11 min readDragging an image object in a wxPython GUI involves handling mouse events to update the position of the image as the user drags it with the mouse. You start by binding mouse event handlers to the events like EVT_LEFT_DOWN, EVT_MOTION, and EVT_LEFT_UP. When the user clicks on the image, capture the initial position of the mouse and the image. As the mouse moves, update the image's position based on the current mouse position minus the initial position to maintain the relative drag effect.
