r2214 | """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 | ||||
|
r2235 | 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. | ||||
|
r2248 | |||
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. | ||||
