Question

我尝试实现可通过使用ThinkGeo绘制地图的鼠标单击事件。当我开始运行代码时，此功能才处于活动状态。我想在地图上应用一个按钮，以便可以启用和禁用地图上的鼠标单击事件。有人可以显示一个示例或示例，我认为它需要布尔类型变量对吗？

 private void map_Loaded(object sender, RoutedEventArgs e)
        {
            Map1.MapUnit = GeographyUnit.Meter;
            LayerOverlay myOverlay = new LayerOverlay();
            Map1.Overlays.Add(myOverlay);

            myOverlay.TileCache = new FileBitmapTileCache(@"..\..\Cache\");

            string[] files = System.IO.Directory.GetFiles(@"C:\Users\User\Desktop\DSI REFERENCE\Map Data\Raster");

            foreach (string file in files)
            {
                GeoTiffRasterLayer tiffLayer = new GeoTiffRasterLayer(file);

                myOverlay.Layers.Add(tiffLayer);
            }
            myOverlay.Open();
            Map1.CurrentExtent = myOverlay.GetBoundingBox();

            InMemoryFeatureLayer inmemoryFeatureLayer = new InMemoryFeatureLayer();
            inmemoryFeatureLayer.ZoomLevelSet.ZoomLevel01.DefaultPointStyle = new PointStyle(new GeoImage(@"C:\Users\User\Downloads\15floors\Icon\Point.png"));
            inmemoryFeatureLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;

            LayerOverlay markerOverlay = new LayerOverlay();
            markerOverlay.Layers.Add(inmemoryFeatureLayer);
            Map1.Overlays.Add("MarkerOverlay", markerOverlay);

            Map1.Refresh();
        }

        private void Map1_MapClick(object sender, MapClickWpfMapEventArgs e)
        {

            LayerOverlay markerOverlay = (LayerOverlay)Map1.Overlays["MarkerOverlay"];
            InMemoryFeatureLayer inmemoryFeatureLayer = markerOverlay.Layers[0] as InMemoryFeatureLayer;

            MultipolygonShape buffer = e.WorldLocation.Buffer(350, GeographyUnit.Meter, DistanceUnit.Kilometer);

            inmemoryFeatureLayer.InternalFeatures.Add(new Feature(e.WorldLocation));




            Map1.Refresh();
        }

        private void Plot_ButtonClick(object sender, RoutedEventArgs e)
        {

                InMemoryFeatureLayer inMemoryLayer = (InMemoryFeatureLayer)Map1.FindFeatureLayer("InMemoryFeatureLayer");
                inMemoryLayer.Open();
                inMemoryLayer.EditTools.BeginTransaction();
                inMemoryLayer.EditTools.Delete("MarkerOverlay");
                inMemoryLayer.EditTools.CommitTransaction();
                inMemoryLayer.Close();


                Map1.Refresh(Map1.Overlays["InmemoryOverlay"]);

        }

    }

无需创建按钮，如果您不希望地图控件生成鼠标单击事件，则只需关闭点击测试：

Map1.IsHitTestVisible = false;
