I can not make it smaller by SBASIC, using MDRAW command.

Thanks in advanced

Surely, the programmer who designed the menu already knows its
minimum
size? Or am I missing something?

I use the same routine as Tobias to read the values directly from the
working definition, eg after a resize call by the user. My point is
that it
seems pointless to calculate a value that is fixed and known in
advance: A
menu's minimum size is built into the menu presumably by the author
of the
program using it. I could only think of a few special cases, such as a
utility, like my MenView, to display menu (_men) files, and
programs for
designing menus, such as EasyMen itself. But perhaps thats what you
had in
mind. No, matter, Im glad you found a solution!

PS I sent this message last night - 9 hours ago - but it hasnt arrived
yet, so trying again 12.39 GMT+2. Why so slow? P
My aim is to resize the menu without moving .
Using the routines that I found on the EASYPTR manual (or on the web )
if I try to make it smaller over size its minimum , the menu shrinks
only up to its minimum size ( and is correct to do it ) and then moves
.
I have to overcome this drawback , the lower right corner should never
move, so I thought I calculate the new point of origin so
X current source - current width + minimum width
and
source current Y - current height + minimum height .
So i need to use the minimum size of the menu. I was hoping to get
poterve automatically .
I'm using Google translate , so probably I am sending you the nonsense
.. or the recipe of spaghetti with tomato sauce !

Well, then you need to PEEK the window definition [WD] rather than the
window working definition [WWD]. EasyPtr prepends its own header to
the WD. I think its always 28b long, in which case the
standard/minimum size can be found at
WD = APPA(<menu name>)
minx = PEEK_W(WD + 28): miny = PEEK_W(WD + 30)
This is not a universal formula, mind you, as more than one layout may
be defined (the menu designer will know). However, I'll leave that as
an excercise for now.. ;) Check out the excellent QPTR manual for
details, and use EasySource to dissemble your EasyMen menus.

This was not quite what Giorgio had in mind, as he doesnt use APPAn,
but the following construct (which I had forgotten about):
MDRAW#ch; 'my_menu'
ie MDRAW takes the menu name directly from an appended binary. The
solution then became:
ch = fopen('con')
rem Get the WD directly via the WWD
adr = mwdef(#ch): madr = peek_l(adr + 4)
xmin% = peek_w(madr): ymin% = peek_w(madr + 2)
..
mdraw#ch; 'my_menu',..
Arguments and provisos as previously noted.
