Robert O'Callahan 71a8a74b43 Fixed bug in TEXT_WordBreak that was variously throwing Lotus Notes
into an infinite loop or causing it to crash.

Alexandre Julliard 5769d1de00 Better support for configure detection of missing types, added check
for ssize_t.
Removed a couple of no longer used portability functions.
Various portability fixes in port.h.

Add protection to prevent reading outside the buffer.
Better handling of degenerate cases.

Bill Medland bc39eeec40 Correct Word breaking in centred/right justified mode; it was leaving a
trailing space which it should only do for left-justified text.
Also tighten up some comments.

Bill Medland 7423dc0463 DrawText ellipsification on all lines, not just single-line. 2002-02-21 20:07:26 +00:00
Bill Medland 8513907f2c Drawtext tidying up ready for the next big change:
- Fix brainfade in previous delta
- Move ellipsification results to static memory; they are going to
  have to be referenced inside NextLineW and the arg list is too big
  already.
- Add the missing ellipsification result (len_under) to simplify coding.
- Slight correction to prefix tracking for when there are several
  underlined characters on a single line (DT_EXPANDTABS only).
- Allocate and free the temporary copy required for DT_MODIFYSTRING
  rather than using a fixed size stack array.
- Introduce lastline into the main loop; it simplifies the code and we
  are going to need it.

Bill Medland 7af9098f6b Change the way that DrawText parses the next line to display, ready to
support multiline ellipsification etc.  Rather than measuring the text
each time we add a character and breaking once it is too long and
WORDBREAK is enabled, we copy a whole text segment and then measure
it; GetTextExtentPointEx is designed to tell us how much fitted.  This
may result in a little rescanning if wordbreak is enabled but will be
well worth while when multiline path ellipsification is brought down
into the NextLine function.  Note also that the wordbreak calculation
is a little more complete (e.g.  including break-within-word for
DT_EDITCONTROL).

Bill Medland 0f9013f7e0 Measure the text more reasonably. This handles intercharacter spacing
and should handle any kerning etc. that might happen. Also ensure no
wordbreaking on singleline text.

Bill Medland 92d77c9bb2 DrawText should not split words just because of clipping. 2002-02-14 19:21:59 +00:00
Bill Medland cabe8ca580 Put in place a proper tab model within DrawText (also includes
simplifying TEXT_NextLineW to remove duplicate code).
2002-02-12 18:40:36 +00:00
Bill Medland afe92e8e8a Split the path and word/end ellipsification out of the main function
and do them thoroughly. The existing method would be incorrect where
tabs were involved and in some kerning situations.
2002-02-05 18:07:04 +00:00
Bill Medland fdb799aa6a Ensure that the whole modified text is returned from DrawTextExA. 2002-02-02 18:14:35 +00:00
Bill Medland 001e732c41 - Introduce a significant design decision.
- Recalculate the prefix location if ellipsification alters it.  This
  carefully does NOT emulate a Microsoft bug in which reprefixing is
  wrong when the first character removed by ellipsification is the one
  that would have been underlined (under Win98 at least).
2002-01-31 20:44:39 +00:00
Bill Medland a4605ac000 Put the prefix-underline-drawing away into it's own function so we can
see what is happening.
2002-01-29 02:46:09 +00:00
Bill Medland fcb8e0d77a - Don't string copy from uninitialised stack memory. In fact don't
modify the input string if it didn't change.
- Correct array size.
- Logically separate the centring from the ellipsification.
- Comment on prefix error.
2002-01-18 18:09:09 +00:00
Bill Medland fd59f34ec0 First stage of DrawText upgrade.
- Rearrange code into three distinct areas; DrawText, GrayString,
  TabbedText.
- Remove unused macros.
- Modify treatment of Tab arguments to fit with observed behaviour.
  e.g. DrawTextEx with DT_TABSTOP but null dtp will not take the
  setting from the flags.  Also only uses bits 15 to 8, not the
  higher bits.
