try using the SET_VIEW_PROPERTY Built-in, which allows the modification of the view’s VISIBLE property.
