Nope, it isn't. That was a typo in the definition of the stylesheets for QT widgets. Thanks for the report. I fixed it, but that particular style attribute (WIDGET_STYLE_GREY) isn't used anywhere... when do you see the messages exactly?

Fixed. Now everybody defaults to the base class implementation in qt_widget_rep which just prints some warning.

This is due to unhandled SLOT_REFRESH message.
In general, at this point of the development of the Qt port it is better not to crash for unhanded messages or queries to the widgets. So in the base class we should ignore any unhanded message and if the debug flag is on just signal this events in the console.

I am on the daily svn version.

Step to reproduce:

  • open TeXmacs;
  • click on the color selection tool in the toolbar;
  • click on "Palette";
  • click on "Ok" (in the Palette windows);

It crashes as follows :
$ texmacs
TeXmacs] Loading corktounicode
TeXmacs] Loading cork-unicode-oneway
TeXmacs] Loading tmuniversaltounicode
TeXmacs] Loading symbol-unicode-oneway
TeXmacs] Loading symbol-unicode-math
TeXmacs] With linked TrueType support
TeXmacs] Loading corktounicode
TeXmacs] Loading unicode-cork-oneway
TeXmacs] Loading tmuniversaltounicode
TeXmacs] Loading unicode-symbol-oneway

TeXmacs] Fatal error, no default implementation
TeXmacs] Crash report saved in /home/poulain/.TeXmacs/system/crash/crash_report_34
TeXmacs] Current buffer report saved in /home/poulain/.TeXmacs/system/crash/crash_report_34_tree
