hi, could anyone please explain how an array of Handlers is defined? void Handler(int, int); struct WData { POINTS mouse; // Current location of the mouse Queue clicks[WM_MOUSELAST - WM_MOUSEFIRST + 1]; // Array to hold the coordinates of the clicks int mouse_queuing[WM_MOUSELAST - WM_MOUSEFIRST + 1]; // Array to tell whether mouse events should be queued Handler mouse_handlers[WM_MOUSELAST - WM_MOUSEFIRST + 1]; // Array of mouse event handlers int refreshing; // True if autorefershing should be done after each drawing event }; how is that: Handler mouse_handlers[WM_MOUSELAST - WM_MOUSEFIRST + 1] translated to D? thank you |

Posted in reply to hr | try: Handler[] mouse_handlers = new [WM_MOUSELAST - WM_MOUSEFIRST + 1] or if the size is statically known: Handler[WM_MOUSELAST - WM_MOUSEFIRST + 1] handler; |

Thank you for your help.
after doing what you propose, i get the error message:
Error 1 Error: function Handler is used as a type
void Handler(int, int); is function prototype.
any other suggestions?

This works for me:
void handler(int a, int b) {} ;
void main()
{
alias void function(int, int) Handler;
Handler[] handlers = new Handler[12];
handlers[0] = &handler;
}
