Connections

Here you can learn how to connect and disconnect objects in pdpy. The code we’ll execute is here:

import pdpy_lib as pdpy
pd = pdpy.PdPy(name='test_disconnect',root=True)
obj = pdpy.Obj('loadbang')
printer = pdpy.Obj('print')
pd.create(obj, printer)
pd.connect(obj,printer)
pd.__arrange__(pd)
print(pd.__pd__())
pd.disconnect(obj,printer)
print(pd.__pd__())

First, we import pdpy_lib as pdpy and create a PdPy instance:

>>> import pdpy_lib as pdpy
>>> pd = pdpy.PdPy(name='test_disconnect',root=True)
Found  darwin  platform.
Locating pd...
Found pd at:  /Applications/Pd-0.52-2.app/Contents/Resources/bin/pd

Then, we create a loadbang and a printer, to test:

>>> obj = pdpy.Obj('loadbang')
>>> printer = pdpy.Obj('print')
>>> pd.create(obj, printer)
<pdpy.PdPy object at 0x106596820>

We connect them, and let’s arrange them so that we can print them:

>>> pd.connect(obj,printer)
>>> pd.__arrange__(pd)
Initialized Arranger graph placing algorithm.
>>> print(pd.__pd__())
#N canvas 0 22 450 300 12;
#X obj 10 10 loadbang;
#X obj 10 58 print;
#X connect 0 0 1 0;

Now, try disconnecting them:

>>> pd.disconnect(obj,printer)
Disconnected 0

Let’s see the result:

>>> print(pd.__pd__())
#N canvas 0 22 450 300 12;
#X obj 10 10 loadbang;
#X obj 10 58 print;
