That's a tricky one. I think that <<Loaded>> should be
sent
when the patch is all done, so the current situation is a bug.
Ah, ok.
Since the drawing commands come from 'pd', 'pd' would have to
trigger the
<<Loaded>> event. I forget how its triggered now.
It's triggered in the last line of ::pdtk_canvas::finished_loading_file
in
pdtk_canvas.tcl. That proc is called by ::pd_bindings::map in pd_bindings.tcl, where it is preceded by: pdsend "$mytoplevel map 1"
Maybe that line above needs to be the last line of the proc, and when pd is done mapping it should make a call to
::pdtk_canvas::finished_loading_file?
I'm still not solid on the back and forth between gui and pd, so
I'm not sure
if that would help or not.
It'll need to be somewhere else entirely, I think. "map" is the concept of the window being mapped to the screen. As you seem to have discovered, the window is mapped to the screen, then pd sends all its draw commands to it. So ::pdtk_canvas::finished_loading_file should be called once Pd is done sending draw commands.
Right-- that's why I was thinking it should go on the pd side in canvas_map, after the last sys_vgui call.
The Pd side of map will probably give you more or less the same place. "map" just means the window is active, I don't think it means that Pd is done drawing. I think there needs to be a way to find when Pd has stopped parsing the .pd file and sending Tcl draw commands.
