Description of problem: Opening a dialog in Eclipse (ctrl-F or ctrl-shift-T) does not transfer the focus to the newly opened dialog. You have to click the window in order to be able to type into inputs. Since I did not update my eclipse installation when upgrading to F23, it is either a gtk2 regression or a problem with gtk2/x11/wayland integration. Version-Release number of selected component (if applicable): gtk2-2.24.28-2.fc23.x86_64 How reproducible: Always. Steps to Reproduce: 1. Start Eclipse 2. Type ctrl+shift+T Actual results: Unfocused window opens. Expected results: Focused window opens. Additional info:
We cannot support GTK2 any longer for Eclipse; all development effort is now on GTK3 and Eclipse in Fedora 23 now uses GTK3 by default. I wonder why your Eclipse did not get updated, did you download it from eclipse.org instead of installing from Fedora repositories? The latest Eclipse update from the Fedora repositories contains a large number of patches to fix various GTK problems, please try the latest Eclipse from the Fedora repositories to see if the issue is fixed for you there.
I am using eclipse.org binaries (mostly because I used a self-patched CDT), but: - the problem went away (I did not even notice when) - eclipse seems to use gtk3 now (at least it's mentioned in /proc/pid/maps) Perhaps this got fixed when I updated to Mars.2.
