Marcus Meissner 43eb9ab9d7 riched20: rcUpdate cannot be NULL in ME_PaintContent (Coverity). 2009-01-28 12:30:43 +01:00
Dylan Smith f42e151a6c richedit: Updated internal style flags on EM_SHOWSCROLLBAR.
The internal style flags are used to determine whether to show or hide
the scrollbar when ME_UpdateScrollBar is called.  EM_SHOWSCROLLBAR seems
to update this state in native richedit controls.

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 61308257f2 richedit: Removed redundant ME_FindItemAtOffset using ME_RunOfsFromCharOfs.
The two functions ME_FindItemAtOffset and ME_RunOfsFromCharOfs were almost
identically used, since ME_FindItemAtOffset was always used to find a run.
The only difference was how they returned the offset within the run for an
end of paragraph run.

For ME_FindItemAtOffset it would return the next run if it was in between \r
and \n. ME_RunOfsFromCharOfs would instead return an nOffset of 0 for end
paragraph runs.  This subtle difference introduced bugs, so I decided to
avoid having special case in this function when creating this patch, and
instead let the caller handle this case.

Dylan Smith 61f189cec8 richedit: Handle starting in EOL sequence in EM_GETTEXTRANGE.
EM_GETTEXTRANGE allows the start character offset and end characters
offset to be used to specify the range of text to retrieve.  If the
start offset is in the middle of an end of paragraph run (i.e. \r\n),
then it should only retrieve the characters after the specified
character offset.
2009-01-27 11:21:16 +01:00
Dylan Smith c94e78a572 richedit: Handle case for EM_LINELENGTH when offset is between \r\n.
I found that ME_FindItemAtOffset and ME_CursorFromCharOfs are used
almost identically, except for how they handle a character offset that
is between a carriage return and line feed.  In this case
ME_CursorFromCharOfs sets the cursor's run offset to 0, but
ME_FindItemAtOffset instead returns the next run which is what was
causing ME_LINELENGTH to incorrectly return the length of the next
line.

Dylan Smith 0832737427 richedit: End of line sequence limited to 2 carriage returns.
riched32.dll does preserve the carriage returns and line feeds unlike
later versions of the richedit control, however the tests previously
missed the fact that a sequence of carriage returns followed by a line
feed (e.g. \r\r\r\n) can actually cause multiple paragraph breaks.

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 a6c7b6fdb2 richedit: Typing is ignored while mouse is captured.
I noticed a while ago that on Windows XP richedit controls ignored
characters typed while the mouse is captured (e.g. from holding the left
or middle button down).  Arrow keys, delete, and backspace, copying,
cutting, pasting, and everything else handled on WM_CHAR and WM_KEYDOWN
messages are also ignored.

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).

Michael Stefaniuc 273dbe4619 riched20: Fix a typo (stray address of operator). 2009-01-16 16:34:46 +01:00
Dylan Smith f73a34647f richedit: Respect the cbSize field on EM_GETPARAFORMAT.
EM_GETPARAFORMAT previously would overwrite the cbSize field with the
size of PARAFORMAT2, would read past the end of the struct, and might
indicate that PARAFORMAT2 fields are valid using the mask regardless
of the value of cbSize.
2009-01-16 12:57:10 +01:00
Dylan Smith 1181bb762f richedit: Prevent copying PARAFORMAT2 fields from PARAFORMAT struct.
If a EM_SETPARAFORMAT message is sent to the richedit control with bits
in the dwMask field that correspond to PARAFORMAT2 fields, then these
fields should be ignored.  Instead data was copied from outside of the
structure.

Dylan Smith 9a902f358b richedit: Added tests for initial options.
Using the WS_VSCROLL style causes the ES_AUTOVSCROLL option to be set,

set (except with richedit v1.0).

Dylan Smith b70b3e893f richedit: Added tests for zooming.
The contents of the text can be zoomed in with EM_SETZOOM, or with the
mouse wheel.  EM_SETZOOM is implemented, but these tests show bugs in
the implementation, and zooming using the mouse wheel isn't
implemented at all yet.

Dylan Smith f885d40d67 richedit: Store mouse captured state rather than calling GetCapture.
Windowless richedit control will not be able to call GetCapture without
a handle to the host window (and there is no ITextHost_TxGetCapture
method), but there is a ITextHost_TxSetCapture method available for
setting and releasing the capture on the mouse.  This means that the
richedit control will need to keep track of whether it has captured the
mouse or not to implement windowless richedit controls.

