HI Brian and all.
Brian, Thanks for the detailed explaination.
I assume Mac uses x and y pixcel coordinates positioning for objects on the
screen. I am going to explain a possible way to make any GUI IDe to work and
give you the necessary feedback to identify where objects are located on the
form or what ever you want to call it. To explain the concept I am referring
too:
Main app window starts at the app top left hand corner starts at 0/0. the
Bottom right hand corner ends at 600/800. I have used the standard 600 by
800 pixcel screen. If I have mix the maximum size around for give me. But
you get the idea. The OS knows the application window size now.
Any object contained within the App window only knows the dementions of the
app window. So if an object top left hand corner is placed at 10/10. the
bottom right hand corner is placed at 100/100. So your object is 10 pixcels
away from the app border. Likewise applies to the bottom right hand corner.
Also you can quickly work out the size of the object. Any objects that are
placed on top or over the object can also be worked out with not to much
trouble.
As you move around the form, VO could inform you of the relative pixcel
x/y position. If the object you are placing on to the form covers another
object. It would not be that difficult to identify if it is at the top left,
bottom left, top right or bottom right corner. Over the top of the object
completely. On the top, bottom, left or right borders.
I have performed exactly what I have described under the windows environment
using Jaws for Windows and VB6. Yes, I am steeling ideas from windows. but
this works. There are floors of course. But you can get a basic window
design completed. Then someone with sight can polish the layout if required.
I have heard of totally blind people laying out forms without requiring
anyone to modify it.
