[PATCH] windres: (1) default dialog styles

[Gunnar Degnbol <degnbol at danbbs dot dk>]

windres adds WS_POPUP | WS_SYSMENU | WS_BORDER to all
dialogs. MS rc.exe sets these styles only if no STYLE
statement is present.

This is a problem because dialogs used as controls in other
dialogs (e.g. open/save dialog extensions) should not have
the WS_POPUP style. It can be worked around by adding the
style NOT WS_POPUP.

The patch initializes style to 0 when initializing dialog,
instead of setting it to dialog.style when the STYLE
statement is parsed. It is still assigned to dialog.style
when a STYLE statement is present. If a FONT statement is
present it sets the DS_SETFONT style of both style and
dialog.style, so it is independent of the order.

Incomplete fixes for this was posted by Bernd Herd:
http://sources.redhat.com/ml/binutils/2002-02/msg00021.html
and Eric Kohl:
http://sources.redhat.com/ml/binutils/2002-01/msg00130.html
They were combined with fixes for other bugs.

I will post 4 simple fixes from Bernd's patch, one at a time,
and also fixes for the 7 other bugs I found while
investigating this one. I will look some more at Bernd's last
fix (for CONTROL initialization parameters) and at Eric's
other fix (for the FONT statement).

There are no dependencies between these patches.

ChangeLog:

2002-03-19 Gunnar Degnbol <degnbol@danbbs.dk>

	* rcparse.y: Don't add default dialog style when
	explicit style specified

defstyle.rc:

101 DIALOG 0, 0, 186, 95
STYLE 0
BEGIN
     DEFPUSHBUTTON "OK",1,129,7,50,14
END

before patch (I have removed the generated comments):

$ /bin/windres.exe -i defstyle.rc
LANGUAGE 0, 0

101 DIALOG MOVEABLE DISCARDABLE 0, 0, 186, 95
STYLE 0x80880000
BEGIN
   DEFPUSHBUTTON "OK", 1, 129, 7, 50, 14, 0x50010001
END

After patch:

$ /usr/local/bin/windres -i defstyle.rc
LANGUAGE 0, 0

101 DIALOG MOVEABLE DISCARDABLE 0, 0, 186, 95
BEGIN
   DEFPUSHBUTTON "OK", 1, 129, 7, 50, 14, 0x50010001
END
