Using QObjects in namespaces

SQEW

Hi,

I'm fairly new to C++ (coming from Java) so this question might be more related to that instead of Qt.
Please bear with me :)

I want my application to have a globally available method that receives a QString for use with text-to-speech. For this, I need a QProcess which launches espeak with the string as an argument.

I understand using a namespace is the recommended way.

So I have;

voice.h
namespace voice
{
void speak(QString text);
}

voice.cpp
namespace voice
{
void speak(QString text)
{
// ... use a QProcess
}
}

So from here on, every class which includes voice.h can use the namespace method using voice::speak. Excellent.

I'm not sure how to define the QProcess here though. In a class, I would define a private QProcess pointer and then create it in the constructor using new.

So what is the recommended method using a QProcess in this case and how would I define it?
Ideally, this pointer would be private, and I would also need to connect some of it's signals to private slots.

Thanks!

Global functions in namespaces or not is not what I'd recommend. Why not just a class with a static member?

@
class Voice {
public:
static void speak(QString text) { QProcess::startDetached(/.../); }
}

Hi,

Not directly related to your question (although I would say it depends on the use case) but are you trying to implement some sort of accessibility feature ? If so, Qt provides a module for that that you could use
