about grread deselect objects

[masao_8]

Is it possible to use the grread function to deselect objects by holding down the SHIFT key+left click?

I think you would need to test for 'shift' being pressed and the test for a left mouse entity selection.

 

Do a 'princ' on your grread loop to display what you are doing, shift and select something - which should give you what you want to test for.

Isn't that how CAD works already? you select something either by mouse clicke or window it will be highlighted hold shift to deselect it the same way.

I know if you have to many things selected they are no longer highlighted.

Doesn't that depend on PICKADD value? I do believe the default is select to add and shift select to deselect from selection set.

 

To that end, it needs to be clarified from OP what they need, my WAG is something being already done with grread and need to deselect.

 

AFAIK (and that's very little, mostly from my previous thread )

 

 

The left click is doable with grread, but it would ignore the SHIFT (also CTRL, etc.), so probably would need something else to show the SHIFT key is pressed.

 

Which reminds me I need to get back to work on that and the centerline on rivers, roads, etc. problem when I get regular work caught up.

Perhaps you could use the undocumented (acet-sys-shift-down) express tools function within the grread loop? Then you would have to manipulate highlighting with (redraw [3/4]) and use (ssadd) and (ssdel) to update the selection set.
