Is there planed such feature:
when I type parameters for procedure, function, method, that in hint
window is displayed name and type of expected parameter ?

There is, look at Environment - Options - Editor - Automatic features
- tooltip expression evaluation

Hm, is there, is checked, but I see nothing when I write code.
For example when I write:
  SQLQuery1.SQL.Text:=copy(
here I expect hint for parametes for copy function:
 S; Index, Count: Integer
...

Try Shift-ctrl-space while the cursor is inside the brackets.

Or whatever key combo is assigned to:
"Key-Mapping" => "Code tool Commands" => "Show Code Context"

Yes it works, thanks.
But not for copy() function, which I tested ... interested!
Automatic (Delphi like) showing tooltip, without need of pressing
Ctrl+Shift+Space is not possible ?

I support Lacak2's feelings; I'm using Lazarus for 8-10 hours per day
on a fairly big & complicated project, and also miss the automatic
display from Delphi...

Where in the Lazarus sources would the best starting point be to find
how to implement this ?

I found that automatic features like this won't work if the source has
errors. For the Copy function, I think it's because it's not a true
function, but instead a special keyword that will be replaced by the
compiler with the proper function call. That's why Copy works
perfectly for arrays.

Looks like this feature stopped working in 0.9.26-2. Can anyone else
confirm or put me out of my misery?

I don't know about 0926, but it works in 0927 (daily snapshot). 0927
also works for copy and similar.

Just weird.

I changed the key combination to alt+shift+right. That worked. I used
to have ctrl+shift+right. I last set it up in 0.9.22 and kept on
copying the xml prefs files ever since on new installations.

Maybe my IceWM has some special bla-bla for ctrl+alt key combinations.

Well, at least I'm out of my misery now.

This calls for celebration, excuse me while I open my bottel of
Wyborowa (you see i have been miserable for a while since not been
able to use the paramter hint)
