Description Antonin Nebuzelsky 2005-07-25 15:24:03 UTC 
Editor hints are recomputed unnecessarily in the following scenarios:

(1) Each time I move cursor within the line where a hint is displayed, the hint
icon disappears and then appears again after I stop moving the cursor. The icon
should stay displayed until I make a change or until I move cursor out of the line.

(2) Repetitively moving cursor to a certain line makes the hint icon appear on
that line with the same delay, several hundreds of milliseconds, as the first
time I go to the line. I guess the hint is computed again and again each time.
It should be cached for the line until a modification is made in the code.
Comment 1 Tomas Hurka 2005-07-25 16:44:38 UTC 
This is as designed. 
(1) Was requested by HIE. 
(2) Cashing would be very dangerous, since potentially any modification in any place can change such 
cached hint.
Comment 2 Tomas Hurka 2005-07-25 16:52:04 UTC 
BTW: Ad (2) If there is no modification the information is already cached by MDR infrastructure.
Comment 3 Antonin Nebuzelsky 2005-07-25 21:31:03 UTC 
I don't see (1) specified in UI spec. Show me where this is specified before
closing the issue. Flashing icon on the line where I move cursor is annoying.
Comment 4 Martin Matula 2005-07-26 08:24:17 UTC 
This was explicitly requested by Jano Rojcek along with moving the light bulb
icon on top of the text rather than on top of the code folding. This is a
similar behavior that can be found in other products that show the light bulb on
top of the text - this way the user is not disturbed by the light-bulb when
typing or moving the cursor - it does not cover the text.
It is possible that this detail is not captured in the UI spec. Pavle, please
add it.

Spec. updated.
