    Default which listener to use on video panel?

    hi, can anyone answer a quick and hopefully easy question?
    i have panel = window(new frame) and its used to render a video image on, i need to pickup a touchscreen press change of event but not sure which event listener to use and on which component. Any ideas?
    Is it a panel, window or frame event? and which listener would detect a focus change or a mouse press

    I know mouse listener and focus listener and window listeners are available but not sure they would be able to detect the screen press on the video rendered image

    thanks in advance

    Default Re: which listener to use on video panel?

    To know which listener you need to use you need to know what kind of events this touchscreen device generates. Most touch screen controllers emulate a normal mouse where a finger press on the screen is represented as a left MB click. This means you will likely be listening with a MouseListener for the MouseEvent, MOUSE_CLICKED. Notice this is a MouseEvent. The listener can be attached to any of the Panel, Window or Frame.
