Subject: Decorate all functions used as slots.
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=f517686f9b9dd004876be97ad6376021163d4120;p=sigrok-meter.git

Decorate all functions used as slots.

In addition to small memory/speed benefits, this makes the intention to use
them as slots more clear.
