Thanks for the reply. It resizes all right, and it also gets to viewmatcc when 
I try to viewmat a second time.

Probably not. I needed it for j602, which uses older wd gui and may not be 
compatible on the interface level with qt.

Does it update the display after you resize the form? I had to add glpaint to 
refresh the display. This is wd/isigraph method, the qt implementation may 
require different update.

The code looks for existing locale with jviewmat. If not found, it just 
launches original viewmat, thus creating a new window. If not, then it tries 
updates isigraph control in the existing window using viewmatcc verb which is 
specifically designed with this functionality in mind. Now I do not have j80x, 
but I would not be surprised if the structure of jviewmat is mostly retained 
there.
