QProcess state

[patcito]

I have a code to detect browser like this:

QProcess pProcess;
	QString webBrowserCmd;	
int return_value =0;
if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "mozilla-firefox " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}
	// Try with Mozilla
	else if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "mozilla " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}
	// Try with galeon
	else if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "galeon " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}

QProcess pProcess;
	QString webBrowserCmd;	
int return_value =0;
if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "mozilla-firefox " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}
	// Try with Mozilla
	else if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "mozilla " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}
	// Try with galeon
	else if ( return_value !=2 ) {
		webBrowserCmd.clear();
		webBrowserCmd.append( "galeon " );
		webBrowserCmd.append( url );
pProcess.start(webBrowserCmd);
		return_value = pProcess.state();
	}

To copy to clipboard, switch view to plain text mode 

The doc says QProcess::state() return 2 if the process is not running.
If the browser doesn't exists I try another one, I use pProcess.state() value for this but I'm note sure it will return 1 or 2 in case of failure. Will it always return 2 if the browser doesn't exist? I'm afraid it could return 1 because the process might still be running even if the command failed. Any idea if this is the right way to do it?

Thanx in advance

How about searching $PATH to locate appropriate commands?
