Opening the matchbox keyboard from tkinter GUI

[krisss]

I'm using a touch screen and I'd like to open the matchbox keyboard when an entry box is tapped in my GUI. Something like below:

Code: Select all

freq_entry = Entry(root, textvariable=entrytext)
freq_entry.bind("<1>", numpad_open)

where the function numpad_open opens the keyboard. So what would numpad_open look like? I'm not sure how to open a program with python or even what the matchbox keyboard executable is called.
