Two Childs over each others, conflict with "WM_TOUCH_CHILD" and pMsg->hWinSrc

    hi,

    I have two child widgets over each others, bottom is a graph widget and the top is a button on a touch screen, when I touch the graph I get at the parent call back, at the message ID "WM_TOUCH_CHILD" a pMsg->hWinSrc of the graph handler, which is OK and no problem in that, but when I press the button wich is over the graph , I get at the message ID "WM_TOUCH_CHILD" two times, 1st with pMsg->hWinSrc of the graph handler, and 2nd with the button handler, which cause many problems at my code, so I need that when I press the button, just get one time at the message ID "WM_TOUCH_CHILD" , with the with the button handler only, how?


    Thanks

    Hi,

    The behavior of emWin in that case could not be changed. If a window is touched, all ancestors receive that message. A solution could be overwriting the callback function of the GRAPH widget. It receives that message at first before it is also send to the parent of the GRAPH.

    I hope that helps.

    Regards, Jörg
