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 ?
