Trying to debug a GTK theme, I modified. Having corrected most of the issues with the theme, I Still cannot figure out, what color setting is responsible for background color in some input-fields or text-views.

SETUP

I can start GtkInspector as well as gtkparasite with Gtk3 applications (starting those debuggers as described on the given pages).

I'm sure, the debugger attached to the right application, because I can

  • change the program's theme
  • show graphic updates
  • show pixel cache ...

PROBLEM

In the left selection pane (widget-treeview expected) is only one element: "GtkSettings"

Tried with:

  • meld
  • synaptic
  • wireshark
  • zenity --calendar

EXPECTED BEHAVIOR:

Be able to

  • select widgets either from the missing widget-treeview, or when locating them with the 'target button'
  • examine and change their parameters

SYSTEM INFORMATION

OS & all programs / packages: Debian 8 x86_64 (up-to-date: 09.01.2015)

QUESTION

  1. How can I debug my GTK-theme?

  2. Does anyone else experience problems with the GtkInspector (is this a bug)?

  • Did you use the "inspect" button and click on a widget? – ptomato Jan 10 '15 at 06:46
  • This [screenshot](https://hitzkopf.at/files/GTK-inspector.png) shows, how my Gtk Inspector looks like. If you mean the "Select an Object" button on the left top - yes, I tried that. – Florian Jan 10 '15 at 09:46

I had the same problem with GtkInspector on Debian Jessie and I solved it by calling terminal and typing next :

gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true

this enables GtkInspector shorcut buttons just run your application and press 

Control-Shift-I or Control-Shift-D

I hope it helps

    That just works :') - Tnx! (Don't know why this is necessary, though) – Florian Jan 22 '15 at 09:31

    I have the same problem as described in the question. When I try to run the suggested command under Debian Jessie I get `No such schema 'org.gtk.Settings.Debug'`. – cgogolin Jun 15 '15 at 12:06

    @cgogolin you have to install `libgtk-3-dev` to get the debug schema. – Léo Lam Dec 13 '15 at 11:18
  • @LéoLam - Nope, installing that made no difference. It's already installed. I also get No such schema. – hookenz Mar 28 '16 at 20:51
  • But these shourtcuts are working as per the applications opened. For example if I want to inspect VS Code and I open it and press Ctrl+Shift+I then it formats the files and Ctrl+Shift+D opens the Debug menu. Same issue with the browsers. So how to open GTK inspector in these cases? – Jignesh M. Khatri Jun 27 '21 at 09:25

https://wiki.gnome.org/Projects/GTK%2B/Inspector misses to tell people to install "libgtk-3-dev"!!!

  1. Install the package [https://packages.debian.org/search?arch=amd64&keywords=libgtk-3-dev libgtk-3-dev]

  2. Start from terminal with:

    GTK_DEBUG=interactive gedit/gnome-terminal/nautilus/etc
