Dylan Smith c0ee555e8f richedit: Avoid redundant calls to ME_CalcRunExtent.
ME_SplitRun is only called by wrapping code. In all but one call the
returned second half of the split run will be returned, get passed back
to ME_WrapHandleRun, then ME_CalcRunExtent will be called at the start of
ME_WrapHandleRun through ME_WrapSizeRun.

Dylan Smith 4c174fc845 richedit: Removed unused run flags values.
The only place MERF_SKIPPED was in debug code, and MERF_CALCBYWRAP was only
used to clear this unused flag value, so I got rid of both of them.

Dylan Smith 1f2575ba7c richedit: Documented paragraph border widths are in points not pixels.
The border widths documented by msdn are in points which are 72 dpi, which
is not equivalent to pixels (normally 96 dpi). I pre-converted all the
border widths to 96 dpi resolution since this avoids needed to store
fractions, and often avoids the need for convertion to the displays
resolution.

Dylan Smith 0342ab0df1 richedit: Use ITextHost interface in ME_LinkNotify.
Using the ITextHost interface allows this notification to be received
for windowless richedit controls.  Windowed richedit conrols have an
ITextHost implementation that will fill in hwndFrom and idFrom, but
these should probably be initialized to 0 for windowless richedit
controls.

Dylan Smith 1a2ccfe9c7 richedit: Count graphics towards line width.
Images that are inserted into richedit controls store a space for the
text, since that is the character returned when getting the plain text
from the control.

When calculating the width of a line, the space character is skipped,
but images should not be skipped.  This can be seen by inserting an
image into wordpad on a line by it's own, then centering the line.  The
image will start from the center rather than being centered in the
control.

Dylan Smith c8b4455565 richedit: Removed ME_StrRelPos, ME_StrRelPos2, & ME_PosToVPos functions.
These functions were just being used for addition, so it was simpler to
remove the functions and modify the places it was used.

The ME_StrRelPos2 and ME_PosToVPos were just simple wrappers around
ME_StrRelPos, and ME_PosToVPos wasn't being used.

Dylan Smith 5f15de0690 richedit: Removed ME_StrLen and ME_StrVLen field access functions.
These functions were probably previously needed because of some wierd
special handling of backspace characters, but currently there is no
reason why the nLen field can't be accessed directly.

Having to functions that just access the string length field just causes
slightly more effort for someone to look at the code, because they need
to enter the function to find out what it actually is doing.

Dylan Smith e082dd3042 richedit: Add paragraph field to wrap context to avoid searching for it.
More case of searching for the paragraph through the linked list when
is was already previously available.  Since each wrap context is used
for wrapping each paragraph, I decided to add the reference to the
paragarph in the structure.

Dylan Smith 1a3551b630 richedit: Use width from EM_SETTARGETDEVICE for wrapping.
The width for EM_SETTARGETDEVICE is used by some applications to set the
wrapping width to a certain distance in twips.  This can be used even
though the target device is ignored.

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 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.
