Bounding Box of a Group

Recommended Posts

Is there a way to get the bounding box (x1,y1,x2,y2) of a group.  I want to create a group and then get its bounding box.  Selecting the objects and then grouping them does not yield a handle to the group

SelectObj(((Criteria)));        

Group;

GrpObj := LNewObj:

{GrpObj returns nil here}

 

I would like to get a handle to the group and then get its bounding box, but that doesn't seem to work.

It seems to work here.

 

Procedure GroupBB;

Var	X1,Y1,X2,Y2:Real;

Begin
	GetBBox(FSActLayer,X1,Y1,X2,Y2);
	AlrtDialog(Concat(GetTypeN(FSActLayer),' - ',X1,' - ',Y1,' - ',X2,' - ',Y2));
End;

Run(GroupBB);

Probable that Group does not change LNewObject.  Try the Waldo Method.

 

 

Insert Locus, LNewObj,GetPrev(LNewObject), Delete Locus.

 

I think this was originally disclosed by @Gerard Jonker back around 2002.

Sam,

   A new Group is always created on top of the stacking order, so if you are on a design or sheet layer, LActLayer will return a handle to a new Group. If you are drawing inside a container, you can use the Waldo method that Pat mentioned. With the handle you can then get the Group's BBox.
