+LoadFromResourceHandle is an overridden method in TIcon +used to load image data from an icon resource identified by the handles in +Instance and ResHandle. The handles are passed as +arguments to the RTL LoadResource routine which provides the global handle for +the group resource on the platform. +
++LoadFromResourceHandle reads the icon headers and data for the entries from +the resource. The ReadData method is called to read and store the values in +the stream to the shared raster image for the icon. +
++LoadFromResourceHandle reimplements the empty implementation introduced in the +TCustomIcon ancestor. +
++Calls HandleNeeded to ensure that a handle is assigned if it does not already +exist. Calls the ReleaseHandle method in the shared raster image used for the +icon. The return value is the handle for the shared raster image before it is +set to the unassigned value (0). +
++LoadFromResourceHandle is an overridden method in +TCursorImage used to load cursor image(s) from the group cursor +resource identified in the Instance and ResHandle arguments. It calls the RTL +LoadResource routine to get the global handle used for the resource(s) on the +platform. No actions are performed in the method if the handle is unassigned +(0). +
++LoadFromResourceHandle creates a temporary resource stream which is used to +store the group cursor resources, including hot spot and image offset data. +ReadData is called to load the values from the stream to the shared raster +image used for the group cursor resources. +
++LoadFromResourceHandle reimplements the empty implementation introduced in the +TCustomIcon ancestor. +
