Thanks Miklos for your feedback.
I found the code for Draw both in SdrObject::ImpDragCalcRect [1] and
SdrTextObj::ImpDragCalcRect [2]
But it is not used for charts. I noticed that the rules to make
proportional with or without Shift are different between drawing objets
and charts :
- for Drawing objects: default is not proportional
- for Chart and Pictures: default is proportional for corners handles
and not proportional for edge handles
Does anyone has some code pointers for resizing a picture or a chart?
Best regards
Laurent

I'm working on bug 163816 [1] to preserve ratio Width/Height of an OLE
object (such as a chart in Calc) when Shift is pressed. Work under progress
is here [2].
I suppose that such behavior is already coded somewhere in LibO (for
instance when resizing an object in Draw). Can someone provide some
interesting code pointers?
I believe SdrSnapView::SetOrtho() is related, also Writer's
SwWrtShell::Drag() is related, this is called "proportional" resizing.
See the code at

hopefully some of that is also relevant for Calc.
