描述
get_tshapeget_tshapeGetTshapeGetTshapeGetTshapeget_tshape queries the shape of the text cursor for the
output window. A new cursor shape is set by the operator
set_tshapeset_tshapeSetTshapeSetTshapeSetTshapeset_tshape。
A text cursor marks the current position for text output (which can also
be invisible). It is different from the mouse cursor (although both will
be called ”cursor” if the context makes misconceptions impossible).
The available shapes for the text cursor can be queried with
query_tshapequery_tshapeQueryTshapeQueryTshapeQueryTshapequery_tshape。
