ResetCrosshairEvent(Bool skipRefresh=False): False(), skipRefresh_(skipRefresh)

virtual const Bool skipRefresh() const

Description

Synopsis

ResetCrosshairEvent is created and sent to MWCCrosshairTool (via WorldCanvas::handleEvent()) to tell the crosshair to reset itself.

Motivation

This allows display library objects (e.g. MSAsRaster) to remove the crosshair from the screen when appropriate (e.g. when it has received a selection event from it).

Member Description

ResetCrosshairEvent(Bool skipRefresh=False): False(), skipRefresh_(skipRefresh)

caller sets skipRefresh=True iff it is handling refresh itself.
