get_tpositionT_get_tpositionGetTpositionGetTpositionget_tposition (Operator)
Name
get_tpositionT_get_tpositionGetTpositionGetTpositionget_tposition — Get cursor position.
Signature
Description
get_tpositionget_tpositionGetTpositionGetTpositionGetTpositionget_tposition queries the current position of the text
cursor in the output window. The position is measured in the image
coordinate system. The next output of text in this window starts at
the cursor position. The left end of the baseline for writing the
next string (not considering descenders) is placed on this
position. The position is changed by the output or input of text
(write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string, read_stringread_stringReadStringReadStringReadStringread_string) or by an explicit change
of position by (set_tpositionset_tpositionSetTpositionSetTpositionSetTpositionset_tposition, new_linenew_lineNewLineNewLineNewLinenew_line).
Attention
If the output text does not fit completely into the window, an exception is
raised. This can be avoided by
set_check('~text')set_check("~text")SetCheck("~text")SetCheck("~text")SetCheck("~text")set_check("~text").
