GNOME Bugzilla – Bug 130204
Tablet support broken on Windows
Last modified: 2004-12-22 21:47:04 UTC
Tried with latest stable and 1.3.23. Neither worked properly with WACOM USB human interface device with mouse or pen. This device is a tablet that a mouse or pen can be used with. This device seems to work properly with all other software. 1.3.23 the mouse icon follows the input device, but the tracing ruler arrows do not when trying to draw an image. The arrows do follow when the cursor is moved into the ruler area. Please let me know any other information you need to try and fix this problem. FYI - This is on a dual monitor system.
Support for drawing tablets is up to the toolkit. Reassigning to GTK+, perhaps the GTK+ developers can help you with this.
Hmm, does your device work as a normal mouse? Did you enable the device in the "input devices" in the preferences? Does your input device show up in the "Device Status" dialog?
Tablet support in GTK on Windows is known to be incomplete, or even broken. To bypass the tablet-aware code, pass the --ignore-wintab command line switch to GIMP (or any other GTK application). Your tablet pen should then work just like a mouse (i.e., no pressure or tilt input), which is better than not at all...

As I just bought a tablet (Acecat Flair USB) which isn't working under gtk2 in Windows, I would like to see if I can help solving this bug. I would appreciate pointers to any information available. Especially the following: 1. A pointer to the WinAPI that is handling tablet input. 2. A pointer to the gtk API that deals with reading tablet input. 3. A gtk test program that can be used for testing.
Tablet input is handled through the WinTab API, see www.pointing.com. The code in GTK that handles this is in gdk/win32/gdkinput-win32.c. There is tests/testinput.c. I don't remember how well it builds on Windows. Or you could just test with the GIMP. Anyway, many (most?) of the tablet-relatd problems in gdk/win32 have been fixed, and the fixes are in GTK 2.4.3. See bug #143240, bug #143237, bug #142943, and bug #138341 . This bug presumably can be resolved as a duplicate of bug #138341, for instance. *** This bug has been marked as a duplicate of 138341 ***
BTW, if Dov's problem is specifically that the Acetat Flair doesn't work in GTK+ 2.4.3 (even if Wacom tablets work), open a new more specific bug for that.
