If I understand you correctly, the "value tree" is that appears in the 
variable window?
If yes, then how some variable appears there? By right clicking on it in the 
source window and choosing "evaluate" or "watch"? And thus it stays there 
forever. And if I choose "evaluate" it stays and makes me think that this is 
the value, which may already be changed. And to remove it, I must choose the 
menu...

Contrary, typing in the gdb console "p X" in 99% of the cases does the work.
What I meant in my first mail is to pass to the gdb simple command "p X", 
where X is the variable under the cursor. And gdb knows very well which type 
is X. And it needs not be only the built-in C, as you mentioned. It knows all 
the types, classes, enums, defines, etc. defined in the executable.
