Hi,
The problem is that one day you will be changing your stack and not
doing anything with the GM and then suddenly *BANG* all your objects
will disappear off into the land of nod! They will still be in the
stack but their positions will be wild values like Top, Left =
25467,9456 and the only way to get the objects back inside the stacks
display area will be to delete all geometry on all objects and then
manually set their coordinates back inside the visible stack area
again. If you have a lot of objects this can take a *long* time and
is especially annoying if you have spent ages getting all the
positions "just-right".
Having being burnt like this a few times, I, along with most others
that have been using RunRev for a while don't go near the GM. It's
just not worth the risk.
If you *must* use GM you could at least protect yourself a bit by
adding some code like this to each object:
if the cpGMSaveRect of me = empty then
put the rect of me into the cpGMSaveRect of me
end if
Then run this once for each object once you have got all the
positioning right. At least then, if and when the GM goes Beswick you
can restore the original rectangle easily enough.
Just using GM and trusting it without question is like playing
Russian Roulette!
All the Best

Merci beaucoup Eric !
Well I found a way to combine the GM and scripting (I read your
tutorial...)
Well, I think the GM is good enough for minor use / basic things...
and scripting stays the best way...
Greets,
Christian

Bonjour Christian,

Hello,
I try since hours to do this :
I have an image (photo) on a stack which scales to the right and
down on resizing the stack (via Geometry Manager); I have a
graphic (rectangle) placed at a precise location on the image
(the user selects a portion of the image to hilite something on it);
Now I want that when the user resizes the window the graphic
scales and moves (up/down) proportionaly to the image , so that
the rectangle grows and shrinks with the image hiliting always
the same portion of the image (e.g. an eye of a face); I hope you
follow (it's difficult to explain this in English)...
I tried to use the GM in REv, but ...brrr... the graphic jumps
away from its original position when resizing...
So... please ! Heeeelp... This is getting me on my nerves ;-)
Thanks for any suggestions or solutions...

Actually don't trust the Geometry Manager and prefer to write your
own routines in a resizeStack handler ;-)
Here is, for instance, an excerpt from such a handler:
on resizeStack pNewW,pNewH,pOldW,pOldH -- note params passed by
Rev ;-)
global gPrefs
-----
if gPrefs["uAdds"] then ProportionalWResize the long name of img
"ToolbarShadow",pNewW,114
else ProportionalWResize the long name of img
"ToolbarShadow",pNewW,0
pass resizeStack
end resizeStack
And:
on ProportionalWResize pObj,pNewW,pDelta
local tRect
-----
put the rect of pObj into tRect
put pNewW - pDelta into item 3 of tRect
set the rect of pObj to tRect
end ProportionalWResize
Of course, the above example is simple and, sometimes, it might
appear more tricky...
But actually, Rev allows to script any complex resizing in any
case ;-)
Good luck!
Best regards from Paris,
Eric Chatonet.
