I can not make it smaller by SBASIC, using MDRAW command.
Now, is there any way to read this minimum size of the menu? The manual

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!

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.
