           Summary: Issue with Delete when NumLock active
           Product: Wine
           Version: 20040716
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: biro_arpad at yahoo.com


Found a possible bug in Wine20040716 on a SUSE 9.1 machine using
standard Hungarian PC keyboard with Hungarian keyboard layout.
The bug shows up both with wine-20040716-SuSELinux91.i586.rpm and
with self-compiled Wine20040716.
The problem is that when NumLock is active, both Del keys perform
a "delete" action _and_ insert a comma (the decimal character in
Hungarian). This means that the character just right to the text
cursor is replaced with a comma when pressing any of the two Del
keys.
What Wine should do instead: the left Del key should perform a
"delete" and the right one should insert a decimal character
(when NumLock is active).

I did some googling and found this:

Since that patch did not work for me (it may have been good for
that version though), I made another one:

          * depending on the NumLock state */
         return nonchar_key_vkey[keysym & 0xFF];
+    }

     TRACE_(key)("e->keycode = %x\n", e->keycode);
--------------------------------------------------------------------

I have no idea as to whether or not this works with other keyboards.
It should definitely be modified somehow, since it has the "comma"
decimal character hard-wired.
Also, the patch may not be optimal at all, so this is really just
for demonstration (it works perfectly here, though).


As a side note: I also tried the following patch, but it does not
work (the left Del is OK (performs a "delete"), but the right one
does nothing):

-    if ((keysym >= 0xFFAE) && (keysym <= 0xFFB9) && (keysym != 0xFFAF)
+    if ((keysym >= 0xFFAC) && (keysym <= 0xFFB9) && (keysym != 0xFFAF) &&
(keysym != 0xFFAD)
