Subject: Scan: Don't enable "OK" button if no device is found.
X-Git-Url: http://git.code-monkey.de/?p=pulseview.git;a=commitdiff_plain;h=f44133787621a589cfd65b8726a2433df01e2c6c

Scan: Don't enable "OK" button if no device is found.

Even when no devices were found after "Scan for Devices", a user could
click on the active "OK" button. This fixes the behaviour so that the
"OK" button only gets enabled when a device has actually been found.

This fixes bug #237.
