Thanks for your reply.  I didn't provide enough information last time, sorry about that.



Let me start over, with an example and some brief code.



Below is some simple code to bring up a shell with a TextField widget in it.



When I initialize the TextField widget, I change the code to use 1 of the 2 listed translations:



  translations_copypaste:  This translation table calls the built-in actions for paste-clipboard, copy-clipboard, and cut-clipboard when the familiar ctrl-c, ctrl-x, and ctrl-v are pressed.



  translations_ignore:  This translation table always calls ignore_cut_paste() when the same keys are pressed.  This function just prints a message to the console ("Ignoring") so I know it's working.



This is almost the entire program.  All that is missing is initializing the parent and the app_context.





What happens is:



On Windows 7 Professional:

Both translation tables work as expected:

translations_ignore: Correctly causes the text "Ignoring" to print every time ctrl-c, ctrl-x, or ctrl-v are pressed.

translations_copypaste:  Correctly causes text in the small window to cut/paste/copy as expected and is integrated with the system clipboard.



On Windows 11 Enterprise:

translations_ignore: Correctly causes the text "Ignoring" to print every time ctrl-c, ctrl-x, or ctrl-v are pressed.

translations_copypaste:  My application (not the X-Server) crashes every time ctrl-c, ctrl-x, or ctrl-v are pressed.  The X-Server seems to continue running.





I don't know how to debug this further...

  it seems like the translation table is working, since the "ignore" translation table works...

  also, everything works perfectly on Windows 7 professional, so it seems like the "should"" be OK.





Code:




void ignore_cut_paste(Widget widget, XEvent *event, String *args, int *num_args)
{
  printf("Ignoring\n");
}

void TestPaste(Widget parent)
{
  Widget thewin,rowcol,textarea;
  XtActionsRec actions2;

  actions2.string = "ignore_cut_paste";
  actions2.proc = (XtActionProc)ignore_cut_paste;
  XtAppAddActions (app_context, &actions2, 1);

  String translations_copypaste = "#override\n Ctrl<Key>v:  paste-clipboard()\n Ctrl<Key>c:  copy-clipboard()\n Ctrl<Key>x:  cut-clipboard()";

  String translations_ignore = "#override\n Ctrl<Key>v:  ignore_cut_paste()\n Ctrl<Key>c:  ignore_cut_paste()\n Ctrl<Key>x:  ignore_cut_paste()";

  thewin = XtCreatePopupShell("Test", topLevelShellWidgetClass,parent,NULL,0);

  rowcol = XtVaCreateWidget ("rowcol",xmRowColumnWidgetClass, thewin, NULL);

  textarea = XtVaCreateManagedWidget ("test_area",
                                  xmTextFieldWidgetClass, rowcol,
                                  XmNmaxLength,        80,
                                  XmNtranslations,     XtParseTranslationTable ( translations_copypaste ) ,
                                  NULL);
  XtManageChild(textarea);
  XtManageChild (rowcol);
  XtPopup(thewin,XtGrabNone);
}

I'm assuming this means "the X server crashes", but it's not exactly clear.



If that is the case, there are some instructions on generating backtraces to help with debugging at [1].

It's not really safe to make assumptions like this. This could be a latent bug in XWin which just happens to get exposed on W11 (or that particular system, even)...
