Purr Data 2.4.2 is out:
Please report bugs here:
* fixed freeze when flooding the Pd window with messages
Updating the scrollbars turns out to be expensive. It
was possible to print messages from Pd to the GUI fast
enough that Purr Data's GUI would spend all its time
redrawing the scrollbar position. Purr Data now throttles
the scrollbar update in the Pd Window to avoid this problem.
(We could also further improve it by throttling and/or
batching the addition of new text nodes in the printout
area, but that doesn't seem necessary so far.)
There was also a report of an open text window for
[text define] causing a freeze when populating it with
10,000 lines. But this turns out to be a problem with
the Pd<->GUI interface of [text define]-- for each line
you add it will a) clear the window and b) resend every
line of the binbuf to the GUI.
* fixed array tick labels
Array tick labels were displayed at a slightly different
size and weren't centered on the tick lines. Thanks to Albert
for reporting and helping fix it.
* normalize array trace line thickness so it is always visible
Thanks to Albert for reporting and fixing.
* send correct pointer for data structure array element event callbacks
If you set up an event like
[loadbang]---[drag 1(---[draw rect 40 40]
you now get the correct pointer to the outlet, even for
array elements. This makes the event callback functionality
much more expressive.
* only redraw affected data structure array element when updating a field for [draw array]
The [draw array] object is still a work-in-progress. But this will
be a substantial speedup in redrawing array elements.
For example, suppose you want to change the color of the 59th
rectangle in a data structure array of 1000 elements. With [plot],
when you update the field associated with that color the entire
scalar is erased and redrawn: 1000 x size of the message to
erase and draw a rectangle.
With [draw array], this is reduced to: size of message to update
a single rectangle's visual attributes.
