ArcGIS Engine 開發學習-------基礎(一):自定義命令
阿新 • • 發佈:2018-12-02
要求:在ToolbarControl中新增一個自定義命令,點選可清除當前活動工具。
步驟:
1、建立GIS類,選擇Base Command模版,Extending ArcObjects,ArcMap MapControl or PageLayoutControl command,命名為ClearCurrentActiveToolCmd.cs
2、在類中定義IToolbarControl的介面變數m_ToolbarControl,並在類的建構函式中改變所繼承的基類屬性,其中,base.m_bitmap,即該命令的圖示可直接雙擊本工程中的ClearCurrentActiveToolCmd.bmp修改。
3、在OnCreate過載函式中,將Hook轉換為IToolbarControl,並賦給m_ToolbarControl變數。
4、在OnClick過載函式中,將m_ToolbarControl介面變數的CurrentTool屬性設定為空。
程式碼如下:
using System; using System.Drawing; using System.Runtime.InteropServices; using ESRI.ArcGIS.ADF.BaseClasses; using ESRI.ArcGIS.ADF.CATIDs; using ESRI.ArcGIS.Controls; namespace WindowsFormsApplication2_1_2 { /// <summary> /// Summary description for ClearCurrentActiveToolCmd. /// </summary> [Guid("df41e943-e173-4d88-90c1-52d7230ca74a")] [ClassInterface(ClassInterfaceType.None)] [ProgId("WindowsFormsApplication2_1_2.ClearCurruntActiveToolCmd")] public sealed class ClearCurrentActiveToolCmd : BaseCommand { #region COM Registration Function(s) [ComRegisterFunction()] [ComVisible(false)] static void RegisterFunction(Type registerType) { // Required for ArcGIS Component Category Registrar support ArcGISCategoryRegistration(registerType); // // TODO: Add any COM registration code here // } [ComUnregisterFunction()] [ComVisible(false)] static void UnregisterFunction(Type registerType) { // Required for ArcGIS Component Category Registrar support ArcGISCategoryUnregistration(registerType); // // TODO: Add any COM unregistration code here // } #region ArcGIS Component Category Registrar generated code /// <summary> /// Required method for ArcGIS Component Category registration - /// Do not modify the contents of this method with the code editor. /// </summary> private static void ArcGISCategoryRegistration(Type registerType) { string regKey = string.Format("HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID); ControlsCommands.Register(regKey); } /// <summary> /// Required method for ArcGIS Component Category unregistration - /// Do not modify the contents of this method with the code editor. /// </summary> private static void ArcGISCategoryUnregistration(Type registerType) { string regKey = string.Format("HKEY_CLASSES_ROOT\\CLSID\\{{{0}}}", registerType.GUID); ControlsCommands.Unregister(regKey); } #endregion #endregion private IHookHelper m_hookHelper; private IToolbarControl m_ToolbarControl; public ClearCurrentActiveToolCmd() { // // TODO: Define values for the public properties // base.m_category = "Custom Command"; //localizable text base.m_caption = "清除當前活動工具"; //localizable text base.m_message = "清除當前活動工具"; //localizable text base.m_toolTip = "清除當前活動工具"; //localizable text base.m_name = "清除當前活動工具"; //unique id, non-localizable (e.g. "MyCategory_MyCommand") try { // // TODO: change bitmap name if necessary // string bitmapResourceName = GetType().Name + ".bmp"; base.m_bitmap = new Bitmap(GetType(), bitmapResourceName); } catch (Exception ex) { System.Diagnostics.Trace.WriteLine(ex.Message, "Invalid Bitmap"); } } #region Overridden Class Methods /// <summary> /// Occurs when this command is created /// </summary> /// <param name="hook">Instance of the application</param> public override void OnCreate(object hook) { if (hook == null) return; if (m_hookHelper == null) m_hookHelper = new HookHelperClass(); m_hookHelper.Hook = hook; // TODO: Add other initialization code } /// <summary> /// Occurs when this command is clicked /// </summary> public override void OnClick() { if (m_hookHelper.Hook is IToolbarControl) { m_ToolbarControl = m_hookHelper.Hook as IToolbarControl; m_ToolbarControl.CurrentTool = null; } // TODO: Add ClearCurruntActiveToolCmd.OnClick implementation } #endregion } }
5、在Form1.cs的窗體load事件中新增程式碼,將該命令新增到toolstrip上。
axToolbarControl1.AddItem(new ClearCurrentActiveToolCmd(), -1, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly);
