I am trying to locate the source code for this settings page. I want to build an annotation program using this implementation because it is very smooth.

Wacom Tablet settings on Gnome 3

Looks like it is in https://github.com/GNOME/gnome-control-center/tree/master/panels/wacom and possibly https://gitlab.gnome.org/GNOME/gnome-settings-daemon/tree/master/plugins/wacom too.

https://github.com/GNOME/gnome-control-center/blob/master/panels/wacom/gnome-wacom-panel.desktop.in.in has a gnome-control-center wacom EXEC and sure enough running that launches that settings panel!

    Simple and smooth implementation, I love it! Didn't know it was there there. Note that the actual drawing area logic is located in cc-drawing-area.c and takes mere 200 lines. – undercat Feb 22 at 0:24
  • Super appreciate the further guidance, I don't know much about C programming yet and it would have taken me a while to figure that out that it was in cc-drawing-area.c, although that makes sense now that you mention it. Still wondering where all those other parts are used. – Elijah Lynn Feb 22 at 1:10

    Happy that helped! Just to clarify how I found it, I simply looked up where in the source code the test button's text was assigned ("Test Your _Settings") and followed the use/definition chain (cc_wacom_panel_constructed()=> cc_drawing_area_new() => CC_TYPE_DRAWING_AREA and finally the G_DEFINE_TYPE macro in cc-drawing-area.c). It's very simple, though OOP done in C can be a bit confusing at first. – undercat Feb 22 at 1:56
  • Thanks, how did you know to put a _ in front of the settings? – Elijah Lynn Feb 22 at 2:10

    It's a way to specify the hotkey for a button, you'll see on the screen it if you hold Alt. Github's search is fuzzy so it should find it either way, locally you could find it with something like git grep -Ei "test\W+your" *.c or a fuzzy search tool like agrep without knowing it was there. – undercat Feb 22 at 9:33
