Could it be possible to make Qt ready for network transparency ?
Imagine you would add a virtual commandline interpreter to QWidget.

class QWidget : public QObject
{
//<snip>
public slots:
virtual void commandlineInterpreter(QString *command);
//<snip>

public:
signals:
virtual void commandlineResponse(QString *response);
//<snip>
};

Now you could tell every widget what it should do.
Examples:
command = setGeometry(10,10,200,100)
response = ok>
command = setToolTip("hello world")
response = ok>
command = hide()
response = ok>
command = isVisible()
response = true>
command = anUnimplementedFunction("nonsens")
command = not implemented>
...

In our project http://pvbrowser.org we do something similar but
we can't change QWidget.
Instead we have implemented a global commandline interpreter and
have to code something like the above for each widget by hand.

Of course it would be much easier with an commandline interpreter like the above.

What do you think about such a feature ?
Wouldn't it be great ?

Eventually this could work.
I will have a look at it.

For me it must be possible to call scripting code giving the code a QWidget* pointer.
I was thinking on using something like http://www.lua.org/ which can be embedded in a C/C++ host program.
If the Qt Widgets could be wrapped with http://swig.org we were done.
But i doubt if it is possible because of signals and slots.
