Re: [Denemo-devel] A major re-structuring.

I tried to get the Restructure branch to try it out, but it appears that all 
the download links (including Sourcecode) are broken. I'm getting a 404 on 
every platform.

Subject: [Denemo-devel] A major re-structuring.

One of the most fundamental mistakes made when Denemo was first started was not 
to have a structure for a Denemo measure. Instead it is just a list of the 
objects in the measure. As a knock on effect, nothing can be stored with the 
measure that applies to the whole measure.
This has made it difficult to fix the way that information about the context 
(clef, timesignature ...) of an object is stored, especially when a measure has 
no objects. It has long been my ambition to get rid of the way the calculation 
of the context information is computed - a draw time. This is still causing 
failures in Check Score on occasions.

As a start I have created a branch Restructure in which a staff now has a list 
of Measure structures, which for now just has one element, viz.
the list of objects.

I've done a first trawl of all the code to try and make the change work 
properly, and I've tested (with the default build) loading files, starting new 
files, adding and deleting movements, staffs, measures, notes, chords, copy and 
paste creating snippets, pasting and following them Undo and Redo.

It would not surprise me if I have missed something, it is perilous work. The 
symptoms of an error are crashes, often with memory allocation warnings. But, 
so far it seems good. If anyone can help testing this version that would be 
good!

Richard
