Subject: Standardize on 'event' as name for all Qt events.
X-Git-Tag: pulseview-0.4.0~336
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=d9ea96280ab1128427143660ae375c30b19aa0cb;p=pulseview.git

Standardize on 'event' as name for all Qt events.

Use 'event' consistently across the whole code-base as variable name
for Qt events (previously 'e' or 'evt' was also used).
