Determining terminal width in IPython qtconsole

Question

When running IPyhton qtconsole, how can the number of columns be determined for maximizing text display so that it looks good in the current setting ?

It can't. We know that's not ideal for some situations, but it's part of a general principle that code shouldn't know too much about what may currently be displaying its output. — Thomas K, Jan 09 '15 at 01:06
it looks like the code is out there in the qtconsole (ConsoleWidget.sizeHint()), but I can't figure out how to get to that from the script running underneath the qtconsole — KevinP, Jan 11 '15 at 04:23

Try to change the width and height in ipython_qtconsole_config.py

# c.IPythonWidget.width = 81
# c.IPythonWidget.height = 25

sizeHint() didn't work well for me (didn't resize with the window), but size() worked fine.

In [10]: ipyida.ida_plugin.obj.widget.parent.size()
Out[10]: PyQt5.QtCore.QSize(1241, 894)

To get access to the running instance, I had to patch the .py file that imported qtconsole and insert this:

globals()['obj'] = self

In my case, the qtconsole is launched from IDA, so I can then access via:

instance be accessed via:   
    import ipyida           
    ipyida.ida_plugin.obj.*

To calculate the number of character columns, you will have do something like this:

f = ipyida.ida_plugin.obj.widget.parent.fontInfo()
f.pixelSize() # 11
w = ipyida.ida_plugin.obj.widget.parent.size().width() // f.pixelSize()
