Subject: Save dialog: Fix cancellation
X-Git-Url: http://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=cd38c84cb223ba9ecb01d9b0fc0ac11cd9e1d7a1

Save dialog: Fix cancellation

Without the fix cancellation of save data does not work

How to reproduce:
	1. Start PV with demo device and generate sufficient data, e.g. demo device 1GSa/s, 10MSa
	2. Save data (should take at least 30s) and try to cancel saving
	3. PV continues saving data and dialog reappears after next progress update
