send_mouse_double_click_eventsend_mouse_double_click_eventSendMouseDoubleClickEventsend_mouse_double_click_eventSendMouseDoubleClickEventSendMouseDoubleClickEvent sends an event
at the position (RowRowRowRowRowrow, ColumnColumnColumnColumnColumncolumn) to the buffer window
WindowHandleWindowHandleWindowHandleWindowHandleWindowHandlewindowHandle, signaling that the mouse button encoded by
ButtonButtonButtonButtonButtonbutton has been double clicked. Please refer to
get_mbuttonget_mbuttonGetMbuttonget_mbuttonGetMbuttonGetMbutton to see how to encode ButtonButtonButtonButtonButtonbutton.
The purpose of this operator is to select a drawing object in a
situation where multiple drawing objects are stacked on top of each
other in a buffer window. If the double click happens on either one
of the markers of the object border of the active object the object
below is selected. To simplify the interaction with the drawing
object, the coordinates RowRowRowRowRowrow and ColumnColumnColumnColumnColumncolumn are given in
the image coordinate system. To convert window coordinates into
image coordinates, the operator
convert_coordinates_window_to_imageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImage can be used.
If the event could be processed, send_mouse_double_click_eventsend_mouse_double_click_eventSendMouseDoubleClickEventsend_mouse_double_click_eventSendMouseDoubleClickEventSendMouseDoubleClickEvent returns
'true'"true""true""true""true""true" in ProcessedProcessedProcessedProcessedProcessedprocessed. 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""false" is returned in ProcessedProcessedProcessedProcessedProcessedprocessed. In this case
the caller may determine an action for the event.

might not be available on embedded systems.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
