Subject: Fix #1107 by implementing a copy-to-clipboard menu entry
X-Git-Url: http://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=c764c995115fbcd3668a02ce1ce0950b5fb6c670

Fix #1107 by implementing a copy-to-clipboard menu entry

In the process, it turned out that the sample range for
cursor position-based menu commands was wrong: it didn't
take the width of the viewport header into account. This
is now fixed as well.
