I'm having problems building using ming. I get the following error:

If I comment out the line, it builds ok.

Hi,

I've just spent the morning converting and documenting Rammy's perl toolb=
ar
functions into XS. They're now in the CVS.

The new functions are as follows:
# (@)METHOD:SetButtonState(BUTTON, STATE)
# (@)METHOD:SetStyle(STYLE)
# (@)METHOD:SetExtendedStyle(STYLE)
# (@)METHOD:GetStyle(STYLE)
# (@)METHOD:MoveButton(BUTTON, TARGET)
# (@)METHOD:SetImageList(IMAGELIST)
# (@)METHOD:SetHotImageList(IMAGELIST)
# (@)METHOD:SetDisabledImageList(IMAGELIST)
# (@)METHOD:GetImageList()
# (@)METHOD:GetHotImageList()
# (@)METHOD:GetDisabledImageList()
# (@)METHOD:ChangeBitmap(BUTTON, BITMAP)
# (@)METHOD:CheckButton(BUTTON, CHECKED)
# (@)METHOD:DeleteButton(BUTTON)
# (@)METHOD:SetToolTips(TOOLTIP)

SetToolTips is not really needed, as you should be able to assign a toolt=
ip
object using the -tooltip option when constructing the toolbar now. Same
thing with SetImageList; you should be able to use -imagelist to set an
imagelist now.

Note that there is already a Padding() method for the toolbar so I didnt =
add
Rammy's padding one which seemed to do a similar thing. I've also
(hopefully) fixed the "tooltips crash application on exit" bug that appea=
red
when I ran Rammy's test code.

There is some safety checking on SetImageList, AddBitmap and ChangeBitmap=
.
You cannot call SetImageList and AddBitmap/ChangeBitmap on the same toolb=
ar
as microsoft says this would be a really bad idea, so you get a croak abo=
ut
it if you try it.

Another thing is, I've modified the ButtonClick event so that when a butt=
on
that has the TBSTYLE_DROPDOWN style applied to it is clicked, an extra
argument gets passed to ButtonClick with the value of 1. This allows you =
to
tell if you need to show a drop-down menu.

There have been a ton of constants added to GUI.pm and GUI_Constants.cpp,=
 so
you can use most of the regular toolbar styles, extended styles, button
styles etc. One word of warning is to avoid using the BTNS_*** constants =
and
use the TBSTYLE_*** equivalents instead, as the availability of the BTNS_=
***
constants depends on the headers and compiler used (they're a new thing).

I added dwFlags to the USERDATA and CREATESTRUCT structs. This dword is
intended to store any per-object flags needed. for instance, the toolbar
uses FLAGS_TB_HASBITMAPS to remember if AddBitmap has been called and
complain if the user attempts to SetImageList on the same toolbar object.
Developers: add flags as you see fit.

One last thing. We're running out of mask bits in the NEM. Are they reall=
y
needed? The mask only appears to be used as a speed thing (to avoid doing=
 a
hash lookup for each event) so perhaps it would be more sensible to group
some events together or something? Thoughts please...

Steve
