在 IPython qtconsole 中确定终端宽度

Question

运行 IPyhton qtconsole 时，如何确定列数以最大化文本显示，使其在当前设置中看起来不错？

Answer 1

Try to change the width and height in ipython_qtconsole_config.py

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

Answer 2

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()
