While dragging an icon across multiple pages, often times, the icon being dragged gets stuck.



  • I have created one application where there are multiple icons present in a GridView. Each delegate of the grid is a composite control with an icon and some text (similar to phones icons screen).
    And like a phones main screen, user can drag and drop icons across multiple pages of the gridview.
    There are navigation buttons on the right and left side of the icons grid, when an icon is dragged on top of the navigation buttons, the page scrolls left OR right to display the corresponding grid of apps.
    While dragging an icon across multiple pages, often times, the icon being dragged gets stuck.

    Initially I could duplicate this issue easily, but I found one solution in increasing the cacheBuffer for GridView. Current value for cacheBuffer is 100000.
    While this has reduced the frequency with which the issue was reproduced. It has not got fixed completely.

    If anyone is aware of this problem please suggest some solution. I am using QT 5.3.2 on QNX Neutrino 6.6.
