- (void)handleTabletEvent: (NSEvent *)theEvent
{
NSEventType eventType = [theEvent type];
if (eventType != NSTabletPoint && [theEvent subtype] != NSTabletPointEventSubtype)
return; // Not a tablet event.
ulong timestamp = [theEvent timestamp] * 1000;
QPointF windowPoint;
QPointF screenPoint;
[self convertFromScreen:[NSEvent mouseLocation] toWindowPoint: &windowPoint andScreenPoint: &screenPoint];
uint deviceId = [theEvent deviceID];
if (!tabletDeviceDataHash->contains(deviceId)) {
