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

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;
}
