Because companies need to do A small camera project, the new contact minigui, run on the board, met the following such A problem: there are two Windows. A, B, is the main window to the parent window, main is to call A camera related operations, window without interface, separate from the main window to enter A window can display the camera, normal pull Dialog prompt can insert SD card do normal display and destruction, but from B window call A window, video image display properly, but A window above need to be able to Show or hide A few little control, the video images are below A window interface (similar to the video player that effect), these small controls are based on the B window is created, but small controls at this point but not in hiding after the Show come out, hide or Destroy interface has been left on the screen, is like painting on paper, can only draw up, but don't rub off, it makes me very confusing, so come to seek minigui great god help, thank!!!!!! Or you can give other implementation suggestion, they can achieve that kind of effect (similar to the function of the player interface effect),
