Setting VIEWPORT_X_POS hide the stack canvas
AverMar 15 2011 — edited Mar 15 2011In Forms 6i i use the next command:
set_view_property(l_canvas_stack_name, VIEWPORT_X_POS, l_canvas_stack_x_pos);
when the l_canvas_stack_x_pos > 0 (in my case = 175).
But instead of move it to different x position the command hide the canvas (its disappear from window).
What can be a problem?
