console: IPython console widgets

This module provides an IPython console widget.

You can push variables - any python object - to the console’s interactive namespace. This provides users with an advanced way of interacting with your program. For instance, if your program has a PlotWidget or a PlotWindow, you can push a reference to these widgets to allow your users to add curves, save data to files… by using the widgets’ methods from the console.

Note

This module has a dependency on qtconsole. An ImportError will be raised if it is imported while the dependencies are not satisfied.

Basic usage example:

from silx.gui import qt
from silx.gui.console import IPythonWidget

app = qt.QApplication([])

hello_button = qt.QPushButton("Hello World!", None)
hello_button.show()

console = IPythonWidget()
console.show()
console.pushVariables({"the_button": hello_button})

app.exec_()

This program will display a console widget and a push button in two separate windows. You will be able to interact with the button from the console, for example change its text:

>>> the_button.setText("Spam spam")

An IPython interactive console is a powerful tool that enables you to work with data and plot it. See this tutorial for more information on some of the rich features of IPython.
