已修改事件
大家好,我从autocad帮助中复制了这段代码,但是想要创建一个带有句柄
的对象的事件,一个独立于其他子的事件,可以在autocad启动时使用,或者任何时候
我想创建一个具有一些句柄的数据库,并且当我更改一个特定的对象时, 太换了数据库,一个动态数据库
对不起我的英文,不是很好。
来自 Autocad 帮助的代码:
Public WithEvents PLine As AcadLWPolyline ' Use with Modified Event Example
Sub Example_Modified()
' This example creates a lightweight polyline in model space and
' references the PolyLine using the public variable (PLine) which
' is set up to intercept Modified events.
'
' This example then modifies the new object, triggering the code
' in the Modified event.
Dim points(0 To 9) As Double
' Define the 2D polyline points
points(0) = 1: points(1) = 1
points(2) = 1: points(3) = 2
points(4) = 2: points(5) = 2
points(6) = 3: points(7) = 2
points(8) = 4: points(9) = 4
' Create a lightweight Polyline object in model space
'
' * Note: We are returning the new PolyLine object into a Module
' level variable.This allows us to intercept events associated
' with that particular object.
Set PLine = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
ThisDrawing.Application.ZoomAll
' Modify object to trigger event.
'
' * Note: The event code for the PolyLine modification will be triggered
' before we move forward and refresh the view, so the line will not
' appear blue when the event message box is displayed.
Dim color As AcadAcCmColor
Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.20")
Call color.SetRGB(80, 100, 244)
PLine.TrueColor = color
ThisDrawing.Regen acAllViewports
End Sub
Private Sub PLine_Modified(ByVal pObject As AutoCAD.IAcadObject)
' This example intercepts an object's Modified event.
'
' This event is triggered when an object supporting this event is modified.
'
' To trigger this code: Modify an object connected to this event
' * Note: By connected, we mean the object set up to intercept events using
' the VBA WithEvents statement
' Use the "pObject" variable to determine which object was modified
MsgBox "You just modified an object with an ID of: " & pObject.ObjectID
End Sub
