Comment # 1 on bug 1137009 from Wolfgang Bauer

> Seems QtQuick.Layouts did change the version.

Sure, the version is changed with every new Qt version. QtQuick.Layouts 1.11 is
part of Qt 5.11.
I.e. diskmonitor 0.3.3 requires Qt 5.11, but Leap 15.1 comes with 5.9...

This requirement has been introduced in this bugfix:
https://github.com/papylhomme/diskmonitor/commit/901d73436e6878b68ceddceaaf94b8dfb6b4e8ae

I don't see why that should require 1.11 though.
The line probably was just copy/pasted from the Qt 5.11 docs I suppose.

So your "fix" should be fine. Actually even 1.0 should be ok I think.

Could you report this to the upstream developer at
https://github.com/papylhomme/diskmonitor/issues please?
