"""A Simple wx example to test IPython's event loop integration.
|
|
|
|
|
|
To run this do:
|
|
|
|
|
|
In [5]: %gui wx
|
|
|
|
|
|
In [6]: %run gui-wx.py
|
|
|
|
|
|
Ref: Modified from wxPython source code wxPython/samples/simple/simple.py
|
|
|
|
|
|
This example can only be run once in a given IPython session because when
|
|
|
the frame is closed, wx goes through its shutdown sequence, killing further
|
|
|
attempts. I am sure someone who knows wx can fix this issue.
|
|
|
|
|
|
Furthermore, once this example is run, the Wx event loop is mostly dead, so
|
|
|
even other new uses of Wx may not work correctly. If you know how to better
|
|
|
handle this, please contact the ipython developers and let us know.
|
|
|
|
|
|
Note however that we will work with the Matplotlib and Enthought developers so
|
|
|
that the main interactive uses of Wx we are aware of, namely these tools, will
|
|
|
continue to work well with IPython interactively.
