GUD tooltip display

[Eli Zaretskii]

Could gdb-ui.el be extended to display class members in a tooltip?

Currently, when the mouse pointer is above a class name, the tooltip
says something like "(Class foo *) 0x12345678".  Could it instead
display the result of "ptype foo" or "ptype *foo?  It seems like other
visual debuggers do that.

Also, for simple scalar variables, the tooltip says "$1 = 12345".
Isn't it better to say "foo = 12345" (where `foo' is the variable's
name)?  Convenience variables such as $1 are for GDB command-line
junkies, visually oriented (and command-line challenged) users might
become confused by the $1 thingy; OTOH, displaying the variable's name
could help if, e.g., the pointer is on the wrong token, or if the
expression under the pointer is not well defined or obvious.

WDYT?
