[jazzplusplus-devel] Selection

[Dave F. <dav...@co...>]

All,

Ok, now I'm pretty thoroughly confused, again.  :(  I'm working on making 
selection and the clipboard exist inside jppProject instead of inside the 
GUI.  Here's what I've got:

With an empty project, I can select events.  There aren't any to select.  When 
I load a midi file, selection doesn't work anymore at all.  (I may have 
broken that, sorry!)

I'm thoroughly confused for several reasons.  First, I'm not very good at 
graphics/GUI stuff when I have to build my own, so I use stock widgets pretty 
much all the time.  :)  So I don't understand the drawing code all that well, 
well, not at all, really.  Second, the selection code is extremely 
convoluted.  I've narrowed it down, I think.

It looks like when you're done selecting, jazz uses a Filter object to store 
the selection.  I feel like Marty McFly, but what the hell's a Filter?  ;)  
So when you do have a selection with real events in it, do the events get 
copied to the filter object, or does the filter object just store locations 
of those events?

Dave
