Summary: wxGtk uses private API, breaks with gtk 2.11.6

Initial Comment:
Hi,
wxGtk uses private Gtk API in src/gtk/settings.cpp at least. The GtkTooltips->tip_window field is marked private[0] and it's use in Gtk was stopped with version 2.11.6, thus it's always NULL now.

This makes gtk_widget_ensure_style(tooltips->tip_window) print a critical warning and the pointer dereference one line below gives a segfault.

The change in Gtk is [1]. Please fix this ASAP, otherwise many users will get a broken wxGtk soonish when all distributions switch to 2.12.

Bye

Thanks for the note - good to see that it's fixed in GTK+ but at least now
wxGTK apps won't crash for GTK+ versions prior to 2.11.6, although the
tooltip colour will be hard-coded to something arbitrary.

Julian,

in Fedora 8 development gtk 2.11.6 a patch from upstream svn has been
added, which reintroduces the old GtkTooltips API (in particular the
tip_window pointer), so that wxGTK (and e.g. acroread) don't crash.

Thanks, I've committed a fix to stop it from crashing, but since I don't
know how to get the colour I'll leave this bug report open: perhaps Robert
or Mart can comment.
