Devel GTK GtkVersion
Sometimes you want to know which version of GTK your Eclipse runs on, because certain versions of GTK may make Eclipse behave in different ways.
There are multiple ways of finding out:
In Eclipse
Help -> About -> Installation Details -> Configuration Tab.
Look for "gtk.version":
On GTK3:
org.eclipse.swt.internal.gtk.version=3.20.3
On GTK2:
org.eclipse.swt.internal.gtk.version=2.24.30
This is often near line 84, but may vary depending on your setup. You can copy the text and search for it in your text editor.
Note, if this line is missing altogether, you’re (very most likely) running Eclipse on GTK2.
Hover over Eclipse, press Ctrl+Shift+D (or Ctrl+Shift+D).
In the general Tab, the GTK version is mentioned.
Note, GTK Inspector is only available GTK3.14 and onwards. Thus the key-combination above only works for these versions of GTK
Usually Eclipse would use the GTK that is found on your system. The system GTK can be found out via pkg-config:
On Fedora:
pkg-config --modversion gtk+-3.0
On ubuntu:
dpkg -l libgtk2.0-0 libgtk-3-0
However, if you have both GTK2 and GTK3 installed on your system, then Eclipse will use the one that is specified by your init file or failing that default for your linux distribution (which may vary).
Eclipse reads which version of gtk to use in it's init file. The init file can be in two different locations.
- If you downloaded eclipse bundle from the website, it can be found in the directory of the executable eclipse:
./eclipse.ini
- If you installed eclipse (e.g through yum/dnf), it will be located in your /etc/ folder:
/etc/eclipse.ini
