Subject: Don't use Q_EMIT, it's not needed anymore
X-Git-Tag: pulseview-0.4.0~45
X-Git-Url: https://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=25e734c848a23fc526d5b410235e8e7e9fb5edde

Don't use Q_EMIT, it's not needed anymore

The Q_EMIT macro (just like the regular Qt emit) is syntactic
sugar to let people who read the code know that a method call
placed somewhere is actually a signal.

We don't use Q_EMIT consistently throughout PV and I don't
think it's really needed anyway, so this patch removes the
few remaining instances.
