Selections

The following !set keywords affect object/cell selections using the pointing device.

MarkInstanceOrigin
Value: boolean.
This variable applies in physical mode only. When set, selected instances will have the cell origin marked with a cross. This may seem trivial, but marking the origin requires a bit of overhead since it requires running a transformation and keeping track of an additional redisplay area since the origin may be outside of the cell bounding box. Thus, the default is to not show the mark.

This variable tracks the state of the Show origin of selected physical instances check box in the Window Attributes panel from the Set Attributes button in the Attributes Menu.

SelectTime
Value: integer 100-1000.
When button1 is used for object manipulation and editing, there is a time delay which differentiates a ``click'' from a ``drag''. This delay, which defaults to 250 milliseconds, can be adjusted by setting this variable. If the user encounters difficulty establishing an area select, for example, as opposed to a move/copy operation, then setting a longer time delay may be advantageous.

NoAltSelection
Value: boolean.
When set, the legacy logic is used for mouse click selection operations.

MaxBlinkingObjects
Value: integer 500-250000.
This can be set to an unsigned integer in the range 500-250000. If there are more than this number of objects selected, they won't blink in true-color display modes. If NoPixmapStore is set, this threshold is divided by 8. The default if not set is 25000 objects. If there are too many objects, the time to redraw for blinking becomes excessive, this variable can be used to fine-tune this threshold to the user's graphical system.
