— Set the position of the text cursor.
Signature
Description
set_tpositionset_tpositionSetTpositionSetTpositionSetTpositionset_tposition
sets the position of the text cursor in the
output window. The reference position is the upper left corner of an
upper case character.
The position is measured in the image coordinate system. The
position of the text cursor can be marked, e.g., by an underscore.
The next text output in this window starts at the cursor position.
The left end of the baseline for writing the following text 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
). In order
to stop the display of the cursor, the operator set_tshapeset_tshapeSetTshapeSetTshapeSetTshapeset_tshape
with the parameter ”invisible” can be used.
