QT application (SI_POLL problem)

[versatophon]

Hello,
I develop a QT application under Windows XP and I want to use SI_POLL to get informations from my spacemouse. The problem is SiOpen function returns SI_BAD_VALUE and I don't kwon why.

Code: Select all

SiOpenData oData;

   if (SiInitialize() == SPW_DLL_LOAD_ERROR) 
   {
      button1->setCheckState(Qt::Checked);//to check errors
    } else if ((spaceHandler = SiOpen("SpaceMouse", SI_ANY_DEVICE, SI_NO_MASK, SI_POLL, &oData)) == NULL) {
       button2->setCheckState(Qt::Checked);//to check errors
    } else {
      SiClose(spaceHandler);
    }




With SI_POLL, if I don't use a SiOpenData, the program crashes.

I maybe made something wrong. Someone could explain to me what is the problem??

Hi versatophon,

SI_POLL has not been implemented. Only the event-driven model works. If needed, you might want to set up a separate thread to get the events from the device.
