A previous article explained how to get online and offline help for GTK+ using a web browser. Devhelp is an alternative application to using a web browser to view help files.

With Devhelp it is not necessary to navigate to the folder that contains the off-line documentation, the documentation is accessed in the left pane of Devhelp as shown in the above image.

One thought on “GTK+ 3 Reference Manual in Devhelp Viewer”

  1. When I decided to create GUIs for some C programs I built for home automation, I found C is not listed as a language binding. I have no interest in learning a new language just to build GUIs. Then YouTube helped me find your content. Thank goodness for that. So far I’ve installed the basic (and extended) tools, and viewed the first 5 tutorial videos. Much appreciated you created these guides!
