Lição eletrônica interativa do desenvolvimento de sistema de Big Data da caixa de areia de Digitas 8
A função que completamos desta vez é arrastar um objeto de UI externo para a bola:
private void Button_PreviewMouseMove(object sender, MouseEventArgs e)
{ if(e.LeftButton== MouseButtonState.Pressed) DragDrop.DoDragDrop((Button)sender, sender, DragDropEffects.Move);< a i=4> } private void Gis3d_PreviewDrop(object sender, DragEventArgs e) { if (e.Data.GetData(typeof(Button)) != null) { MTGIS3D Pareant = ((MTGIS3D)IniRead.IniReadWrite.MPareant); GisLib.GIS2D.UserCanvas y1 = new GisLib.GIS2D.UserCanvas(); JuLiSechBiao.AutoAngle = true;//是否自动角度，使终对着摄像机 JuLiSechBiao. AutoScal = true;//是否自动缩放，不管在哪一层都是一样大 JuLiSechBiao.Scal.ScaleZ = 1; JuLiSechBiao.Scal.ScaleY = 1; JuLiSechBiao.Scal.ScaleX = 1; //固定东东 JuLiSechBiao.ZScal = 0,6;//相对缩放 JuLiSechBiao.DHi = 0,01;//相对于地形的高度 JuLiSechBiao.MUIValue = Y1;//UI对象 JuLiSechBiao.MaxZoom = 9;//最大显示层,当小于9层的时候不显示 JuLiSechBiao.Manage = IniRead.IniReadWrite.BiaoManage;//设置它的标号管理器 JuLiSechBiao.PareantEarth = (NewGisBiao.Base.GISInterfaseForBiao)IniRead.IniReadWrite.MPareant;//设置它的GIS球对象 NewGisBiao.M3D.UserGisUI3dObject2 JuLiSechBiao = new NewGisBiao.M 3D.UserGisUI3dObject2() ; //新建一个承载UI对象的东东 Y1.Height = Data.Height; Y1.Width = Data.Width; Y1.Content=Data.Content; Botão Y1 = new Button(); Dados do botão = (botão)e.Data. GetData(typeof(Button)); Point3D va = ((MTGIS3D)IniRead.IniReadWrite.MPareant).GetJWForMouse(e.GetPosition(Pareant)); JuLiSechBiao.MWidth = Data.Width;//三维面片的大小 JuLiSechBiao.MHeight = Data.Height; if (IniRead.IniReadWrite.MPareant is MTGIS3D) //手动刷新一下自动角度。。。bug } JuLiSechBiao.ISShow = true;//显示 JuLiSechBiao.Center = new Point(va.X, va.Y);//设置中心点 } ((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxis). ÂnguloX.Ângulo -= 0,001; ((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxisAngleX.Angle += 0,001; {
}
