Success :)
To remove clipboard error, i disabled clipboard in source code :
void QWasmClipboard::initClipboardEvents()
{
if (!hasClipboardApi)
return;
/*val permissions = val::global("navigator")["permissions"];
val readPermissionsMap = val::object();
readPermissionsMap.set("name", val("clipboard-read"));
permissions.call<val>("query", readPermissionsMap);
val writePermissionsMap = val::object();
writePermissionsMap.set("name", val("clipboard-write"));
permissions.call<val>("query", writePermissionsMap);*/
hasClipboardApi = false;
}
Clipboard permission is not managed on my firefox (63.0.3 64bit).
And to the blank page, i used QQuickView with resizeMode at SizeRootObjectToView :
QQuickView* view = new QQuickView();
view->setResizeMode(QQuickView::SizeRootObjectToView);
view->setSource(QUrl(QStringLiteral("qrc:///main.qml")));
view->show();
