Hi,
I have a problem on how to draw and redraw a free object.
I use free object option provided by fdesign to create some lines.
These lines will change length according to the values that other routine
defined and the values will change with time. I draw the lines at the handle
routine using fl_line() and call fl_redraw_object() whenever a new set of data
are available. However, the objects (lines) I've defined have no change, they
remain their original shape whatever I change their value (x,y,x,y,col). I'm
sure the pointer pointing to that free object is correct, but still has no
effect. Can anyone tell me how to draw and redraw that kind of free object.
Have a nice day!
Regards,
Ricky
