send_mouse_drag_eventsend_mouse_drag_eventSendMouseDragEventSendMouseDragEventSendMouseDragEvent sends an event
at the position (RowRowRowRowrow, ColumnColumnColumnColumncolumn) to the buffer window
WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle, signaling that the mouse button encoded by
ButtonButtonButtonButtonbutton is been dragged. Please refer to
get_mbuttonget_mbuttonGetMbuttonGetMbuttonGetMbutton to see how to encode ButtonButtonButtonButtonbutton.
If the event could be processed, send_mouse_drag_eventsend_mouse_drag_eventSendMouseDragEventSendMouseDragEventSendMouseDragEvent returns
'true'"true""true""true""true" in ProcessedProcessedProcessedProcessedprocessed. If no action for the event could be
determined (e.g., because there is no drawing object below the mouse
position), 'false'"false""false""false""false" is returned in ProcessedProcessedProcessedProcessedprocessed. In this case
the caller may determine an action for the event.

send_mouse_drag_eventsend_mouse_drag_eventSendMouseDragEventSendMouseDragEventSendMouseDragEvent and send_mouse_double_click_eventsend_mouse_double_click_eventSendMouseDoubleClickEventSendMouseDoubleClickEventSendMouseDoubleClickEvent are
the only means to manipulate drawing objects in buffer windows.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Window handle of the buffer window.
Row coordinate of the mouse cursor in the image
coordinate system.
Column coordinate of the mouse cursor in the image
coordinate system.
'true', if HALCON processed the event.
send_mouse_drag_eventsend_mouse_drag_eventSendMouseDragEventSendMouseDragEventSendMouseDragEvent returns the value 2 (H_MSG_TRUE) if the window
handle WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle corresponds to a window of valid type, and the
event is properly encoded. Otherwise, an exception is raised.
