I've been wondering about this myself in the context of http://ytd-meego.googlecode.com . Rather than linking in all sorts of specialized tightly threaded media-handling code, some apps might work best by invoking and controlling single-purpose specialized command-line progs that execute as a subprocess, e.g. for capturing, encoding, playing back of media. Seems like QtQuick/QML ought to have a "declarative subprocess" facility as well. (Or maybe it does and i didn't see it documented anywhere?) This would allow launching of subprocesses asynchronously, using "declarative" statements to handle changing application state based on the subprocess. Subprocess state changes are expressed via high-level messages such as: BeforeProcessExit AfterProcessExit, OnOutputLine, OnOutputJSON, OnOutputRegexp, etc. In Unix, such functionality has long been provided by http://en.wikipedia.org/wiki/Expect . I think it would be very useful to have such functionality available in QtQuick/QML. In a distant past, I found it quite easy to write all manner of GUIs for existing Unix functionality using an expect-based subprocess facility integrated into a dynamic object oriented language: http://nielsmayer.com/winterp/examples/subcalc.lsp http://nielsmayer.com/winterp/scrnsnaps/subcalc.gif Niels http://nielsmayer.com _______________________________________________ Qt-qml mailing list Qt-qml@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-qml
