![]() The standard Pro Pen or Pro Pen 2 should give you altitude and azimuth. ![]() How can I get pen altitude, azimuth, and twist data? This intentional abstraction allows for applications to be written to work with any device. There is no way to tell which tablet model is installed on the machine. How can I tell which Wacom tablet model is being used? The good news is that you shouldn't need to as using the WTInfo() function allows you to find what data items are supported by the tablet and what their ranges will be. There is no way to tell if an attached tablet is truly a Wacom tablet. Problems Getting Specific Data How can I tell if an attached tablet is a Wacom tablet? ![]() If you use WTInfo(WTI_DEFSYSCTX.) to get context information with which to create your own context, CXO_SYSTEM will be set and the cursor will move when your application is active. H WintabContext = WTOpen( hWnd, & wintabLogicalContext, TRUE) WintabLogicalContext.lcOptions |= CXO_SYSTEM WWTInfoRetVal = WTInfo(WTI_DEFSYSCTX, 0, & wintabLogicalContext) If you use WTInfo(WTI_DEFCONTEXT, …) to get context information with which to create your own context, CXO_SYSTEM will be clear unless you set it before calling WTOpen(). If this bit is not set, then Wintab will not move the system cursor when your application is active. The CXO_SYSTEM bit of the lcOptions field of your logical context controls whether Wintab moves the system pointer (screen cursor) when your context receives tablet data. WTPacket(hWintabContext, wPacketSerialNumber, NULL) Why does/doesn't the screen cursor move when I use the tablet while my application is running? WTPacketsGet(hWintabContext, VALUE_LARGER_THAN_YOUR_QUEUE_SIZE, NULL) You can help prevent the queue from overflowing by always removing packets from the queue when you receive a WT_PACKET message and by flushing the queue when you receive WT_PROXIMITY messages. If the queue is full, Wintab discards the packet and does not send your application a WT_PACKET message to tell you that your context received a tablet packet. Wintab only adds new packets to the queue and sends your application a WT_PACKET message if the queue is not full. Each Wintab context has a queue of tablet packets. You are probably missing tablet packets because your context's packet queue is overflowing. Why do I suddenly stop receiving WT_PACKET messages from the tablet or seem to only get some of the tablet packets? You will find links to these examples on GitHub. There are many sample code examples for the use of Wintab. Problems Getting Started Where can I find sample code for Wintab?
