[PiTiVi] Update for week of July 08, 2007

[Brandon Lewis <brandon_lewis berkeley edu>]

Refreshing everyone's memory, PiTiVi is a non-linear video editor 
written using GStreamer and Pygtk.

I went camping last week, so didn't send an update. I did get a bit of 
work done. Earlier this year, I had written a widget for displaying 
Pixbufs at a constant aspect ratio, but the code was buggy. I spent a 
few hours last week fixing that. Then I tracked down the source of a bug 
 that prevented the widgets from updating when their pixbufs were changed.

Previously, the SimpleSourceWidgets -- the widgets that represent each 
clip in the movie timeline, had been a bit over-sized. So I spent the 
weekend doing little cosmetic tweaks to get them down to size. I also 
fixed it so that the label which holds each clip's filename is 
ellipsized, rather than simply cut off. I also found that by changing 
the packing options slightly, I could get the bottom half of the window 
not to expand with the widget. This improves the way the widget scales, 
causing more space to be given to the thumbnail image.

On sunday I finally got around to refactoring the code behind the 
editing slider into a new class. While I was at it, I added a "trimming 
bar" above the editing slider to indicate where the start and stop 
points are on the clip. Meanwhile, Edward Hervey finally managed to 
eliminate a crasher bug that had been driving me crazy while testing.

Today, I've been following up on the slider code by making the arrow 
buttons which adjust the start and stop points work. That pretty much 
completes the basic functionality of the widget. However, Edward and I 
have been talking about adding a "cancel" button, and a button to split 
the clip being edited into two smaller clips. That is probably what I 
will be working on the coming weeks.

Hope to see you all at GUADEC!