Dylan Smith 8089d980d1 richedit: Set bEmulateVersion10 initially to avoid retroactive changes.
Previously the WM_NCCREATE was handled by the as if it was always for
later versions, then the window proc for version 1.0 would make
appropriate changes afterwards.  Instead both versions should call the
same function (e.g. ME_MakeEditor) and provide the value for
bEmulateVersion10 to make the code clearer.

Dylan Smith 573102ee88 richedit: Fixed implementation of WM_GETDLGCODE message.
This fixes inconsistencies shown in the tests I added for the
WM_GETDLGCODE.  The tests covered different cases handled by the
current implementation in order to show that the native implementation
is simpler for all these cases.

Dylan Smith c636b59bcf richedit: Added tests for WM_GETDLGCODE message. 2009-01-08 13:34:53 +01:00
Dylan Smith 28645c64d5 richedit: Avoid rewrapping all text for isolated format changes.
When the character or paragraph format is changed the paragraph that
is changed is already marked to be rewrapped, so ME_MarkAllForWrapping
shouldn't be called.  Since ME_RewrapRepaint uses this function, it
shouldn't be called in these circumstances, since rewrapping all the
text can cause noticable delays when working with a lot of text.
2009-01-06 12:52:09 +01:00
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 c9977df853 richedit: Prevented a dereference of a freed pointer.
On WM_DESTROY the editor was getting freed, then it was used to obtain
a handle to the editor.  This patch moves it just before the editor is
freed within ME_DestroyEditor.

Dylan Smith 5dc1271ba6 richedit: Move message handling to function callable without window.
In order to make the message handling available to windowless richedit
controls, the message handling must be in a function that can be
called from the ITextServices_TxSendMessage method.  This method will
never have a handle to a window to pass to RichEditWndProc_common in
order to get the editor with GetWindowLongPtrW, but passing the editor
will work (even if hWnd is NULL).

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.

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.
2008-12-18 14:19:40 +01:00
Dylan Smith ced9bde4c0 richedit: Added tests for the formatting rectangle.

Dylan Smith 62db58545e richedit: Fixed ITextHostImpl return values for tests.
There were several methods that do not have a HRESULT for a return
value, so returning E_NOTIMPL is not appropriate. For all the BOOL
return values FALSE was returned to indicate the operation was not
performed.

Dylan Smith 4f41972b15 richedit: Move implementation of EM_GETTEXTRANGE to its own function.
The RichEditWndProc_common function is big enough already by handling
all the window messages, so moving code to handle a message to its own
function makes the code more readable.

Dylan Smith 7e94a230e1 richedit: Removed unused hwndEdit variable for the RTF parser.
There is no reason for the rich text format parser to need a handle to
the window, and even if there were it has a handle to the editor which
contains a handle to the window.  It is better to remove this
considering we need to cut down on the use of window handles to
implement windowless richedit controls.
2008-12-15 13:20:01 +01:00
Dylan Smith 8ab0570d02 richedit: Removed an unnecessary call to GetScrollInfo.
The vertical scrollbar state is stored internally within the control,
so should be used when possible.  This will become more necessary when
windowless richedit controls are implemented, and there will no hWnd
to pass to GetScrollInfo.
2008-12-15 13:16:20 +01:00
Dylan Smith 0c8e4b6d02 richedit: Compare editor rather than hWnd in ME_CalculateClickCount.
Comparing the editor as apposed to the handle to the window will work
just as well right now, but will also work when there is no window
handle to make a comparison with, which will be the case with
windowless richedit controls.

Dylan Smith 6901e0cec7 richedit: Use ME_EnsureVisible to implement EM_SCROLLCARET.
The code for the ME_EnsureVisible function does exactly what
EM_SCROLLCARET does, yet this code is duplicated in order to handle
this message.  It is simpler to just use the existing function to
implement the message, and avoid internally sending the EM_SCROLLCARET
when this function is available.

Dylan Smith 00fd6b62d3 richedit: Added test for correct behaviour for calling EditWordBreakProc.
EditWordBreakProc documented the third parameter as being the number

out that it should actually be the number of bytes in the string.

Dylan Smith 46d79b0363 richedit: Fixed EM_POSFROMCHAR for pos of text length.
For some reason EM_POSFROMCHAR was returning 0 when the position was

it should use the position at the end of the text for both these
cases.  The x value was also seen to be offset by 1 according to the
tests.
