我是ArcGis中的新成員。我遇到了需要在ArcGis工具欄上使用命令的要求。點擊該命令後,Windows窗體將打開並出現一個區域選擇器按鈕。點擊按鈕後,當前的表單用戶界面必須最小化,用戶將被允許繪製一個多邊形。你能幫助如何做到這一點。這是代碼。我採取了正常的窗口按鈕,並在點擊事件中寫下了下面的代碼。如何在窗體中添加arcgis按鈕
_application = ((IApplication)_hookHelper.Hook);
IMxDocument pMxDoc = (IMxDocument)_application.Document;
IMap pMap = (IMap)pMxDoc.FocusMap;
IActiveView pActiveView = (IActiveView)pMap;
if (pActiveView == null)
{
return;
}
//// Changing the state of the Window.
if (this.WindowState == FormWindowState.Normal || this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Minimized;
// this.Hide();
}
ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = pActiveView.ScreenDisplay;
// Constant
screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
ESRI.ArcGIS.Display.IRgbColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();
rgbColor.Blue = 111;
ESRI.ArcGIS.Display.IColor color = rgbColor; // Implicit Cast
ESRI.ArcGIS.Display.ISimpleFillSymbol simpleFillSymbol = new ESRI.ArcGIS.Display.SimpleFillSymbolClass();
simpleFillSymbol.Color = color;
ESRI.ArcGIS.Display.ISymbol symbol = simpleFillSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberRectangularPolygonClass();
// ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberPolygonClass();
ESRI.ArcGIS.Geometry.IGeometry geometry = rubberBand.TrackNew(screenDisplay, symbol);
screenDisplay.SetSymbol(symbol);
screenDisplay.DrawPolygon(geometry);
screenDisplay.FinishDrawing();
我也沒有得到任何鼠標事件,並且UI在開始繪製多邊形時沒有最小化。任何人都可以請幫忙。
