how to select and deselect a layer using only one bind key?

 Hi Prabhakar,

I will guess that you are talking about selecting shapes on a specific layer-purpose pair since you also mentioned deselection.

There are probably a few different approaches that you could take (for selection):

• Iterate over the shapes in the cellview that match and select them
• Iterate over the shapes in the cellview and select those that match
• Select everything and deselect things that do not match

I would think that the first method is probably the most efficient way out of those I mentioned.  To keep it simple, you could use the current LSW layer as the way of specifying which layer you want to select shapes on. An alternative might be to look at which shape the mouse is over and use the layer of that shape.  So the bindkey for selection could be as simple as the following:

In other words, "select all of the shapes that are in the set of shapes in the cellview such that the shape has the same layer-purpose pair as the current entry layer in the LSW".  Assign it to a bindkey, for example:

Now, for deselection, do you want to deselect everything (e.g. the <Ctrl>-D bindkey), or everything on that layer only?  If you want the latter, and you want a single bindkey to do the work, then it probably would be a good idea to put the code in a procedure.  This procedure could test if any of the shapes on the layer are already selected, and if so, deslect the shapes on the layer, otherwise, select the shapes on the layer (as in the above example). So you might do something like the following:

procedure(CCStoggleLayerSel()
  let( (cv shapes)
    cv = geGetEditCellView()
    shapes = setof(shape cv~>shapes shape~>lpp==leGetEntryLayer())
    ;; if at least one shape is even partially selected, then deselect all 
    ;; the shapes on that layer, otherwise select all the shapes on that layer
    if( exists(shape shapes geIsFigSelected(shape))
      mapc('geDeselectFig shapes)
      geSelectFigs(shapes)
    ); if
  ); let
); procedure CCStoggleLayerSel

I hope that this is the sort of thing that you were looking for.
