Method Documentation

onMapFeaturePickComplete:screenPosition:

- (void) onMapFeaturePickComplete:		(nonnull NSDictionary< NSString *, NSString * > *)	mapFeaturePickResult
screenPosition:		(CGPoint)	screenPosition

Receive the result from LocationWindow pickMapFeatureAt

Parameters

mapFeaturePickResult	dictionary of properties of the picked feature or nil if no objects was found.
screenPosition	position where the object was picked in pixels.

Swift code snippet:

    func onMapFeaturePickComplete(mapFeaturePickResult: [String: String]?, screenPosition: NCPoint) {
        if let result = mapFeaturePickResult {
            print("Map feature picked at screen position (\‍(screenPosition.x), \‍(screenPosition.y))")
            print("  Feature properties: \‍(result)")
        } else {
            print("No map feature found at screen position (\‍(screenPosition.x), \‍(screenPosition.y))")
        }
    }

Objective C code snippet:

- (void)onMapFeaturePickCompleteWithMapFeaturePickResult:(NSDictionary<NSString *, NSString *> *)mapFeaturePickResult screenPosition:(NCPoint *)screenPosition {
    if (mapFeaturePickResult != nil) {
        NSLog(@"Map feature picked at screen position (%.1f, %.1f)", screenPosition.x, screenPosition.y);
        NSLog(@"  Feature properties: %@", mapFeaturePickResult);
    } else {
        NSLog(@"No map feature found at screen position (%.1f, %.1f)", screenPosition.x, screenPosition.y);
    }
}

onMapObjectPickComplete:screenPosition:

- (void) onMapObjectPickComplete:		(nullable NCMapObjectPickResult *)	mapObjectPickResult
screenPosition:		(CGPoint)	screenPosition

Receive the result from LocationWindow pickMapObjectAt method.

Parameters

mapObjectPickResult	MapObjectPickResult instance or nil if no objects was found.
screenPosition	position where the object was picked in pixels.

Swift code snippet:

    func onMapObjectPickComplete(mapObjectPickResult: NCMapObjectPickResult?, screenPosition: NCPoint) {
        if let result = mapObjectPickResult {
            // [swift_MapObjectPickResult_getPoint]
            let point = result.point
            print("Map object picked at screen position (\‍(screenPosition.x), \‍(screenPosition.y))")
            print("  Object location: (\‍(point.x), \‍(point.y))")
            // [swift_MapObjectPickResult_getPoint]
            
            // [swift_MapObjectPickResult_getMapObject]
            let mapObject = result.mapObject
            print("  Object type: \‍(type(of: mapObject))")
            // [swift_MapObjectPickResult_getMapObject]
        } else {
            print("No map object found at screen position (\‍(screenPosition.x), \‍(screenPosition.y))")
        }
    }

Objective C code snippet:

- (void)onMapObjectPickCompleteWithMapObjectPickResult:(NCMapObjectPickResult *)mapObjectPickResult screenPosition:(NCPoint *)screenPosition {
    if (mapObjectPickResult != nil) {
        // [objc_MapObjectPickResult_getPoint]
        NCLocationPoint *point = mapObjectPickResult.point;
        NSLog(@"Map object picked at screen position (%.1f, %.1f)", screenPosition.x, screenPosition.y);
        NSLog(@"  Object location: (%.1f, %.1f)", point.x, point.y);
        // [objc_MapObjectPickResult_getPoint]
        
        // [objc_MapObjectPickResult_getMapObject]
        NCMapObject *mapObject = mapObjectPickResult.mapObject;
        NSLog(@"  Object type: %@", NSStringFromClass([mapObject class]));
        // [objc_MapObjectPickResult_getMapObject]
    } else {
        NSLog(@"No map object found at screen position (%.1f, %.1f)", screenPosition.x, screenPosition.y);
    }
}
