Dylan Smith 5f51221d9c richedit: Fixed scrollbar visiblility calculation after SetScrollInfo.
The scrollbar visibility can be changed from SetScrollRange or
SetScrollInfo, but the visiblity that is a result of these calls are
not consistent with the calculation made by richedit controls to
decide whether to show or hide the scrollbars.

Dylan Smith a0466e2c0e richedit: Don't show vertical scrollbar for single line controls.
The vertical scrollbar is not shown when the ES_MULTILINE style isn't
used, unless ES_DISBALENOSCROLL is also used.

Dylan Smith ecb6c2169c richedit: Store paragraph in cursors.
This prevents some needless searching for the start of the paragraph
from a run stored in a cursor.  Usually a pointer to the paragraph is
already available when the cursor is set anyway.

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 5c91d5356e richedit: Avoided searching for adjacent paragraphs through runs.
When finding an adjacent paragraph, the next_para and prev_para pointers
should be used because they are direct pointers, a constant time
operation.  Instead I found some places in the code that searched through
the general linked list to get to an adjacent paragraph, which is a linear
time operation, depending on the number of rows and runs in between
paragraphs.

Dylan Smith ea9e062b6c richedit: Removed unnecessary calls to ME_WrapMarkedParagraphs.
These calls to ME_WrapMarkedParagraphs never do anything, and don't make
sense to be called in these places. These places are for ME_MoveCaret,
and ME_ArrowHome, which both don't involve any text being modified, and
all (direct and indirect) calls to these functions are done after the
text has already been wrapped.

Marcus Meissner 43eb9ab9d7 riched20: rcUpdate cannot be NULL in ME_PaintContent (Coverity). 2009-01-28 12:30:43 +01:00
Dylan Smith a051a23119 richedit: Suppress scrollbar if missing WS_[VH]SCROLL style.
If the scrollbar style isn't initially used, then the scrollbar should
be shown.  Otherwise this can be a problem when the horizontal scrollbar
is shown for a single line richedit control, since it will cover all the
text (See bug 12088).

Dylan Smith 5d74f58382 richedit: Actually store end of line string for end paragraph runs.
Previously a count of the carraige returns and line feeds were stored
for end of paragraph runs, and a paragraph sign was stored as the actual
string.  This was causing many special cases where the length of the
run needed to be determined differently if the run was or wasn't an
end of paragraph run.

There wasn't any use for storing the paragraph sign unless some drawing
code gets commented out to allow the end paragraphs to be shown,
therefore I changed the code to store the actual string that gets
retrieved by WM_GETTEXT.

Dylan Smith 94146a72ad richedit: Removed some unused invalidation code.
The ME_InvalidateFromOfs and ME_QueueInvalidateFromCursor functions are
never called, and the nInvalidOfs variable had its value set but never
used.

Dylan Smith 902afbc65b richedit: Prevented using NULL hwnd for certain operations.
Certain operations will simply not be done for windowless richedit
controls, such as WM_PAINT which isn't done for windowless richedit
controls since ITextServices provides a TxDraw method.
2009-01-21 11:55:03 +01:00
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 6df4148b04 richedit: Prevent redundant rewraps when scrollbar is shown.
A common case for richedit controls are that a large amount of text is
set initially with word wrap enabled.  This causes the initially
wrapping of the text, which also calculates the text length.  After
this the vertical scrollbar will be shown, which causes the text to be
rewrapped again.  After this there are two redundant rewraps that are
done which this patch eliminates.

Dylan Smith a16db0afc6 richedit: Scroll up with less than page of text with ES_DISABLENOSCROLL. 2009-01-06 12:51:41 +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.
2008-12-20 11:43:29 +01:00
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.
2008-12-20 11:43:09 +01:00
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.

the text using system colours for the background and the text.
