Theme change is disabled (dimmed and inactive), when you hover over the switch, a window appears saying “Theme is hard -coded with GTK_THEME” (unfortunately technically I can’t show the popup in the screenshot). Let’s start GtkInspector again, go to the Appearance tab, try switching the theme. Sudo nano /usr/share/applications/sktopĪdd an entry to it env GTK_THEME=Adwaita:dark and bring it to the form: I prefer and recommend storing various user settings in the home directory, but I will consider both options. The first option is to bind to the root of the system at:įor all users, or the second option, bind to the home directory at:įor the current user. If we need a light theme, the line should look like this:Ī theme can be hardwired in two ways. Where “name application” is the name of the application. The env command (allows you to modify the list of environment variables before executing a user command) in the Exec line. usr/share/applications/"name application".desktop According to the GTK+ manual, you can load a specific theme and its variant (dark, light) per application via the environment variable: GTK_THEME=theme:variant. Now we’re going to try hard -binding Geany to a dark theme. We need to look for another solution, but nothing “Normal heroes always go around” – Aibolit – 66 films. Let’s try restarting the Geany application:Īnd what do we see? The dark theme is not preserved. This is quite an interesting tool and deserves a separate study. You can see for yourself here and play with it. I don’t need it yet (I’ll need it later to test the changes). Go to the Appearance tab and enable the Dark option (or the Adwaita-dark theme):Īs you can see, we got the desired result, in the Geany application, the theme changed to dark. It turns on only in the window with the running application. Or move the mouse cursor over the desired widget and press Control-Shift-I to specifically inspect the widget under the mouse cursor. To launch GTKInspector, focus your GTK application and press Control-Shift-D. Gsettings set enable-inspector-keybinding true On Debian, Ubuntu, first make sure you have the libgtk-3-dev package installed. This application is a tool for testing, modifying and understanding GTK+ applications on the fly. Here we see a dark terminal inside a light application.
Let’s turn on any dark theme in the Geany settings to your taste View => Color schemes.
Further on the link: download the ZIP file with themes, unpack and install (using the install.sh script or copying the themes to the ~/.config/geany/colorschemes/ directory ).
I want it to look something like on the official Geany website: For example, I take the Geany text editor. I also want to do about the same with the application I need. Although in the application settings it can be changed to light. For example, in my light Adwaita, the Eye of GNOME (eog) and Totem applications are displayed in a dark theme:Īlso on the screenshot, I inserted the Celluloid video player, it is not included in the standard set of Gnome applications, but also comes with a dark theme. There are also exceptions for distro builders or GNOME developers. As we know the Gnome-tweak application changes the theme of all applications in the system. As you can see from the title of the article, I want to change the theme of one (or several) GTK applications.
You, depending on the distribution and personal preferences, can have any other theme. In the GNOME desktop, I use the Adwaita light theme.
How to change the GTK theme for an application Also on the Internet you can download and install any themes and icons to your taste. In the spring, the GNOME developers even wrote an open letter asking distro builders not to change the default settings of GNOME applications. The developers of GNOME and many distributions each customize the theme of applications in their own way.
