This fix ensures that packages satisfying dependencies
for other packages come before these in the flat package order.
This is in particular important for macro packages where those
supplying libraries need to be executed before the ones
that use these.
First steps towards installer support. Specifically:
- basic installation methods, basic framework
- file utilities for directory copy
Side effect: temp directories of unit tests are
now cleared prior to test run.
Side effect: the log dialog now has an icon
indicating whether there are errors or warnings.
A new utility widget has been introduced to
attach log messages (warnings/errors) to
dialogs. This widget is a QToolButton that
is invisible initially. It provides warning
and errors channels and can be fed messages.
If errors or warnings are fed, the tool button
becomes visible. If (directly) embedded inside
a QFrame, the frame's background will turn
red to indicate the region of interest.
The button can be pushed to read the log.
The button is called lay::AlertLogButton
and is found in layLogViewerDialog.h.
TODO: move to layBasic.
