This problem is getting solved if i use the Refresh function in the button
handler. But I have a function where i am generating Jpeg images dynamically
in a separate script. And i need to load these images on GUI as soon as they
start generating. They have common names like xyz1.jpeg and xyz2.jpeg. And i
need to start loading images one after another on the gui panel when they
are created. these images are created one after another with a particular
time delay(not constant). So i have to check when they are created, and i
should load them on gui. So how should i communicate to the gui that image
has been created and it should load the image ?
