Dylan Smith 05c788ac6f richedit: Used ITextHost methods to avoid using window handle directly.
The methods in ITextHost are mostly thin wrappers around functions that
take a handle to a window as their first parameter.  This patch just
uses the wrapper functions provided by ITextHost instead of using the
functions that require a handle to a window that the editor might now
have (for windowless richedit controls).

Dylan Smith e6fedf879c richedit: Implemented the horizontal scrollbar. 2009-01-15 14:13:38 +01:00
Dylan Smith 97a83147b3 richedit: Avoid re-calculating positions found in wrapping for painting.
When the text is wrapped, the positions for all the runs, paragraphs,
and cells are already calculated and stored.  The only thing left to do
for painting is to offset them by the formatting rectangle and the
scroll position.

Dylan Smith dc03b6b2f2 richedit: Removed redundant editor height variables and calculations.
During wrapping there were three different heights that were being
stored, with only one of them being done correctly.  The other ones
failed to incorporate the height of the paragraph or row, so ended up
being incorrect.

Dylan Smith 297716e01c richedit: Made sure text is offset by formatting rectangle.
The formatting rectangle is set with EM_SETRECT, and retrieved with
EM_GETRECT, so it corresponds to rcFormat in the code.  This defines the
area that the richedit control should draw the text so that it is
offset by the top-left corner of the formatting rectangle, and clipped
so that it doesn't draw past the bottom or right hand side.  Thus this
is important for implementing windowless richedit controls to not
interfere with the rest of the window.

Dylan Smith a32f1f2c1c richedit: Account for selection bar in calculating available width. 2008-10-13 13:17:42 +02:00
Dylan Smith 930f8f5af6 richedit: Removed invalid assertion.
The assertion was not valid, because it neglected to take into account
the situation where a line break is forced with a MERF_ENDROW run
(caused by \line control word or pressing Shift-Enter).  This means
that spaces can cause a line wrap after a forced line break as well as
after a paragraph break, so we cannot assert that it is the first row
in the paragraph.

Dylan Smith e86a1d623a richedit: Fixed regression that caused endless loop. 2008-07-18 11:32:38 +02:00
Dylan Smith db3991257f richedit: Handle overflow of only spaces on first line of paragraph.
The uncommon case that this patch handles is enough whitespace being
on the first line of a paragraph to cause it to wrap.  In this case the
first non-space character will be wrapped onto the next line.

Dylan Smith feda29bb0c richedit: Fixed position of runs in some situations during wrapping.
Runs that are skipped over still need to affect the wrapping position,
otherwise they won't affect further run positions.

Dylan Smith 49468e1824 richedit: Tabs cause lines to wrap but not end of paragraph run. 2008-07-10 18:13:13 +02:00
Dylan Smith e4007e9f97 richedit: Removed redundant wrapping code.
Lines in ME_WrapHandleRun were removed because ME_CalcRunExtent is
already called unconditionally just before it in the call to
ME_WrapSizeRun.

Alex Villacís Lasso 3cc6e2365a richedit: When returning position through wParam pointer, EM_POSFROMCHAR must return 0 as LRESULT.
Add tests for EM_POSFROMCHAR for 1.0 and 2.0.

Dylan Smith 6f11b1b354 richedit: Removed useless code. 2008-05-05 21:18:13 +02:00
Alex Villacís Lasso d2a8461585 richedit: Paragraph may have multiple rows, which should possibly update nHeight.
Otherwise, a paragraph with multiple rows might fail to make the
scrollbar appear when displaying text.
