detach_drawing_object_from_windowT_detach_drawing_object_from_windowDetachDrawingObjectFromWindowDetachDrawingObjectFromWindowdetach_drawing_object_from_window从窗口中分离绘图对象（算子）

名称

detach_drawing_object_from_windowT_detach_drawing_object_from_windowDetachDrawingObjectFromWindowDetachDrawingObjectFromWindowdetach_drawing_object_from_window — 从 HALCON 窗口中分离现有图形对象。

签名

detach_drawing_object_from_window( : : WindowHandle, DrawHandle : )

描述

此算子可用于将绘图对象 DrawHandleDrawHandleDrawHandleDrawHandledrawHandledraw_handle 从其当前关联的 HALCON 窗口 WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle 上解除关联。该绘图对象将不再显示在窗口中。如果此前已通过 set_drawing_object_callbackset_drawing_object_callbackSetDrawingObjectCallbackSetDrawingObjectCallbackSetDrawingObjectCallbackset_drawing_object_callback 为该绘图对象在 “on_detach” 或 “on_select” 事件上定义了回调函数，则该回调函数也将被调用。

执行信息

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle (输入控制) window → (handle)

窗口句柄。

DrawHandleDrawHandleDrawHandleDrawHandledrawHandledraw_handle (输入控制) drawing_object → (handle)

绘图对象的句柄。

结果

detach_drawing_object_from_windowdetach_drawing_object_from_windowDetachDrawingObjectFromWindowDetachDrawingObjectFromWindowDetachDrawingObjectFromWindowdetach_drawing_object_from_window 返回 2 (H_MSG_TRUE)，如果 DrawHandleDrawHandleDrawHandleDrawHandledrawHandledraw_handle 和 WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle 有效。否则将抛出异常。
