Description
The Process class is used to start external programs and to communicate with them. !WARNING AT LAST YOU HAVE TO CLOSE THE PROCESS!
Functions
`$addArgument(<process-name:string>)`
With this command you give the process name (or more arguments) for comunication. Es: see the next example.
`$startProcess()`
Tries to run the process. Es: %process=$new(process); %process->$addArg("cmd.exe"); %process->$start();
`<string> $readStdout()`
Reads the data that the process has written to standard output.
`<string> $readStderr()`
Reads the data that the process has written to standard error. Es: -------------------Start: class (test,object) { slotReadStdout() { %stdo = %Process->$readStdout() #%Aoutput->$append(%stdo);// coming soon in the new texteditor class %Aoutput->$settext(%stdo); } slotReadStderr() { %stderr= %Process->$readStderr() #%Aoutput->$append(%stderr);// coming soon in the new texteditor class %Aoutput->$settext(%stderr); } } %tt=$new(test) %A=$new(widget) %A->$setGeometry(100,100,400,300) %layoutA=$new(layout,%A) %Ainput=$new(lineedit,%A) #%Aoutput=$new(textedit,%A)// coming soon in the new texteditor class %Aoutput=$new(label,%A) %bclosekill=$new(button,%A) %bclosekill->$settext("&CloseKill ") %bkill=$new(button,%A) %bkill->$settext("&Kill ") %bterminate=$new(button,%A) %bterminate->$settext("&Ask to Terminate ") %layoutA->$addwidget(%Ainput,0,0) %layoutA->$addwidget(%Aoutput,1,0) %layoutA->$addwidget(%bclosekill,3,0) %layoutA->$addwidget(%bkill,4,0,) %layoutA->$addwidget(%bterminate,5,0) %Process=$new(process) %Process->$addArgument("cmd.exe") %Process->$startProcess(); connect %Process readyReadStdout %tt slotReadStdout connect %Process readyReadStderr %tt slotReadStderr privateimpl(%Ainput,returnPressedEvent) { %command=%Ainput->$text() "\r\n" %Process->$writeToStdin(%command); %Ainput->$setText(""); } privateimpl(%bclosekill,mousepressevent) { %Process->$closekill(); delete %A; } privateimpl(%bkill,mousepressevent) { %Process->$kill(); delete %A; } privateimpl(%bterminate,mousepressevent) { %Process->$tryTerminate(); delete %A; } %A->$show(); --------------------End.
`$writeToStdin(<command:string>)`
Whit this command you send a command to the process:
`$closekill()`
This tries to terminate the process the nice way. If the process is still running after 5 seconds, it terminates the process the hard way. (I think that this is the better way.) Es: %Process->close_kill();
`$kill()`
Kill the process in hard way.(Bad Idea)
`$tryTerminate()`
Tries to terminate the process.(It could be well but...)
`$closeStdin()`
Close the standard Input.
`<boolean> $isRunning()`
Return 1 if the process is running, else return 0.
`<boolean> $normalExit()`
Returns TRUE if the process has exited normally; otherwise returns FALSE.
`$readyReadStdoutEvent()`
This function is invoched by the process when there are new datas. The default implementation emits the $readyReadStdout() signal.
`$readyReadStderrEvent()`
This function is invoched by the process when there are new error messages. The default implementation emits the $readyReadStderr() signal.
Signals
`$readyReadStdout()`
This signal is emitted by the default implementation of $readyReadStdoutEvent(). If you reimplement that function you will have to emit the signal manually (if you still need it).
`$readyReadStderr()`
This signal is emitted by the default implementation of $readyReadStderrEvent().
