140 <h2>wxProcess</h2>
141
142 wxProcess lets you get notified when an asyncronous child process
143 started by wxExecute terminates, and also to get input/output streams
144 for the child process's stdout, stderr and stdin.
145
146 <p>
147 This demo launches a simple python script that echos back on stdout
148 lines that it reads from stdin. You can send text to the echo
149 process' stdin by typing in the lower textctrl and clicking Send.
150
151 <p>
152 Clicking the Close Stream button will close the demo's end of the
153 stdin pipe to the child process. In our case that will cause the
154 child process to exit its main loop.
