Hello, i searched the archive more then once about this and can not solve my
2 problems..
1)I open a file (image) with a listbox and store it in the variable filename.
Now i would like to perform some operations on the image, pressing a pushbutton.
How do i pass filename to the pushbutton callback funtion??
2)I calculate a certain matrix (with the help of this group btw, thx for
that!)in a function. Now i would like to use this matrix in another funtion: How
can i pass it to the other function??
Thx in advance, Sven.
