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.
The parent window for the richedit control on creation is the one that
receives notify messages, even after the parent has been changed using
SetParent.
The function was used in one place, and was simply a wrapper around a
call to ME_InsertRunAtCursor, so I removed it to avoids it use in other
parts of the code.
Previously the function was only used to move a single character in
either direction, so I made the function more general so that it could
be used in more places.
The test that succeeded from this change was as a result of allowing the
end of the character format change be specified using NULL as the rest
of the text. Before, the end paragraph run at the end of the text was
not being set for this case, when all the text was supposed to have its
character format changed.
Plenty of places in the code find following or preceding runs, then
afterwards find the paragraph from the run. This is inefficient because
the same linked list is used for both runs and paragraphs, so changes in
paragraphs can be detected while returning the next or previous run.
Before a single length was used for the number of characters to retrieve
from the text, and to keep track of the size of the buffer. These are
not equivalent, since there is a possible end of line conversion.
Previously the only convenient way to get the start and end of the
selection was through offsets, which eventually need to get converted
back into items in the linked list storing the text. The new function
will help with eliminating these inefficiencies.
This function will make it easier to work with ME_Cursor objects, which
should be used in a lot of places instead of character offsets (which
often require seeking through the linked lists to perform operations
with).
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.
These two functions were being used for simple operations, to get the
first or last character when pre-computing flags for splitting runs.
The call to ME_GetCharBack wasn't even giving the correct result, it
would always return -1 since it is being called with nPos of 0.
This patch simplifies the code by removing the functions and getting the
characters directly from the string.
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.
The function was just returning the second parameter. It had some
commented out code that indicated that previously backslashes weren't
included in the length. Native wordpad doesn't handle backspaces in a
special way, so this must have been an internal representation that
complicated finding the position of characters.
I found that ME_MakeStringB was previously unused, and that the other
ME_MakeString functions repeated code that was already in ME_MakeStringB.
Making ME_MakeStringB static and using it to avoid duplicate code seemed
like a better idea than removing the function.
