Doubt in hierarchy selection

[noreply]

Hi all,
I have called a big layout as an instance in an different cellview.
And i require to draw/place the labels on the top level hierarchy(The
label has to be placed exactly at the same location in the above
hierarchy).
From the previous posts in our forum i got a good amount of idea. And
i have used andrew's code for drawing the label:
/********************ANDREWS CODE**********************/
procedure(RLcopyHier()
xform=list(0:0 "R0" 1)
; reverse the list to get the transform the right way around
/*Rem for the higetcuurentwindow() to work you should have descended
into the layout instance first*/
foreach(instPath reverse(geGetInstHierPath(hiGetCurrentWindow()))
xform=dbConcatTransform(xform car(instPath)~>transform)
)

; now copy selected shapes to the top cellView, with the right
transformation
topCv=geGetTopLevelCellView()
newShapes=foreach(mapcar shape geGetSelSet()
dbCopyFig(shape topCv xform)
)
);procedure
/
************************************************************************/
The Above code served its purpose well if we select any object and
execute the procedure.
Since I wanted lot of labels to be drawn, My idea was to descend down
the hierarchy and select all the object and then obtain only the
database id's of the label and then run the above procedure using
foreach() loop:

geSelectAll()
RLlabelList=nil
RLinstList=geGetSelSet()
foreach(instName RLinstList
RLlabelTemp=instName~>objType
if(RLlabelTemp == "label";to select only the labels
RLlabelList=cons(instName RLlabelList)
);if
);foreach
length(RLlabelList)
geDeselectAll()
for(i 0 length(RLlabelList)
instName=nth(i RLlabelList)
geSelectFig(instName)
RLcopyHier()
);for


unfortunately the above code is not running , The error i obtained is
as follows:

*Error* geSelectFig: argument #1 should be a database object (type
template = "d") - nil

I dont get exactly what the problem is.
Could anyone please help me out.
Regards,
Lokesh.

Two main problems - your use of variable names makes the code rather hard to
read.... and secondly the for() loop at the end is a very inefficient way of
doing a foreach loop.

Also, it seems overkill to select everything just to find the shapes which are
labels.

The main issue is that you're using nth() in the second loop (which is the
inefficient bit) and because you're setting i from 0 to the length of the list,
the very last value of i will result in nth(i RLlabelList) dropping off the end
of the list - because 0 is the first, length-1 is the last.

Much simpler would be to do:

cv=geGetEditCellView()
RLlabelList=setof(shape cv~>shapes shape~>objType=="label")
geDeselectAll()
foreach(label RLlabelList
geSelectFig(label)
)
RLcopyHier()

In fact I would probabably alter RLcopyHier to allow you to pass a list of
objects instead of the selected set:

procedure(RLcopyHier(@optional (figures geGetSelSet()))
let((xform topCv newShapes)
xform=list(0:0 "R0" 1)
; reverse the list to get the transform the right way around
; Rem for the geGetInstHierPath to work you should have descended
; into the layout instance first
foreach(instPath reverse(geGetInstHierPath(hiGetCurrentWindow()))
xform=dbConcatTransform(xform car(instPath)~>transform)
)
; now copy selected shapes to the top cellView, with the right
; transformation
topCv=geGetTopLevelCellView()
newShapes=foreach(mapcar shape figures
dbCopyFig(shape topCv xform)
)
);procedure


And then you can just do:

cv=geGetEditCellView()
RLlabelList=setof(shape cv~>shapes shape~>objType=="label")
RLcopyHier(RLlabelList)

If RLcopyHier() is called with no arguments, it works on the selected set.

Note, I didn't test this code...

Andrew.
