 |
|
I want to connect a signal from QHttp to an object declared in another module. Unfortunately, I can't get rid of the segmentation fault.
Function:
| Code: |
void getServerAddress(uint uid, QObject object, string slot)
{
buffer = new QBuffer();
QHttp http = new QHttp();
object.connect(http, "requestFinished(int,bool)", object, slot); //this line causes segfault
http.setHost("aHost.aDomain.com", 80);
http.get(format("/sth.asp"), buffer);
}
|
And invoking:
| Code: |
class Main : QMainWindow
{
this()
{
setWindowTitle("Some window");
// sth else
getServerAddress(0, this, "serverDataReceived(int,bool)");
show();
}
void slot_serverDataReceived(int, bool)
{
// sth here
}
}
|
Would you help me? |

| I've solved it. I forgot "mixin Q_OBJECT;". |

| It definitely should not segfault but issue a sensible error message. Would you care to post a ticket with the test case? |
