I had tried that before posting. That serves no useful purpose. The result is shown here.

Notable, it had no impact on the Directory Change pop-up either, so there must be some configuration files, for either tkEclipse or TclTk itself which would allow me to change the defaults. Is there at "tweak" tool, like for GNOME Tweak that would manage the TclTk preferences for various colours?

Answer 1

I can only imagine that this is caused by your desktop environment using some kind of "dark" mode/theme. Normally, all text in tkeclipse is black.

To check whether the problem is with the underlying Tcl/Tk toolkit, try from a shell:

$ wish
% tk_chooseDirectory

This should pop up a readable directory chooser, but apparently doesn't in your environment. I think this is because some "theme" setting of your desktop changes the default colours for Tk applications, leading to non-contrasting fore/background combinations. Changing your desktop theme might help.

What you can try from within tkeclipse itself is to open Tools/TkECLiPSe Preference Editor and set a Default background colour for widgets. Something light, e.g. lightgrey or azure will probably work best.
