Description

Often you need to instance Hooks, and keep the Hook pointer, but you don't actually need the Hook itself (just the memory should be remembered). The easiest way is to use this class for bookkeeping opened Hooks.

Example:

var
  Hook: PHook;
begin
  Hook := HookList.GetNewHook;        // get a new Hook Pointer
  MH_SetHook(Hook^, PressFunc, Self); // set the Hook fields
  //Connect the Hook to the Pressed property of Area
  DoMethod(ButtonObj, [MUIM_Notify, MUIA_Pressed, AsTag(False), AsTag(AObj), 2, MUIM_CallHook, AsTag(Hook)]);
  // you do not need to keep the Hook anymore, it will be destroyed on HookList.destroy
end;
