    How to detect when control is scrolled into view

    PiedSoftware posted a topic in VCL

    Hi I have a TScrollBox that I am placing a number of "Cards" that are TFrame subclasses onto. As the number of cards increases, the performance of loading the list of cards initially is getting too long. Is there a way to delay loading these cards until they are scrolled into view? i.e. is there a way to trap the event of a card being shown in the scroll box?
