Parameters
-
ds Display state text Text expected_width Expected width plen (optional, out) Width of text which fits into
expected_width. Could be NULL.
-
Returns
-
Index of character which breaks the space limit. Returns strlen(text) if whole text fits into
expected_width.
Gets text which fits in expected width without breaking words. Word could be broken in the middle only if single long word is placed on whole line. It means it is possible to get empty string if ds->x is non-zero.

Display text in confined area.
-
Parameters
-
ds Display state x X position width X width text Text from_right (0/1) 1 - end of
text is displayed align_right (0/1) 1 - text is aligned to the right
Current line is used.
Only part of the text is displayed if it doesn't fit into given area. Ellipsis is displayed in place of text omission.
Note that due to implementation limitation the text has to be in RAM.

Determines which part of text fits in expected_width.
-
Parameters
-
ds Display state text Text expected_width Expected width plen (optional, out) Width of text which fits into
expected_width. Could be NULL.
-
Returns
-
Index of character which breaks the space limit. Returns strlen(text) if whole text fits into
expected_width.

Determines which part of text from the end of the string fits in expected_width.
-
Parameters
-
ds Display state text Text expected_width Expected width plen (optional, out) Width of text which fits into
expected_width. Could be NULL.
-
Returns
-
Index of character which breaks the space limit. Returns -1 if whole text fits into
expected_width.
