[Qt-interest] how can I call a SLOT function and abitrary value parameter.

[Giancarlo Amati]

Hello everybody,

I made my GUI in which I have a main menu. One of the voices has 2 possible suboptions to be chosen:

VolumeRendering ---> MIP
                         |__>COMPOSITE VR


so I created the correspondent Actions and then I have my CMainWindows class derived from a QMainWindow where I added one slot:

OpenVR(int opt) where I would OPT be 1 if MIP is chosen, or 2 if COMPOSITE_VR is Chosen.

now I to create the signal connection I wrote:

QObject::Connect(Ui.ActionMIP,SIGNAL(triggered()), myWin, SLOT(OpenVR(1)));
QObject::connect(Ui.ActionCOMPOSITE,SIGNAL(triggerer()),myWin,SLOT(OpenVR(2)));

where OpenVR(int opt) is a slot fuction created in CMainWindows class.

Compilation is OK, but unfortunately the Connect returns error message like "OpenVR (2)" doesn't exists. So my question is how can I call a SLOT function and passing MY arbitrary value depending on the voice in my menu?

Kind Regards.
