    XMLWordPrintable

Details

    • WebAssembly
    • 8d11e05f8 (dev), 62f83ac45 (6.5), ea4501366 (tqtc/lts-6.2)

    Description

      Add this line the main() function of any WASM project and run it on a device that has no touchscreen (for example, a basic desktop PC):

      qDebug() << "Devices:" << QInputDevice::devices();

      The browser's Developer Console will print something like this:

      Devices: QList(QPointingDevice("touchscreen" TouchScreen id=1 ptrType=Finger caps=Position|Area|NormalizedPosition maxPts=10))
